A client is to receive furosemide 60 mg IV every 12 hours. The medication is available in a concentration of 10 mg/mL, and based on the manufacturer's recommendations, the nurse plans to administer the dosage over 20 minutes. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["18"]
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.

Correct Answer is ["83"]
Explanation
The nurse should set the infusion pump to deliver the entire 2 liters (2000 mL) over the course of 24 hours.
Therefore, the IV pump should be set to deliver:
Rate(mL/hr) = Totalvolume(mL) / Time(hr) = 2000mL / 24hr
After performing the calculation, we find that the rate equals 83.33 mL/hr.
So, the nurse should set the infusion pump to deliver 83 mL/hr (rounded to the nearest whole number).
This is because 83 mL of the solution contains the prescribed dose of penicillin G every hour.
Correct Answer is ["42"]
Explanation
Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:
1. Volume of azithromycin solution:
Volume = 500 mL (given)
2. Infusion duration:
Duration = 2 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 (500 mL) over the specified duration (2 hours).
Steps:
a. Convert infusion duration from hours to minutes:
Duration (minutes) = Duration (hours) x Minutes per hour
Duration (minutes) = 2 hours * 60 minutes/hour
Duration (minutes) = 120 minutes
b. Calculate the total number of drops to be infused:
Total drops = Volume (mL) x Rate (gtt/mL)
Total drops = 500 mL * 10 gtt/mL
Total drops = 5,000 drops
c. Calculate the infusion rate (gtt/min):
Infusion rate (gtt/min) = Total drops / Duration (minutes)
Infusion rate (gtt/min) = 5,000 drops / 120 minutes
Infusion rate (gtt/min) = 41.67 gtt/min (round to nearest whole number as requested)
Therefore, the nurse should regulate the infusion at approximately 42 gtt/min.
