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 ["0.7"]
Explanation
The nurse should administer 0.7 mL of diphenhydramine.
Here's the calculation:
Medication dosage: 35 mg (diphenhydramine)
Medication concentration: 50 mg/mL (given on the syringe label)
We need to find the volume (mL) containing the prescribed dose (35 mg) of diphenhydramine.
Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)
Volume to administer (mL) = 35 mg / 50 mg/mL
Volume to administer (mL) = 0.7 mL (round to nearest tenth)
Therefore, the nurse should administer 0.7 mL of diphenhydramine
Correct Answer is ["440"]
Explanation
The pharmacy provides a 110 mL premixed solution of pantoprazole to be infused over 15 minutes.
First, let’s find out how many mL should be delivered per minute.
We divide the total volume by the total time in minutes:
RateinmL/min = 110mL /15min ≈ 7.33mL/min
We need to convert this to mL/hr since we want the rate in mL/hr.
There are 60 minutes in an hour, so:
RateinmL/hr = 7.33mL/min×60 = 440mL/hr
So, the nurse should program the secondary infusion to deliver 440 mL/hr.
