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 ["0.5"]

Explanation

Here's how to calculate the volume of heparin the nurse should administer:

1. Heparin dose: 5,000 units (given)

2. Heparin concentration: 10,000 units/mL (given on the vial label)

We need to find the volume (mL) containing the prescribed dose (5,000 units) of heparin.

Calculation:

Volume to administer (mL) = Dose (units) / Concentration (units/mL)

Volume to administer (mL) = 5,000 units / 10,000 units/mL

Volume to administer (mL) = 0.5 mL (round to nearest tenth as requested)

Therefore, the nurse should administer 0.5 mL of heparin.

Correct Answer is ["21"]

Explanation

Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:

1. We know:

Total volume of D5W solution: 2 L (liters)

Infusion time: 24 hours

IV administration set gtt/mL: 15 gtt/mL

2. We need to find the infusion rate in gtt/min.

Steps:

a. Convert liters to milliliters (mL) for better calculation:

1 liter = 1000 mL

Total volume (mL) = 2 L * 1000 mL/L

Total volume (mL) = 2000 mL

b. Convert infusion time from hours to minutes:

Infusion time (minutes) = Infusion time (hours) x Minutes per hour

Infusion time (minutes) = 24 hours * 60 minutes/hour

Infusion time (minutes) = 1440 minutes

c. Calculate the total volume of solution to be infused per minute:

Volume rate (mL/min) = Total volume (mL) / Infusion time (minutes)

Volume rate (mL/min) = 2000 mL / 1440 minutes

Volume rate (mL/min) = 1.389 mL/min (round to nearest hundredth)

d. Finally, calculate the infusion rate in gtt/min:

Infusion rate (gtt/min) = Volume rate (mL/min) x gtt/mL

Infusion rate (gtt/min) = 1.389 mL/min * 15 gtt/mL

Infusion rate (gtt/min) = 20.835 gtt/min (round to nearest whole number as requested)

Therefore, the nurse should regulate the infusion at approximately 21 gtt/min
