Correct Answer: A

Rationale: The Ortolani sign is a specific maneuver used during physical examination to detect hip instability or dislocation in infants. A positive Ortolani sign, where the hip is felt to slip back into the socket, is indicative of developmental dysplasia of the hip, a condition that can lead to long-term disability if not treated early. Romberg sign is used to assess sensory ataxia, Trendelenburg sign indicates weakness of the hip abductor muscles, and Gower's sign is seen in children with proximal muscle weakness climbing up their own body from a supine position due to conditions like muscular dystrophy.

Correct Answer: A

Rationale: The correct answer is A: Strawberry tongue. In Kawasaki disease, a 'strawberry tongue' is most indicative of the acute phase. This refers to the tongue appearing red and swollen with enlarged fungiform papillae, giving it a strawberry-like appearance. Joint pain (Choice B) is more commonly associated with other conditions like rheumatoid arthritis. Rash (Choice C) and peeling skin (Choice D) are also seen in Kawasaki disease but are not as specific to the acute phase as the presence of a strawberry tongue.

Correct Answer: C

Rationale: Preoperative care for a newborn with an anorectal malformation should include feedings with sterile water only. This approach is important to avoid complications before surgery. Gastrointestinal decompression is necessary to prevent abdominal distention and potential aspiration, making choice B incorrect. Frequent suctioning and placing the newborn in a supine position with the head elevated are not typically part of the preoperative care protocol for an anorectal malformation, thus choices A and D are incorrect.

Correct Answer: C

Rationale: The correct answer is C, 'Tripod.' In children with epiglottitis, the tripod position is recommended to help open the airway and ease breathing. This position involves the child sitting upright, leaning forward, and supporting themselves with their hands on their knees or another surface. This posture helps improve air entry into the lungs by maximizing the space for breathing. Choices A (Supine), B (Prone), and D (Semi-Fowler's) are incorrect. Placing a child with epiglottitis in the supine position may further obstruct the airway, while the prone position and semi-Fowler's position do not facilitate optimal air exchange in these cases.

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.
