APHA Administration Techniques & Routes 2

Question 1

When administering a vaccine intramuscularly to a 4-month-old infant, which site is preferred?

Accepted Answer

Anterolateral thigh

Answer

The anterolateral thigh (vastus lateralis) is the preferred IM injection site for infants because it has sufficient muscle mass and is easily accessible.

Question 2

For subcutaneous (SC) vaccine injections, the needle is typically inserted at which angle?

Accepted Answer

45 degrees

Answer

SC injections are administered at a 45-degree angle to place vaccine into the subcutaneous tissue layer beneath the skin.

Question 3

A patient is receiving Td vaccine. After aspirating the syringe, no blood appears. What is the current CDC/ACIP recommendation regarding aspiration?

Accepted Answer

Aspiration is no longer recommended for routine IM vaccine administration

Answer

ACIP no longer recommends aspiration for IM vaccine injections because the intended injection sites do not contain large blood vessels.

Question 4

Which vaccine is administered via the intranasal route?

Accepted Answer

Live attenuated influenza vaccine (LAIV)

Answer

LAIV (FluMist) is the only vaccine routinely administered intranasally, delivered as a spray into each nostril.

Question 5

When multiple vaccines are administered at the same visit, what is the recommended approach for injection site selection?

Accepted Answer

Use separate anatomic sites, preferably different limbs

Answer

Each vaccine should be administered at a separate anatomic site, ideally in different limbs, to allow attribution of local reactions to specific vaccines.
