Question

A nurse is preparing to administer meperidine 75 mg subcutaneous every 4 hr PRN pain. Available is meperidine injection 100 mg/ml. How many ml should the nurse administer per dose?

Answer 1

To determine the amount of meperidine injection that the nurse should administer per dose, we need to calculate the volume of the injection that contains 75 mg of the drug. The nurse should administer 0.75 ml of the meperidine injection per dose.

Step-by-step explanation:

To determine the amount of meperidine injection that the nurse should administer per dose, we need to calculate the volume of the injection that contains 75 mg of the drug. We know that the concentration of the meperidine injection is 100 mg/ml. Therefore, we can use the following formula:

Volume (ml) = Dose (mg) / Concentration (mg/ml)

Plugging in the values, we have:

Volume (ml) = 75 mg / 100 mg/ml

Simplifying the equation, we find:

Volume (ml) = 0.75 ml

Therefore, the nurse should administer 0.75 ml of the meperidine injection per dose.
