Patient Care第 34 / 100 题
Before ambulating a patient who has been on bed rest, the technician has the patient sit on the edge of the bed and dangle the legs for a few minutes. What is the main purpose of dangling?
a.To allow the body to adjust and prevent dizziness from orthostatic hypotension
b.To measure the patient's height
c.To warm the patient's feet
d.To count the respiratory rate
解析
Dangling lets the patient sit upright with the legs over the side of the bed so the cardiovascular system can adjust to the upright position. This helps prevent orthostatic hypotension and dizziness that can cause a fall. The technician assesses for lightheadedness before assisting the patient to stand.
