Final answer:
The correct position for a client postoperative following a hip arthroplasty when sitting in a chair is to sit with feet flat on the floor, which helps maintain proper hip joint alignment and prevent dislocation.
Step-by-step explanation:
Following a right hip arthroplasty, it is crucial for a patient to maintain the correct position while sitting to promote healing and avoid dislocation. The correct position for a client postoperative following a hip arthroplasty when sitting in a chair is to sit with feet flat on the floor. This ensures that the hip remains in a stable, neutral position without excessive flexion, adduction, or internal rotation that could compromise the integrity of the hip joint and surrounding tissues.
According to Figure 9.18 in the provided reference, the hip joint is a ball-and-socket joint that provides stability and a wide range of motion, and the supporting ligaments pull the head of the femur into the acetabulum when standing. This ligament tension and alignment need to be maintained through proper positioning even when seated. Crossing legs or sitting with the feet on an elevated surface could potentially alter the alignment of the hip components and stress the joint.
Furthermore, the replacement components, as mentioned in the provided material, function properly when correctly aligned. Ensuring proper sitting posture is a key part of postoperative care. For example, leaning forward or sitting in a way that increases hip flexion beyond 90 degrees could risk dislocation of the prosthetic joint. Therefore, options a, c, and d are not advisable positions for a patient with a recent hip replacement surgery.
