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 ["2.4"]

Explanation

The vial contains 500 mcg (or 0.5 mg) of digoxin in 2 mL.

This means that each mL contains 0.25 mg of the medication (0.5 mg / 2 mL = 0.25 mg/mL).

The nurse needs to administer 0.6 mg of the medication. To find out how many mL this is, we divide the dose by the concentration:

VolumeinmL = 0.25mg/mL 0.6mg / 0.25mg/mL = 2.4mL

If rounding is required to the nearest tenth, the nurse should administer 2.4 mL of the medication.

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.
