If an order is written for metoclopramide 10 mg three times a day, how much in milliliters should the resident receive if the solution on hand is 5 mg/5 ml?

To determine the correct amount in milliliters that the resident should receive when prescribed metoclopramide 10 mg three times a day, we start with the concentration of the solution available, which is 5 mg in 5 ml.

This concentration can be simplified to understand how much liquid corresponds to each milligram of the medication. Here, 5 mg corresponds to 5 ml, hence 1 mg would correspond to 1 ml of the solution (because 5 ml / 5 mg = 1 ml per mg).

For a prescribed dose of 10 mg, you can calculate the volume needed by multiplying the number of milligrams by the conversion factor:

10 mg x 1 ml/mg = 10 ml.

Thus, the resident should receive 10 ml of the metoclopramide solution to adhere to the prescription of 10 mg. This shows understanding of dosage calculation based on the concentration of the medication, ensuring the resident receives the proper dose in a safe manner.
