Pediatric Immunizations NCLEX Questions Questions
Question 1 of 5
Graft vs host disease often accompanies transplantation of?
Correct Answer: C
Rationale: Bone marrow transplantation carries a high risk of GVHD due to the presence of immunocompetent donor T cells.
Question 2 of 5
Defects in Macrophage to kill bacteria that synthesis Catalase; this called?
Correct Answer: A

Question 3 of 5
Matching: Complement deficiency - Recurrent neisserial infection
Correct Answer: A
Rationale: Deficiencies in C5, C6, C7, C8, or C9 impair the membrane attack complex, leading to recurrent Neisseria infections (e.g., meningococcus). Properdin stabilizes the alternative pathway but is less directly linked to neisserial susceptibility compared to terminal complement deficiencies.
Question 4 of 5
Matching: Immunodeficiency - High frequency of autoimmune disorders
Correct Answer: C
Rationale: CVID is associated with a high frequency of autoimmune disorders due to immune dysregulation.
Question 5 of 5
The X-linked lymphoproliferative (XLP) syndrome is classically associated with overwhelming infection with which organism?
