A nurse is preparing to administer dextrose 5% in water (D,W) 150 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 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 = 150 mL Drop factor = 10 gtt/mL Time = 3 hr × 60 min/hr = 180 min Flow rate = (150 × 10) ÷ 180 Flow rate = 1,500 ÷ 180 Flow rate ≈ 8.33 Step 3: Round to the nearest whole number Flow rate ≈ 8 gtt/min Final Answer: 8 gtt/min
