Question 1 of 5

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

Correct Answer: C

Rationale: The correct answer is C: Potassium 5.3 mEq/L. Triamterene is a potassium-sparing diuretic. A potassium level of 5.3 mEq/L is elevated, indicating hyperkalemia. Withholding the medication is crucial to prevent further increase in potassium levels, which can lead to serious cardiac arrhythmias.
Choice A, Sodium 142 mEq/L, is within normal range and not a contraindication for triamterene.
Choice B, BUN 16 mg/dL, is also within normal limits and not a reason to withhold the medication.
Choice D, Albumin 4 g/dL, is a measure of protein status and not directly related to the use of triamterene.
