Question 1 of 5
What is the inheritance pattern of complete androgen insensitivity syndrome?
Correct Answer: D
Rationale: Complete androgen insensitivity syndrome (CAIS) is caused by mutations in the AR gene on the X chromosome, following an X-linked recessive pattern (
Choice
D). Phenotypic females (46,XY) inherit a mutated X from carrier mothers, with males unaffected as they have one X. Autosomal dominant (
Choice
A) and recessive (
Choice
B) don’t apply to X-linked traits. Mitochondrial (
Choice
C) involves maternal transmission, unrelated here. X-linked recessive fits CAIS’s genetics.
Question 2 of 5
An 11-year-old girl with systemic juvenile rheumatoid arthritis appears with fever, lymphadenopathy, and hepatosplenomegaly. The blood test reveals anemia, leukopenia, and thrombocytopenia. This is most likely due to:
Correct Answer: B
Rationale: Macrophage activation syndrome is a severe complication of systemic JIA, marked by fever, organomegaly, and cytopenias from hemophagocytosis (EULAR criteria). Viral syndrome lacks specificity, hemolytic anemia doesn’t fit all findings, spleen failure is unclear, and DIC requires coagulopathy evidence.
Question 3 of 5
Phosphorus moves into the intracellular space resulting in hypophosphatemia in the following condition:
Correct Answer: C
Rationale: Respiratory alkalosis shifts phosphorus intracellularly due to alkalemia, lowering serum levels (Up
ToDate). Acidosis (A,
D) shifts it out, and B, E have minimal effect.
Question 4 of 5
Gonadoblastoma may occur in the following condition:
Correct Answer: B
Rationale: Turner syndrome with Y-chromosome material raises gonadoblastoma risk due to dysgenetic gonads (NOR
D). Other conditions (A, C-E) lack this link.
Question 5 of 5
A child appears with metabolic acidosis. Basic laboratory tests should include all of the following except:
Correct Answer: D
Rationale: Liver enzymes aren’t routine for initial metabolic acidosis workup; A-C, E assess cause and severity (AAP).
