A client with a history of peripheral artery disease (PAD) reports sudden severe pain, numbness, and coolness in their right leg. What is the most appropriate action for the client to take?
Apply a heating pad to the affected leg
Elevate the leg above heart level
Rest and avoid moving the leg
Perform gentle leg exercises
The Correct Answer is C
A. Applying a heating pad is not appropriate because clients with PAD have reduced circulation, increasing the risk of burns due to impaired sensation.
B. Elevating the leg above heart level can further reduce arterial blood flow, worsening ischemia.
C. Resting and avoiding movement is the best action, as sudden severe pain, numbness, and coolness suggest acute arterial occlusion, a medical emergency requiring immediate evaluation to prevent limb loss.
D. Performing gentle leg exercises is not advisable, as movement could further compromise circulation in an acutely ischemic limb.

Correct Answer is B
Explanation
A) Incorrect - Encouraging early ambulation and leg exercises is essential after peripheral artery bypass surgery to promote blood circulation and prevent complications like deep vein thrombosis.
B) Correct - Elevating the affected leg above heart level while resting can help reduce swelling and promote blood flow, aiding in the healing process after peripheral artery bypass surgery.
C) Incorrect - Applying direct pressure to the surgical incision if it starts bleeding may worsen the bleeding. Instead, the client should apply gentle pressure with a clean cloth and seek immediate medical attention if bleeding does not stop.
D) Incorrect - Taking hot baths is not recommended after peripheral artery bypass surgery. Heat may dilate blood vessels and increase blood flow, potentially causing complications at the surgical site.
Correct Answer is C
Explanation
A) Incorrect - Angiography is a diagnostic test used to visualize blood vessels after the injection of a contrast medium. While it can assess blood flow, it is not the most common test for PVD.
B) Incorrect - An electrocardiogram (ECG) is used to assess the electrical activity of the heart and is not specific to PVD or lower extremity blood flow.
C) Correct - The ankle-brachial index (ABI) is the most commonly used test to assess blood flow in the lower extremities for PVD. It compares blood pressure measurements at the ankle and arm to determine peripheral artery occlusive disease.
D) Incorrect - A lumbar puncture is not used to assess blood flow in the lower extremities. It is a procedure for obtaining cerebrospinal fluid for diagnostic purposes in certain neurological conditions.
