What is an important priority in dealing with the child suspected of having Wilms tumor?

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: C

Rationale: The most common complication following surgical correction of esophageal atresia with tracheoesophageal fistula in infants is stricture formation. This complication occurs due to the healing process after surgery, leading to the narrowing of the esophagus. Gastroesophageal reflux (Choice A) can be a concern but is not the most common complication. Respiratory distress (Choice B) may happen but is not the primary complication. Aspiration pneumonia (Choice D) is a risk but is typically not as common as stricture formation in these cases.

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: B

Rationale: The correct answer is B: Encourage oral rehydration. Oral rehydration is the first-line treatment for moderate dehydration in children. It helps restore fluid balance and electrolyte levels. Administering IV fluids (Choice A) is usually reserved for severe cases of dehydration where oral rehydration is not feasible or ineffective. Monitoring vital signs (Choice C) is important but should not replace the immediate need for rehydration. Providing clear fluids (Choice D) may not contain the necessary electrolytes required for effective rehydration.

Correct Answer: B

Rationale: The primary concern with untreated vesicoureteral reflux (VUR) in pediatric patients is chronic renal failure. Untreated VUR can lead to this complication due to recurrent urinary tract infections and kidney damage. While recurrent UTIs (Choice A) are a common consequence of VUR, the ultimate worry is the development of chronic renal failure. Hypertension (Choice C) may occur as a result of renal damage but is not the primary concern. Bladder dysfunction (Choice D) is not the most significant consequence of untreated VUR in terms of long-term outcomes compared to chronic renal failure.
