A nurse is preparing to administer 0.9% sodium chloride 1,200 mL. IV to infuse over 24 hr. 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: Use the formula Flow rate (gtt/min) = (Volume to infuse × Drop factor) ÷ (Time in minutes) Step 2: Insert known values Volume = 1,200 mL Drop factor = 15 gtt/mL Time = 24 hr × 60 min/hr = 1,440 min Flow rate = (1,200 × 15) ÷ 1,440 Flow rate = 18,000 ÷ 1,440 Flow rate = 12.5 Step 3: Round to the nearest whole number 12.5 → 13 gtt/min Final Answer: 13 gtt/min
