A client scheduled for coronary artery bypass surgery is to receive an intravenous (IV) 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.)

Here's how to calculate the infusion rate (mL/hour) for the cefazolin administration: 1. We know: Total volume of cefazolin solution (including 0.9% sodium chloride): 50 mL (given) Amount of cefazolin to administer: 1 gram (convert to mg for calculation) = 1 g * 1000 mg/g = 1000 mg Infusion time: 30 minutes (given) = 30 minutes / 60 minutes/hour = 0.5 hours 2. We need to find: Infusion rate (mL/hour) 3. Calculation: The medication (cefazolin) is diluted in sodium chloride solution, but the total volume (50 mL) includes both. We only need to administer this entire volume over the specified time. Infusion rate (mL/hour) = Total volume of solution (mL) / Infusion time (hours) Infusion rate (mL/hour) = 50 mL / 0.5 hours Infusion rate (mL/hour) = 100 mL/hour Therefore, the nurse should program the infusion pump to deliver 100 mL/hour.
