1. What disease should be suspected in a 3-day-old infant presenting with abdominal distention, vomiting, and failure to pass meconium?

• A. Pyloric stenosis
• B. Intussusception
• C. Hirschsprung disease
• D. Celiac disease

Correct answer: C

Rationale: Hirschsprung disease should be suspected in a newborn with abdominal distention, vomiting, and failure to pass meconium. This condition arises from a congenital absence of nerve cells in a portion of the colon, leading to severe constipation and intestinal obstruction. Pyloric stenosis typically presents with non-bilious projectile vomiting in the first few weeks of life. Intussusception classically manifests with sudden onset of colicky abdominal pain and currant jelly stools. Celiac disease may present with chronic diarrhea, failure to thrive, and abdominal distention but is less likely in this scenario.

2. What is the most critical physiological change required of newborns at birth?

• A. Transition from fetal to neonatal breathing
• B. Body temperature maintenance
• C. Stabilization of fluid and electrolytes
• D. Closure of fetal shunts in the heart

Correct answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The most critical physiological change required of newborns at birth is the initiation of breathing. This transition is crucial for the newborn to start exchanging oxygen and carbon dioxide outside the womb, marking the beginning of their independent respiratory function. Choices B, C, and D are important aspects of newborn care but are not as immediately critical as the establishment of breathing for oxygenation and removal of carbon dioxide, which is essential for the newborn's survival and adaptation to extrauterine life.

3. What is a classic sign of congenital hypothyroidism in newborns?

• A. Jaundice
• B. Hypothermia
• C. Prolonged jaundice
• D. Excessive crying

Correct answer: C

Rationale: Prolonged jaundice is a classic sign of congenital hypothyroidism in newborns. In congenital hypothyroidism, the thyroid gland does not produce enough thyroid hormones, leading to symptoms like jaundice, poor feeding, constipation, and lethargy. While jaundice itself is a common condition in newborns, the term 'prolonged jaundice' specifically points towards the underlying thyroid issue. Hypothermia and excessive crying are not typically associated with congenital hypothyroidism.

4. According to Piaget, a 6-month-old infant should be in which developmental stage?

• A. Use of reflexes
• B. Primary circular reactions
• C. Secondary circular reactions
• D. Coordination of secondary schemata

Correct answer: C

Rationale: By 6 months, infants are usually in the stage of secondary circular reactions, where they start to intentionally repeat actions that bring pleasure or interesting results.

5. What does the Hib conjugate vaccine protect against?

• A. Bacterial meningitis
• B. Epiglottitis
• C. Bacterial pneumonia
• D. All Correct

Correct answer: D

Rationale: The Hib conjugate vaccine is crucial for protecting children from several severe infections caused by Haemophilus influenzae type b, including bacterial meningitis, epiglottitis, bacterial pneumonia, septic arthritis, and sepsis. Therefore, all the provided options are correct. Bacterial meningitis, epiglottitis, and bacterial pneumonia are serious conditions that the Hib vaccine effectively prevents, making choice D the correct answer. Choices A, B, and C are incorrect when considered individually as the Hib vaccine does not protect against only one specific infection; rather, it provides immunity against multiple diseases caused by Haemophilus influenzae type b.
