Correct Answer is D

Explanation

To calculate the amount of drug per minute, divide the total dose by the infusion time in minutes:

5 mg ÷ 2 minutes = 2.5 mg/minute

The patient should receive 2.5 mg of Lopressor per minute for 2 minutes to get a total dose of 5 mg.

A. 7.5 hours B. 10 hours C. 15 hours D. 20 hours

Correct Answer is D

Explanation

To calculate the time it will take to finish the infusion, we can use the formula:

Time = Volume / Rate

Plugging in the given values, we get: Time = 1.5 L / 75 mL/hr

Converting 1.5 L to mL, we get:

Time = 1500 mL / 75 mL/hr Simplifying, we get:

Time = 20 hours

Therefore, it will take 20 hours to finish the infusion at the current rate.
