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:
To calculate the IV infusion rate in drops per minute (gtt/min), we use the formula: (Volume to be infused in mL ÷ Time in minutes) x Drop factor. In this case, the volume to be infused is 100 mL over 30 min, and the drop factor is 15 gtt/mL. So, (100 mL ÷ 30 min) x 15 gtt/mL = 50 gtt/min. This ensures the accurate delivery of cefazolin within the specified time frame. Other choices are incorrect because they do not accurately calculate the required infusion rate based on the given parameters.
