1. In which type of cancer are the urinary excretion of the breakdown products of catecholamines, especially vanillylmandelic acid (VMA) and homovanillic acid (HVA), detected?

• A. Neuroblastoma
• B. Nephroblastoma
• C. Leukemia
• D. Osteosarcoma

Correct answer: A

Rationale: The correct answer is A: Neuroblastoma. Neuroblastoma, a cancer that arises from nerve tissue, is associated with increased levels of catecholamine metabolites, including VMA and HVA, in the urine. Nephroblastoma (Wilms tumor) is a type of kidney cancer and is not typically associated with elevated levels of catecholamine breakdown products. Leukemia is a cancer of the blood and bone marrow and does not lead to increased VMA and HVA excretion in urine. Osteosarcoma is a bone cancer and is not linked to elevated levels of catecholamine metabolites in the urine.

2. With the National Center for Health Statistics criteria, which body mass index (BMI)-for-age percentiles should indicate the patient is at risk for being overweight?

• A. 10th percentile
• B. 75th percentile
• C. 85th percentile
• D. 95th percentile

Correct answer: C

Rationale: A BMI-for-age at the 85th percentile indicates a child is at risk for being overweight, according to the National Center for Health Statistics criteria.

3. What is a priority intervention for an infant with a temporary colostomy for Hirschsprung disease?

• A. Teaching how to irrigate the colostomy
• B. Protecting the skin around the colostomy
• C. Discussing the implications of a colostomy during puberty
• D. Using simple, straightforward language to prepare the child

Correct answer: B

Rationale: Protecting the skin around the colostomy is crucial to prevent irritation and infection, which are common complications in infants with colostomies. Teaching and discussing long-term implications are important but secondary to immediate skin care needs.

4. What is the typical presentation of pyloric stenosis in infants?

• A. Bilious vomiting
• B. Projectile vomiting
• C. Blood in stools
• D. Failure to thrive

Correct answer: B

Rationale: The correct answer is B: Projectile vomiting. Pyloric stenosis in infants typically presents with projectile vomiting, which is forceful and projective in nature. This occurs due to the obstruction at the pylorus, leading to the stomach being unable to empty properly. Choices A, C, and D are incorrect. Bilious vomiting is more commonly associated with intestinal obstruction, blood in stools can occur in conditions such as necrotizing enterocolitis or allergic colitis, and failure to thrive is a nonspecific finding that can be seen in various pediatric conditions.

5. Which condition is characterized by a 'seal-like' barking cough in children?

• A. Croup
• B. Asthma
• C. Bronchitis
• D. Pneumonia

Correct answer: A

Rationale: Croup is the correct answer. Croup is characterized by a 'seal-like' barking cough due to inflammation and narrowing of the upper airways, particularly the larynx and trachea. It is most common in young children and can cause significant respiratory distress, especially at night. Treatment often includes humidified air and corticosteroids. Asthma (choice B) typically presents with wheezing and shortness of breath, not a barking cough. Bronchitis (choice C) is characterized by productive cough with mucus, not a barking cough. Pneumonia (choice D) often presents with fever, productive cough, and chest pain, not a barking cough.
