A nurse is preparing a client for intradermal tuberculin skin testing (TST). Which of the following statements should the nurse make?

“An indurated area of 4 millimeters indicates a positive result.”.

“The injection site will be evaluated within 24 hours.”.

“A positive result does not always indicate active disease.”.

“The test will not be administered if you have had a previous negative result.”. .

Answer and Explanation

The Correct Answer is C

Choice A rationale
An indurated area of 4 millimeters is not considered a positive result for tuberculin skin testing. The size of induration considered positive varies based on the individual’s risk factors and health status.
Choice B rationale
The injection site for a tuberculin skin test should be evaluated between 48 and 72 hours after administration, not within 24 hours. Evaluating it too early may not provide accurate results.
Choice C rationale

A positive result in a tuberculin skin test indicates that the person has been infected with TB bacteria, but it does not necessarily mean they have active TB disease. Further tests are needed to determine if the disease is active.
Choice D rationale
A previous negative result does not preclude the administration of a new tuberculin skin test. Individuals can be retested if there is a new risk of exposure or if it is required for medical or occupational reasons.

Correct Answer is C

Explanation

Choice A rationale
Cabbage is not a significant source of potassium. While it is a healthy vegetable, it does not provide the necessary potassium to help raise serum potassium levels.
Choice B rationale
Cheddar cheese is also not a high-potassium food. It is rich in calcium and protein but does not significantly contribute to potassium intake.
Choice C rationale
Bananas are well-known for their high potassium content. Including bananas in the diet can help increase serum potassium levels, which is beneficial for a client taking furosemide, a diuretic that can cause potassium loss.

Choice D rationale
Potatoes are another excellent source of potassium. However, the question specifies choosing one food, and bananas are a more commonly recommended option for increasing potassium intake.
