question 27

a pharmacy technician should use a filter needle for which of the following tasks?

to draw up a viscous liquid
to draw fluid from a single-dose vial (sdv)
to draw up liquid from an ampule
to reconstitute a powdered drug

Explanation:

Identify the purpose of a filter needle

Using the Filter Needle Use knowledge point
A filter needle contains a small built-in filter (typically 5 microns) designed to prevent solid particulates, such as glass shards or undissolved powder, from being drawn into a syringe or injected into a patient.

Evaluate the clinical scenarios

Using the Ampule Drawing Technique knowledge point

• To draw up a viscous liquid: Requires a larger bore (smaller gauge) needle, not a filter needle.
• To draw fluid from a single-dose vial (SDV): Typically uses a standard regular needle.
• To draw up liquid from an ampule: Breaking a glass ampule introduces microscopic glass particles into the solution. A filter needle is mandatory to filter out these glass fragments.
• To reconstitute a powdered drug: Uses a standard needle to transfer diluent into the vial.

Answer:

• To draw up a viscous liquid
• To draw fluid from a single-dose vial (SDV)
• To draw up liquid from an ampule (Correct answer)
• To reconstitute a powdered drug
