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"]
- 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 ["18"]
Explanation
To determine the infusion rate, we'll use the following formula:
Infusion rate (mL/hr) = Desired dose (units/hr) / Concentration of heparin (units/mL)
First, calculate the concentration of heparin in the IV bag:
- 20,000 units / 250 mL = 80 units/mL
Then, plug the values into the formula:
- Infusion rate = 1,400 units/hr / 80 units/mL = 17.5 mL/hr
Therefore, the nurse should program the infusion pump to deliver 18 mL/hr (rounded to the nearest whole number).
Correct Answer is ["1.2"]
Explanation
- Calculate the amount of solution needed to provide 150 mg of hydrocortisone sodium succinate
- Use the formula: D/H x Q = X, where D is the desired dose, H is the dose on hand, Q is the quantity on hand, and X is the amount to administer
- Plug in the values: 150/250 x 2 = 1.2
- Round to the nearest tenth: 1.2 mL
- Administer 1.2 mL of the reconstituted solution intravenously STAT
