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. "You should use an incentive spirometer every 8 hours." Using an incentive spirometer is important for preventing respiratory complications, but the recommendation should be to use it every 1-2 hours while awake, not just every 8 hours. B. "Clean the incision daily with hydrogen peroxide." Hydrogen peroxide is too harsh for wound care and can delay healing by damaging new tissue. The incision should be cleaned with mild soap and water or as directed by the healthcare provider. C. "You can cross your legs at the ankles when sitting down." After a hip replacement, clients should avoid crossing their legs, especially at the knees, to prevent dislocation of the new hip joint. D. "Install a raised toilet seat in your bathroom." After hip replacement surgery, the client should avoid bending the hip beyond 90 degrees to reduce the risk of dislocation. Installing a raised toilet seat helps the client maintain proper positioning and avoid hip flexion beyond the recommended limit.
