Rationale: Sterile normal saline is often used as a diluent in parenteral medications. Powder or cocoa butter cannot be used as diluents because they are either solid or semisolid. Alcohol is not used as a diluent because it has its own strong effects on the body, and a diluent essentially must be a stable, pure liquid.
