A nurse is reinforcing teaching about high-potassium foods with a client.Which of the following foods should the nurse recommend?
1 cup of sliced cabbage.
1 cup sliced watermelon.
1 medium potato.
1 small apple.
The Correct Answer is C
Choice A rationale
Cabbage is low in potassium, making it a suitable food for clients who need to avoid high-potassium foods. It contains approximately 150 mg of potassium per cup, which is relatively low compared to other vegetables.
Choice B rationale
Watermelon is a fruit with moderate potassium content, containing about 170 mg of potassium per cup. While not extremely high, it is not the best choice for someone seeking to increase potassium intake significantly.
Choice C rationale
A medium potato is high in potassium, with about 900 mg of potassium. Potatoes are an excellent source of potassium, which is essential for maintaining proper muscle and nerve function.
Choice D rationale
An apple is low in potassium, containing around 150 mg per small apple. It is a good option for clients who need to limit their potassium intake, but not for those looking to increase it. .

Explanation
Choice A rationale
Leaving the television on in the client's room can cause confusion and agitation in clients with dementia, leading to an increased risk of falls.
Choice B rationale
Applying a motion sensor mat to the client's bed is an effective way to alert staff if the client attempts to get out of bed, thereby reducing the risk of falls.
Choice C rationale
Raising all four side rails can be considered a form of restraint and can increase the risk of injury if the client attempts to climb over them.
Choice D rationale

Correct Answer is B
Explanation
Choice A rationale
An ecchymotic injection site indicates bruising, which can result from trauma or bleeding at the site but does not suggest a positive tuberculin skin test result. Positive results are based on induration, not discoloration.
Choice B rationale
A 15 mm induration at the injection site is considered a positive result for tuberculin skin test in any population. The size of the induration indicates a significant reaction to the tuberculin antigen, suggesting TB exposure.
Choice C rationale
A 3 mm induration is not considered a positive result for tuberculin skin test in any population. It indicates a minimal reaction that is below the threshold for positivity, suggesting no significant TB exposure.
Choice D rationale
A scabbed injection site indicates improper healing of the test site but does not correlate with a positive tuberculin skin test result. The presence of a scab does not indicate the size of the induration, which is the determining factor for test results. .
