A nurse is developing a care plan for a client who is in Buck's traction and is scheduled for surgery for a fractured femur of the right leg. Which of the following interventions should the nurse delegate to assistive personnel?

Correct Answer: D. Remind the client to use the incentive spirometer.

Rationale:
1. Incentive spirometer use is a task that can be safely delegated to assistive personnel.
2. It is a non-invasive procedure and does not require advanced nursing skills.
3. Using the incentive spirometer helps prevent respiratory complications post-surgery.
4. Assistive personnel can remind the client to use it regularly, promoting lung expansion and preventing atelectasis.

Summary of other choices:
A: Asking the client to describe pain requires nursing assessment skills.
B: Checking the client's pedal pulse requires nursing assessment skills.
C: Observing the position of the suspended weight requires nursing judgment to adjust if needed.
