A nurse l preparing to administer methylprednisolone acetate 60 mg IM weekly. Available is methylprednisolone acetate suspension for injection 80 mg/mL. How many mi should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use trailing zero.)
The Correct Answer is ["0.75"]
Set up the dosage calculation:
Desired dose: 60 mg
Available concentration: 80 mg/mL
We need to find out how many mL will contain 60 mg of methylprednisolone acetate.
Use the formula:
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
Plug in the values and calculate:
Volume (mL) = 60 mg / 80 mg/mL
Volume (mL) = 0.75 mL
Round to the nearest hundredth:
0.75mL

Correct Answer is ["0.9"]
Explanation
Convert the client's weight from pounds to kilograms:
There are 2.205 pounds in 1 kilogram.
99 lb = 99 lb / 2.205 lb/kg = 44.91 kg (rounded to two decimal places).
Determine the total dosage:
The client is prescribed 0.2 mg/kg of morphine.
The client weighs 44.91 kg.
The total dosage is 0.2 mg/kg x 44.91 kg = 8.982 mg.
Determine the volume per dose:
The morphine injection contains 10 mg per 1 mL.
The nurse needs to administer 8.982 mg per dose.
To find the volume per dose:
10 mg / 1 mL = 8.982 mg / x mL
Cross-multiplying gives us:
10x = 8.982
Dividing both sides by 10, we get:
x = 0.8982 mL
Round the answer to the nearest tenth:
Rounding 0.8982 to the nearest tenth gives us 0.9 mL.
