A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 mL via intermittent IV bolus over 30 minutes. 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? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the IV infusion rate in drops per minute (gtt/min), we can use the formula: (Volume to be infused in mL x Drop factor) / Time in minutes. In this case, the volume to be infused is 100 mL, drop factor is 15 gtt/mL, and the time is 30 minutes. Plugging these values into the formula: (100 mL x 15 gtt/mL) / 30 minutes = 1500 gtt / 30 minutes = 50 gtt/min. Therefore, the correct answer is 50 gtt/min. This rate ensures the cefazolin is administered over the desired 30-minute timeframe. Other choices are incorrect because they do not align with the calculated rate based on the given parameters.
