A comprehensive i-Human case study for 2025/2026 on an 18-month-old child presenting with acute vomiting, watery diarrhea, and moderate dehydration. This case explores the systematic evaluation and management of acute viral gastroenteritis in a toddler, including history taking, physical examination, hydration assessment using validated scales (CDS, WHO), diagnostic reasoning, and evidence-based oral rehydration therapy (ORT). Covers key topics such as fluid deficit calculation, electrolyte monitoring, dietary advancement (BRAT diet), red flag recognition (intussusception, bacterial gastroenteritis), and family education on home management and when to seek care. Ideal for advanced practice nursing, medical students, and pediatric primary care clinicians preparing for i-Human simulations, NRNP coursework, and pediatric clinical rotations.
