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
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 (UpToDate). Acidosis (A, D) shifts it out, and B, E have minimal effect.
Question 3 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 (NORD). Other conditions (A, C-E) lack this link.
Question 4 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).
Question 5 of 5
