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 ["4.8"]
Explanation
The vial is labeled as “100 mg per 4 mL.”
This means that each mL contains 25 mg of the medication (100 mg / 4 mL = 25 mg/mL).
The nurse needs to administer 120 mg of the medication.
To find out how many mL this is, we divide the dose by the concentration:
VolumeinmL = 120mg / 25mg/mL = 4.8mL
If rounding is required to the nearest tenth, the nurse should administer 4.8 mL of the medication.
Correct Answer is ["0.4"]
Explanation
here's how to calculate the volume (mL) of ketorolac the nurse should administer:
1. Dose of ketorolac to administer:
Dose = 12 mg (given)
2. Concentration of ketorolac in the vial:
Concentration = 30 mg/mL (given)
3. We need to find the volume (mL) containing the prescribed dose (12 mg) considering the concentration (30 mg/mL) in the vial.
Volume to administer (mL): Dose (mg) / Concentration (mg/mL)
Volume to administer (mL): 12 mg / 30 mg/mL
Volume to administer (mL) = 0.4 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 0.4 mL of ketorolac intravenously.
