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?

A. "You can cross your legs at the ankles when sitting down.": Crossing legs, even at the ankles, can increase the risk of hip dislocation following total hip arthroplasty. Clients should avoid crossing legs to maintain proper joint alignment and prevent complications. B. "Clean the incision daily with hydrogen peroxide.": Hydrogen peroxide can damage healing tissue and delay wound healing. The incision should be cleaned gently with mild soap and water or as instructed by the surgeon to prevent infection without harming tissue. C. "You should use an incentive spirometer every 8 hours.": Incentive spirometry is typically recommended more frequently, usually 10 times per hour while awake, to prevent postoperative pulmonary complications. Every 8 hours would be insufficient for effective lung expansion. D. "Install a raised toilet seat in your bathroom.": A raised toilet seat helps the client maintain hip precautions by reducing hip flexion beyond 90 degrees, decreasing the risk of dislocation. This is an important safety modification for home care following hip arthroplasty.
