A nurse is caring for a client who has tuberculosis and is about to start taking pyrazinamide.
The nurse should identify that the client needs which of the following tests while taking this medication therapy?

Choice A rationale:

Bananas are a good source of potassium, and the client's serum potassium level is low (3.1 mEq/L). Including potassium-rich foods like bananas in the diet can help raise the potassium level and prevent hypokalemia, which is a potential side effect of furosemide (a diuretic).

Choice B rationale:

Cheddar cheese is not a suitable choice for a client with low potassium levels. It is not a significant source of potassium and should not be the primary recommendation for addressing hypokalemia.

Choice C rationale:

Cabbage is not a good choice for increasing potassium intake. While it has some potassium, other fruits and vegetables like bananas are much richer sources of this essential electrolyte.

Choice D rationale:

White rice is not a high-potassium food and should not be the first choice for a client with low potassium levels.

Choice A rationale:

Taking hydrochlorothiazide on an empty stomach is not a requirement for this medication. Hydrochlorothiazide is a diuretic used to treat conditions like hypertension and edema. It can be taken with or without food, and food may help reduce stomach upset for some individuals.

Choice B rationale:

Muscle weakness is an adverse effect of hydrochlorothiazide. Therefore, it is not an expected outcome. Hydrochlorothiazide is a thiazide diuretic, and one of its common side effects is potassium loss through increased urine output. This can lead to muscle weakness and cramping. The nurse should educate the client about the signs and symptoms of low potassium and the importance of including potassium-rich foods in their diet.

Choice C rationale:

Increasing daily intake of foods high in potassium is essential information to include in the teaching for a client taking hydrochlorothiazide. Thiazide diuretics like hydrochlorothiazide can cause potassium depletion, which may result in adverse effects like muscle weakness, cramping, and cardiac dysrhythmias. Therefore, advising the client to consume potassium-rich foods, such as bananas, oranges, and potatoes, can help counteract the potassium loss associated with the medication.

Choice D rationale:

Taking the medication at bedtime is not a specific requirement for hydrochlorothiazide. Thiazide diuretics can be taken at various times of the day, depending on the client's preferences and when they are most compliant with their medication regimen. The timing of administration should be consistent to maintain the medication's effectiveness.
