A nurse is caring for a client who had a total hip arthroplasty.
Which of the following actions should the nurse take to prevent hip dislocation?
A.
Place two-bed pillows between the legs when in bed.
B.
Encourage the client to lean forward when attempting to stand.
C.
Remove the wedge device when turning.
D.
Elevate the knees higher than the hips when sitting.
The Correct Answer and Explanation is:
Correct Answer: A. Place two-bed pillows between the legs when in bed.
Explanation:
Total hip arthroplasty (THA), or hip replacement surgery, is a common procedure for managing hip joint damage due to arthritis or injury. Postoperative care is crucial to prevent complications such as hip dislocation. Dislocation occurs when the ball of the hip joint comes out of the socket, which can cause significant pain and necessitate further intervention.
Option A: Place two-bed pillows between the legs when in bed.
Placing two-bed pillows between the legs is a standard practice to prevent hip dislocation after THA. This technique maintains proper hip alignment by keeping the legs in an abducted position, which helps to keep the new hip joint in its proper position within the socket. By preventing excessive adduction (moving the legs toward the midline of the body) or internal rotation of the hip, this intervention significantly reduces the risk of dislocation. It is essential to use pillows that provide adequate support and keep the legs aligned correctly.
Option B: Encourage the client to lean forward when attempting to stand.
Leaning forward while attempting to stand can increase the risk of hip dislocation. After a THA, clients are generally advised to avoid flexing the hip more than 90 degrees to prevent dislocation. Leaning forward might cause excessive hip flexion, potentially leading to dislocation.
Option C: Remove the wedge device when turning.
A wedge device is used to maintain proper alignment of the hip joint. Removing the wedge device when turning the client could disrupt the alignment and increase the risk of dislocation. It is crucial to follow protocols for using these devices to ensure continued protection of the hip joint.
Option D: Elevate the knees higher than the hips when sitting.
Elevating the knees higher than the hips when sitting can cause hip flexion beyond the recommended 90 degrees, increasing the risk of dislocation. Proper seating positions should keep the hips at or below knee level.
In summary, placing two-bed pillows between the legs helps maintain proper hip alignment and is the most effective strategy among the options provided to prevent hip dislocation after a total hip arthroplasty.
