Ati RN Pharmacology 2019 - Exam 3 ( 60 Questions)
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 (blood urea nitrogen) measures kidney function and hydration status but is not a specific indicator for withholding triamterene.
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.
Sodium level of 142 mEq/L is within the normal range and does not indicate a need to withhold triamterene.
Albumin level of 4 g/dL is within the normal range and does not directly impact the decision to withhold triamterene.
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.
