The healthcare provider prescribes epoetin alfa 8,200 units SUBQ for a client with chronic kidney disease (CKD). The 2 mL multidose vial is labeled, "Each 1 mL of solution contains 10,000 Units of epoetin alfa." How many mL should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth).
The Correct Answer is ["0.8"]
Here's how to calculate the volume the nurse should administer:
Concentration of epoetin alfa: 10,000 units/mL (given on the vial label)
Prescribed dose: 8,200 units
We need to find the volume (in mL) that contains the prescribed dose (8,200 units) of epoetin alfa.
Dosage calculation:
Volume to administer (mL) = Dose (units) / Concentration (units/mL)
Volume to administer (mL) = 8,200 units / 10,000 units/mL
Volume to administer (mL) = 0.82 mL (round to nearest tenth as requested)
Therefore, the nurse should administer 0.8 mL.

Correct Answer is ["0.4"]
Explanation
here's how to calculate the volume (mL) of ketorolac the nurse should administer:
1. Dose of ketorolac to administer:
Dose = 12 mg (given)
2. Concentration of ketorolac in the vial:
Concentration = 30 mg/mL (given)
3. We need to find the volume (mL) containing the prescribed dose (12 mg) considering the concentration (30 mg/mL) in the vial.
Volume to administer (mL): Dose (mg) / Concentration (mg/mL)
Volume to administer (mL): 12 mg / 30 mg/mL
Volume to administer (mL) = 0.4 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 0.4 mL of ketorolac intravenously.
Correct Answer is ["4.8"]
Explanation
The vial is labeled as “100 mg per 4 mL.”
This means that each mL contains 25 mg of the medication (100 mg / 4 mL = 25 mg/mL).
The nurse needs to administer 120 mg of the medication.
To find out how many mL this is, we divide the dose by the concentration:
VolumeinmL = 120mg / 25mg/mL = 4.8mL
If rounding is required to the nearest tenth, the nurse should administer 4.8 mL of the medication.
