Question 1 of 5

A nurse is caring for a client who is to receive potassium replacement. The provider's prescription reads, 'Potassium chloride 30 mEq in 0.9% sodium chloride 100 mL IV over 30 min.' For which of the following reasons should the nurse clarify this prescription with the provider?

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

Correct Answer: A

Rationale: The correct answer is A: The potassium infusion rate is too rapid. The nurse should clarify this prescription with the provider because administering 30 mEq of potassium chloride in 100 mL over 30 minutes is too rapid and may lead to adverse effects like hyperkalemia or cardiac arrhythmias. Potassium replacement should be infused slowly over several hours to prevent complications.

Choices B, C, and D are incorrect because the prescription specifies the use of potassium chloride in sodium chloride solution, not another formulation or dilution in dextrose. IV bolus administration of potassium is also contraindicated due to the risk of rapid electrolyte shifts.
