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?

The correct answer is D: The potassium infusion rate is too rapid. Potassium replacement via IV should be administered at a rate that reduces the risk of adverse effects, such as cardiac arrhythmias. Administering 30 mEq of potassium chloride in 100 mL over 30 minutes could result in a rapid infusion rate, potentially leading to hyperkalemia and cardiac complications. Therefore, the nurse should clarify this prescription with the provider to ensure a safer infusion rate.

Other options are incorrect:
A: The client should not receive potassium via IV bolus as it can cause serious adverse effects.
B: There is no indication that another formulation of potassium is necessary.
C: Potassium chloride should be diluted in saline, not dextrose, for IV administration, so this is not a reason to clarify the prescription.
