A nurse is reinforcing teaching with a client who is 24 hours postoperative following a total hip arthroplasty. Which of the following instructions should the nurse include in the teaching?

Apply moist heat to the incision while in bed.

Sit in a straight-backed chair.

Perform range of motion exercises by adducting the hip.

Answer and Explanation

The Correct Answer is B

Sit in a straight-backed chair. After a total hip arthroplasty, the client should avoid sitting in chairs that are too low or too soft, as they can be difficult to rise from and can risk dislocating the new hip. The client should apply ice to the incision site, not moist heat, in the first few days postoperatively. The client should avoid adducting the hip as this can also risk dislocation of the new hip joint. Hydrogen peroxide should not be used to clean the surgical incision, as it can delay wound healing.

Choice A: The client should apply ice to the incision site, not moist heat, in the first few days postoperatively.

Choice C: The client should avoid adducting the hip as this can risk dislocation of the new hip joint.
