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 ["2000"]
Explanation
Here's how to calculate the total milligrams of ampicillin the child should receive per day:
Convert child's weight to kilograms:
Weight (kg) = Weight (lbs) / Conversion factor (lbs/kg)
Weight (kg) = 88 lbs / 2.205 lbs/kg
Weight (kg) = 40 kg (round to nearest whole number)
Calculate the total daily dosage:
Daily dosage (mg) = Dose per kg (mg/kg/day) * Weight (kg)
Daily dosage (mg) = 50 mg/kg/day * 40 kg
Daily dosage (mg) = 2000 mg
Therefore, the child should receive 2000 mg of ampicillin per day.
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.
