A client who weighs 154 pounds receives a prescription for epoetin alfa 50 units/kg subcutaneously 3 times a week. The medication is available in 2000 units/mL vial. How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.8 mL"]
- Convert the client's weight to kilograms: 154 pounds / 2.2 = 70 kg - Calculate the dose in units: 50 units/kg x 70 kg = 3500 units
- Calculate the volume in mL: 3500 units / 2000 units/mL = 1.75 mL
- Round to the nearest tenth: 1.8 mL
- The nurse should administer 1.8 mL with each dose.

Correct Answer is ["15 mL"]
Explanation
- Calculate the daily dose of amoxicillin for the child: 80 mg/kg/day x 66 pounds / 2.2 pounds/kg = 2400 mg/day
- Divide the daily dose by the number of doses per day: 2400 mg/day / 2 doses/day = 1200 mg/dose
- Convert the dose from mg to mL using the label information: 1200 mg/dose x 5 mL/400 mg = 15 mL/dose
- The nurse should administer 15 mL of amoxicillin with each dose.
Correct Answer is ["200 mL\/hour"]
Explanation
- To calculate the infusion rate, divide the volume of the solution by the infusion time in hours: 500 mg/100 mL / 0.5 hour = 200 mL/hour
- The nurse should program the infusion pump to deliver 200 mL/hour of daptomycin solution
- The answer is 200 (mL/hour)
