Which description of stool is characteristic of intussusception?

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 A: Signs of stress.

Choice A rationale:

Children often express stress through physical complaints such as stomach pains, headaches, and fatigue. The 9-year-old's complaints of stomach pains, along with the description of aggressive and stubborn behavior, are indicative of stress. Stressors can include academic pressures, family issues, social challenges, or other emotional factors.

Choice B rationale:

Developmental delay refers to a situation where a child's developmental milestones are significantly delayed compared to their peers. This doesn't align with the presented symptoms of stomach pains, aggression, and stubbornness. These symptoms are more indicative of emotional or psychological distress.

Choice C rationale:

While a physical problem could potentially cause emotional stress, the scenario doesn't provide enough information to directly conclude that a physical problem is the primary trigger. Stomach pains could indeed result from emotional stress, and it's important to consider the child's overall well-being.

Choice D rationale:

Lack of adjustment to the school environment can lead to behavioral and emotional challenges, but it's not the most direct explanation for the symptoms described in the scenario. The combination of stomach pains and behavioral changes suggests a more immediate emotional trigger, which is often stress-related.
