136) Answer

A. Reduces the risk of DVTs

Rationale

•DVTs are prevented with the use of anticoagulation, compression stockings, sequential compression devices, and exercise. Having the head of bed at 15 to 30 degrees will not signigicantly affect the risk of DVTs.

•A patient with an increased intracranial pressure should have their bed elevated to 15-30 degrees. This will help increase venous outflow, which decreases ICP. Elevating the head too much can decrease cerebral perfusion pressure, causes hypoxia and ischemia.
