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 ["1.1"]
Explanation
Determine the desired dosage:
The nurse needs to administer 250 mg of cefazolin.
Determine the volume per dose:
The concentration of the reconstituted cefazolin solution is 225 mg/mL.
The nurse needs to administer 250 mg per dose.
To find the volume per dose:
225 mg / 1 mL = 250 mg / x mL
Cross-multiplying gives us:
225x = 250
Dividing both sides by 225, we get:
x = 1.111 mL
Round the answer to the nearest tenth:
Rounding 1.111 to the nearest tenth gives us 1.1 mL.
Correct Answer is ["7.5"]
Explanation
Determine the desired dosage:
The nurse needs to administer 0.375 mg of digoxin.
Determine the volume per dose:
The digoxin elixir contains 0.05 mg per 1 mL.
The nurse needs to administer 0.375 mg per dose.
To find the volume per dose, we can set up a proportion:
0.05 mg / 1 mL = 0.375 mg / x mL
Cross-multiplying gives us:
0.05x = 0.375
Dividing both sides by 0.05, we get:
x = 7.5 mL
