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
Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:
1. Volume of lactated Ringer's solution:
Volume = 1 liter (given)
Conversion factor: 1 liter = 1000 mL
Volume (mL) = 1 liter * 1000 mL/liter
Volume (mL) = 1000 mL
2. Infusion duration:
Duration = 8 hours (given)
3. IV administration set gtt/mL:
Rate (gtt/mL) = 10 gtt/mL (given)
4. We need to find the rate (gtt/min) at which the solution should infuse to deliver the total volume (1000 mL) over the specified duration (8 hours).
Steps:
a. Convert infusion duration from hours to minutes:
Duration (minutes) = Duration (hours) x Minutes per hour
Duration (minutes) = 8 hours * 60 minutes/hour
Duration (minutes) = 480 minutes
b. Calculate the total number of drops to be infused:
Total drops = Volume (mL) x Rate (gtt/mL)
Total drops = 1000 mL * 10 gtt/mL
Total drops = 10,000 drops
c. Calculate the infusion rate (gtt/min):
Infusion rate (gtt/min) = Total drops / Duration (minutes)
Infusion rate (gtt/min) = 10,000 drops / 480 minutes
Infusion rate (gtt/min) = 20.83 gtt/min (round to nearest whole number as requested)
Therefore, the nurse should regulate the infusion at approximately 21 gtt/min.
Correct Answer is ["0.1"]
Explanation
Here's how to calculate the volume the nurse should administer:
1. Dose of cyanocobalamin (vitamin B12): 100 mcg
2. Concentration of cyanocobalamin in the vial: 1 mg/mL (given on the vial label)
We need to find the volume (in mL) that contains the prescribed dose (100 mcg) of cyanocobalamin.
Calculation:
Volume to administer (mL) = Dose (mcg) / Concentration (mcg/mL)
Note: Since both the medication dose and concentration are given in mcg units, we can directly perform the calculation without converting units.
Volume to administer (mL) = 100 mcg / 1 mg/mL
Conversion:
1 mg is equal to 1000 mcg. Therefore, 1 mg/mL is the same as 1000 mcg/mL.
Volume to administer (mL) = 100 mcg / (1000 mcg/mL)
Volume to administer (mL) = 0.1 mL (round to nearest tenth as requested)
Therefore, the nurse should administer approximately 0.1 mL of the cyanocobalamin injection.
