The nurse identifies the nursing diagnosis for a client as ineffective peripheral tissue perfusion related to decreased arterial flow to extremities
Which of the following measures should the nurse instruct the client to do to improve blood flow? 1. Cross the legs at the knees when seated.
2. Elevate the feet while reclining.
3. Position with the extremities dependent.
4. Use a heating pad to increase warmth.
3. Position with extremities dependent.
Rationale:
Positioning with the extremities dependent is correct because gravity promotes arterial flow to the dependent extremity, increasing tissue perfusion. Crossing the legs at the knees when seated is not recommended because this position compresses partially obstructed arteries and impairs blood flow. Elevating the feet while reclining is not recommended because elevating the feet works against gravity and will further impede blood flow. Using a heating pad to increase warmth is not recommended because external heating devices could increase the risk of burns in a client with impaired circulation and the consequent decreased sensation.
