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:

A BUN level of 16 mg/dL is within a normal range.

Choice B rationale:

A potassium level of 5.3 mEq/L is higher than the normal range (typically 3.5-5.0 mEq/L). Triamterene is a potassium-sparing diuretic, and if the client's potassium level is already elevated, it should be withheld to prevent hyperkalemia.

Choice C rationale:

A sodium level of 142 mEq/L is within a normal range.

Choice D rationale:

An albumin level of 4 g/dL is within a normal range.

Correct Answer is ["0.4"]

Explanation

To answer this question, we need to use the formula for calculating the dosage of medication:

Dose ordered / Dose on hand = Amount to administer

The calculation is: 4,000 units / 10,000 units/mL = 0.4 mL.

A. The client should be treated by giving potassium by IV bolus. B. Another formulation of potassium should be given IV. C. Potassium chloride should be diluted in dextrose 5% in water. D. The potassium infusion rate is too rapid.

Correct Answer is D

Explanation

Choice A rationale:

IV bolus administration of potassium is not appropriate due to the risk of cardiac arrhythmias.

Choice B rationale:

The formulation of potassium (potassium chloride) is appropriate for IV administration.

Choice C rationale:

Potassium chloride is typically diluted in normal saline (0.9% sodium chloride) for IV administration, not dextrose.

Choice D rationale:

The prescribed infusion rate of 30 mEq of potassium chloride over 30 minutes is too rapid and could lead to adverse effects, such as cardiac arrhythmias. The nurse should clarify the prescription and discuss a slower infusion rate with the provider.
