1. 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.

2. The nurse is caring for an adolescent who has just started dialysis. The child always seems angry, hostile, or depressed. The nurse should recognize that this is most likely related to what underlying cause?

• A. Physiologic manifestations of renal disease
• B. The fact that adolescents have few coping mechanisms
• C. Neurologic manifestations that occur with dialysis
• D. Resentment of the control and enforced dependence imposed by dialysis

Correct answer: D

Rationale: Adolescents may feel anger and depression due to the loss of independence and control over their lives, which is imposed by the need for regular dialysis treatments. This reaction is common as they struggle with the restrictions placed on their social and personal lives.

3. What statement best describes Hirschsprung disease?

• A. The colon has an aganglionic segment.
• B. It results in frequent evacuation of solids, liquid, and gas.
• C. The neonate passes excessive amounts of meconium.
• D. It results in excessive peristaltic movements within the gastrointestinal tract.

Correct answer: A

Rationale: Hirschsprung disease is characterized by the absence of ganglion cells in a segment of the colon, leading to a lack of peristalsis and obstruction. The other options do not accurately describe this condition.

4. What is a common cause of acquired aplastic anemia in children?

• A. Deficient diet
• B. Ingestion of drugs such as chloramphenicol or antiepileptics
• C. Congenital defects
• D. Injury

Correct answer: B

Rationale: The correct answer is B. Acquired aplastic anemia in children is often caused by exposure to certain drugs, such as chloramphenicol or antiepileptics, which can lead to bone marrow failure and a decrease in all types of blood cells. Choices A, C, and D are incorrect because aplastic anemia is not commonly caused by deficient diet, congenital defects, or injury in children.

5. What clinical manifestation(s) is associated with calcium depletion (hypocalcemia)?

• A. Nausea, vomiting
• B. Weakness, fatigue
• C. Muscle hypotonicity
• D. Neuromuscular irritability

Correct answer: D

Rationale: Hypocalcemia can lead to neuromuscular irritability, causing symptoms such as muscle cramps, tetany, or seizures. Other symptoms like nausea, vomiting, and weakness are less specific and can be related to various conditions.
