Pediatric Immunization NCLEX Questions Questions
Question 1 of 5
Class III MHC genes encode for which of the following?
Correct Answer: C
Rationale: Class III MHC genes encode complement components, not T cells or cytokines.
Question 2 of 5
Directly: some recognize nonpeptide phosphorylated lipids and carbohydrates; other recognize antigen that have not been processed
Correct Answer: C
Rationale: TCR γδ can recognize nonpeptide antigens and unprocessed antigens.
Question 3 of 5
The transporter associated with antigen presentation (TAP) the peptides to traverse the membrane bilayer of the endoplasmic reticulum and bind in the empty peptide-binding groove of nascent MHC molecules being synthesized in the endoplasmic reticulum.
Correct Answer: A
Rationale: TAP transports peptides into the ER for loading onto MHC Class I, not Class II.
Question 4 of 5
Protein antigens bound to complement component C3d can bind simultaneously to both and the BCR. This enables the co-receptor complex to cluster and crosslink with the BCR, inducing phosphorylation.
Correct Answer: C
Rationale: C3d binds to CD21 (CR2), linking the co-receptor to the BCR for enhanced signaling.
Question 5 of 5
Phagocytose, bacteriocidal activity, ADCC
Correct Answer: B
Rationale: Neutrophils phagocytose bacteria and perform ADCC.
