A physician gives the following order: "Infuse 0.9% sodium chloride solution, 2.5 L over 15 hours." What is the mL/hr flow rate for continuous infusion?

41.67 mL/hr

166.67 mL/hr

250 mL/hr

1000 mL/hr

Answer and Explanation

The Correct Answer is B

To calculate the flow rate in mL/hr for a continuous infusion, we need to divide the total volume to be infused by the total time of infusion, and then convert the units as necessary.

In this case, the total volume is 2.5 L, which is equivalent to 2500 mL (1 L = 1000 mL), and the total time is 15 hours.

Flow rate = Total volume to be infused / Total time of infusion Flow rate = 2500 mL / 15 hours

Flow rate = 166.67 mL/hr

Therefore, the flow rate for continuous infusion of 0.9% sodium chloride solution in this case is 166.67 mL/hr.

Correct Answer is C

Explanation

To calculate the total infusion time, we need to divide the total volume to be infused by the infusion rate:.

Total infusion time = Total volume to be infused / Infusion rate.

In this case, the total volume to be infused is 1000 mL, and the infusion rate is 250 mL/hr:.

Total infusion time = 1000 mL / 250 mL/hr. Total infusion time = 4 hours.

Therefore, the infusion will be completed 4 hours after it was started at 09:20, which would be at 13:20.

A. 50 mL B. 100 mL C. 250 mL D. 500 mL

Correct Answer is C

Explanation

To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..

So the nurse should add 250 mL of water to the formula to dilute it to half strength.
