Multiple Choice

No preservatives, intended for one-time use.

Explanation:
Single-dose vials are designed for one patient and one use, and they are typically prepared without preservatives to avoid preservative-related reactions. Because they’re intended for a single withdrawal, any unused portion is discarded after the first access, which minimizes contamination risk when there’s no preservative involved. This packaging matches the described scenario most directly: no preservatives and intended for one-time use. Ampules are also single-use, but the wording here aligns with the single-dose vial concept, which is specifically identified by being used for a single dose without preservatives.
