What is the earliest clinical manifestation of biliary atresia?

The correct answer is Choice D: Jaundice.

Choice A rationale:

Vomiting can occur in biliary atresia due to the blockage of bile flow, but it is not the earliest clinical manifestation. Jaundice tends to precede vomiting and is a more characteristic early sign of biliary atresia.

Choice B rationale:

Hepatomegaly (enlargement of the liver) is a common finding in biliary atresia, but it usually occurs after the onset of jaundice. Jaundice is an earlier and more specific manifestation of this condition.

Choice C rationale:

Absence of stooling is a sign that might occur in biliary atresia due to the obstructed bile flow, but it is not typically the earliest clinical manifestation. Jaundice is generally the first noticeable sign.

Choice D rationale:

Jaundice is the earliest clinical manifestation of biliary atresia. It is caused by the buildup of bilirubin in the blood due to impaired bile flow from the liver. The jaundice in biliary atresia is typically progressive and can be one of the key indicators for further evaluation and diagnosis.

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.
