📒 The 1-minute cheat sheet
🩺 Signs
Intermittent claudication
Cool, pale, hairless, shiny skin
↓ pulses, pain worse w/ elevation
Pain relieved by dangling
✅ Do
Dangle legs, keep warm
Walk to tolerance, foot care
📌 Avoid
No leg elevation
No smoking, no crossing legs
No tight clothing/cold
🚩 Report
Critical ischemia → gangrene
📚 Peripheral Arterial Disease — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Peripheral arterial disease is narrowing of the arteries in the limbs, usually from atherosclerosis, that reduces blood flow to the extremities. The reduced arterial supply causes pain with activity (intermittent claudication), cool pale limbs, and poor wound healing. The key contrast for the exam is arterial versus venous insufficiency: arterial problems mean tissue is not getting enough oxygenated blood.
🔑
Key points
Understand these first
Intermittent claudication is cramping leg pain with walking that is relieved by rest.
Affected limbs are cool, pale, shiny, and hairless with diminished or absent pulses and thick toenails.
Pain worsens with elevation and improves with dependent (dangling) positioning because gravity aids arterial flow.
Arterial ulcers are painful, round, and on the toes or pressure points with little drainage.
Major risk factors are smoking, diabetes, hypertension, and high cholesterol.
✅
Nursing priorities
What to do, in order
Assess and document peripheral pulses, skin color, temperature, capillary refill, and pain.
Position the legs in a dependent or neutral position rather than elevated to promote arterial flow.
Encourage a gradual walking program to promote collateral circulation as tolerated.
Promote smoking cessation and protect the extremities from injury and temperature extremes.
Administer antiplatelet medications and manage diabetes, hypertension, and cholesterol as ordered.
🚩
Red flags — report now
Escalate immediately
Sudden severe leg pain with pallor, pulselessness, coldness, and numbness signals acute arterial occlusion and is a limb-threatening emergency.
A new non-healing ulcer or signs of gangrene must be reported immediately.
Loss of a previously present pulse requires immediate provider notification.
🧪
Labs & values
Numbers to know
Ankle-brachial index (ABI): normal 0.9-1.3; below 0.9 indicates PAD
Lipid panel: LDL goal less than 100 mg/dL
Hemoglobin A1c to assess diabetes control
🗣️
Patient teaching
What patients must know
Stop smoking completely, as nicotine constricts arteries and worsens the disease.
Inspect the feet daily, wear well-fitting shoes, avoid going barefoot, and protect the legs from heat, cold, and injury.
Walk regularly to the point of pain then rest, keep the legs in a dependent position, and avoid crossing the legs or tight clothing.
❓ Peripheral Arterial Disease: NCLEX FAQs
What are the priority nursing interventions for Peripheral Arterial Disease?
Assess and document peripheral pulses, skin color, temperature, capillary refill, and pain. Position the legs in a dependent or neutral position rather than elevated to promote arterial flow. Encourage a gradual walking program to promote collateral circulation as tolerated. Promote smoking cessation and protect the extremities from injury and temperature extremes.
What are the warning signs of Peripheral Arterial Disease a nurse must report?
Sudden severe leg pain with pallor, pulselessness, coldness, and numbness signals acute arterial occlusion and is a limb-threatening emergency. A new non-healing ulcer or signs of gangrene must be reported immediately. Loss of a previously present pulse requires immediate provider notification.
