What is the recommended method to assess hydration status in infants?

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: 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.

Correct Answer: A

Rationale: A 'strawberry tongue' is a characteristic finding in Kawasaki disease. The presence of a 'strawberry tongue' is a classic sign of Kawasaki disease, along with other features such as conjunctivitis and rash. Choice B, polyarthritis, is not typically seen in Kawasaki disease. Choice C, hematuria, is not a common finding in Kawasaki disease but may be seen in other conditions. Choice D, rashes, are present in Kawasaki disease but are not as specific or characteristic as the 'strawberry tongue'. Therefore, the correct answer is A.
