Question

The physician orders 400 mL of 0.9% NS to infuse over 30 minutes. The nurse should set the infusion pump to run at ___ mL/hr? Answer as a whole number without any decimals. Do not include the unit of measurement in your answer.

Answer 1

To calculate the infusion rate in mL/hr, we need to convert the time from minutes to hours and set up a proportion. The nurse should set the infusion pump to run at 13 mL/hr.

Step-by-step explanation:

To calculate the infusion rate in mL/hr, we need to convert the time from minutes to hours. Since we know that the physician ordered 400 mL to infuse over 30 minutes, we can set up a proportion:

400 mL / 30 minutes = x mL / 1 hour

Cross-multiplying, we get:

30 * x = 400

Solving for x, the infusion rate in mL/hr, we get:

x = 400 / 30 = 13.3333...

Rounding to the nearest whole number, the nurse should set the infusion pump to run at 13 mL/hr.
