Question 18 :
The nurse is preparing to administer methylprednisolone 40 mg IV. The medication vial is labeled "125 mg per 2 mL." How many mL of medication should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest hundredth.)
Correct Answer: ["0.64mL"]
The nurse should administer 0.64 mL of the medication. This is because 40 mg is the desired dose, and 125 mg/2 mL is the concentration of the medication. To find the concentration in mg per mL, we divide by 2, so it is 62.5 mg/mL. Using the same formula as before, we can solve for V by plugging in the values: V = 40/62.5 = 0.64.
