Ricci Maternity and Pediatrics NCLEX Question Immunization Questions
Question 1 of 5
Predominant in the primary (early) immune response
Correct Answer: C
Rationale: IgM is the first antibody produced in a primary immune response, before class switching to IgG.
Question 2 of 5
Which of the following uses protein antigens separated by molecular weight using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE)?
Correct Answer: D
Rationale: Western blotting uses SDS-PAGE to separate proteins by molecular weight before antigen detection.
Question 3 of 5
If alternative processing uses the first polyadenylation site, then what type of heavy chain mRNA is derived?
Correct Answer: D
Rationale: Using the first polyadenylation site results in μ (mu) heavy chain mRNA, encoding IgM.
Question 4 of 5
Comparing the arrangement of TCR genes and BCR genes, the chain is analogous to the heavy (H) chain and the chain is analogous to the light (L) chain.
Correct Answer: B
Rationale: In TCRs, the beta (β) chain is analogous to the heavy chain, and the alpha (α) chain is analogous to the light chain.
Question 5 of 5
T cells the potential to express an alternative secreted form like the B-cell antigen receptor. Superantigens can activate T cells antigen processing and presentation.
Correct Answer: D
Rationale: T cells do not secrete receptors and superantigens activate them independently of antigen processing.
