A solution is to be administered by intravenous infusion at a rate of 45 mL/h. (1) drops/min should be infused if the administration set deliver 40 drops/mL. Round answer to the nearest whole number. Do not include units.

Step 1 is to identify the volume per hour and the drop factor Volume: 45 mL Time: 60 minutes Drop Factor: 40 drops/mL Step 2 is to calculate the drops per minute (gtt/min) (Total Volume × Drop Factor) ÷ Time in minutes (45 × 40) ÷ 60 45 × 40 = 1800 1800 ÷ 60 = 30 Result at this step = 30 Step 3 is to round to the nearest whole number 30 = 30
