How would the nurse advise a parent who states, 'I never know how much food to feed my child'?

Correct Answer: C

Rationale: One tablespoon per year of age (C) is a practical guideline for child portions. Teaspoon limits (A), precise measuring (B), and no snacks (D) are impractical. Document: 'A tablespoon… for each year of age is a good guideline.'

Correct Answer: C

Rationale: Cromolyn sodium (C) is a prophylactic asthma med, used daily regardless of symptoms. Symptom-based (A), timing (B), or stopping (D) misuse it. Document: 'Used as a prophylactic… daily doses are prescribed.'

Correct Answer: C

Rationale: A 7-year-old with recent parental separation shows school refusal, aggression, social withdrawal, and temper outbursts, suggesting major depressive disorder (Choice C). These symptoms—irritability, anhedonia (avoiding friends), and behavioral changes—align with pediatric depression, often triggered by stressors like divorce. ADHD (Choice A) involves chronic inattention/hyperactivity, not acute onset. Conduct disorder (Choice B) lacks the mood and withdrawal elements. Separation anxiety (Choice D) focuses on clinginess, not aggression or anhedonia. Depression best explains the presentation.

Correct Answer: A

Rationale: Down syndrome has a ~50% incidence of congenital heart defects (e.g., AVSD), making an echocardiogram critical pre-anesthesia to assess cardiac risk (AAP guidelines). EKG is less specific for structural issues. Lateral neck x-ray checks atlantoaxial instability, but cardiac evaluation takes precedence. GI studies (D, E) are irrelevant here.

Correct Answer: A

Rationale: Choice A is false; negative cultures don’t exclude TB in children due to low bacterial yield, relying on clinical diagnosis (AAP). Choices B-E are true.
