Question

A client states he is experiencing a great deal of pain. He has meperidine (Demerol) 30 mg IV prescribed. The available meperidine is labeled 50 mg/mL. How many mL will you administer? (Place your answer in decimal not fraction and place only the numerical value in the space provided.)

Answer 1

To administer the prescribed 30 mg dose of meperidine with a concentration of 50 mg/mL, the nurse would administer 0.6 mL of the solution.

Step-by-step explanation:

To administer the correct dose of meperidine (Demerol), we need to calculate the volume (mL) needed for the prescribed 30 mg dose when the available concentration is 50 mg/mL. The calculation to determine the volume to administer is as follows:

Dose prescribed: 30 mg
Concentration available: 50 mg/mL
Volume to administer (V) = Dose prescribed / Concentration available
Volume to administer (V) = 30 mg / 50 mg/mL

By performing the calculation, we get:

Volume to administer (V) = 0.6 mL

Therefore, the nurse would administer 0.6 mL of the meperidine solution.
