A nurse is reinforcing discharge teaching with a client following a total hip arthroplasty. Which of the following client statements indicates an understanding of the teaching?

The client scenario requires the application of postoperative care principles following total hip arthroplasty. Successful discharge teaching relies on knowledge of proper joint alignment, dislocation prevention strategies, correct positioning techniques, and specific mobility restrictions to ensure safe recovery. Choice A rationale Crossing the legs adducutes the operative hip past the midline of the body. This specific movement severely increases the risk of joint dislocation by disrupting the precise anatomical alignment maintained by the newly implanted prosthetic components. Choice B rationale Daily rehabilitation exercises are essential immediately after discharge to prevent joint contractures and muscle atrophy. Delaying these targeted therapeutic activities for months impairs functional mobility, delays recovery, and significantly reduces long-term joint stability. Choice C rationale Placing a pillow between the legs maintains optimal hip abduction during rest. This proper positioning technique prevents accidental adduction across the anatomical midline, thereby effectively minimizing the risk of postoperative dislocation of the prosthetic joint. Choice D rationale Sitting in low chairs forces the operative hip into a flexed position greater than 90 degrees. This extreme flexion exceeds safe mechanical limits, placing excessive stress on the posterior capsule and increasing the risk of dislocation.
