A client receives a prescription for penicillin 5 million units in 100 mL of 0.9% sodium chloride to be infused over 30 minutes. How many mL/hr should the nurse set the infusion pump? (Enter numerical value only.)
The Correct Answer is ["200"]
Total volume to be infused = 100 mL
Convert the infusion time from minutes to hours:
Infusion time (hours) = Infusion time (minutes) / 60 minutes/hour
= 30 minutes / 60 minutes/hour
= 0.5 hours
Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)
= 100 mL / 0.5 hours
= 200 mL/hour

Correct Answer is ["104"]
Explanation
Total volume to be infused = 260 mL
Infusion time in hours = 2.5 hours
Calculate the infusion rate in mL per hour:
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)
= 260 mL / 2.5 hours
= 104 mL/hour
Correct Answer is ["1.8"]
Explanation
Calculation:
Convert the client's weight from pounds to kilograms:
Weight (kg) = Weight (pounds) / 2.2 pounds/kg
= 132 pounds / 2.2 pounds/kg
= 60 kg
Calculate the prescribed dose in milligrams:
Dose (mg) = Prescribed dose (mg/kg) x Client's weight (kg)
= 1.5 mg/kg x 60 kg
= 90 mg
Calculate the volume to administer in mL:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 90 mg / 50 mg/mL
= 1.8 mL
