question 115

a pharmacy technician should identify that a luer-lock syringe differs from a luer-slip syringe in which of the following ways?

a luer-slip syringe is designed for higher pressure injections.

a luer-lock syringe has a threaded tip that locks onto the needle hub to prevent accidental disconnection.

a luer-lock syringe cannot be used with filter needles.

a luer-lock syringe is used only for oral medications.

Explanation:

Compare syringe tip designs

Using the Compounding Equipment knowledge point, we evaluate the structural differences between syringe tips. A luer-lock syringe features a threaded, twist-on tip that securely locks the needle hub in place. In contrast, a luer-slip syringe relies on friction to hold the needle hub, which can slip off under high pressure.

Evaluate the given options

• Option 1: Incorrect. Luer-slip syringes are prone to slipping off under high pressure; luer-lock is designed for high-pressure connections.
• Option 2: Correct. The threaded tip of a luer-lock syringe securely locks the needle hub to prevent accidental disconnection.
• Option 3: Incorrect. Luer-lock syringes can be used with filter needles.
• Option 4: Incorrect. Oral syringes (which lack a luer connection entirely to prevent accidental IV administration) are used for oral medications.

Answer:

• A luer-slip syringe is designed for higher pressure injections.
• A luer-lock syringe has a threaded tip that locks onto the needle hub to prevent accidental disconnection. (Correct answer)
• A luer-lock syringe cannot be used with filter needles.
• A luer-lock syringe is used only for oral medications.
