Intradermal vaccine administration requires the needle to be inserted at approximately what angle?
Answer: 10–15 degrees
Intradermal injections are given at a 10–15 degree angle, nearly parallel to the skin surface, to deposit vaccine within the dermis.
Which characteristic confirms a correctly placed intradermal injection?
Answer: Formation of a pale wheal (bleb) at the injection site
A pale raised wheal (bleb) appearing under the skin confirms the vaccine was deposited correctly within the dermis.
When administering vaccines to a patient who weighs more than 130 kg (obese adult), what needle length adjustment is recommended for deltoid IM injection?
Answer: Use a 1.5-inch needle
For adults weighing more than 130 kg, a 1.5-inch needle is recommended to ensure the vaccine reaches deltoid muscle through increased subcutaneous tissue.
Which of the following is the correct technique for stretching skin during an IM deltoid injection in an adult?
Answer: Spread the skin taut at the injection site
For IM injections, the skin should be spread taut (not bunched) to allow the needle to penetrate cleanly into the muscle.
Oral polio vaccine (OPV) is no longer used in the United States. If a patient from another country received OPV, how should their immunization history be recorded?
Answer: OPV doses count as valid polio vaccine doses toward U.S. schedules
OPV doses received outside the U.S. are counted as valid polio immunization doses when evaluating a patient's vaccination history.
After preparing a vaccine injection, air bubbles are present in the syringe. What is the recommended action?
Answer: Expel air bubbles before administration to ensure accurate dosage
Air bubbles should be expelled from the syringe before injection to ensure the patient receives the full intended vaccine dose.
A clinician is giving Gardasil 9 (HPV vaccine) to a 16-year-old. Which site and route should be used?
