A nurse is caring for a client who is taking triamterene. For which of the following laboratory values should the nurse withhold the medication?

BUN 16 mg/dL

Potassium 5.3 mEq/L

Sodium 142 mEq/L

Albumin 4 g/Dl

Answer and Explanation

The Correct Answer is B

Choice A rationale:

BUN (blood urea nitrogen) measures kidney function and hydration status but is not a specific indicator for withholding triamterene.

Choice B rationale:

Triamterene is a potassium-sparing diuretic. With a potassium level of 5.3 mEq/L, which is elevated, the nurse should withhold the medication to prevent further potassium retention.

Choice C rationale:

Sodium level of 142 mEq/L is within the normal range and does not indicate a need to withhold triamterene.

Choice D rationale:

Albumin level of 4 g/dL is within the normal range and does not directly impact the decision to withhold triamterene.

Dizziness upon standing could indicate orthostatic hypotension, which could be a concern following administration of a diuretic like furosemide.

A. Hct 44% B. WBC count 5,000/mm3 C. Total bilirubin 1.5 mg/dL D. Potassium 4.2 mEq/L

Correct Answer is C

Explanation

Choice A rationale:

A hematocrit (Hct) level of 44% is within the normal range for adults.

Choice B rationale:

A white blood cell (WBC) count of 5,000/mm3 falls within the normal range.

Choice C rationale:

Total bilirubin levels greater than 1.2 mg/dL in adults could indicate liver dysfunction and should be reported to the provider when assessing a client on amitriptyline, which can affect liver function.

Choice D rationale:

A potassium level of 4.2 mEq/L falls within the normal range for potassium levels.
