Correct Answer: C

Rationale: The correct priority in dealing with a child suspected of having Wilms tumor is ensuring the abdomen is protected from palpation. Palpating the abdomen could lead to tumor dissemination, which is crucial to prevent the spread of cancerous cells. Intervening to minimize bleeding, monitoring temperature for infection, and teaching parents how to manage parenteral nutrition are not the immediate priorities in suspected cases of Wilms tumor.

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.

Correct Answer: B

Rationale: The correct answer is B. Meckel diverticulum often presents with intestinal bleeding, which can vary in severity. It is a congenital condition, meaning it is present from birth, not acquired during childhood (choice A). Meckel diverticulum is slightly more common in males than in females, so it does not occur more frequently in females (choice C). While some cases of Meckel diverticulum may require surgical intervention, medical interventions can also be sufficient to treat the problem, so it is not always necessary to resort to surgery (choice D).

Correct Answer: C

Rationale: When supporting a family whose infant has been diagnosed with biliary atresia, it is important to consider that liver transplantation may be needed eventually. Biliary atresia is a serious condition where bile flow from the liver to the gallbladder is blocked or absent. While surgical interventions like the Kasai procedure can temporarily improve bile flow and delay the need for transplantation, the long-term survival often depends on liver transplantation as the child grows older. Choices A, B, and D are incorrect because the prognosis for full recovery is not excellent as biliary atresia is a chronic condition that often requires ongoing medical management, death usually does not occur by 6 months of age but the condition does require intervention, and not all children with surgical correction can live normal lives without the need for further interventions like transplantation.

Correct Answer: B

Rationale: The correct answer is B: Wheezing. Wheezing is a key distinguishing feature of bronchiolitis in infants, typically caused by respiratory syncytial virus (RSV) infection. Bronchiolitis is characterized by inflammation and mucus buildup in the small airways of the lungs, leading to wheezing sounds during breathing. Choices A, C, and D are incorrect because dry cough, stridor, and productive cough are not typical features of bronchiolitis in infants.
