Correct Answer is ["0.64"]
Explanation
First, calculate the concentration of methylprednisolone in the vial by dividing the amount of medication by the volume of solution: 125 / 2 = 62.5 mg/mL Next, divide the prescribed dose by the concentration of methylprednisolone: 40 /62.5 =0.64 mL
The answer is 0.64 mL.
Correct Answer is ["75"]
Explanation
-
Identify given information:
- Dose per administration = 15 mL
- Frequency = 2 times per day (every 12 hours)
- Concentration = 12.5 mg per 5 mL
-
Convert mL to mg using the concentration:
- (15 mL × 12.5 mg) ÷ 5 mL = 37.5 mg per dose
-
Calculate the total daily dose:
- 37.5 mg × 2 doses per day = 75 mg
Sothe total daily dose the nurse should administer is 75 mg.
