Which of the following terms describes a liquid preparation that consists of a mixture of solid particles suspended in a liquid?

The term that accurately describes a liquid preparation containing solid particles that are suspended within a liquid is "suspension." In this type of formulation, the solid particles do not dissolve completely but remain dispersed throughout the liquid medium. This is important because, when administered, a suspension requires shaking or stirring to ensure an even distribution of the particles before use.

A tincture, on the other hand, is an alcoholic extract of a plant or other material, where the active components are dissolved rather than suspended. A solution is a homogeneous mixture in which the solute is completely dissolved in the solvent, meaning no solid particles remain. A suppository is a solid dosage form that is designed to melt or dissolve in the body cavity, rather than being a liquid preparation.

Understanding these distinctions is vital in medication administration, especially when determining the correct method for preparing or presenting medications.
