The nurse, working with patients in an orthopedic surgical unit, wants to study the impact of assistive devices on progressive ambulation. What would be an example of a research problem for this study?
1. Do post–hip replacement patients ambulate faster with one crutch or two?
2. How does learning postsurgical exercises before the hip replacement impact the patient's use of assistive devices?
3. Will post–hip replacement patients recover from surgery faster if ambulated the day after surgery?
4. Will post–hip replacement surgery patients be discharged using a cane for ambulation?

Rationale 1: The research problem is a small, specific piece of a phenomenon to be studied. The question that best supports the nurse's focus would be whether post–hip replacement patients ambulate faster with one crutch or two.
Rationale 2: This question focuses on assistive devices, not on progressive ambulation.
Rationale 3: This question does not specifically address the use of assistive devices.
Rationale 4: This question is about discharge rather than about the impact of assistive devices on progressive ambulation.
