A client receives a prescription for IV ciprofloxacin 400 mg every 12 hours, which is to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (DSW) 200 mL. How many mL/hr should the nurse program the infusion pump to deliver? (Enter numerical value only.)
The Correct Answer is ["200"]
Here's why:
The entire dose (400 mg) is contained within the 200 mL bag.
The information doesn't suggest the bag needs to be emptied completely during the infusion.
Our goal is to deliver the 400 mg dose over the 1-hour infusion period.
Therefore, the nurse should program the infusion pump to deliver the entire volume of the bag (200 mL) containing the medication over the 1-hour timeframe.
Calculation:
Volume to deliver (mL/hr) = Total volume of bag (mL) / Infusion time (hours)
Volume to deliver (mL/hr) = 200 mL / 1 hour
Volume to deliver (mL/hr) = 200 mL/hr
Therefore, the nurse should program the infusion pump to deliver 200 mL/hr.

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.
Correct Answer is ["120"]
Explanation
Here's how to calculate the rate (mL/hour) for the infusion pump to deliver lidocaine 4 mg/minute:
1. Lidocaine concentration:
The medication bag contains 1 gram of lidocaine in 500 mL of dextrose 5% in water.
Convert grams to milligrams: 1 gram = 1000 milligrams
Lidocaine concentration (mg/mL) = Total lidocaine (mg) / Volume (mL)
Lidocaine concentration (mg/mL) = 1000 mg / 500 mL
Lidocaine concentration (mg/mL) = 2 mg/mL (round to nearest whole number)
2. Prescribed lidocaine dose: 4 mg/minute (given)
3. We need to find the volume delivered per hour (mL/hour) to achieve the prescribed lidocaine dose (4 mg/minute) considering the concentration (2 mg/mL) in the bag.
Infusion rate (mL/hour) = Dose (mg/minute) x Minutes per hour / Concentration (mg/mL)
However, there's a mismatch in units between dose (mg/minute) and concentration (mg/mL).
To address this, we can convert the infusion duration (minutes) to hours to match the concentration units (mg/mL).
Conversion factor: 60 minutes/hour
Infusion rate (mL/hour) = Dose (mg/minute) x (60 minutes/hour) / Concentration (mg/mL)
Infusion rate (mL/hour) = 4 mg/minute * 60 minutes/hour / 2 mg/mL
Infusion rate (mL/hour) = 120 mL/hour (round to nearest whole number)
Therefore, the nurse should program the infusion pump to deliver approximately 120 mL/hour.
