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 ["100"]
Explanation
Determine the total volume of insulin in the vial:
The vial contains 10 mL of insulin.
Determine the concentration of insulin in the vial:
The insulin concentration is 100 units/mL.
Calculate the total number of units of insulin in the vial:
Total units = Volume (mL) × Concentration (units/mL)
Total units = 10 mL × 100 units/mL
Total units = 1000 units
Determine the number of doses:
Each dose is 10 units.
Number of doses = Total units / Units per dose
Number of doses = 1000 units / 10 units/dose
Number of doses = 100 doses
