Vascular disorders: flow, pressure, and vessel integrity.
The Vascular Highway: Arteries, Veins & When Traffic Stops
Welcome back! In Part 1, you mastered the heart's structure and electrical system. In Part 2, you learned what happens when the heart factory fails — CAD, MI, heart failure, and hypertension.
Now in Part 3, we leave the heart factory and travel the Vascular Highway System — the massive network of arteries and veins that carry blood to every cell factory in your body. You will learn what happens when highways get blocked (PAD), when traffic clots (DVT), when a clot travels to the lungs (PE), and when highway walls balloon out (aneurysms).

🖥 The Vascular Highway System Overview
The vascular system is a closed highway loop. Arteries carry O₂-rich blood OUT, veins carry used blood BACK. Problems at any point can be life-threatening.

Section 1: The Vascular Highway System — Overview
Understanding arteries, veins, and capillaries as the body's transportation network
🏭 The Vascular Highway — Cell Factory Concept
Imagine your body as a massive industrial complex with millions of cell factories. Every factory needs supply trucks delivering oxygen and nutrients, and waste removal trucks hauling away carbon dioxide and metabolic waste.
The vascular system is this transportation network! It has three types of "roads":
Arteries = HIGH-SPEED HIGHWAYS — Thick, muscular walls that carry oxygen-rich blood AWAY from the heart at high pressure. They have their own smooth muscle cells that can constrict or dilate to control traffic flow.
Capillaries = LOCAL DELIVERY STREETS — Tiny, thin-walled vessels where the actual exchange happens. Oxygen and nutrients pass through to cell factories, and CO₂ and waste are picked up. Only ONE cell thick!
Veins = RETURN ROUTES — Thin-walled vessels with ONE-WAY VALVES that carry deoxygenated blood BACK to the heart. They depend on skeletal muscle contractions to push blood uphill against gravity!
🔬 Artery vs. Vein: Cross-Section Comparison
Arteries have thick muscular walls for high-pressure flow. Veins have thin walls, larger lumens, and ONE-WAY VALVES to prevent backflow. This is WHY vein problems involve swelling and valve failure!
🏭 The Key Cell Factories in Part 3
🧰 Vascular Smooth Muscle Cell
Job: The "Traffic Controller" — constricts and dilates blood vessels to control blood flow and pressure.
Brown discoloration (stasis dermatitis). Warm skin. Cyanotic when dependent.
Pulses
Decreased or ABSENT!
Present (normal)
Edema
Minimal or absent
SIGNIFICANT edema! Ankle swelling is prominent.
Skin/Hair
Shiny, dry, scaly. Hair loss. Thickened toenails.
Stasis dermatitis. Brown pigmentation.
Ulcers
Between/on toes or top of foot. PAINFUL! Deep, pale base.
Around ankles (medial malleolus). Uneven edges. Pink bed with granulation.
Leg Position
Keep legs LEVEL or slightly DEPENDENT. Do NOT elevate above heart!
ELEVATE legs! Helps blood return to heart.
Temperature
COOL or COLD
WARM
💡 Memory Trick: Arterial vs Venous
ARTERIAL = "A" for ABSENT pulses, ACHING with activity, pale And cold
VENOUS = "V" for VISIBLE edema, VARICOSE veins, and ELEVATE to help!
Leg Position Rule: "Arteries go DOWN (or level), Veins go UP!" — Arterial disease = keep dependent to let gravity help blood flow down. Venous disease = elevate to help blood return against gravity.
💜 LPN Scope: Vascular Data Collection
LPNs COLLECT DATA and REPORT! RNs ASSESS and DIAGNOSE!
Monitor peripheral pulses — Check pedal, posterior tibial, popliteal, and femoral pulses. Report absent or diminished pulses immediately!
Check the 6 P's of Neurovascular Status:Pain, Pallor, Pulselessness, Paresthesia (numbness/tingling), Paralysis, Poikilothermia (cool temperature)
Measure and compare circumference of both legs
Monitor skin for color changes, temperature differences, ulcers, hair loss
Report any abnormalities to the RN and PHCP immediately
⚠️ The 6 P's of Neurovascular Compromise
The 6 P's are your QUICK ASSESSMENT checklist for any vascular concern. If ANY P is abnormal — REPORT to the RN and PHCP immediately!
🎯 NCLEX Clinical Judgment: Recognizing Cues
When the NCLEX asks you to "recognize cues" for vascular problems, look for these patterns:
ARTERIAL cues: Cold extremity + absent pulses + pain with activity + pale/gray skin + hair loss = think PAD or acute arterial occlusion
VENOUS cues: Warm, swollen extremity + brown discoloration + aching after standing + edema = think DVT or venous insufficiency
PE cues: Sudden chest pain + dyspnea + tachycardia + anxiety + history of DVT or immobility = think pulmonary embolism — EMERGENCY!
Aneurysm cues: Pulsating abdominal mass + bruit + back/abdominal pain = think aortic aneurysm — DO NOT PALPATE!

Quiz 1: Vascular Overview (15 Questions)
Score 80% to unlock Peripheral Arterial Disease!
Q1
The LPN is collecting data on a client with peripheral vascular disease. Which finding is MOST characteristic of ARTERIAL disease?
A. Significant ankle edema
B. Brown skin discoloration at the ankles
C. Decreased or absent peripheral pulses
D. Warm, reddened skin on the affected extremity
✅ Correct: C. Decreased or absent peripheral pulses is the hallmark of arterial disease because atherosclerotic plaque narrows or blocks the artery, reducing blood flow. Options A, B, and D are all signs of VENOUS disease. Cell Factory Connection: When the arterial highway is blocked, supply trucks (blood) cannot reach downstream cell factories, so pulses disappear. LPN Action: Check pedal and posterior tibial pulses bilaterally and REPORT absent pulses immediately.
Q2
A client with vascular disease has pain that occurs when walking and is relieved by rest. The LPN recognizes this as:
A. Intermittent claudication
B. Rest pain
C. Phantom limb pain
D. Venous stasis pain
✅ Correct: A. Intermittent claudication is pain in the muscles during activity (walking) caused by inadequate blood supply through narrowed arteries. It is relieved by rest because the muscle demand for oxygen decreases. Rest pain (B) occurs at night when the client is lying down. Cell Factory Connection: During walking, muscle cell factories need MORE oxygen. If the highway is blocked, they cannot get enough, causing ischemic pain. LPN Action: Reinforce instructions to walk to the point of claudication, stop and rest, then walk a little farther to develop collateral circulation.
Q3
Which leg positioning instruction is correct for a client with peripheral ARTERIAL disease?
A. Elevate legs above the level of the heart
B. Keep legs level or in a slightly dependent position
C. Keep legs elevated on three pillows at all times
D. Cross the legs at the ankles while sitting
✅ Correct: B. In peripheral arterial disease, the legs should be kept at heart level or slightly dependent (hanging down) because elevation above the heart slows arterial blood flow to the feet. Gravity helps blood flow DOWN to the starving tissues. Do NOT elevate above heart level. Crossing legs interferes with blood flow. Memory Trick: Arteries go DOWN, Veins go UP!
Q4
The LPN is monitoring a client with deep vein thrombophlebitis. Which finding requires IMMEDIATE notification of the RN?
A. Mild calf tenderness
B. Ankle edema
C. Sudden shortness of breath and chest pain
D. Warm skin on the affected leg
✅ Correct: C. Sudden shortness of breath and chest pain in a client with DVT indicates a possible pulmonary embolism — a LIFE-THREATENING emergency! The clot has broken free and traveled to the lungs. Options A, B, and D are expected findings of DVT. LPN Action: Notify the RN and Rapid Response Team IMMEDIATELY. Elevate the head of the bed. Prepare to administer oxygen. This is a PRIORITY report!
Q5
Which layer of the arterial wall contains smooth muscle cells that control constriction and dilation?
A. Tunica adventitia
B. Tunica intima
C. Tunica media
D. Endothelium
✅ Correct: C. The tunica media is the MIDDLE layer of arteries and contains smooth muscle cells that constrict and dilate to control blood flow. This is the thickest layer in arteries. The tunica intima is the inner lining (endothelial cells). The adventitia is the outer protective layer. Cell Factory Connection: The vascular smooth muscle cell factory in the tunica media is the TARGET for many drugs: calcium channel blockers relax these cells, alpha-blockers prevent them from constricting.
Q6
The LPN is reinforcing teaching to a client about preventing deep vein thrombosis after hip surgery. Which instruction is MOST important?
A. "Massage your legs frequently to improve circulation."
B. "Avoid crossing your legs and perform ankle pumps regularly."
C. "Keep your legs in a dependent position at all times."
D. "Apply warm compresses to both legs every 4 hours."
✅ Correct: B. Avoiding leg crossing prevents venous stasis, and ankle pumps activate the calf muscle pump to push blood back toward the heart. NEVER massage legs of a client at risk for DVT because this can dislodge a clot! LPN Action: Reinforce use of antiembolism stockings, leg exercises, and early ambulation as prescribed.
Q7
A client with venous insufficiency has brown discoloration along the ankles. The LPN understands this is caused by:
A. Arterial ischemia
B. Poor hygiene
C. Hemosiderin deposits from chronic venous hypertension
D. Fungal infection
✅ Correct: C. Stasis dermatitis causes brown discoloration from hemosiderin deposits. When venous pressure is chronically elevated, red blood cells leak from capillaries into the tissues, break down, and leave behind iron-containing hemosiderin. This is a hallmark of venous insufficiency. Cell Factory Connection: When vein valves fail, blood pools and backs up, increasing pressure in the capillary beds, forcing red blood cells through the vessel walls.
Q8
The LPN collects data on a client and notes the following: cold, pale right foot; absent right dorsalis pedis pulse; pain with ambulation; shiny, hairless skin on the right leg. These findings are MOST consistent with:
A. Deep vein thrombosis
B. Peripheral arterial disease
C. Venous insufficiency
D. Varicose veins
✅ Correct: B. All of these are CLASSIC signs of arterial disease: cold extremity (no blood flow), absent pulses, claudication (pain with walking), shiny hairless skin (chronic ischemia damages hair follicles and skin). DVT presents with warmth and swelling. Venous insufficiency has edema and brown discoloration. NCLEX Cue Recognition: When you see COLD + ABSENT PULSES + PAIN WITH ACTIVITY = think ARTERIAL!
Q9
Veins differ from arteries in that veins have:
A. Thick muscular walls for high-pressure flow
B. One-way valves to prevent backflow of blood
C. Smaller lumens than arteries
D. No connection to the heart
✅ Correct: B. Veins have one-way valves that prevent the backflow of blood. This is essential because venous blood travels at LOW pressure against gravity (from feet back up to the heart). When these valves fail, blood pools = varicose veins and venous insufficiency. Arteries have thick walls (A) and arteries have smaller lumens than veins (C is reversed).
Q10
Which of the following are components of Virchow's Triad for clot formation? Select ALL that apply.
A. Venous stasis (slow blood flow)
B. Elevated blood glucose
C. Endothelial injury (vessel wall damage)
D. Hypercoagulability (blood clots too easily)
E. Low blood pressure
✅ Correct: A, C, D. Virchow's Triad consists of three risk factors for clot formation: (1) Venous STASIS (slow flow), (2) Endothelial INJURY (vessel wall damage), and (3) HYPERCOAGULABILITY (blood that clots too easily). Elevated blood glucose and low BP are not part of the triad. Memory Trick: "SIH" = Stasis, Injury, Hypercoagulability. Think "SIH... I have a clot!"
Q11
The client with a DVT has a prescription for bed rest with the affected leg elevated. The LPN knows that the MOST important reason for elevation is to:
A. Prevent arterial occlusion
B. Reduce edema and promote venous return
C. Dissolve the clot
D. Increase arterial blood flow to the extremity
✅ Correct: B. Elevating the leg above the level of the heart uses gravity to help blood return to the heart, reducing edema and venous stasis. It does NOT dissolve the clot (medications do that). It does NOT affect arterial flow. LPN Action: Elevate the leg as prescribed. Do NOT use the knee gatch or pillows under the knees, as this compresses the popliteal vein.
Q12
The LPN is caring for a client with suspected DVT. Which action should the LPN AVOID?
A. Measuring leg circumference
B. Massaging the affected extremity
C. Applying antiembolism stockings as prescribed
D. Monitoring for shortness of breath
✅ Correct: B. NEVER massage the affected extremity of a client with DVT! Massage can dislodge the clot, causing it to travel to the lungs (pulmonary embolism). Options A, C, and D are all appropriate LPN actions. Safety Alert: Do NOT massage. Do NOT vigorously palpate. Handle gently!
Q13
The endothelial cells that line blood vessels are important because they:
A. Contract to increase blood pressure
B. Provide a smooth surface that prevents clot formation
C. Produce red blood cells
D. Store calcium for muscle contraction
✅ Correct: B. Endothelial cells provide a smooth, non-sticky surface that keeps blood flowing without forming clots. They also release nitric oxide for vasodilation. When the endothelium is damaged (by atherosclerosis, smoking, or IV catheters), the collagen underneath is exposed and triggers clot formation. Cell Factory Connection: The endothelial cell factory maintains the highway surface. When damaged, the road becomes rough and attracts platelets.
Q14
A client with PAD asks why they should avoid applying a heating pad directly to their legs. The BEST response by the LPN is:
A. "Heat increases blood clotting in the area."
B. "The decreased sensation in your legs could cause burns without you feeling them."
C. "Heat will make the arterial blockage worse."
D. "Heating pads are only for venous problems."
✅ Correct: B. Clients with PAD have decreased sensation in their extremities due to poor blood supply to the nerves. Applying direct heat can cause burns that the client cannot feel. Additionally, the poor circulation means the burn will heal very slowly or not at all. LPN Action: Reinforce instructions to use warm socks instead. Never apply direct heat!
Q15
The LPN understands that Virchow's Triad explains the risk factors for developing:
A. Peripheral arterial disease
B. Aortic aneurysm
C. Deep vein thrombosis
D. Raynaud's disease
✅ Correct: C. Virchow's Triad (venous stasis, endothelial injury, hypercoagulability) specifically explains the pathophysiology of venous thrombosis (DVT). PAD is caused by atherosclerosis. Aneurysms are caused by weakened vessel walls. Raynaud's is caused by vasospasm.
When the supply highways get blocked — PAD, Raynaud's, and Buerger's Disease
🏭 PAD: When the Supply Highway Gets Blocked
Peripheral Arterial Disease (PAD) is a chronic disorder where partial or total arterial occlusion deprives the lower extremities of oxygen and nutrients. Tissue damage occurs BELOW the level of the blockage.
The #1 cause of PAD is atherosclerosis — the same plaque buildup you learned about in Part 2, but now it is happening in the leg arteries instead of the coronary arteries!
Cell Factory Explanation:
Think of the leg arteries as supply highways to millions of muscle and skin cell factories in your legs and feet. When atherosclerotic plaque builds up and narrows these highways, the delivery trucks (red blood cells carrying oxygen) cannot get through. The cell factories downstream starve for oxygen, causing pain, tissue damage, and eventually gangrene if untreated.
Critical threshold: When an artery is narrowed by 50% in the left main or 75% in any major branch, the blockage is considered significant.
🖥 PAD Progression: From Healthy Highway to Total Blockage
PAD progresses from asymptomatic narrowing to claudication, rest pain, ulcers, and finally tissue death (gangrene) requiring amputation if untreated.
📋 PAD Data Collection (LPN Scope)
Intermittent claudication — Pain in the muscles from inadequate blood supply. Occurs with WALKING, relieved by REST.
Rest pain — Numbness, burning, or aching in the distal lower extremities. Awakens the client at NIGHT. Relieved by placing the extremity in a DEPENDENT position (hanging down).
Lower back or buttock discomfort
Loss of hair and dry, scaly skin on the lower extremities
Thickened toenails
Cold and gray-blue skin in the lower extremities
Elevational pallor (pale when elevated) and dependent rubor (red when hanging down)
Decreased or ABSENT peripheral pulses
Arterial ulcers — On or between the toes, or on the upper aspect of the foot. Characterized as PAINFUL.
BP measurements at the thigh, calf, and ankle are LOWER than the brachial pressure. (Normally, BP readings in the thigh and calf are HIGHER than the upper extremities.)
💊 PAD Interventions & Client Teaching
Elevate feet at rest, but NOT above heart level — extreme elevation slows arterial blood flow.
In severe cases, clients may sleep with the affected limb hanging from the bed or sit upright without leg elevation.
Monitor pain. Monitor extremities for color, motion, sensation, and pulses.
Monitor for signs of ulcer formation or gangrene.
Encourage prescribed WALKING exercise — Walk to the point of claudication, stop and rest, then walk a little farther. This develops collateral circulation (backup supply routes)!
AVOID crossing legs — interferes with blood flow.
AVOID exposure to cold (causes vasoconstriction) — wear warm socks at all times.
NEVER apply direct heat (heating pads, hot water) — decreased sensitivity causes burns!
Inspect skin daily and report any signs of breakdown.
AVOID tobacco and caffeine — vasoconstrictive effects!
Reinforce instructions about hemorheologic medications and antiplatelets as prescribed.
⚠️ Safety Alert: PAD Critical Rules
DO NOT:
❌ Apply direct heat to ischemic limbs (burns without sensation!)
❌ Elevate legs above heart level (slows arterial flow!)
❌ Cross legs (compresses arteries!)
❌ Allow smoking or caffeine (vasoconstriction!)
❌ Ignore skin breakdown (gangrene can develop rapidly!)
❄️ Raynaud's Disease: The Vasospasm Attack
Raynaud's disease is a vasospasm of the arterioles and arteries of the upper and lower extremities. The vasospasm causes constriction of the cutaneous vessels.
Triggers: Exposure to COLD or STRESS — these cause the smooth muscle cells in the arterial walls to go into spasm!
Primarily affects: Fingers, toes, ears, and cheeks.
The Three-Color Sign (Classic Triad):
⚪
1. WHITE (Blanching)
Vasospasm cuts off blood flow. Fingers turn WHITE and NUMB.
🔵
2. BLUE (Cyanosis)
Tissue becomes oxygen-deprived. Turns BLUE with tingling.
🔴
3. RED (Reperfusion)
Vasospasm releases. Blood rushes back. REDDENED and SWOLLEN.
Interventions:
Monitor pulses.
Administer vasodilators (calcium channel blockers like nifedipine inhibit vessel spasm).
Buerger's disease is an occlusive disease of the median and small arteries AND veins. The distal upper and lower limbs are affected most commonly.
KEY FACT FOR NCLEX: Buerger's disease is found primarily in YOUNG MEN who SMOKE. The cause is unknown but has an autoimmune component. Smoking cessation is the #1 treatment!
Data Collection:
Intermittent claudication (same as PAD)
Ischemic pain in the digits AT REST
Aching pain more severe at NIGHT
Cool, numb, or tingling sensation
Diminished pulses in the distal extremities
Extremities cool and RED in the dependent position
Development of ulcerations
Interventions: Same as Raynaud's disease plus SMOKING CESSATION is the most critical intervention!
🎯 NCLEX Cue Recognition: PAD vs Raynaud's vs Buerger's
When the NCLEX gives you a scenario, look for these KEY CUES:
When PAD progresses to gangrene or uncontrolled infection, amputation may be necessary. Complications include hemorrhage, infection, phantom limb pain, neuroma, and flexion contractures.
Post-Amputation Key Points:
Phantom limb pain: The client feels pain, tingling, or itching in the area where the limb WAS. This is REAL and should be medicated as prescribed. Explain this to the client!
First 24 hours: Elevate the foot of the bed to reduce edema. The residual limb is supported with pillows but NOT elevated (risk of flexion contracture).
After 24-48 hours: Position client PRONE (lying on stomach) to stretch muscles and prevent hip flexion contractures.
Do NOT elevate the residual limb on a pillow (causes hip flexion contracture!).
Maintain elastic compression wrap or stump shrinker to reduce swelling and mold the residual limb for prosthesis.
Below-knee amputation: Do not allow limb to hang over bed edge. Discourage long sitting to prevent knee flexion.
Above-knee amputation: Prevent internal/external rotation. Use sandbag or trochanter roll along the outside of the thigh.
💡 Memory Trick: Post-Amputation Positioning
"First 24: FOOT UP, not the STUMP!" — Elevate the foot of the BED (not the stump itself on pillows) to reduce edema.
"After 24: Go PRONE!" — Prone position stretches hip flexors and prevents contractures.
"Never pillow the stump!" — Placing the residual limb on a pillow causes hip flexion contracture that makes prosthesis fitting impossible!

Quiz 2: PAD & Arterial Disorders (15 Questions)
Score 80% to unlock Venous Disorders!
Q1
A client with PAD reports pain in the calf muscles when walking that is relieved by rest. The LPN documents this as:
A. Rest pain
B. Intermittent claudication
C. Phantom limb pain
D. Neuropathic pain
✅ Correct: B. Intermittent claudication is pain in the muscles resulting from inadequate blood supply during activity, relieved by rest. Rest pain (A) occurs at rest, typically at night. Cell Factory: Muscle cells need more O₂ during activity. Blocked arteries cannot deliver enough.
Q2
The LPN is reinforcing teaching to a client with PAD. Which statement by the client indicates a NEED for further teaching?
A. "I will inspect my feet daily for skin changes."
B. "I should use a heating pad on my legs when they feel cold."
C. "I need to stop smoking to improve circulation."
D. "I will avoid crossing my legs."
✅ Correct: B. NEVER apply direct heat to ischemic limbs! Decreased sensation means the client cannot feel burns. Use warm socks instead. All other statements show correct understanding.
Q3
A 24-year-old male presents with claudication in the arch of the foot and superficial thrombophlebitis. The LPN should check the client's history for:
A. Smoking history
B. Recent insect bites
C. Exposure to allergens
D. Family history of diabetes
✅ Correct: A. Young male + claudication + phlebitis (both arterial AND venous symptoms) = Buerger's disease. This is found primarily in young men who smoke. Smoking cessation is the #1 treatment. NCLEX Tip: Assess modifiable risk factors (smoking) before non-modifiable ones.
Q4
A client with Raynaud's disease asks what can be done to manage the condition. The LPN's BEST response is:
A. "You should move to a warmer climate."
B. "Eliminate caffeine and nicotine, and wear warm clothing."
C. "Elevate your hands above your head frequently."
D. "Take aspirin daily to thin your blood."
✅ Correct: B. Eliminating caffeine and nicotine (both vasoconstrictors) and wearing warm clothing are practical interventions. Moving to a warmer climate (A) is impractical and air conditioning can still trigger attacks. Calcium channel blockers like nifedipine may be prescribed to inhibit vessel spasm.
Q5
The classic color change pattern in Raynaud's disease during an attack is:
A. Red → Blue → White
B. White → Blue → Red
C. Blue → White → Red
D. White → Red → Blue
✅ Correct: B. WHITE (blanching from vasospasm) → BLUE (cyanosis from lack of oxygen) → RED (reperfusion when spasm releases and blood rushes back). Memory Trick: "WBR = White, Blue, Red" or think of the American flag colors!
Q6
Following a below-knee amputation, the LPN understands that the client should be positioned PRONE to:
A. Promote drainage from the surgical site
B. Prevent hip and knee flexion contractures
C. Reduce phantom limb pain
D. Increase blood flow to the residual limb
✅ Correct: B. Prone positioning stretches the hip flexors and prevents contractures that would make prosthesis fitting and ambulation impossible. This is typically started 24-48 hours after surgery as prescribed. LPN Action: Encourage prone positioning throughout the day as prescribed by the surgeon.
Q7
The LPN caring for a client 12 hours after above-knee amputation should AVOID which action?
A. Marking any bleeding on the dressing
B. Elevating the residual limb on two pillows
C. Explaining phantom limb sensation to the client
D. Applying the elastic compression wrap as prescribed
✅ Correct: B. Do NOT elevate the residual limb on pillows! This promotes hip flexion contracture. Instead, the foot of the BED should be elevated for the first 24 hours to reduce edema, then keep the bed flat. All other actions are appropriate.
Q8
A client with PAD is instructed about exercise. The LPN reinforces which instruction?
A. "Avoid all physical activity to prevent pain."
B. "Run until the pain becomes unbearable, then stop."
C. "Walk to the point of claudication, rest, then walk a little farther."
D. "Only exercise the upper body to avoid leg strain."
✅ Correct: C. Walking to the point of claudication, resting, and then continuing helps develop COLLATERAL CIRCULATION — backup supply routes around the blockage. This is gradually increased over time. Cell Factory: Exercise stimulates the body to grow new smaller blood vessel highways around the blocked one!
Q9
The LPN is collecting data on a client after femoral-popliteal bypass surgery. Which finding should be reported IMMEDIATELY?
A. Mild incisional pain rated 3/10
B. Cool, pale foot with absent pedal pulse
C. Temperature of 98.8°F (37.1°C)
D. Slight swelling at the incision site
✅ Correct: B. A cool, pale foot with absent pedal pulse after bypass surgery indicates GRAFT OCCLUSION — the new bypass is blocked! This is an emergency that requires immediate notification of the RN and surgeon. LPN Action: Report immediately! Monitor peripheral pulses distal to the graft every 1-2 hours postoperatively.
Q10
The most common cause of peripheral arterial disease is:
A. Venous insufficiency
B. Blood clot formation
C. Atherosclerosis
D. Vasospasm
✅ Correct: C. Atherosclerosis (plaque buildup in artery walls) is the most common cause of PAD. The same process that causes coronary artery disease also blocks peripheral arteries. Vasospasm causes Raynaud's (D). Blood clots cause DVT (B).
Q11
An arterial ulcer is MOST likely found:
A. Around the medial malleolus (inner ankle)
B. On or between the toes
C. On the posterior calf
D. On the inner thigh
✅ Correct: B. Arterial ulcers form on or between the toes or on the upper aspect of the foot — the areas farthest from the heart that receive the least blood. They are PAINFUL with a pale, deep base. Venous ulcers form around the ankles (A). NCLEX Tip: Arterial = toes/foot (far from heart). Venous = ankles (where blood pools).
Q12
The LPN notes that a client with PAD has BP readings at the ankle that are LOWER than the brachial pressure. This finding:
A. Is a normal finding
B. Indicates PAD because ankle pressures should normally be HIGHER than brachial
C. Indicates hypertension
D. Is caused by the client standing during the measurement
✅ Correct: B. Normally, BP readings in the thigh and calf are HIGHER than the upper extremities. In PAD, the arterial blockage reduces the pressure reaching the lower extremities, so ankle pressure is LOWER than brachial. This is measured by the ankle-brachial index (ABI).
Q13
The client asks about phantom limb pain after amputation. The LPN's BEST response is:
A. "The pain is not real; it's in your head."
B. "This is a real sensation that many people experience after amputation, and we can treat it with medication."
C. "This means the surgery failed."
D. "It will go away on its own within 24 hours."
✅ Correct: B. Phantom limb pain is REAL — the brain still receives signals from severed nerves. It is a common complication that can be treated with medications. Never dismiss the client's experience. LPN Action: Validate the client's feelings, medicate as prescribed, and reinforce teaching.
Q14
A client with PAD has been prescribed cilostazol. The LPN understands this medication works by:
A. Dissolving existing blood clots
B. Inhibiting platelet aggregation and dilating blood vessels
C. Lowering cholesterol levels
D. Blocking calcium channels
✅ Correct: B. Cilostazol is a platelet aggregation inhibitor and vasodilator used specifically for PAD to reduce claudication symptoms. It inhibits platelets from clumping and dilates blood vessels to improve flow. Safety: Contraindicated in heart failure!
Q15
Collateral circulation refers to:
A. Blood flowing backward through veins
B. Development of alternative blood vessel pathways around a blockage
C. Artificial grafts placed by a surgeon
D. Blood clot formation around an artery
✅ Correct: B. Collateral circulation is the body's natural development of backup supply routes around a blockage. This is why older clients may survive a blockage that would critically harm a younger person — they have had more time to develop collateral circulation. Exercise promotes this process!
When return traffic clots, valves fail, and blood pools in the legs
💧 DVT: When a Traffic Jam Becomes a Dangerous Clot
Deep Vein Thrombophlebitis (DVT) is the formation of a blood clot in a deep vein, most commonly in the legs. It is MORE SERIOUS than superficial thrombophlebitis because of the risk for PULMONARY EMBOLISM!
Cell Factory Explanation:
When blood flow slows down in the veins (stasis), the blood becomes like traffic stopped on a highway. Platelets start sticking together. Fibrin weaves around them like a net. A CLOT forms, blocking the vein and causing swelling behind it. The REAL DANGER? If the clot breaks free, it travels through the venous system → right side of the heart → LUNGS = Pulmonary Embolism!
Virchow's Triad (Three Risk Factors for Clots):
1. STASIS (slow blood flow) +
2. ENDOTHELIAL INJURY (vessel wall damage) +
3. HYPERCOAGULABILITY (blood that clots too easily) =
⚠ CLOT FORMATION (THROMBOSIS)!
⚠️ DVT Risk Factors (Know These for NCLEX!)
Venous stasis from varicose veins, heart failure, immobility
Hypercoagulability disorders
Injury to the venous wall from IV injections, vessel irritants (chemo, hypertonic solutions)
Following surgery, especially orthopedic and abdominal surgery
Pregnancy
Ulcerative colitis
Use of oral contraceptives
Certain malignancies
Fractures or injuries of the pelvis or lower extremities
Prolonged immobility (bed rest, long flights, prolonged sitting)
📋 DVT Data Collection
Calf or groin tenderness or pain with or without swelling
Positive Homans' sign may be noted — HOWEVER, false-positive results are common, so this is NOT a reliable measure!
Warm skin that is tender to touch
Unilateral leg swelling — one leg larger than the other
Redness along the affected area
💊 DVT Interventions (Critical LPN Actions!)
Bed rest as prescribed.
Elevate the affected extremity ABOVE the level of the heart as prescribed.
AVOID using the knee gatch or a pillow under the knees (compresses popliteal vein!).
DO NOT MASSAGE the extremity! Can dislodge the clot!
Apply thigh-high or knee-high antiembolism stockings as prescribed. Teach application and removal.
Apply warm, moist compresses as prescribed (check temperature before applying!).
Measure and record the circumference of BOTH thighs and calves for comparison.
Monitor for shortness of breath and chest pain — indicates PULMONARY EMBOLISM!
Administer heparin therapy as prescribed (prevents clot enlargement and new clots).
Monitor aPTT during heparin therapy (therapeutic: 1.5-2.5 times normal).
Administer warfarin as prescribed following heparin when DVT symptoms resolve.
Monitor PT/INR during warfarin therapy (therapeutic INR: 2-3).
💜 LPN Client Teaching: DVT Prevention
Avoid prolonged sitting or standing
Avoid constrictive clothing or crossing legs
Elevate legs for 10-20 minutes every few hours
Plan a progressive walking program
Inspect legs for edema, measure circumference
Wear antiembolism stockings if prescribed
Avoid smoking!
Avoid any medications unless prescribed by PHCP
Keep follow-up appointments and lab studies
Obtain and wear a MedicAlert bracelet if on anticoagulation
🔴 Varicose Veins: When the Valves Fail
Varicose veins are dilated, tortuous veins that result from incompetent valves in the veins. The vein walls weaken, dilate, and the one-way valves become unable to prevent backflow.
Data Collection:
Pain in the legs with dull aching after standing
A feeling of fullness in the legs
Ankle edema
Visible, bulging, twisted veins
Trendelenburg Test:
Place client supine with legs elevated. When client sits up, if varicosities are present, veins fill from the PROXIMAL end. (Normally, veins fill from the DISTAL end.)
Interventions:
Antiembolism stockings as prescribed
Elevate legs as much as possible
Avoid constrictive clothing and pressure on the legs
Sclerotherapy: Solution injected into vein followed by pressure dressing
Laser therapy: Laser fiber heats and closes the main vessel
Vein stripping: Removal of varicose veins >4mm diameter
🔴 Venous Insufficiency: Chronic Vein Failure
Venous insufficiency results from prolonged venous hypertension which stretches the veins and damages the valves. This causes edema, venous stasis ulcers, swelling, and cellulitis.
Data Collection:
Stasis dermatitis (brown discoloration) along the ankles extending up to the calf
Edema
Venous stasis ulcers: Uneven edges, pink ulcer bed, granulation present. Located around the ANKLES.
Interventions:
Elastic or compression stockings during the day and evening — put on WHEN AWAKENING, BEFORE getting out of bed. May need for the rest of the client's life!
Elevate legs to assist blood return to the heart
Monitor for signs of skin breakdown and infection
Wound care for venous stasis ulcers: Promote healing and prevent recurrence

Quiz 3: Venous Disorders (15 Questions)
Score 80% to unlock Pulmonary Embolism!
Q1
Which action is CONTRAINDICATED when caring for a client with DVT?
A. Applying warm moist compresses
B. Massaging the affected extremity
C. Elevating the affected leg
D. Administering heparin as prescribed
✅ Correct: B. NEVER massage a leg with DVT! This can dislodge the clot, sending it to the lungs (PE). All other options are appropriate interventions.
Q2
The LPN is monitoring a client receiving heparin for DVT. Which lab value is used to monitor heparin effectiveness?
A. PT/INR
B. aPTT
C. CBC
D. BUN/Creatinine
✅ Correct: B. Heparin = aPTT (Activated Partial Thromboplastin Time). Therapeutic range: 1.5-2.5 times normal (approximately 45-100 seconds). Warfarin = PT/INR. Memory Trick: H-eparin = H-igher aPTT. W-arfarin = W-atch the INR.
Q3
The antidote for heparin overdose is:
A. Vitamin K (phytonadione)
B. Protamine sulfate
C. Naloxone
D. Flumazenil
✅ Correct: B. Protamine sulfate is the antidote for heparin. Vitamin K (phytonadione) is the antidote for warfarin. Memory Trick: "Pro-H" = Protamine for Heparin. "K for Coumadin" = Vitamin K for warfarin (Coumadin).
Q4
A venous stasis ulcer is MOST commonly located:
A. On the toes
B. On the heel
C. Around the ankle (medial malleolus)
D. On the upper thigh
✅ Correct: C. Venous stasis ulcers form around the ankles where blood pools due to incompetent valves. They have uneven edges, pink bed, and granulation tissue. Arterial ulcers are on the toes. NCLEX Tip: Venous = Ankles. Arterial = Toes.
Q5
Antiembolism stockings for venous insufficiency should be applied:
A. After walking around for 30 minutes
B. When awakening, BEFORE getting out of bed
C. Only at bedtime
D. Only when the client has edema
✅ Correct: B. Apply stockings when awakening, BEFORE getting out of bed, while the legs are least swollen. Walking causes blood to pool in the legs, making the stockings harder to apply and less effective.
Q6
The LPN understands that DVT is more dangerous than superficial thrombophlebitis because of the risk for:
A. Gangrene
B. Pulmonary embolism
C. Arterial occlusion
D. Varicose veins
✅ Correct: B. DVT carries the risk of clot breaking free and traveling to the lungs (pulmonary embolism), which can be life-threatening. Superficial clots rarely embolize.
Q7
Which is a risk factor for DVT development? Select ALL that apply.
A. Prolonged immobility
B. Regular exercise
C. Recent orthopedic surgery
D. Use of oral contraceptives
E. Pregnancy
✅ Correct: A, C, D, E. All increase DVT risk. Immobility causes stasis. Surgery causes endothelial injury. Oral contraceptives and pregnancy increase hypercoagulability. Regular exercise (B) REDUCES risk by promoting blood flow.
Q8
The Trendelenburg test is used to evaluate:
A. Arterial blood flow
B. Varicose veins
C. Deep vein thrombosis
D. Pulmonary embolism
✅ Correct: B. The Trendelenburg test evaluates varicose veins. Place client supine with legs elevated, then have them sit up. If varicosities are present, veins fill from the PROXIMAL end (abnormal). Normally, veins fill from the distal end.
Q9
The LPN is administering subcutaneous heparin. Which technique is CORRECT?
A. Inject in the deltoid muscle and massage after injection
B. Inject in the abdomen at 90 degrees; do NOT aspirate or rub the site
C. Inject in the thigh and apply ice after
D. Inject in the arm and apply pressure for 10 minutes
✅ Correct: B. Subcutaneous heparin is injected into the abdomen with a 5/8-inch needle (25-28 gauge) at 90 degrees. Do NOT aspirate, rub, or massage the site — this causes bruising and hematoma. LPN Safety: Rotate injection sites within the abdominal area.
Q10
A client on warfarin has an INR of 4.5. The LPN should:
A. Administer the next dose as scheduled
B. Hold the medication and notify the RN/PHCP immediately
C. Increase the dose
D. Give vitamin K without an order
✅ Correct: B. Therapeutic INR for standard warfarin therapy is 2-3. An INR of 4.5 is dangerously elevated — high risk for bleeding! Hold the medication and notify immediately. Initiate bleeding precautions. Vitamin K may be prescribed by the PHCP. LPN Action: Hold, report, and implement bleeding precautions!
Q11
The LPN monitors a client on heparin for signs of bleeding. Which finding should be reported?
A. Bruising on the abdomen at injection sites only
B. Bleeding gums, hematuria, and petechiae
C. Mild headache
D. Slight redness at the IV site
✅ Correct: B. Bleeding gums, blood in the urine (hematuria), nosebleeds, ecchymosis, and petechiae are all signs of excessive anticoagulation and must be reported immediately. These indicate the drug is working TOO well — the patient is at risk for hemorrhage!
Q12
A client on warfarin asks about diet. The LPN reinforces which instruction?
A. "Eat as many green leafy vegetables as you want."
B. "Eat a CONSISTENT amount of green leafy vegetables each day."
C. "Avoid all green leafy vegetables completely."
D. "Green vegetables have no effect on warfarin."
✅ Correct: B. Green leafy vegetables contain Vitamin K, which COUNTERACTS warfarin. The key is CONSISTENCY — eat about the same amount each day so the warfarin dose stays effective. Sudden increases in Vitamin K intake will decrease warfarin's effect. Sudden decreases will increase bleeding risk.
Q13
The D-dimer blood test is used to help diagnose:
A. Heart failure
B. DVT and pulmonary embolism
C. Atherosclerosis
D. Raynaud's disease
✅ Correct: B. D-dimer measures fibrin degradation products (breakdown of a blood clot). A normal D-dimer (≤250 ng/mL) makes DVT/PE very unlikely. An elevated D-dimer suggests a clot is present, but it is not diagnostic alone — further imaging is needed.
Q14
The therapeutic aPTT range for a client receiving continuous IV heparin is:
A. 10-20 seconds
B. 30-40 seconds
C. 1.5 to 2.5 times the normal value
D. 200-300 seconds
✅ Correct: C. The therapeutic aPTT is 1.5 to 2.5 times the normal value (normal is 30-40 seconds). So therapeutic range is approximately 45-100 seconds. Option B is the NORMAL range, not the therapeutic range during heparin therapy.
Q15
A client with DVT asks why they cannot get out of bed. The LPN's BEST response is:
A. "You need to rest so the medications can work faster."
B. "Activity could cause the blood clot to break free and travel to your lungs, which is life-threatening."
C. "Walking would cause another clot to form."
D. "Your doctor just prefers bed rest for all patients."
✅ Correct: B. Honest, factual explanation helps the client understand the seriousness of the situation. Activity can dislodge the clot, causing a pulmonary embolism. Bed rest with leg elevation is prescribed to reduce this risk.
When a clot travels to the lungs — Recognize it. Report it. SAVE A LIFE.
⚠️ Pulmonary Embolism: The Deadliest Complication of DVT
A pulmonary embolism (PE) occurs when a thrombus (most commonly from a deep vein in the leg) detaches, travels to the RIGHT side of the heart, and lodges in a branch of the pulmonary artery, blocking blood flow to the lungs.
THIS IS A MEDICAL EMERGENCY! IT CAN BE FATAL!
At-Risk Clients:
Those at risk for DVT: prolonged immobilization, surgery, obesity
Pregnancy, heart failure, advanced age
History of thromboembolism
Fat emboli from long bone fractures can also cause PE!
🚨 RECOGNIZE THESE CUES: Pulmonary Embolism Signs & Symptoms
NCLEX Strategy: When a question describes a post-surgical or immobilized client who suddenly develops chest pain and shortness of breath, the answer is almost always PULMONARY EMBOLISM. Do not confuse with MI (which has different risk factors and presentation).
📝
Quiz 4: Pulmonary Embolism (15 Questions)
Score 80% to unlock Aortic Aneurysms!
Q1
A client 1 day post hip surgery suddenly develops chest pain, dyspnea, and tachycardia. The LPN suspects:
A. Pneumonia
B. Pulmonary embolism
C. Myocardial infarction
D. Anxiety attack
✅ Correct: B. Post-surgical client + sudden chest pain + dyspnea + tachycardia = classic PE presentation. The client is at high risk due to surgery and immobility. LPN Action: Notify Rapid Response Team IMMEDIATELY!
Q2
The FIRST action by the LPN when PE is suspected is:
A. Administer oxygen
B. Notify the RN and Rapid Response Team
C. Obtain an ABG
D. Place the client flat in bed
✅ Correct: B. PE is life-threatening and requires immediate notification. While the team responds, elevate HOB, reassure client, and prepare to administer oxygen. Do NOT lay the client flat — elevate the head of the bed to ease breathing.
Q3
A normal D-dimer level is:
A. 500 ng/mL or less
B. 250 ng/mL or less
C. 1000 ng/mL or less
D. 100 ng/mL or less
✅ Correct: B. D-dimer values of 250 ng/mL or less are normal. A normal D-dimer makes PE very unlikely. An elevated D-dimer is NOT diagnostic by itself — CT pulmonary angiography is needed for confirmation.
Q4
The PREFERRED diagnostic test for confirming pulmonary embolism is:
A. Chest X-ray
B. Electrocardiogram
C. CT pulmonary angiography (CTPA)
D. D-dimer blood test
✅ Correct: C. CTPA is the preferred method — it uses contrast dye to visualize blood clots in the pulmonary arteries. D-dimer is a screening test, not diagnostic. A V/Q scan is used if CTPA is contraindicated.
Q5
Which client is at HIGHEST risk for developing a pulmonary embolism?
A. A 25-year-old who jogs daily
B. A 72-year-old on bed rest after hip replacement surgery
C. A 30-year-old with a mild cold
D. A 45-year-old office worker who walks 30 minutes daily
✅ Correct: B. Advanced age + surgery + immobilization = highest risk. These match all three parts of Virchow's Triad: stasis (immobility), endothelial injury (surgery), and hypercoagulability (post-surgical state).
Q6
The client with suspected PE should be positioned:
A. Flat in bed (supine)
B. Trendelenburg position
C. With the head of bed ELEVATED
D. Prone position
✅ Correct: C. Elevate the head of the bed to ease breathing and reduce oxygen demand. Do NOT lay the client flat or place in Trendelenburg — this increases the work of breathing and may worsen the situation.
Q7
Blood-tinged sputum in a client with suspected PE is caused by:
A. Lung tissue damage from the blocked artery
B. Bronchitis
C. Gastric bleeding
D. Medication side effect
✅ Correct: A. When the pulmonary artery is blocked, the lung tissue beyond the blockage becomes ischemic and damaged, leading to blood-tinged sputum (hemoptysis). This is a classic sign of PE.
Q8
Fat embolism is a potential complication of:
A. Myocardial infarction
B. Long bone fractures
C. Pneumonia
D. Liver failure
✅ Correct: B. Fat emboli can occur after fractures of long bones (femur, tibia). Fat globules from the bone marrow enter the bloodstream and can travel to the lungs, causing pulmonary emboli. NCLEX Cue: Post-fracture client + sudden respiratory distress + petechiae over chest = think fat embolism!
Q9
The LPN is caring for a client with DVT who suddenly complains of chest pain and anxiety. Which finding BEST confirms the LPN's suspicion of PE?
A. Temperature of 100.2°F
B. BP 160/90 mmHg
C. Sudden dyspnea with tachycardia and tachypnea
D. Leg edema slightly increased
✅ Correct: C. The hallmark triad of PE is sudden dyspnea + chest pain + tachycardia/tachypnea. Combined with a history of DVT and chest pain/anxiety, this strongly suggests PE. Elevated temperature and leg edema are expected DVT findings.
Q10
The MOST important preventive measure for PE is:
A. Administering aspirin to all post-surgical clients
B. Early ambulation and DVT prevention measures
C. Keeping all clients on bed rest after surgery
D. Giving warfarin to all hospitalized clients
✅ Correct: B. Prevention is key! Early ambulation, leg exercises, antiembolism stockings, sequential compression devices, and prophylactic anticoagulation as prescribed are the best measures to prevent DVT and subsequent PE.
Q11
A client diagnosed with DVT 1 day ago suddenly has chest pain and shortness of breath. The LIFE-THREATENING complication the LPN should suspect is:
A. Pneumonia
B. Pulmonary edema
C. Pulmonary embolism
D. Myocardial infarction
✅ Correct: C. DVT client + sudden chest pain + SOB = pulmonary embolism until proven otherwise. MI and pulmonary edema are cardiac problems. Pneumonia is an infectious process. The DVT history makes PE the most likely cause.
Q12
Which breath sounds would the LPN expect to hear in a client with PE?
A. Stridor
B. Crackles and wheezes
C. Rhonchi
D. Bronchial breath sounds
✅ Correct: B. Crackles and wheezes during auscultation are associated with PE. The blocked blood flow causes fluid to leak into the lung tissue (crackles) and bronchospasm (wheezes).
Q13
Fill in the blank: Pulmonary embolism occurs when a thrombus from a deep vein detaches and travels to the ______________ side of the heart, then lodges in the ______________ artery.
✅ Answer: RIGHT side of the heart, PULMONARY artery. Venous blood returns to the RIGHT atrium → RIGHT ventricle → pulmonary artery. The clot follows the flow of blood from the veins to the right heart to the lungs. It CANNOT go to the left side because blood flows RIGHT → lungs → LEFT.
Q14
The medication initially prescribed for PE treatment is typically:
A. Warfarin
B. Aspirin
C. Heparin
D. Clopidogrel
✅ Correct: C. Heparin is used first because it works IMMEDIATELY to prevent clot extension. Warfarin takes 3-5 days to reach therapeutic effect. The client may receive both (bridge therapy) until the INR is therapeutic, then heparin is discontinued.
Q15
Petechiae over the chest and axilla in a client with a recent long bone fracture suggests:
A. Allergic reaction
B. Fat embolism
C. Heparin-induced thrombocytopenia
D. Vitamin K deficiency
✅ Correct: B. Petechiae over the chest and axilla is a CLASSIC sign of fat embolism. Fat globules from the fractured bone marrow damage capillary walls, causing petechiae. Combined with respiratory distress, this confirms fat embolism syndrome.

Section 5: Aortic Aneurysms — When the Highway Walls Balloon
Understanding types, recognition, and emergency management
💣 Aortic Aneurysm: The Bulging Highway Wall
An aortic aneurysm is an abnormal dilation of the arterial wall caused by localized weakness and stretching in the medial layer (tunica media) of the aorta.
Cell Factory Explanation: The smooth muscle cells and elastic fibers in the tunica media are the wall's "structural support beams." When these get damaged by atherosclerosis, hypertension, or connective tissue disorders, the wall weakens. Blood pressure pushes against the weak spot, causing it to balloon outward — like a weak spot on a tire!
Goal of treatment: Limit progression, control BP, recognize symptoms early, and PREVENT RUPTURE!
🔬 Four Types of Aortic Aneurysm
🔬 Types of Aortic Aneurysm
Fusiform
Diffuse dilation involving the ENTIRE circumference of the arterial segment. Like a sausage-shaped bulge.
Saccular
Distinct localized outpouching of the artery wall. Like a balloon poking out from one side.
Dissecting
Blood separates the layers of the artery wall, forming a cavity between them. EXTREMELY dangerous!
False (Pseudoaneurysm)
Clot and connective tissue OUTSIDE the arterial wall. Occurs from vessel injury or trauma to all three layers.
📋 Data Collection by Location
Thoracic Aneurysm:
Pain extending to neck, shoulders, lower back, or abdomen
Syncope (fainting)
Dyspnea (difficulty breathing — aneurysm pressing on airways)
Increased pulse, cyanosis, weakness
Hoarseness or difficulty swallowing (pressure from aneurysm on esophagus/trachea)
Abdominal Aneurysm:
Prominent, PULSATING mass in the abdomen, at or above the umbilicus
Systolic bruit over the aorta (whooshing sound heard with stethoscope)
Tenderness on deep palpation
Abdominal or lower back pain
🚨 DANGER: Signs of RUPTURING Aneurysm!
Severe abdominal or back pain!
Lumbar pain radiating to the flank and groin
Hypotension and increased pulse rate
Signs of SHOCK (cool, clammy skin, altered consciousness)
❌ AVOID PALPATING the abdomen if an abdominal aneurysm is suspected!
💊 Aneurysm Interventions
Nonsurgical Management:
Modify risk factors (smoking cessation, BP control, cholesterol management)
Antihypertensives to maintain BP within normal limits and prevent strain
Regular PHCP visits to monitor aneurysm size
Client teaching: Report IMMEDIATELY: severe back/abdominal pain, fullness, soreness over umbilicus, sudden discoloration in extremities, persistent BP elevation
Monitor for graft occlusion: changes in pulses, cool/cold/white/blue extremities, severe pain, abdominal distention
Limit HOB elevation to 45 degrees to prevent flexion of graft
Monitor for hypovolemia and kidney failure (significant blood loss during surgery)
Monitor urine output hourly — notify PHCP if <30 mL/hr
No lifting >15-20 lb for 6-12 weeks
Avoid pushing, pulling, straining
No driving until approved by PHCP
💜 LPN Scope: Aneurysm Care
Monitor vital signs closely, especially blood pressure
DO NOT palpate the abdomen if aneurysm is suspected
Report immediately: severe pain, hypotension, tachycardia, signs of shock
Post-op: Check peripheral pulses distal to graft EVERY hour initially
Monitor urine output: Report <30 mL/hr
Reinforce teaching: Avoid lifting, straining, report any new symptoms

Score 80% to unlock Medications!
Q1
A client with an abdominal aortic aneurysm suddenly complains of severe back pain. The LPN should FIRST:
A. Administer prescribed pain medication
B. Contact the RN and PHCP immediately — suspect rupture
C. Reposition the client for comfort
D. Apply heat to the back for pain relief
✅ Correct: B. Severe back pain in a client with an aortic aneurysm = suspect RUPTURE, which is a surgical emergency! Notify RN and PHCP immediately.
Q2
The LPN should AVOID which action when caring for a client with a suspected abdominal aortic aneurysm?
A. Monitoring vital signs
B. Palpating the abdomen
C. Auscultating for a bruit
D. Monitoring peripheral pulses
✅ Correct: B. AVOID palpating the abdomen if an abdominal aneurysm is suspected! Palpation could cause RUPTURE.

After abdominal aortic aneurysm repair, the LPN monitors urine output. Which finding requires immediate notification?
A. Urine output of 50 mL/hour
B. Urine output of 20 mL/hour
C. Clear, yellow urine
D. Urine output of 40 mL/hour
✅ Correct: B. Urine output less than 30 mL/hour indicates possible kidney failure from blood loss during surgery. Report immediately!
Q4
An aortic aneurysm is caused by weakness in which layer of the arterial wall?
A. Tunica intima (inner lining)
B. Tunica media (middle muscle layer)
C. Tunica adventitia (outer layer)
D. Endothelium only
✅ Correct: B. The tunica media is the muscular, elastic middle layer. Cell Factory: The smooth muscle cell factories in the media are the "structural beams" — when they fail, the wall collapses outward.
Q5
A pulsating abdominal mass with a systolic bruit is a characteristic finding of:
A. Peptic ulcer disease
B. Abdominal aortic aneurysm
C. Appendicitis
D. Pancreatitis
✅ Correct: B. A prominent, pulsating mass at or above the umbilicus with a systolic bruit is the classic presentation of abdominal aortic aneurysm.

Section 6: Vascular Medications & Anticoagulation
Anticoagulants, thrombolytics, antiplatelets, and vasodilators
💊 The Clotting Cascade & Drug Targets
Understanding WHERE drugs work on the clotting cascade is KEY for NCLEX! Think of clotting as an assembly line in a factory. Different drugs shut down different parts of the assembly line.
Cell Factory: Platelets are the "first responders" that form a plug. Clotting factors (made by liver hepatocyte factories) weave fibrin to make the plug permanent. Each drug class targets a different part of this factory assembly line!
Cold, pale legs with absent pulses and pain during walking indicate:
A. DVT
B. PAD
C. Venous insufficiency
D. Varicose veins
✅ Correct: B. Cold + pale + absent pulses + claudication = ARTERIAL disease (PAD).
Q3
Protamine sulfate is the antidote for:
A. Warfarin
B. Aspirin
C. Heparin
D. Clopidogrel
✅ Correct: C. Protamine sulfate for heparin. Vitamin K for warfarin. "Pro-H" memory trick.
Q4
The LPN should AVOID palpating the abdomen of a client with a suspected:
A. Peptic ulcer
B. Abdominal aortic aneurysm
C. Cholecystitis
D. Appendicitis
✅ Correct: B. NEVER palpate an abdomen when an aortic aneurysm is suspected. Palpation can cause RUPTURE!
Q5
A client with DVT should have the affected leg positioned:
A. Flat on the bed
B. Elevated ABOVE the level of the heart
C. In a dependent position
D. On a pillow under the knee
✅ Correct: B. Elevate ABOVE heart level to promote venous return and reduce swelling. AVOID knee gatch or pillow under the knee.
Q6
The classic triad of signs for Raynaud's disease is:
A. Redness, warmth, swelling
B. White, blue, red color changes in fingers/toes
C. Pain, pallor, pulselessness
D. Edema, brown discoloration, ulcers
✅ Correct: B. Raynaud's: WHITE (vasospasm) → BLUE (cyanosis) → RED (reperfusion). Triggered by cold or stress.
Q7
For the first 24 hours after a below-knee amputation, the stump should be:
A. Elevated on pillows
B. Elevated by raising the FOOT of the bed
C. Placed in a prone position
D. Kept at heart level
✅ Correct: B. First 24 hours: elevate by raising the FOOT of the bed (NOT pillows!). After 24-48 hours: go PRONE to prevent hip flexion contracture.
Q8
The therapeutic INR range for standard warfarin therapy is:
A. 0.5-1.0
B. 2-3
C. 4-5
D. 6-8
✅ Correct: B. Therapeutic INR is 2-3. Above 3 = increased bleeding risk. Above 5 = dangerous!
Q9
Intermittent claudication is BEST described as:
A. Chest pain during exertion
B. Cramping leg pain during walking that is relieved by rest
C. Constant burning pain in the legs
D. Pain only when lying flat
✅ Correct: B. Claudication = cramping pain during activity, relieved by rest. Muscles demand more O2 during activity, but narrowed arteries can't deliver enough.
Q10
Virchow's Triad includes all EXCEPT:
A. Venous stasis
B. Hypercoagulability
C. Endothelial injury
D. Hypertension
✅ Correct: D. Virchow's Triad: STASIS + ENDOTHELIAL INJURY + HYPERCOAGULABILITY = clot formation. Hypertension is a risk factor for aneurysm, not part of Virchow's Triad.
Q11
Fill in the blank: Arterial disease causes legs that are _______ and _______, while venous disease causes legs that are _______ and _______.
✅ Answer: Arterial = COLD and PALE. Venous = WARM and EDEMATOUS (swollen). Remember: Arterial = absence of blood (cold, pale, no pulse). Venous = too much blood pooling (warm, swollen, discolored).
Q12
The most reliable diagnostic sign of DVT is:
A. Positive Homans' sign
B. Unilateral leg swelling with tenderness
C. Bilateral leg edema
D. Cool, pale extremity
✅ Correct: B. Unilateral (one-sided) leg swelling with warmth and tenderness is the most reliable clinical finding. Homans' sign is UNRELIABLE (many false positives). Cool/pale = arterial disease.
Q13
A client with PAD should be instructed to:
A. Elevate legs above the heart
B. Walk until claudication occurs, then rest and resume
C. Apply heating pads directly to the legs
D. Cross legs when sitting
✅ Correct: B. Progressive walking (to claudication point, rest, resume) builds collateral circulation. DO NOT elevate above heart (reduces arterial flow). NO heating pads (burn risk!). NO crossing legs.
Q14
Buerger's disease (thromboangiitis obliterans) is MOST commonly seen in:
A. Elderly women with diabetes
B. Young male smokers
C. Children with congenital defects
D. Pregnant women
✅ Correct: B. Buerger's disease is strongly associated with cigarette smoking in young males (20-40 years). It causes both arterial AND venous symptoms. MUST stop smoking!
Q15
Brown discoloration along the ankles extending up the calf is characteristic of:
A. PAD
B. DVT
C. Venous insufficiency (stasis dermatitis)
D. Raynaud's disease
✅ Correct: C. Brown discoloration = stasis dermatitis from chronic venous insufficiency. Hemosiderin deposits from RBC breakdown cause the brown color.
Q16
Petechiae over the chest and axilla in a client with a recent femur fracture suggests:
A. Allergic reaction
B. Fat embolism
C. Heparin reaction
D. Platelet disorder
✅ Correct: B. Post long bone fracture + petechiae over chest/axilla + respiratory distress = FAT EMBOLISM. Fat globules from bone marrow damage capillaries.
Q17
The 6 P's of neurovascular compromise include all EXCEPT:
A. Pain and Pallor
B. Pulselessness and Paresthesia
C. Paralysis and Poikilothermia
D. Palpitations and Perspiration
✅ Correct: D. The 6 P's are: Pain, Pallor, Pulselessness, Paresthesia, Paralysis, and Poikilothermia (cool temperature). Palpitations and perspiration are not part of the 6 P's.
Q18
A client taking warfarin asks about eating salads. The BEST instruction is:
A. "Avoid all salads."
B. "Eat a CONSISTENT amount of green leafy vegetables each day."
C. "Eat as much as you want."
D. "Salads have no effect on warfarin."
✅ Correct: B. CONSISTENCY is key! Green leafy vegetables contain Vitamin K, which counteracts warfarin. Don't avoid them — just keep intake consistent.
Q19
After aortic aneurysm graft repair, cold/pale extremities distal to the graft with absent pulses indicate:
A. Normal post-operative finding
B. Graft occlusion — notify PHCP immediately
C. Venous insufficiency
D. Raynaud's disease
✅ Correct: B. Cool/cold/white/blue extremities + absent pulses distal to graft = GRAFT OCCLUSION. This is a surgical emergency! Notify immediately.
Q20
Antiembolism stockings should be applied:
A. After walking for 30 minutes
B. When awakening, BEFORE getting out of bed
C. Only at bedtime
D. When edema is at its worst
✅ Correct: B. Apply BEFORE getting out of bed, when legs are least swollen, for best compression effectiveness.
Q21
A client with suspected PE should be positioned with:
A. Head of bed flat
B. Head of bed ELEVATED
C. Trendelenburg position
D. Left lateral recumbent
✅ Correct: B. Elevate HOB to ease breathing and reduce oxygen demand. NEVER flat or Trendelenburg for PE.
Q22
The LPN is caring for a client receiving alteplase (tPA) for massive PE. Which action is MOST important?
A. Monitor for signs of bleeding at ALL sites
