Which condition is most commonly associated with a 'sunset sign' in infants?

Correct Answer: A

Rationale: The 'sunset sign,' characterized by downward-driven eyes, is most commonly associated with hydrocephalus. This condition causes increased intracranial pressure, leading to the eyes appearing to be forced downward. Meningitis (choice B) typically presents with symptoms such as fever, headache, and a stiff neck, but not the 'sunset sign.' Cerebral palsy (choice C) is a group of disorders affecting movement and muscle coordination, not directly related to the 'sunset sign.' Encephalitis (choice D) is inflammation of the brain, which can cause symptoms like fever, headache, and confusion, but not the specific downward eye gaze seen in the 'sunset sign.'

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: C

Rationale: The correct answer is C: Urine output. Assessing urine output is a recommended method to determine hydration status in infants. Adequate urine output indicates good hydration, while decreased urine output may suggest dehydration. Capillary refill time (Choice A) is more indicative of circulatory status rather than hydration. Skin turgor (Choice B) is a useful assessment in adults but can be less reliable in infants. Checking mucous membranes (Choice D) can provide some information on hydration, but it is not as reliable as assessing urine output in infants.

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.
