A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hr. The drop factor of the manual IV tubing is 60 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 = 400 mL Drop factor = 60 gtt/mL Time = 8 hr × 60 min/hr = 480 min Flow rate = (400 × 60) ÷ 480 Flow rate = 24,000 ÷ 480 Flow rate = 50 gtt/min Final Answer: 50 gtt/min
