Question

A nurse is to administer 150 mg of a drug intramuscularly. The label on the multidose vials reads 100 mg/mL. How much would the nurse give?

Answer 1

The nurse would administer 1.5 mL of the drug, since the required dose of 150 mg divided by the concentration of 100 mg/mL equals 1.5 mL.

Step-by-step explanation:

If a nurse needs to administer 150 mg of a drug intramuscularly and the drug is available in multidose vials with a concentration of 100 mg/mL, the amount to be administered can be calculated by dividing the required dose by the concentration of the drug.

Dose required / Concentration = Volume to be administered

In this case, 150 mg divided by 100 mg/mL equals 1.5 mL. Therefore, the nurse would give 1.5 mL of the drug to the patient.
