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.)

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.
