Question 2 of 5
The nurse is preparing to boost a client up in bed. She instructs the client to use the overbed trapeze. Which risk factor for pressure ulcer development is the nurse reducing by instructing the client to move in this manner?
Correct Answer: D
Rationale: Using a trapeze reduces shearing forces (opposing forces that cause layers of skin to move over each other, stretching and tearing capillaries and, eventually, resulting in necrosis), which increase the risk of pressure ulcer development. They can occur as clients slide down in bed or when they're pulled up in bed.
To reduce shearing forces, the nurse should instruct the client to use an overbed trapeze, place a draw sheet under the client to move the client up in bed, and keep the head of the bed no higher than 30 degrees. The risks of friction, impaired circulation, and localized pressure aren't decreased with trapeze use.
