Correct Answer: B

Rationale: "Currant jelly" stools, consisting of mucus and blood, are characteristic of intussusception in children. It occurs due to the telescoping of a segment of the intestine into an adjacent segment, leading to obstruction and subsequent mucosal ischemia, causing the passage of bloody mucus in the stool. Bilious vomiting can be seen in other conditions like bowel obstruction, abdominal distention can be present but is not as specific, and constipation is less likely in the presentation of intussusception.

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: D

Rationale: Sweating is indeed one of the earliest signs of hypoglycemia in children with Type 1 diabetes. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, which can lead to sweating. While irritability, rapid heartbeat, and confusion can also be seen in hypoglycemia, sweating is particularly common as a quick indicator of low blood sugar levels in children with Type 1 diabetes.

Correct Answer: B

Rationale: The correct answer is B, the Hepatitis B vaccine. This vaccine is recommended for all newborns to prevent Hepatitis B infection, which can lead to chronic liver disease and liver cancer. The Hepatitis B vaccine is a crucial part of the routine immunization schedule for infants. Choices A, C, and D are incorrect because the recommended vaccine for newborns is specifically Hepatitis B, not Hepatitis A, Hepatitis C, or a combination of Hepatitis A, B, and C vaccines.

Correct Answer: A

Rationale: Restlessness is an early sign of shock due to decreased perfusion and oxygenation to the brain. This symptom requires immediate attention to prevent the progression to more severe stages of shock. Rapid capillary refill (Choice B) is not typically an early sign of shock but rather a sign of adequate perfusion. Increased temperature (Choice C) may occur in later stages of shock due to the body's response to stress. Increased blood pressure (Choice D) is not an early sign of shock; in fact, blood pressure tends to decrease in shock as a compensatory mechanism.
