Therapeutic management of most children with Hirschsprung's disease is primarily

The correct answer is choice C. Activity intolerance related to generalized weakness.

Choice A rationale:

Risk for injury related to depressed sensorium. This choice is not the most appropriate nursing diagnosis for a child with moderate anemia. While anemia can lead to fatigue and weakness, the main concern is the child's ability to tolerate physical activities, not the risk of injury due to a depressed sensorium.

Choice B rationale:

Decreased cardiac output related to abnormal hemoglobin. This choice is not the most suitable nursing diagnosis for a child with moderate anemia. While abnormal hemoglobin levels can affect cardiac output, moderate anemia typically doesn't lead to such a significant decrease in cardiac output that it becomes the primary nursing diagnosis. Activity intolerance is a more relevant concern.

Choice C rationale:

Activity intolerance related to generalized weakness. This is the most appropriate nursing diagnosis for a child diagnosed with moderate anemia. Moderate anemia results in a decrease in oxygen-carrying capacity, leading to generalized weakness and reduced ability to perform physical activities without becoming fatigued. The child's hemoglobin levels are likely low enough to cause noticeable activity intolerance.

Choice D rationale:

Risk for Injury related to dehydration and abnormal hemoglobin. This choice is not the best nursing diagnosis for a child with moderate anemia. Dehydration may exacerbate the effects of anemia, but the primary issue here is the anemia itself causing weakness and activity intolerance, which are better addressed with the choice C diagnosis.

The correct answer is choice B: Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.

Choice A rationale:

Pulmonic stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy. This choice is incorrect because it includes "aortic hypertrophy" and "left ventricular hypertrophy," which are not components of the tetralogy of Fallot. Aortic hypertrophy is not a recognized structural defect in tetralogy of Fallot, and left ventricular hypertrophy is not a characteristic feature of this congenital heart condition.

Choice B rationale:

Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This is the correct choice. Tetralogy of Fallot is characterized by four specific structural defects: pulmonic stenosis (narrowing of the pulmonary valve), ventricular septal defect (hole between the right and left ventricles), overriding aorta (aorta positioned over the ventricular septal defect, receiving blood from both ventricles), and right ventricular hypertrophy (enlargement of the right ventricle due to increased workload).

Choice C rationale:

Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. This choice is incorrect because it includes "aortic stenosis," which is not part of the tetralogy of Fallot. In tetralogy of Fallot, the stenosis occurs at the pulmonary valve, not the aortic valve.

Choice D rationale:

Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy. This choice is incorrect. While "overriding aorta" is present in tetralogy of Fallot, "atrial septal defect" and "left ventricular hypertrophy" are not part of this condition. Atrial septal defects involve a hole between the two atria, not the ventricles, and left ventricular hypertrophy is not typically seen in tetralogy of Fallot.
