Question

A physician orders morphine sulfate 100 mg/100 mL in normal saline to be infused at a rate of 2 mg/hour for a patient. What volume in mL should the patient receive per hour? A. 2 mL B. 12 mL C. 20 mL D. 0.2 mL

Answer 1

A. 2 mL

Explanation:

The amount of drug is proportional to the volume of solution. We want 2 mg of drug. We can find the amount of solution (s) from ...

100 mL/(100 mg) = s/(2 mg)

Multiplying this by 2 mg gives ...

100 mL · (2/100) = s = 2 mL

The patient should receive 2 mL per hour.
