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.)

Calculation: Identify total volume, infusion time, and drop factor Total Volume: 250 mL Time: 30 minutes Drop Factor: 10 gtt/mL Calculate the flow rate Flow Rate (gtt/min) = (Total Volume × Drop Factor) ÷ Time Flow Rate = (250 × 10) ÷ 30 Flow Rate = 2,500 ÷ 30 Flow Rate ≈ 83.33 Round to the nearest whole number = 83 gtt/min
