1. What is the most critical physiologic 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 onset of breathing is the most immediate and critical physiologic change required for the transition to extrauterine life. Factors that interfere with this normal transition increase fetal asphyxia, which is a condition of hypoxemia, hypercapnia, and acidosis. While body temperature maintenance, stabilization of fluid and electrolytes, and closure of fetal shunts in the heart are crucial changes in the transition to extrauterine life, breathing and the exchange of oxygen for carbon dioxide must take precedence as they are essential for newborn survival.

2. The nurse is using a bulb syringe to suction a neonate after delivery. What is an important consideration?

• A. Compress the bulb before insertion.
• B. Clear the mouth and pharynx before the nasal passages.
• C. Use two bulb syringes, one for the mouth and pharynx and one for the nasal passages.
• D. Continue using a bulb syringe until secretions are removed as mechanical suction is contraindicated.

Correct answer: B

Rationale: The correct consideration when using a bulb syringe to suction a neonate after delivery is to clear the mouth and pharynx before the nasal passages to prevent aspiration of amniotic fluid. Compressing the bulb syringe before insertion is important to create suction. Using two bulb syringes is unnecessary, as one is sufficient for both the mouth/pharynx and nasal passages. It is not recommended to continue using a bulb syringe until all secretions are removed; instead, mechanical suction can be employed if more forceful removal of secretions is required.

3. A 2-year-old child has a chronic history of constipation and is brought to the clinic for evaluation. What should the therapeutic plan initially include?

• A. Bowel cleansing
• B. Dietary modification
• C. Structured toilet training
• D. Behavior modification

Correct answer: B

Rationale: Dietary modification is often the first step in managing chronic constipation in children, focusing on increasing fiber and fluid intake. Other interventions like bowel cleansing and toilet training may follow if dietary changes are insufficient.

4. What is the therapeutic intervention that provides the best chance of survival for a child with cirrhosis?

• A. Nutritional support
• B. Liver transplantation
• C. Blood component therapy
• D. Treatment with corticosteroids

Correct answer: B

Rationale: Liver transplantation offers the best chance of survival for children with cirrhosis, especially in advanced stages where the liver can no longer function effectively. Cirrhosis is a late stage of scarring of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism. While nutritional support, blood component therapy, and corticosteroids may be part of the treatment plan to manage symptoms and complications, they do not address the underlying cause of cirrhosis or provide a cure like liver transplantation does.

5. 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.
