Correct Answer: A

Rationale: The correct answer is to maintain a structured routine. Children with autism spectrum disorder benefit greatly from structured routines as they provide a sense of stability and predictability, which can help reduce anxiety and improve behavior. Encouraging social interaction (Choice B) is important but may need to be approached in a structured manner to prevent overwhelming the child. Positive reinforcement (Choice C) is also beneficial for behavior management but may not address the overall need for routine and predictability that is crucial for children with autism. Using a communication board (Choice D) may be helpful for facilitating communication, but establishing and maintaining a structured routine is fundamental for supporting the child's development and well-being in managing their autism spectrum disorder.

Correct Answer: D

Rationale: The most common treatment for Hirschsprung disease is the surgical removal of the affected section of the bowel. This procedure entails excising the part of the colon that lacks nerve cells crucial for normal bowel function. Daily enemas (Choice A) can offer temporary relief for constipation but do not address the root cause of the condition, which is the absence of nerve cells. A low-fiber diet (Choice B) is not a primary therapy for Hirschsprung disease and may not effectively manage the disorder. A permanent colostomy (Choice C) is typically considered in severe cases where other interventions have failed and is not the standard management approach for Hirschsprung disease.

Correct Answer: A

Rationale: The correct answer is A. Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It results in the production of thick, sticky mucus that can clog the lungs and obstruct the pancreas. This explanation is crucial for parents to understand the impact of the condition on their child's health. Choice B is incorrect because cystic fibrosis is not an autoimmune disorder. Choice C is partially correct in that cystic fibrosis is a genetic disorder, but it requires a comprehensive management approach beyond just medication. Choice D is incorrect as cystic fibrosis is not caused by prenatal exposure to toxins but rather by inheriting specific genetic mutations.

Correct Answer: A

Rationale: Right lower quadrant pain is a classic symptom of appendicitis. The appendix is typically located in the right lower quadrant of the abdomen, so pain in this area is commonly associated with appendicitis. Choices B, C, and D are incorrect because left lower quadrant pain, rebound tenderness, and epigastric pain are not typical manifestations of appendicitis. Left lower quadrant pain is not associated with appendicitis since the appendix is situated in the right lower quadrant. Rebound tenderness is more commonly linked with peritonitis rather than appendicitis. Epigastric pain is not a typical presentation of appendicitis as the pain is usually localized to the right lower quadrant.

Correct Answer: A

Rationale: Infection is the leading cause of shock in infants and children due to their heightened vulnerability to sepsis. Infants and children possess developing immune systems, rendering them more susceptible to infections that can progress to septic shock. While cardiac failure is a severe condition, it is not as commonly the primary cause of shock in this age group. Accidental poisoning, though a potential shock inducer, is less prevalent in infants and children compared to infections. Severe allergic reactions, though significant, are not as frequent as infections in precipitating shock in infants and children.
