A nurse is preparing to administer cefazolin 1 g intermittent IV bolus in 0.9% sodium chloride 250 mL over 30 min. The drop factor on the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV flow rate 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.) ________ gtt/min

Step 1 is to identify the total volume to be infused and the time in minutes Total Volume = 250 mL Time = 30 minutes Step 2 is to identify the drop factor Drop Factor = 10 gtt/mL Step 3 is to calculate the flow rate in drops per minute (gtt/min) gtt/min = (Total Volume ÷ Time in minutes) × Drop Factor gtt/min = (250 ÷ 30) × 10 250 ÷ 30 = 8.3333... 8.3333... × 10 = 83.3333... Step 4 is to round to the nearest whole number 83.3333... ≈ 83 Answer: 83
