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.

Correct Answer is ["4.8"]
Explanation
The vial is labeled as “100 mg per 4 mL.”
This means that each mL contains 25 mg of the medication (100 mg / 4 mL = 25 mg/mL).
The nurse needs to administer 120 mg of the medication.
To find out how many mL this is, we divide the dose by the concentration:
VolumeinmL = 120mg / 25mg/mL = 4.8mL
If rounding is required to the nearest tenth, the nurse should administer 4.8 mL of the medication.
Correct Answer is ["0.8"]
Explanation
Here's how to calculate the volume the nurse should administer:
Concentration of epoetin alfa: 10,000 units/mL (given on the vial label)
Prescribed dose: 8,200 units
We need to find the volume (in mL) that contains the prescribed dose (8,200 units) of epoetin alfa.
Dosage calculation:
Volume to administer (mL) = Dose (units) / Concentration (units/mL)
Volume to administer (mL) = 8,200 units / 10,000 units/mL
Volume to administer (mL) = 0.82 mL (round to nearest tenth as requested)
Therefore, the nurse should administer 0.8 mL.
