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: High fever is a key clinical manifestation of bacterial meningitis due to the inflammatory response in the meninges. Photophobia, choice A, is also commonly observed due to meningeal irritation, but it is not as specific as high fever. Rash, choice C, is more indicative of conditions like meningococcal meningitis rather than bacterial meningitis. Nasal congestion, choice D, is not typically associated with bacterial meningitis. Therefore, the correct answer is B.

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: B

Rationale: The short urethra in young girls predisposes them to urinary tract infections. In young girls, the proximity of the urethra to the anus and the shorter urethra compared to boys make it easier for bacteria to travel up the urinary tract, increasing the risk of infection. Increased fluid intake and frequent emptying of the bladder are actually helpful in preventing urinary tract infections by flushing out bacteria. Prostatic secretions in males are not a factor in predisposing the urinary tract to infection in children.
