Correct Answer: D

Rationale: When caring for a child with acute laryngotracheobronchitis, the priority action should be to continually assess the respiratory status. This is crucial to detect early signs of respiratory distress, such as worsening stridor or increased work of breathing. Prompt intervention can prevent further deterioration of the child's condition. Initiating measures to reduce fever (Choice A) may be necessary but is not the priority in this situation. Ensuring delivery of humidified oxygen (Choice B) is important for maintaining oxygenation but should follow the assessment of respiratory status. Providing support to reduce apprehension (Choice C) is also important for the child's comfort but is not the priority over assessing and managing respiratory distress.

Correct Answer: D

Rationale: The priority action when caring for a child with acute laryngotracheobronchitis is to continually assess the respiratory status (Option D). Acute laryngotracheobronchitis can potentially lead to respiratory distress, making continuous monitoring crucial to identify early signs of deterioration and intervene promptly. While options A, B, and C are also important aspects of care, they do not take precedence over respiratory assessment in this critical situation. Initiating measures to reduce fever (Option A), ensuring oxygen delivery (Option B), and providing emotional support (Option C) are all significant interventions, but without ongoing assessment of respiratory status, there is a risk of missing potential respiratory deterioration.

Correct Answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. This procedure reveals the absence of ganglion cells in the affected bowel segment, which is a hallmark of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for diagnosing Hirschsprung disease due to the risk of not accurately reaching the affected segment. Multiple saline enemas (Choice C) are not used to confirm the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a standard diagnostic procedure for Hirschsprung disease and does not provide the necessary information to confirm the absence of ganglion cells in the affected bowel segment.

Correct Answer: D

Rationale: Teaching seizure first aid to family members is crucial in ensuring the child's safety during a seizure. This education empowers family members to respond effectively, protect the child from injury, and provide appropriate care. Option A is incorrect because antiepileptic medication should be administered as prescribed, not only when a seizure occurs. Option B, while important for overall health, is not specific to managing seizures. Option C is incorrect as there is no evidence that restricting activities prevents seizures, and it may negatively impact the child's quality of life without offering additional safety benefits.

Correct Answer: B

Rationale: Systolic blood pressure is the least reliable parameter when assessing the perfusion status of a 2-year-old child with possible shock. In pediatric patients, especially young children, blood pressure may not decrease until significant shock has already occurred, making it a late indicator of inadequate perfusion. Depending solely on systolic blood pressure to evaluate perfusion status in this age group can lead to a delay in appropriate interventions. Distal capillary refill time, skin color, and temperature changes, and the presence of peripheral pulses are more sensitive and early indicators of perfusion status in pediatric patients. Monitoring distal capillary refill provides information on peripheral perfusion, while changes in skin color and temperature can signal circulatory compromise. Evaluating the presence or absence of peripheral pulses offers insights into vascular perfusion. These parameters offer more reliable and prompt feedback on a child's perfusion status compared to systolic blood pressure.
