A nurse is providing discharge teaching to an older adult client following a left total hip arthroplasty. Which of the following instructions should the nurse include in the teaching?

Rationale: A. "Install a raised toilet seat in your bathroom.": A raised toilet seat helps maintain proper hip alignment and prevents excessive hip flexion, which can reduce the risk of dislocation after a total hip arthroplasty. This modification allows the client to sit and stand safely while protecting the surgical site during activities of daily living. B. "Clean the incision daily with hydrogen peroxide.": Using hydrogen peroxide on a healing incision can damage tissue and delay wound healing. The recommended practice is to clean the incision gently with mild soap and water and keep it dry, following the provider’s instructions. C. "You can cross your legs at the ankles when sitting down.": Crossing the legs, even at the ankles, can place the hip in adduction or internal rotation, increasing the risk of prosthetic dislocation. Clients are advised to avoid crossing legs and to maintain neutral hip positioning. D. "You should use an incentive spirometer every 8 hours.": Incentive spirometry is recommended more frequently, usually every 1–2 hours while awake, to prevent postoperative pulmonary complications. Using it only every 8 hours would be insufficient for optimal lung expansion and airway clearance.
