A nurse is caring for a client who is 4 hr postoperative following a total hip arthroplasty. Which of the following actions should the nurse take?

Rationale: A. Place a pillow between the client's legs: Placing a pillow between the client's legs is essential to maintain hip abduction and prevent dislocation. This keeps the new hip in proper alignment and reduces the risk of complications like dislocation. B. Encourage the client to use an incentive spirometer every 4 hr: Using the spirometer every 4 hours is insufficient. The client should use it every 1-2 hours while awake to prevent atelectasis and promote deep breathing, especially after surgery. C. Maintain the client on bed rest for 12 hr: Strict bed rest for 12 hours is not needed. Early mobilization helps prevent DVT and improve circulation, though activity should be limited to avoid stress on the surgical site. D. Administer a topical antibiotic to the client's incision: Topical antibiotics are usually not given unless specifically ordered. Wound care after hip arthroplasty generally involves sterile dressings and monitoring for infection. Antibiotics if needed are administered systemically.
