A nurse is preparing to administer methylprednisolone acetate 60 mg IM weekly. Methylprednisolone acetate suspension for injection 80 mg/mL is available. How many mL should the nurse administer per dose? Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.
The Correct Answer is ["0.75"]
The correct answer and explanation is:
0.75 mL.
To calculate the mL needed, divide the dose (60 mg) by the concentration (80 mg/mL): 60 mg ÷ 80 mg/mL = 0.75 mL
Therefore, the correct answer is 0.75 mL.

Correct Answer is ["0.8"]
Explanation
First, the child's weight needs to be converted from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram.
68 lb ÷ 2.2 = 30.9 kg
Next, the dose of diphenhydramine in mg can be calculated by multiplying the child's weight in kg by the dose in mg/kg.
1.25 mg/kg × 30.9 kg = 38.6 mg
Finally, to calculate the number of mL the nurse should administer, you need to divide the dose of diphenhydramine in mg by the concentration of the diphenhydramine injection in mg/mL.
38.6 mg ÷ 50 mg/mL = 0.8 mL
So, the nurse should administer 0.8 mL of diphenhydramine injection.
