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.

A. 1 tablet B. 2 tablets C. 3 tablets D. 4 tablets E. 4 tablets

Correct Answer is C

Explanation
