Which term refers to a solid whose particles are mixed with, but not dissolved in, a liquid?

• A. Gtt.
• B. Lozenge
• C. Suspension
• D. Gavage

Answer: (C)

A suspension is a solid dispersed in a liquid but not dissolved. The solid particles stay mixed for a time but will settle to the bottom if left undisturbed, and they are usually cloudy or opaque. Because they aren’t dissolved, you typically shake the mixture before dosing to redistribute the particles. This contrasts with a solution, where the solid dissolves and the liquid remains clear. The other terms don’t describe this concept: a lozenge is a solid designed to dissolve in the mouth; a gtt. is a drop; gavage refers to delivering a substance directly into the stomach. Therefore, the correct term for a solid mixed with a liquid but not dissolved is a suspension.
