Question 1 of 5
A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 mL via intermittent IV bolus over 30 min. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?
Correct Answer: A
Rationale: The correct answer is A: 50 gtt/min.
To calculate the IV infusion rate, we need to determine the total volume to be infused over 30 minutes. The total volume to be infused is 100 mL. Convert the volume to drops by multiplying it by the drop factor (100 mL x 15 gtt/mL = 1500 gtt).
To find the rate in gtt/min, divide the total volume by the time in minutes (1500 gtt รท 30 min = 50 gtt/min). Setting the manual IV infusion to deliver 50 gtt/min ensures the cefazolin is administered correctly. Other choices are incorrect because they do not follow the correct calculation process or result in different infusion rates.
