Pediatric Immunization NCLEX Questions Questions
Question 1 of 5
Penicillin can form a hapten-carrier conjugate with a self-protein that can then act as an immunogen and generate an immunoglobulin antibody, and can cross-react with a number of other antibiotics. This can complicate the treatment of bacterial infections in these patients because they are unable to take the antibiotics necessary to combat the infection.
Correct Answer: C
Rationale: This describes an IgE-mediated allergic response, where penicillin cross-reacts, causing hypersensitivity.
Question 2 of 5
If alternative processing uses the second polyadenylation site, then what type of heavy chain mRNA is derived?
Correct Answer: C
Rationale: Using the second polyadenylation site results in δ (delta) heavy chain mRNA, encoding IgD.
Question 3 of 5
Which of the following TCR genetic chains contain D-segments, similar to immunoglobulin heavy chains?
Correct Answer: C
Rationale: Beta (β) and delta (δ) chains contain D-segments, similar to immunoglobulin heavy chains.
Question 4 of 5
A TCR complex is comprised of the TCR, CD3 molecules, and which of the following CD3 chains?
Correct Answer: D
Rationale: The TCR complex includes two zeta ζ) chains as part of the CD3 signaling complex.
Question 5 of 5
Class III MHC genes encode for which of the following?
