Which of the following questions is most important to ask a client who might have been exposed to HIV after being sexually assaulted?

Choice A reason:
It is important to keep a Plaster of Paris cast dry because moisture can weaken the cast and irritate the skin underneath. Therefore, the cast should be covered while showering to prevent it from getting wet.

Choice B reason:
Applying ice to the foot after walking can help reduce swelling and provide pain relief. It is a common recommendation for managing discomfort associated with a walking cast. The ice should be applied over the cast at the level of the injury for 15-30 minutes, repeating every few hours for the first few days.

Choice C reason:
While a musty odor can develop over time due to sweat and lack of air circulation, it is not necessarily normal and could indicate a problem such as an infection. If there is a persistent unpleasant odor, it should be evaluated by a healthcare provider.

Choice D reason:
Numbness or pain in the toes can be a sign of compromised circulation or nerve compression and should be reported immediately. It is crucial to monitor for any changes in sensation or increased pain, as these could indicate a serious issue that requires medical attention.

Choice A reason:

The inability to abduct the arm at the shoulder is a classic sign of a rotator cuff injury. The rotator cuff is responsible for stabilizing the shoulder joint and aiding in various movements, including abduction. When there is a tear or significant weakness in the rotator cuff muscles, especially the supraspinatus muscle, the patient may be unable to lift the arm away from the body or may experience pain while doing so.

Choice B reason:

A negative drop arm test would actually indicate that there is no rotator cuff injury. The drop arm test is performed by asking the patient to fully abduct the arm to 90 degrees and then slowly lower it. If the patient can control the motion and lower the arm smoothly, the test is negative. A positive drop arm test, where the patient cannot control the descent of the arm, would suggest a rotator cuff tear.

Choice C reason:

While an alteration in the contour of the joint may indicate some form of shoulder pathology, it is not specific to a rotator cuff injury. Changes in the contour could be due to various conditions, including dislocation, arthritis, or other musculoskeletal disorders.

Choice D reason:

A positive Tinel's sign is used to diagnose nerve compression or nerve damage, not rotator cuff injuries. It is performed by tapping over the course of a nerve to elicit a tingling sensation or pain in the distribution of the nerve. This sign is commonly associated with conditions like carpal tunnel syndrome.
