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. 2 mL B. 3 mL C. 4 mL D. 5 mL

Correct Answer is C

Explanation

The ordered dose is 400 mcg, which is equal to 0.4 mg..

The medication is provided as 0.1 mg/mL, so to administer 0.4 mg, the nurse needs to give:.

0.4 mg ÷ 0.1 mg/mL = 4 mL.

Therefore, the nurse should administer 4 mL of atropine sulfate.
