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).

Answer and Explanation

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 ["0.25"]

Explanation

Here's how to calculate the volume (mL) the nurse should administer for somatropin:

1. We know the following:

Prescribed dose: 1.25 mg somatropin (given)

Concentration after reconstitution: 5 mg/mL (given)

2. We need to find the volume (mL) to administer for the prescribed dose (1.25 mg) considering the concentration (5 mg/mL) of the reconstituted solution.

Volume to administer (mL): Dose (mg) / Concentration (mg/mL)

Volume to administer (mL): 1.25 mg / 5 mg/mL

Volume to administer (mL) = 0.25 mL (round to nearest hundredth)

Therefore, the nurse should administer 0.25 mL of the reconstituted somatropin solution subcutaneously.

Correct Answer is ["3600"]

Explanation

Here's how to calculate the maximum daily dose of acetaminophen for the child:

Calculate the maximum dose per administration:

Maximum dose per kg per administration = 15 mg/kg (given)

Child's weight = 40 kg (given)

Since this is a PRN medication (given as needed), we will calculate the maximum dose per administration based on the prescribed dosage.

Maximum dose per administration = 15 mg/kg/dose * 40 kg

Maximum dose per administration = 600 mg (round to nearest whole number)

Calculate the number of administrations in a 24-hour period (maximum):

Frequency: Every 4 to 6 hours PRN (given)

Since this is a PRN medication, we will assume the maximum frequency (every 4 hours) for calculating the maximum daily dose.

Number of administrations (maximum) = 24 hours / Frequency (hours/administration)

Number of administrations (maximum) = 24 hours / 4 hours/administration

Number of administrations (maximum) = 6 administrations

Calculate the maximum daily dose:

Maximum daily dose = Maximum dose per administration x Number of administrations (maximum)

Maximum daily dose = 600 mg/administration * 6 administrations

Maximum daily dose = 3600 mg

Therefore, the maximum daily dose the nurse should administer is 3600 mg.
