A home health nurse is caring for a client who is postoperative following a total hip arthroplasty. Which of the following interventions should the nurse recommend to promote recovery?

After total hip arthroplasty, the primary concern is preventing hip dislocation by avoiding flexion of the hip beyond 90 degrees. Using an elevated toilet seat raises the seat height so the client does not have to bend the hip past the 90-degree restriction when sitting down or rising from the toilet, making it an essential adaptive device during recovery. Taking baths instead of showers is contraindicated because getting in and out of a bathtub requires excessive hip flexion and increases fall risk; showers with a shower chair are preferred. Crossing legs at the ankles is incorrect because crossing the legs at any point — whether at the knees or ankles — can cause hip adduction past the midline, which is a major dislocation risk after hip arthroplasty. Using a walker on stairs is also incorrect; clients with hip replacements are instructed to avoid stairs initially and to use crutches or a cane on stairs only as directed, never a walker, because walkers are unstable on stairs and increase fall risk significantly. The elevated toilet seat directly addresses both the mobility restriction and safety during a high-risk daily activity.
