The healthcare provider prescribes ganciclovir 375 mg IV every 12 hour to infuse over 90 minutes. The pharmacy delivers ganciclovir 375 mg in a 150 mL IV bag. How many drops/minute should the nurse regulate the gravity infusion using a drip chamber that delivers 10 drops/mL? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["17"]
Let’s calculate the solution step by step:
Calculate the Total Drops in the IV Bag:
The total number of drops in the IV bag can be calculated using the formula:
Total drops = Volume in mL × Drops per mL
Substituting the given values:
Total drops = 150mL × 10drops/mL = 1500drops
Calculate the Rate in Drops/Minute:
The rate in drops per minute can be calculated using the formula:
Rate in drops/minute = Total drops / Time in minutes
Substituting the given values:
Rate in drops/minute = 1500drops/90minutes ≈ 16.67drops/minute
Since the problem asks for the rate to be rounded to the nearest whole number if necessary, the final rate is 17 drops/minute.

Correct Answer is ["100"]
Explanation
The medication is to be administered over 30 minutes,
so if we want to find out the rate in mL/hour,
we need to double the total volume because there are 60 minutes in an hour.
Therefore, the infusion pump should be set to deliver
50mL/30minutes × 60minutes / hour = 100mL/hour
So, the answer is 100. The nurse should program the infusion pump to deliver 100 mL/hour
Correct Answer is ["0.5"]
Explanation
Here's how to calculate the volume of heparin the nurse should administer:
1. Heparin dose: 5,000 units (given)
2. Heparin concentration: 10,000 units/mL (given on the vial label)
We need to find the volume (mL) containing the prescribed dose (5,000 units) of heparin.
Calculation:
Volume to administer (mL) = Dose (units) / Concentration (units/mL)
Volume to administer (mL) = 5,000 units / 10,000 units/mL
Volume to administer (mL) = 0.5 mL (round to nearest tenth as requested)
Therefore, the nurse should administer 0.5 mL of heparin.
