What is the primary treatment for Kawasaki disease?

Correct Answer: B

Rationale: The correct answer is B, Intravenous immunoglobulin (IVIG). IVIG is the primary treatment for Kawasaki disease, an acute vasculitis that mainly affects children under 5 years old. Early administration of IVIG is crucial as it helps reduce the risk of coronary artery aneurysms, which is the most serious complication of Kawasaki disease. Corticosteroids (Choice A) are not the primary treatment for Kawasaki disease and are not recommended due to potential adverse effects. Antibiotics (Choice C) are not indicated for the treatment of Kawasaki disease as it is not caused by a bacterial infection. Antivirals (Choice D) are also not part of the standard treatment for Kawasaki disease, as it is not caused by a viral infection.

Correct Answer: C

Rationale: The correct answer is C: Side-lying. The side-lying position is recommended after a tonsillectomy to facilitate drainage of secretions and reduce the risk of aspiration. This position helps prevent blood from pooling in the back of the throat, decreasing the chance of bleeding postoperatively. Supine (lying face up), while commonly used in other situations, may not be ideal immediately after a tonsillectomy due to the risk of airway obstruction from blood clots. Prone (lying face down) is not recommended as it can hinder breathing and increase the risk of complications. Fowler's position (semi-sitting) is also not typically used after a tonsillectomy because it may cause discomfort and hinder proper drainage.

Correct Answer: A

Rationale: The correct answer is A, Hepatitis B. The Hepatitis B vaccine is usually given at birth to protect against hepatitis B, a virus that can lead to chronic liver disease and liver cancer. This vaccination is crucial for newborns, especially those born to mothers who are carriers of hepatitis B. Choices B, C, and D are incorrect because DTaP (B), MMR (C), and Varicella (D) vaccines are not typically administered at birth. DTaP is given in a series starting at 2 months, MMR is usually given around 12-15 months, and Varicella is given between 12-15 months of age.

Correct Answer: B

Rationale: Rotavirus is the leading cause of acute gastroenteritis in children under 5 years. It leads to severe diarrhea and dehydration. Vaccination against rotavirus has significantly reduced the incidence of this disease, but it remains a major cause of morbidity in young children globally. Salmonella and Shigella can cause gastroenteritis, but they are less common in children under 5 years. Norovirus is also a common cause of gastroenteritis, but Rotavirus is the most prevalent in this age group.

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.
