he nurse is preparing to administer methylprednisolone 40 mg IV. The medication vial is labeled, "125 mg per 2 mL. How many mLs of medication should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest hundredth

Answer and Explanation

The Correct Answer is ["0.64"]

Here's the calculation:

Prescribed dose: 40 mg methylprednisolone

Medication vial concentration: 125 mg per 2 mL (given on the vial label)

We need to find the volume (mL) containing the prescribed dose (40 mg) of methylprednisolone.

Calculation:

Concentration adjustment: The concentration is given in mg per 2 mL. To calculate the medication needed for the 40 mg dose, we need the concentration in mg/mL.

Concentration (mg/mL) = Total mg / Volume (mL)

Concentration (mg/mL) = 125 mg / 2 mL

Concentration (mg/mL) = 62.5 mg/mL

Volume to administer:

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

Volume to administer (mL) = 40 mg / 62.5 mg/mL

Volume to administer (mL) = 0.64 mL (round to nearest hundredth)

Therefore, the nurse should administer 0.64 mL of methylprednisolone.

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 ["5"]

Explanation

Here's how to calculate the volume of medication the nurse should administer on the first day:

1. Convert child's weight to kilograms (kg):

We know 1 kg = 2.205 pounds.

Child weight (kg) = 44 pounds / 2.205 pounds/kg = 20 kg (round to nearest whole number for this calculation).

2. Calculate the total azithromycin medication for the first day (mg):

Prescribed dosage (mg/kg): 10 mg/kg

Child weight (kg): 20 kg (rounded value from step 1)

Total medication on day 1 (mg) = Dosage (mg/kg) x Client weight (kg)

Total medication on day 1 (mg) = 10 mg/kg x 20 kg = 200 mg

3. Determine the volume (mL) needed based on the medication concentration:

Medication concentration (mg/mL): 200 mg/5 mL (given)

Total medication on day 1 (mg): 200 mg (calculated in step 2)

Volume to administer (mL) = Total medication (mg) / Concentration (mg/mL)

Volume to administer (mL) = 200 mg / 200 mg/5 mL

Volume to administer (mL) = 5 mL

Therefore, the nurse should administer 5 mL of the azithromycin solution on the first day.
