How many doses of injectable medication are typically contained in an ampoule?

• A. Two
• B. One
• C. Three
• D. Five

Answer: (B)

An ampoule is a small sealed vial that is typically used to contain a sample of a solid or liquid. In medical settings, ampoules are commonly used for storing injectable medications. The design of an ampoule allows for the preservation of the medication from contamination and oxidation.

In most cases, each ampoule is designed to contain a single dose of medication. This is particularly important in pharmaceuticals, as it ensures that the correct potency and dosage are delivered to the patient without any risk of contamination from previous doses. The single-use nature of ampoules makes them ideal for injectable medications that require strict adherence to dosage and sterility.

While it is theoretically possible for an ampoule to contain multiple doses, this is not the standard practice for injectables. Multiple doses would require specific labeling and possibly different types of containers to prevent dosage errors, which ampoules are not designed to accommodate. Therefore, the single-dose characteristic of ampoules is the key reason why they are widely used in healthcare settings for injectable medications.
