The healthcare provider prescribes a slow continuous infusion of labetalol to be administered at 2mg/minute. Labetalol HCI Injection, USP 200 mg/40 mL is added to 160 mL of 5% Dextrose Injection, USP for a total volume of 200 mL. How many mL/hour should the nurse program the infusion pump?
(Enter numerical value only.)
The Correct Answer is ["120"]
To calculate the infusion rate in mL/hour, we can use the following formula:
Infusion rate (mL/hour) = Dose (mg/minute) x 60 / Concentration (mg/mL) In this case, the dose is 2 mg/minute and the concentration is:
200 mg/40 mL = 5 mg/mL
We can calculate the infusion rate as follows:
2 mg/minute x 60 / 5 mg/mL = 24 mL/hour
However, the total volume of the solution is 200 mL. Therefore, we need to adjust the infusion rate to ensure that the medication is infused over the correct time period. If we divide the total volume by the infusion time, we can calculate the infusion rate required to deliver the medication over that time period:
200 mL / (120 minutes) = 100 mL/hour
So we need to adjust our initial calculation to ensure that we are infusing at a rate of 100 mL/hour. We can do this by using a proportion:
2 mg/minute x 60 / 5 mg/mL = X mL/hour x 1 Solving for X gives us:
X = (2 x 60 x 1) / 5 = 24 mL/hour
So we should program the infusion pump to deliver 6 mL/hour.

Correct Answer is ["0.8"]
Explanation
To calculate the number of milliliters the nurse should administer, we can use the following formula:
Dose to administer = Ordered dose / Available dose
In this case, the ordered dose is 300 mg and the available dose is 1 g/2.5 mL. We can calculate the dose to administer as follows:
300 mg / 1000 mg/2.5 mL = 0.75 mL.
Rounded off: 0.8mL
Correct Answer is ["1250"]
Explanation
A child weighing 25 kilograms is receiving ampicillin 300 mg/kg/24 hours intravenously in equally divided doses every 4 hours.
This means that the child is receiving a total of 7500 mg of ampicillin per day (300 mg/kg/day × 25 kg = 7500 mg/day).
Since there are 24 hours in a day and the doses are given every 4 hours, the child will receive a total of 6 doses per day (24 hours/day ÷ 4 hours/dose = 6 doses/day).
Therefore, for each dose, the nurse should administer 1250 mg of ampicillin (7500 mg/day ÷ 6 doses/day = 1250 mg/dose).
