A nurse is preparing to administer dextrose 5% in water 500 mL over 12 hr to a client. The nurse should set the IV pump to deliver how many mL/hr?
Correct answer
A
Rationale
The correct answer is A: 42 mL/hr. To calculate the IV pump rate, divide the total volume to be infused by the total time in hours (500 mL ├À 12 hr = 41.67, rounded to 42 mL/hr). This ensures a consistent and accurate delivery of dextrose over the prescribed duration. Choices B, C, and D are incorrect as they do not result from the correct calculation. It's important to calculate the IV pump rate precisely to prevent under or over-infusion, which can lead to potential harm to the client.
