-Jackie's intravenous infusion, 1 L of 5% dextrose (she is not currently taking food or fluids), has 70 ml remaining and is dripping at 60 drops/minute. Remembering that the drop factor for the giving set is 20 drops/ml, this infusion should complete in
A) 20 minutes

To calculate the time remaining for the infusion to complete, you can use the formula: Time = Volume / Rate. The volume remaining is 70 ml, and the rate is calculated by dividing the current drip rate (60 drops/minute) by the drop factor (20 drops/ml), which equals 3 ml/minute. Therefore, the time remaining is 70 ml / 3 ml/minute = 23.33 minutes, which rounds to approximately 23 minutes.
