Quizplus · Accepted Answer

The total volume of the solution is 8 ml (medication) + 42 ml (fluid) = 50 ml. With a drop factor of 20 drops/ml, the total number of drops is 50 ml * 20 drops/ml = 1000 drops. To infuse this over 15 minutes, the rate is 1000 drops / 15 minutes = 66.67 drops/minute, which rounds to 67 drops/minute.
