In evaluating Billy, a child with bloody diarrhea, which of the following would not be appropriate first action?

• A. Check growth chart
• B. Stool culture
• C. Upper GI
• D. Hemoccult test stools

Answer: (C)

When evaluating a child with bloody diarrhea, begin with noninvasive steps that reveal current status and potential infectious or nutritional issues. Checking growth over time helps identify ongoing malnutrition or growth faltering that can accompany chronic GI problems. A stool culture is important to detect bacterial pathogens that can cause bloody diarrhea and guide appropriate treatment and isolation precautions. A hemoccult test on stools helps assess the extent of intestinal bleeding and can support the urgency of further workup. An upper GI study, by contrast, focuses on the esophagus, stomach, and duodenum and is used to evaluate upper GI disease rather than lower GI bleeding; it is invasive, involves radiation and contrast, and is unlikely to yield useful information about a lower GI source in an acute case. Therefore it is not the first action in the initial assessment.
