Question 1 of 5
The staging of pubertal changes differs between both genders. The onset of puberty is marked by pubarche and gonadarche. Of the following, the first normal event of puberbertal maturation in boys is
Correct Answer: A
Rationale: Testicular enlargement (gonadarche) is the first sign of puberty in boys, typically at 11-12 years, preceding pubic hair (B), scrotal changes (C), voice deepening (D), and axillary hair (E).
Question 2 of 5
You are examining a 5-day-old neonate with ambiguous genitalia; there are no palpable gonads in the inguinal or genital area; the blood pressure is normal according to the age. Of the following, the NEXT step in the management of this neonate is
Correct Answer: B
Rationale: Chromosomal study (karyotype) is the next step to determine genetic sex in ambiguous genitalia, guiding further evaluation. Imaging (A) and hormone tests (C, D, E) follow based on karyotype results.
Question 3 of 5
Renal osteodystrophy is usually due to secondary hyperparathyroidism. Of the following, the treatment incorrectly matched with the condition is
Correct Answer: A
Rationale: Renal osteodystrophy is usually due to secondary hyperparathyroidism. Alendronate sodium is used in adult osteoporosis, not renal osteodystrophy, which requires phosphate binders or vitamin D analogs.
Question 4 of 5

Correct Answer: D
Rationale: Metabolic disorders in neonates typically present with lethargy, poor tone, poor feeding, and seizures due to metabolic derangements. Hyperthermia is less characteristic, as these infants often have hypothermia from energy failure, making it the exception.
Question 5 of 5
Renal tubular dysfunction in galactosemia may be evidenced by a
Correct Answer: C
Rationale: Galactosemia’s renal tubular dysfunction causes a normal-anion-gap hyperchloremic metabolic acidosis due to impaired bicarbonate reabsorption, consistent with proximal tubulopathy.
