Because young children cannot express themselves well, the nurse uses the therapeutic intervention that allows children to act out their feelings, which is:

Correct Answer: B

Rationale: Play therapy (B) lets young children express feelings through play. Art (A), music (C), and bibliotherapy (D) are less suited for preverbal kids. Document: 'Play therapy allows a young child to act out… concerns.'

Correct Answer: A

Rationale: Infants’ short, wide, straight eustachian tubes (A) allow bacteria easy middle ear access. Sucking (B), position (C), and bronchitis (D) are less causative. Document: 'An infant’s eustachian tubes are short, wide, and straight.'

Correct Answer: A

Rationale: Acute rheumatic fever (ARF) is a complication of group A Streptococcus infection, diagnosed by the Jones criteria. Arthritis (Choice A) is the most common presenting feature, occurring in 60-75% of cases, typically as migratory polyarthritis affecting large joints. Carditis (Choice B) occurs in 50-60% of cases and is a major criterion, but it’s less frequent at initial presentation than arthritis. Erythema marginatum (Choice C) and subcutaneous nodules (Choice D) are rare, occurring in <5% and <1% of cases, respectively, and are not the most common presenting features. Arthritis’s high prevalence and early onset make it the correct answer.

Correct Answer: C

Rationale: Lissencephaly, a smooth brain appearance, results from defective neuronal migration (Choice C) during weeks 8-14 of gestation, impairing cortical layer formation. Myelination (Choice A) occurs later. Neuronal and glial proliferation (Choice B) precedes migration. Neuronal organisation (Choice D) follows migration. Migration defects cause lissencephaly’s hallmark.

Correct Answer: C

Rationale: Choice C is false; an emergency court order is indicated if parents refuse hospitalization in suspected abuse with safety risks (AAP). All other statements (A, B, D, E) are true per abuse protocols.
