a pharmacy technician should identify that which of the following needle gauges has the largest lumen?

18
19
16
21

Explanation:

Identify the critical site of a syringe

Using the Syringe Critical Sites knowledge point

• Critical sites are areas of compounding equipment that must never be touched or obstructed to prevent contamination of sterile products.
• The plunger of a syringe (specifically the plunger piston/shaft that enters the barrel) is a critical site because touching it introduces contaminants that are drawn directly into the sterile fluid path when the plunger is moved.
• The syringe flange and the outer syringe barrel are non-critical sites because they do not come into direct contact with the sterile product. The needle cap is a protective cover and not a critical site of the syringe itself.

Determine the needle gauge with the largest lumen

• Needle gauge numbers have an inverse relationship with the size of the lumen (the inner bore/opening of the needle).
• A smaller gauge number indicates a larger lumen diameter.
• Comparing the given options: 18, 19, 16, and 21.
• The smallest gauge number is 16, which corresponds to the largest lumen diameter among the choices.

Answer:

Question 1

• Syringe flange
• Syringe plunger (Correct answer)
• Needle cap
• Syringe barrel

Question 2

• 18
• 19
• 16 (Correct answer)
• 21
