Which of the following is a key feature of autism spectrum disorder?

Correct Answer: A

Rationale: Delayed speech development is a significant feature of autism spectrum disorder. Many children with autism exhibit delays in speech and language development, which can be one of the early signs of the condition. Hyperactivity, lack of interest in toys, and aggressive behavior are not key defining features of autism spectrum disorder. While some individuals with autism may exhibit these behaviors, they are not universally characteristic of the disorder.

Correct Answer: B

Rationale: The most appropriate type of play for a hospitalized toddler is parallel play. This type of play allows toddlers to engage alongside each other but not directly with each other, which can be comforting and less overwhelming in a hospital setting. Cooperative play (choice A) involves working together towards a common goal, which may be challenging for a hospitalized toddler. Competitive play (choice C) involves a level of rivalry that may not be suitable during a hospital stay. Solitary play (choice D) involves playing alone, which may not provide the social interaction and distraction that parallel play can offer in a hospital environment.

Correct Answer: C

Rationale: Prolonged jaundice is a classic sign of congenital hypothyroidism in newborns. In congenital hypothyroidism, the thyroid gland does not produce enough thyroid hormones, leading to symptoms like jaundice, poor feeding, constipation, and lethargy. While jaundice itself is a common condition in newborns, the term 'prolonged jaundice' specifically points towards the underlying thyroid issue. Hypothermia and excessive crying are not typically associated with congenital hypothyroidism.

Correct Answer: C

Rationale: The correct answer is C: Pertussis. Pertussis, also known as whooping cough, is characterized by a "whooping" sound during coughing episodes. This distinctive sound is due to the rapid intake of air after a series of coughs. Choice A, Croup, typically presents with a barking cough and stridor. Choice B, Bronchitis, is characterized by a productive cough with mucus. Choice D, Asthma, usually presents with wheezing and shortness of breath.

Correct Answer: A

Rationale: The primary treatment goal for a child with juvenile idiopathic arthritis is pain management. Juvenile idiopathic arthritis is a chronic condition with no known cure, making pain management crucial to improve the quality of life for these children. While reducing joint deformity and physical therapy are important aspects of managing the condition, the primary focus is on alleviating pain and improving function.
