This child has signs and symptoms consistent with hemolytic uremic syndrome (HUS). Key points: - Bloody diarrhea 7 days after consuming undercooked meat suggests infection with Shiga toxin-producing E. coli (STEC), the most common cause of typical HUS. - Lab findings show microangiopathic hemolytic anemia (schistocytes on smear), thrombocytopenia, and renal insufficiency (elevated BUN/creatinine), confirming the diagnosis of HUS. - Supportive care is the mainstay of treatment. Given the likely STEC etiology, antibiotics are not indicated but close monitoring and fluid/electrolyte management are needed given the renal involvement
