APHA Injection Safety & Infection Control 2

Question 1

What is the maximum recommended injection volume for a single IM injection in the deltoid muscle of an adult?

Accepted Answer

2 mL

Answer

The deltoid muscle can accommodate up to 2 mL per injection; larger volumes should be divided or administered in a larger muscle group such as the vastus lateralis.

Question 2

After withdrawing the needle from a patient using a safety syringe, when should the safety mechanism be activated?

Accepted Answer

Immediately after the needle is withdrawn from the patient

Answer

Safety devices must be activated immediately after needle withdrawal to eliminate the window of exposure to the unsheathed needle.

Question 3

Under OSHA's Bloodborne Pathogens Standard, what must an employer provide to a worker following a needlestick injury?

Accepted Answer

Post-exposure evaluation and follow-up at no cost to the worker

Answer

OSHA's Bloodborne Pathogens Standard requires employers to provide post-exposure evaluation and follow-up at no cost to the employee after a needlestick event.

Question 4

According to current CDC/ACIP guidelines, should a vaccine administrator aspirate (pull back on the plunger) before injecting a vaccine intramuscularly?

Accepted Answer

No, aspiration is not recommended for routine vaccine administration

Answer

CDC and ACIP no longer recommend aspiration before routine IM vaccine injections, as evidence does not support the benefit and it increases patient discomfort.

Question 5

What is the correct skin preparation technique before administering a vaccine injection?

Accepted Answer

Wipe the site with an alcohol swab and allow the skin to dry before injecting

Answer

Alcohol should be applied and allowed to dry completely before injection to ensure effective disinfection and prevent stinging from residual alcohol.
