Liquid medications administered via injection routes are referred to as.

• A. Ampules
• B. Vials
• C. Self-Contained Systems
• D. Parenteral Medications

Answer: (D)

The concept here is distinguishing medication by route of administration. Liquids given by injection are classified as parenteral medications because “parenteral” means outside the gastrointestinal tract. This category covers injections and infusions delivered by IV, IM, subcutaneous, intraosseous, and similar routes, and these medications must be sterile and suitable for injection.

Ampules and vials are packaging formats for sterile solutions or powders; they describe containers rather than the route or class of the medication. Self-contained systems refer to delivery devices or systems, not the medication type. So the term that correctly describes liquids administered by injection is parenteral medications.
