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.)

Step 1: Determine the total volume to be infused. 100 mL Step 2: Determine the time in minutes over which the infusion will be administered. 30 minutes Step 3: Calculate the flow rate in mL/min. 100 mL ÷ 30 minutes = 3.33 mL/min Step 4: Calculate the flow rate in gtt/min using the drop factor. 3.33 mL/min × 15 gtt/mL = 49.95 gtt/min Step 5: Round to the nearest whole number. 50 gtt/min The nurse should set the manual IV infusion to deliver 50 gtt/min.
