Rn Hesi Med Surg Dosage Calculations ( 55 Questions)
A client scheduled for coronary artery bypass surgery is to receive an intravenous infusion of 1 gram cefazolin in 50 mL 0.9% Sodium Chloride, USP over 30 minutes. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only, as a whole number.)
To answer this question, we need to calculate the infusion rate in mL/hour using the formula:
Infusion rate (mL/hour) = Volume (mL) / Time (hour)
We are given the volume of the infusion as 50 mL and the time as 30 minutes. We need to convert the time from minutes to hours by dividing by 60. Therefore, we get:
Infusion rate (mL/hour) = 50 mL / (30 / 60) hour
Infusion rate (mL/hour) = 50 mL / 0.5 hour
Infusion rate (mL/hour) = 100 mL/hour
The nurse should program the infusion pump to deliver 100 mL/hour. This is the numeric value and it is already a whole number, so no rounding is needed.
