If 2 liters of a parenteral fluid is to be infused over a 14-hour period using an infusion set that delivers 20 drops/mL, (1) should be the rate of flow in drops per minute.

Step 1 is to convert volume and time 2 L × 1000 = 2000 mL 14 hr × 60 = 840 min Step 2 is to calculate drops per minute (2000 × 20) ÷ 840 2000 × 20 = 40000 40000 ÷ 840 = 47.619 Result at this step = 47.619 Step 3 is to round to the nearest whole number 47.619 ≈ 48 Answer: 48
