Order: Infuse 1,000 mL NS over 8 hours using a 10 gtt/mL set. Calculate the flow rate in drops per minute.

Step 1: Convert time to minutes 8 hr × 60 min/hr = 480 min Step 2: Use the formula Flow rate (gtt/min) = (Volume × Drop factor) ÷ Time in minutes Flow rate = (1,000 × 10) ÷ 480 Flow rate = 10,000 ÷ 480 ≈ 20.83 Step 3: Round to the nearest whole number Flow rate ≈ 21 gtt/min Final Answer: 21 gtt/min
