A physician ordered amoxicillin 250 mg tid for 10 days. How many milliliters of amoxicillin oral ...

150 mL

Rationale: 150 mL must be dispensed since the patient must take 250 mg three times per day for 10 days. 250 mg is contained in a 1-teaspoon (5-mL) dose. Therefore, (5 mL)(3 times/day)(10days) = 150 mL.

Emulsions

Rationale: Emulsions can be compounded by either using the continental (dry gum) method, the wet gum method, or the beaker method. The dry gum method prepares the primary emulsion from oil, water, and a hydrocolloid or gum type emulsifier (usually acacia). It is formed from 4 parts oil, 2 parts water, and 1 part emulsifier.
