Which of the following is a key feature of autism spectrum disorder?
- A. Delayed speech development
- B. Hyperactivity
- C. Lack of interest in toys
- D. Aggressive behavior
Correct Answer: A
Rationale: Delayed speech development is a significant feature of autism spectrum disorder. Many children with autism exhibit delays in speech and language development, which can be one of the early signs of the condition. Hyperactivity, lack of interest in toys, and aggressive behavior are not key defining features of autism spectrum disorder. While some individuals with autism may exhibit these behaviors, they are not universally characteristic of the disorder.

Which of the following is a characteristic finding in Kawasaki disease?
- A. Strawberry tongue
- B. Polyarthritis
- C. Hematuria
- D. Rashes
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.
What intervention is contraindicated in a suspected case of appendicitis?
- A. Enemas
- B. Palpating the abdomen
- C. Administration of antibiotics
- D. Administration of antipyretics for fever
Correct Answer: A
Rationale: Enemas are contraindicated in cases of suspected appendicitis because they can increase the risk of perforation. The pressure from the enema can exacerbate inflammation and potentially lead to the rupture of the appendix. Palpating the abdomen gently is essential for diagnosing appendicitis, as it helps identify the characteristic signs like rebound tenderness. Antibiotics are commonly used to treat the infection associated with appendicitis, and antipyretics are administered to manage fever, which is a common symptom of the condition. Therefore, enemas are the intervention to avoid in suspected appendicitis cases.
What is the most common cause of acute gastroenteritis in children under 5 years?
- A. Salmonella
- B. Rotavirus
- C. Norovirus
- D. Shigella
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.
Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?
- A. Tetralogy of Fallot
- B. Coarctation of the aorta
- C. Transposition of the great arteries
- D. Ventricular septal defect
Correct Answer: A
Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.
A child has been diagnosed with a Wilms tumor. What should preoperative nursing care include?
- A. Careful bathing and handling
- B. Monitoring of behavioral status
- C. Maintenance of strict isolation
- D. Administration of packed red blood cells
Correct Answer: A
Rationale: The correct answer is A: Careful bathing and handling. Preoperative care for a child with a Wilms tumor should focus on preventing any trauma to the abdomen, which could lead to tumor rupture. Monitoring behavioral status and maintaining strict isolation are not as critical in this situation. Behavioral status is important but not a priority in preoperative care for a Wilms tumor. Strict isolation is not necessary unless there are specific infectious concerns, which is not typically the case for a Wilms tumor. Administration of packed red blood cells is not a standard preoperative intervention for Wilms tumor.
