Which intervention should a nurse include in the care plan for a client following total hip arthroplasty to reduce the risk of hip dislocation?

Placing a pillow between the client's legs is a crucial intervention following total hip arthroplasty to minimize the risk of hip dislocation. This practice helps to maintain proper alignment of the hip joint, providing a physical barrier that keeps the legs separated. By preventing excessive adduction (bringing the legs together), the pillow reduces the risk of the femoral head dislocating from the acetabulum, which is a common concern after hip surgery, particularly if the patient moves in a way that could compromise the joint's stability.

Maintaining proper positioning is particularly important in the immediate postoperative period, as the surrounding soft tissues and ligaments heal. The use of a pillow helps reinforce the appropriate position while the patient is lying on their back, promoting safety and stability during recovery. This intervention is a standard part of hip replacement protocols to enhance patient safety and recovery outcomes.
