A nurse is caring for a child who has Hirschsprung’s disease. Which of the following findings should the nurse expect? (Select all that apply)

Choice A reason: Hirschsprung’s disease, caused by absent ganglion cells in the colon, leads to functional obstruction, resulting in ribbon-like, foul-smelling stools due to fecal retention and bacterial overgrowth. This is a hallmark finding, as narrowed stools reflect the aganglionic segment’s inability to propel feces normally, causing constipation and malodorous output.

Choice B reason: A rigid abdomen is not typical in Hirschsprung’s disease, which causes distension from fecal retention, not rigidity. Rigidity suggests peritonitis or other acute conditions. Ribbon-like stools are more characteristic, reflecting the chronic obstruction, making this an incorrect expected finding in this congenital disorder.

Choice C reason: Projectile vomiting is associated with pyloric stenosis, not Hirschsprung’s disease, which affects the colon, causing constipation and stool abnormalities. Vomiting may occur in severe obstruction but is not primary. Ribbon-like stools are more specific, making projectile vomiting an incorrect expected finding in this condition.

Choice D reason: Chronic hunger is not a feature of Hirschsprung’s disease, which causes constipation and abdominal distension, potentially reducing appetite due to discomfort. Nutritional issues arise from obstruction, not hunger. Ribbon-like stools reflect the disease’s pathophysiology, making chronic hunger an incorrect expected manifestation in affected children.

Step 1 is to convert pounds to kilograms: (22 ÷ 2.2) = 10 Result = 10 kg

Step 2 is to calculate the total dose in mg: 10 × 10 = 100 Result = 100 mg

Step 3 is to find out how many mL contains 100 mg when 160 mg is in 5 mL: (100 ÷ 160) × 5 = Step 3a is (100 ÷ 160) = 0.625 Step 3b is 0.625 × 5 = 3.125 Result = 3.125 mL

Step 4 is to round to the nearest tenth: 3.125 rounds to 3.1

Final result = 3.1 mL
