Rationale: Hemolytic uremic syndrome is the most common cause of acute kidney injury in children. While dehydration can lead to prerenal acute kidney injury, it is not the most common cause in children. Glomerulonephritis is a common cause of chronic kidney disease but not typically the most common cause of acute kidney injury in children. Sepsis can lead to acute kidney injury, but in children, hemolytic uremic syndrome is more prevalent.

Correct Answer: B

Rationale: Teaching infection control measures is crucial as Hepatitis A is highly contagious, especially in household settings. Proper hand hygiene and avoiding sharing personal items can prevent the spread of the virus within the family. Option A is incorrect because bed rest is not typically required for hepatitis A. Option C is incorrect as the child can return to school once feeling well and no longer contagious, not necessarily after a specific duration. Option D is incorrect because hepatitis A can be transmitted through contaminated food, water, or close personal contact.

Correct Answer: C

Rationale: A high-calorie diet is recommended for children with cystic fibrosis due to their increased energy needs and malabsorption issues. Cystic fibrosis affects the pancreas, leading to poor digestion and absorption of nutrients, particularly fats, which requires dietary adjustments to maintain adequate nutrition. High carbohydrate (Choice A) is not the primary focus; the emphasis is on overall calorie intake. Low protein (Choice B) is not recommended as protein intake is essential for growth and development. Low fat (Choice D) is not the best option as fat-soluble vitamin absorption is already compromised in cystic fibrosis, hence fat restriction is not a priority.

Correct Answer: B

Rationale: The correct answer is B: Hypertrophic pyloric stenosis. The "string sign" is associated with hypertrophic pyloric stenosis, a condition where the pyloric canal is narrowed, leading to gastric outlet obstruction. Intussusception (choice A) typically presents with colicky abdominal pain and currant jelly stools. Hirschsprung disease (choice C) is characterized by the absence of ganglion cells in the distal colon. Meckel diverticulum (choice D) is a congenital outpouching of the small intestine that can present with painless rectal bleeding.

Correct Answer: A

Rationale: Handwashing is indeed the most effective way to prevent the spread of hand, foot, and mouth disease in children. Proper hand hygiene helps in removing and killing germs that can cause infections. While isolating sick children and disinfecting toys are important measures to prevent the spread of diseases, they are not as effective as handwashing. Encouraging vaccination, in this case, is not relevant since there is no specific vaccine available for hand, foot, and mouth disease.
