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.

Explanation
Concentration of penicillin G benzathine: 1,200,000 units/2 mL (given on the syringe label)
Prescribed dose: 1,800,000 units
We need to find the volume (in mL) that delivers the prescribed dose (1,800,000 units) considering the available concentration.
Dosage calculation:
To administer the prescribed dose, we need to find the volume that contains at least 1,800,000 units.
Since the available concentration is 1,200,000 units/2 mL, one prefilled syringe provides 1,200,000 units.
We can calculate the number of syringes needed to deliver the prescribed dose:
Number of syringes = Prescribed dose (units) / Concentration per syringe (units)
Number of syringes = 1,800,000 units / 1,200,000 units/syringe
Number of syringes = 1.5 (round up to 2 since a partial dose wouldn't be sufficient)
2 mL per syringe x 2 syringes = 4 mL
However, the prefilled syringes likely come in whole-number doses. Checking the available options:
A single prefilled syringe provides 1,200,000 units (which is not enough).
Two prefilled syringes would provide a total of 2,400,000 units (more than enough).
Therefore, to ensure at least the prescribed dose is administered, the nurse should administer 3 mL.
This is achieved by using one and a half (rounded up to two) prefilled syringes.

Explanation
You can calculate the number of acyclovir tablets the nurse should administer every 24 hours using the following steps:
Daily Dosage: The medication is prescribed to be given every 6 hours, so to find the total daily dosage, we need to consider how many times it's administered in 24 hours:
Total Daily Doses = 24 hours / Dosage Frequency (every 6 hours)
Total Daily Doses = 24 hours / 6 hours/dose = 4 doses per day
Tablets per Dose: Since the prescribed dose is 800 mg and each tablet is 400 mg, we can find the number of tablets needed per dose:
Tablets per Dose = Prescribed Dose (mg) / Tablet Strength (mg/tablet)
Tablets per Dose = 800 mg / 400 mg/tablet = 2 tablets/dose
Total Tablets per Day: Now that we know the tablets needed per dose (2) and the total daily doses (4), we can find the total number of tablets for 24 hours:
Total Tablets per Day = Tablets per Dose x Total Daily Doses
Total Tablets per Day = 2 tablets/dose * 4 doses/day
Total Tablets per Day = 8 tablets
Therefore, the nurse should administer 8 tablets of acyclovir to the client every 24 hours.
