1. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:

• A. Increases peripheral vascular resistance
• B. Decreases arterial blood flow away from the heart
• C. It's a common resting position when a child is tachycardic
• D. Increases the workload of the heart

Correct answer: A

Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.

2. What percentage of total body surface area has been burned in a 5-year-old child who experienced partial-thickness burns to his head, anterior chest, and both upper extremities?

• A. 45%
• B. 63%
• C. 72%
• D. 54%

Correct answer: A

Rationale: According to the pediatric rule of nines, the head and neck represent 18%, the anterior chest and abdomen 18%, and each arm 9%. By adding these percentages (18% + 18% + 9% + 9% = 45%), we find that 45% of the total body surface area has been burned in this child.

3. A child of 3 years has been admitted to your pediatric ward. The doctor gave a provisional diagnosis of respiratory tract infection. After careful assessment and history, he gave a final diagnosis of lower respiratory infection. Which of the following signs will confirm the diagnosis?

• A. Cough
• B. Fever
• C. Inability to lie supine
• D. Inability to eat

Correct answer: C

Rationale: Inability to lie supine is a specific sign of lower respiratory infection. This condition can cause discomfort or difficulty in breathing when lying flat, leading to a preference for an upright or semi-upright position. While cough and fever are common symptoms of respiratory infections, the inability to lie supine is more indicative of lower respiratory involvement.

4. During the pediatric assessment process, which scenario would be the LEAST appropriate for the transition phase?

• A. A parent is available to help keep the child calm.
• B. The child is unstable and needs rapid transport.
• C. You determine that the child's condition is stable.
• D. Your transport time is greater than 30 minutes.

Correct answer: B

Rationale: During a pediatric assessment, the transition phase is a critical period where care is handed over from prehospital providers to the hospital team. If the child is unstable and requires rapid transport, it is not appropriate to delay for a transition phase. In such cases, immediate transport to a higher level of care is paramount to ensure the child's safety and well-being. Choice A is appropriate as having a parent present can help keep the child calm during the transition. Choice C is also appropriate as transitioning a stable child allows for a smoother handover. Choice D, while indicating a longer transport time, does not necessarily affect the need for a transition phase as long as the child's condition remains stable.

5. Which of the following is the MOST detrimental effect of gastric distention in infants and children?

• A. Tracheal rupture.
• B. Less effective chest compressions.
• C. Decreased ventilatory volume.
• D. Acute rupture of the diaphragm.

Correct answer: C

Rationale: Gastric distention in infants and children can lead to a decrease in ventilatory volume. This occurs because the distended stomach can limit the movement of the diaphragm, reducing its ability to contract and expand the chest cavity effectively. As a result, the amount of air entering and leaving the lungs is decreased, impacting ventilation. Tracheal rupture, acute rupture of the diaphragm, and less effective chest compressions are not typically associated with gastric distention.
