Nokea
The nurse reinforces instructions for the patient who is to have a unicompartmental knee replacement that which is a major advantage of this partial knee replacement?
- A. the patient will be up and walking 2 to 3 hours after the operation.
- B. the kneecap is completely removed.
- C. the procedure is especially helpful in the treatment of rheumatoid arthritis (RA).
- D. a small titanium disk replaces the worn cartilage.
Correct Answer: A
Rationale: Unicompartmental knee arthroplasty is also referred to as partial knee replacement in which the worn cartilage is replaced with a plastic disk. It is not as invasive as a full knee replacement and does not disturb the kneecap so that the patient can be up and walking in 2 to 3 hours after surgery. It is not recommended for patients with Rheumatoid Arthritis.

- A. Ankylosing spondylitis
- B. Pathologic fractures
- C. Osteomyelitis

- A. Keeping the joints from 'freezing.'
- B. Ensuring longer and better sleep.
- C. Stimulating joints when done vigorously

The patient that has a bipolar hip replacement following an intracapsular fracture has an order to be turned every 2 hours. The nurse understands that the correct nursing intervention is to keep the legs in which position?
- A. together so they do not separate while turning.
- B. flexed to stabilize the prosthesis.
- C. abducted so the prosthesis does not become dislocated.
- D. adducted to prevent additional pain for the patient with turning.
Correct Answer: C
Rationale: Nursing interventions also involve postoperative maintenance of leg abduction by using an abduction splint for 7 to 10 days to prevent dislocation of the prosthesis. Leg abduction does not involve keeping the legs together, flexion to stabilize the prosthesis or to keep the legs adducted to prevent additional pain with turning.
