A primary healthcare provider prescribes a medication of 1250 mg diluted in 1000 mL. A nurse starts the infusion at 09:20 at a rate of 250 mL/hr. What time will the intravenous (IV) infusion be completed?

11:20

12:20

13:20

14:20

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

We can use the formula for calculating infusion time:. Infusion time = Total volume / Infusion rate.

First, we need to convert the volume of the fluid from liters to milliliters:.

0.75 L = 750 mL.

Next, we can plug in the values we have:. Infusion time = 750 mL / 120 mL/hr.

Infusion time = 6.25 hours.

Since the infusion was started at 9:00 a.m., we can add 6.25 hours to determine when the infusion will be completed:.

9:00 a.m. + 6.25 hours = 3:15 p.m..

Therefore, the infusion will be completed at 3:15 p.m.

A. 21 B. 31 C. 52 D. 62

Correct Answer is B

Explanation

The correct answer is choice B. 31. To find the number of bottles required, use the formula: (dose x frequency x duration) / (bottle size x bottle concentration). In this case, (4 mg/kg x 43 kg x 3 times/day x 6 days) / (100 mg/bottle) = 30.96 bottles. Round up to the nearest whole number to get 31 bottles.
