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 nurse to administer cefazolin: We know: Total volume of solution: 50 mL (given) Dose of cefazolin: 1 gram (given) = 1000 milligrams (since 1 gram = 1000 milligrams) Infusion duration: 30 minutes (given) = 0.5 hours (convert minutes to hours by dividing by 60) We need to find: Infusion rate (mL/hour) Calculation: Calculate the concentration of cefazolin in the solution (not required, but helpful to understand): We aren't directly given the concentration, but we can see that 1 gram of cefazolin is delivered in 50 mL. Therefore, the concentration is: Concentration = Dose (mg) / Volume (mL) Concentration = 1000 mg / 50 mL Concentration = 20 mg/mL Calculate the infusion rate based on the total volume and duration: Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours) Infusion rate (mL/hour) = 50 mL / 0.5 hours Infusion rate (mL/hour) = 100 mL/hour Since we typically round infusion rates to whole numbers for ease of use with infusion pumps, the nurse should program the pump to deliver 100 mL/hour.
