What type of needle is specifically used when working with an ampule?

When working with an ampule, a filtered needle is the appropriate choice because it is designed to prevent glass fragments from being drawn into the syringe when the ampule is opened. Ampules are sealed glass containers that can break easily, and when you insert a needle to withdraw the medication, tiny shards of glass may be dislodged. A filtered needle has a built-in filter that captures these particles, ensuring that only the intended medication is administered. This characteristic helps maintain patient safety by reducing the risk of introducing contaminants into the body.

In contrast, a regular needle may not have this filter and would not adequately protect against glass particles. An intravenous needle is typically utilized for direct administration into the bloodstream and may not be suitable for extracting liquid from an ampule. A subcutaneous needle is used for injections into the subcutaneous tissue and does not address the specific precautions needed when using ampules. Thus, the filtered needle is the most suitable option for safe medication extraction from an ampule.
