The nurse receives an order for Cefazolin 1 gram in 50 mL of Normal Saline to be infused over 30 minutes. At what rate in mL/hr should the nurse program the IV pump?

Choice A reason: To calculate the infusion rate, divide the total volume (50 mL) by the time in hours (0.5 hours). 50 ÷ 0.5 = 100 mL/hr. This is the correct rate to ensure the medication is infused over 30 minutes. Choice B reason: 50 mL/hr would result in a 1-hour infusion, which is twice the intended duration. Choice C reason: 30 mL/hr would take approximately 1 hour and 40 minutes, which is incorrect. Choice D reason: 75 mL/hr would infuse the medication in 40 minutes, which is faster than prescribed.
