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.)
Answer and Explanation

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.

Correct Answer is ["440"]

Explanation

The pharmacy provides a 110 mL premixed solution of pantoprazole to be infused over 15 minutes.

First, let’s find out how many mL should be delivered per minute.

We divide the total volume by the total time in minutes:

RateinmL/min = 110mL /15min ​≈ 7.33mL/min

We need to convert this to mL/hr since we want the rate in mL/hr.

There are 60 minutes in an hour, so:

RateinmL/hr = 7.33mL/min×60 = 440mL/hr

So, the nurse should program the secondary infusion to deliver 440 mL/hr.

Correct Answer is ["18"]

Explanation

Here's how to calculate the infusion rate (mL/hour) for the nurse to administer furosemide 60 mg IV every 12 hours:

1. Furosemide dose per administration:

Dose = 60 mg (given)

2. Dosage frequency (conversion from hours to minutes):

Frequency (minutes) = 12 hours/dose * 60 minutes/hour

Frequency (minutes) = 720 minutes/dose

3. Medication concentration:

Concentration = 10 mg/mL (given)

4. Infusion duration:

Duration = 20 minutes (given)

5. We need to find the total volume (mL) of the medication to be delivered and then convert that volume to a rate per hour (mL/hour).

Steps:

a. Calculate the volume to be infused (mL):

Volume (mL) = Dose (mg) / Concentration (mg/mL)

Volume (mL) = 60 mg / 10 mg/mL

Volume (mL) = 6 mL

b. Convert infusion duration from minutes to hours:

Infusion time (hours) = Infusion time (minutes) / 60 minutes/hour

Infusion time (hours) = 20 minutes / 60 minutes/hour

Infusion time (hours) = 1/3 hour

c. Calculate the infusion rate (mL/hour):

Infusion rate (mL/hour) = Volume (mL) / Infusion time (hours)

Infusion rate (mL/hour) = 6 mL / (1/3 hour)

Infusion rate (mL/hour) = 18 mL/hour

Therefore, the nurse should set the infusion pump to deliver approximately 18 mL/hour.
