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
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.
