Question

A medical assistant is reviewing a prescription for oral liquid medication. The prescription calls for 10 mg of diazepam oral solution. The available diazepam oral solution is 5 milligrams/mL. How many milliliters of the solution are required for each dose?

Answer 1

To provide a 10 mg dose of diazepam from a solution with a concentration of 5 mg/mL, 2 milliliters of the solution are needed.

Step-by-step explanation:

To determine how many milliliters of the diazepam oral solution are required for each 10 mg dose given the available concentration, we use a simple proportion.

The available diazepam oral solution is 5 milligrams per milliliter (mg/mL). The prescription calls for a 10 mg dose of diazepam. To find out how many milliliters this would be, set up the equation with the known concentration and solve for the required volume:

Dosage required: 10 mg
Concentration available: 5 mg/mL

So, the equation is: (5 mg/mL) x (V mL) = 10 mg, where V is the volume in milliliters needed.
Divide both sides of the equation by 5 mg/mL to solve for V:

V = (10 mg) / (5 mg/mL)
V = 2 mL

Therefore, 2 milliliters of the solution are required to provide a 10 mg dose of diazepam.
