A nurse is caring for a client whose throat culture is positive for group A streptococcus 24 hours after a rapid strep test (RST) was negative. Which of the following actions is the nurse's priority?

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.

Choice A reason:
Raisins are dried grapes and are known to have a higher concentration of nutrients, including potassium. For individuals with chronic kidney disease (CKD), consuming foods like raisins that are high in potassium can lead to hyperkalemia, a condition where potassium levels in the blood are higher than normal. This can be dangerous as it may cause heart rhythm problems.

Choice B reason:
Asparagus is considered a lower-potassium food, making it a safer choice for people with CKD. It's important for individuals with CKD to manage their potassium intake, but asparagus can be included in their diet in appropriate portions.

Choice C reason:
Bananas are well-known for being rich in potassium. For someone with CKD, eating bananas can contribute to an excessive intake of potassium, which their kidneys may not be able to eliminate efficiently, potentially leading to hyperkalemia.

Choice D reason:
Tomatoes, including tomato products like sauces, juices, and purees, are high in potassium. Therefore, they should be limited or avoided in the diet of a person with CKD to prevent complications associated with high potassium levels.

Choice E reason:
Green beans are considered to be a lower-potassium vegetable. They can be included in a kidney-friendly diet, provided they are consumed in moderation and balanced with other dietary needs.
