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.)

Calculation: Total volume to infuse = 50 mL. Total infusion time and convert to hours. Infusion time = 30 minutes = 30 minutes / 60 minutes/hour = 0.5 hours. Calculate the infusion rate in milliliters per hour (mL/hr). Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr) = 50 mL / 0.5 hr = 100 mL/hr.
