A nurse is teaching a client who is scheduled for dual-energy x-ray absorptiometry (DXA) to screen for osteoporosis. Which of the following instructions should the nurse include in the teaching?
"You will need to fast for 12 hours before the test."
"You will need to lie flat for 4 hours following the test."
"You will need to remove all jewelry before the test."
"You will need to empty your bladder before the test."
The Correct Answer is C
A. Fasting is not necessary for a dual-energy x-ray absorptiometry (DXA) scan, as it does not involve ingesting anything.
B. The client does not need to lie flat for an extended period following a DXA scan. They can resume normal activities immediately after the test.

Correct Answer is ["A","C","D","E"]
Explanation
A. Place a compression bandage on the ankle.
- This helps reduce swelling and provides support to the injured area.
B. Apply heat to the ankle
- This action is not recommended for acute sprains as it can increase swelling. Cold packs or ice should be used initially to reduce inflammation.
C. Encourage rest.
- Rest is important to allow the ankle to heal properly and prevent further injury.
D. Elevate the ankle.
- Elevating the ankle helps reduce swelling by allowing fluid to drain away from the injured area.
E. Perform passive range-of-motion exercises to the ankle.
- Gentle range-of-motion exercises can help prevent stiffness in the ankle joint. However, it's important to perform these exercises within the limits of comfort and not force any movements.
Correct Answer is B
Explanation
A: Placing the client in protective isolation is not necessary unless the client is immunocompromised or has another indication for isolation beyond the scoliosis repair.
B: A PCA (patient-controlled analgesia) pump allows the client to manage pain effectively by administering their own pain medication within prescribed limits, which is essential after the significant surgical intervention of scoliosis repair.
C: Keeping the head of the bed at a 30° angle is not specifically indicated for postoperative care following scoliosis repair with Harrington rod instrumentation. The position of the bed should be based on the client's comfort and specific postoperative orders.
D: Repositioning the client by log rolling every 4 hours is important to prevent complications such as pressure ulcers and to promote circulation, but it is not the priority intervention. Pain management postoperatively is crucial for client comfort, promoting mobility, and aiding in the recovery process.
