The nurse is assigned to care for a client who is 2 days postoperative after an above-the-knee amputation of the right leg. The nurse plans to implement which measure to prevent hip contractures?

Correct Answer: D. Position the client on the abdomen for 20 to 30 minutes twice a day.

Rationale: Positioning the client on the abdomen helps prevent hip contractures by stretching the hip flexors and maintaining hip extension. This position also helps to prevent hip adduction contractures, which can occur due to prolonged positioning on the back. By alternating positions, the client's hip joint is kept in a more functional and extended position, reducing the risk of contractures.

Summary of other choices:
A: Maintaining the client in a supine position does not actively prevent hip contractures and may even contribute to hip flexion contractures.
B: Maintaining a high-Fowler's position when the client is in bed does not address hip extension and may lead to hip flexion contractures.
C: Elevating the stump on a pillow is important for stump care but does not specifically target prevention of hip contractures.
