Question

50 mL of sodium chloride 0.45% is prescribed over 12 minutes. What is the rate in mL/hr ? A. 250 mL/hr B. 300 mL/hr C. 360 mL/hr D. 400 mL/hr

Answer 1

The rate in mL/hr can be calculated by dividing the volume by the time in hours.

Step-by-step explanation:

To calculate the rate in mL/hr, we need to convert the time from minutes to hours. Since there are 60 minutes in 1 hour, we can calculate the rate by dividing the volume (50 mL) by the time in hours (12/60 = 0.2 hours). So, the rate in mL/hr is 50 mL divided by 0.2 hours, which equals 250 mL/hr. Therefore, the correct answer is A. 250 mL/hr.
