Pediatric Immunizations NCLEX Questions Questions
Question 1 of 5
Which needle gauge should be used for IM vaccine administration?
Correct Answer: A
Rationale: For intramuscular (IM) vaccine administration, the recommended needle gauge is typically 22-25, depending on the patient’s age, size, and muscle mass (e.g., 22-25 for adults, 23-25 for children). This range ensures adequate penetration into the muscle while minimizing discomfort. Choice B (23-25) is a subset but excludes 22, which is commonly used for adults. Choice C (20-23) and D (18-21) involve larger gauges more suited for thicker fluids (e.g., blood draws) rather than vaccines, which are typically aqueous.
Question 2 of 5
Clients must receive a copy of their immunization record.
Correct Answer: B
Rationale: There is no universal legal requirement that clients *must* receive a copy of their immunization record after every vaccination, though it’s good practice to provide one upon request or as part of standard care (e.g., CDC recommends access). Records are maintained by providers or immunization information systems (IIS), and clients can access them, but ‘must receive’ implies an obligation not typically mandated, making Choice B (False) correct.
Question 3 of 5
An unexpected and undesirable response after an immunization is:
Correct Answer: B
Rationale: An adverse event is a broad term for any unexpected or undesirable health occurrence following immunization, which may or may not be causally related to the vaccine (e.g., fever, anaphylaxis). Choice A (side effect) refers to common, expected reactions (e.g., soreness). Choice C (allergy) and D (hypersensitivity) are specific immune-mediated reactions, subsets of adverse events, but not as encompassing as Choice B, which aligns with public health reporting (e.g., VAERS).
Question 4 of 5
A 10-year-old child has just received his first immunization of influenza vaccine. His lips begin to swell, and he states, 'It feels like my throat is closing shut and my chest is tight when I breathe.' The nurse recognizes these as signs of which of the following?
Correct Answer: B
Rationale: Swelling lips, throat closure sensation, and chest tightness are classic signs of anaphylaxis, a life-threatening allergic reaction (Choice B). This requires immediate epinephrine. Choice A (anxiety) may cause hyperventilation but not swelling. Choice C (local reaction) is limited to the injection site (e.g., redness), and Choice D (common systemic reaction) implies milder, typical responses (e.g., fever), not anaphylaxis.
Question 5 of 5
An 18 year old patient is in the clinic to receive a tetanus vaccine after sustaining a laceration injury. The nurse learns that the patient, who works in a day care center, has not had any vaccines for more than 10 years. Which vaccine will the nurse expect to administer?
Correct Answer: D
Rationale: For an 18-year-old with a laceration and no vaccines for over 10 years, Tdap is recommended. It updates tetanus (Td) and adds pertussis protection, critical for daycare workers due to pertussis risk to infants. Td (Choice C) lacks pertussis, DT/DTaP (Choices A, B) are for children <7 years.
