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. 75 mL/hr B. 150 mL/hr C. 300 mL/hr D. 450 mL/hr

Correct Answer is C

Explanation

To calculate the rate per hour, divide the amount of magnesium sulfate to be administered by the concentration of magnesium sulfate in the IV bag:

6 grams ÷ 40 grams = 0.15

Then, multiply the result by the volume of the IV bag, which is usually 1000 mL: 0.15 x 1000 mL = 150 mL

This is the amount of fluid that contains 6 grams of magnesium sulfate. To administer this amount over 30 minutes, multiply by 2 to get the rate per hour:

150 mL x 2 = 300 mL/hr.
