A child who weighs 42 kg receives a prescription for methylprednisolone succinate 1.5 mg/kg/day intravenously in divided doses every 6 hours. The medication is available in 40 mg/mL vials. How many mL should the nurse administer with each dose?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.4"]
To calculate the amount of methylprednisolone succinate the child receives with each dose, we need to divide the daily dose by the number of doses per day and then divide by the concentration of the medication.
The daily dose is 1.5 mg/kg/day, the number of doses per day is 4 (every 6 hours), and the concentration of the medication is 40 mg/mL. Therefore, the amount of methylprednisolone succinate is:
(1.5 mg/kg/day x 42 kg) / 4 / 40 mg/mL = 0.39 mL
The nurse should administer 0.4 mL (rounded to the nearest tenth) with each dose.

Correct Answer is ["100"]
Explanation
To answer this question, the nurse needs to calculate the infusion rate for the ganciclovir IV bag.
The infusion rate is the amount of fluid that is delivered per unit of time, usually expressed in mL/hour.
To find the infusion rate, the nurse can use the following formula:
Infusion rate (mL/hour) = Volume (mL) / Time (hour)
In this case, the volume is 150 mL and the time is 90 minutes or 1.5 hours. Plugging these values into the formula, we get:
Infusion rate (mL/hour) = 150 mL / 1.5 hour
Infusion rate (mL/hour) = 100 mL/hour
Therefore, the nurse should program the infusion pump to deliver 100 mL/hour of ganciclovir IV solution.
Correct Answer is ["250"]
Explanation
Total volume= 500mls
Time to infuse= 2hrs
Rate=volume/time
=500/2
=250
Rate is 250mls/hr
