Difficulty: MediumBasic Care and Comfort

An older adult client has been transferred to the medical-surgical unit following a left total hip arthroplasty via a posterior approach. The practical nurse is assisting with the client's initial positioning in bed. Which action should the nurse take to maintain correct body alignment and prevent joint dislocation?

  1. Secure an abduction pillow between the client's lower extremities before turning them.Answer
  2. B
    Elevate the head of the bed to a high-Fowler's position to assist with eating and breathing.
  3. C
    Rotate the client's left leg internally to decrease tension on the surgical incision.
  4. D
    Place a large rolled pillow directly under the client's left knee to promote comfort.

Answer

Secure an abduction pillow between the client's lower extremities before turning them.
Following a posterior total hip arthroplasty, the client's hip must be kept in a neutral position with slight abduction to prevent the head of the femur from dislocating. An abduction pillow safely prevents adduction (crossing the legs past the midline) and maintains structural stability while the client is resting or being turned.

Step-by-Step Solution

1
Identify the surgical procedure and approach.
The client had a left total hip arthroplasty using a posterior approach.
Different surgical approaches have different post-operative positioning restrictions to prevent dislocation.
2
Determine the contraindicated movements for a posterior hip replacement.
Avoid hip flexion greater than 90 degrees, adduction across the midline, and internal rotation.
These specific movements force the head of the femur backward, pushing it out of the newly repaired joint space.
3
Select the nursing action that complies with these positioning restrictions.
Using an abduction pillow between the legs prevents adduction and maintains neutral alignment.
This device ensures the legs remain slightly spread apart (abducted) during turning and resting, protecting the new hip joint.
