, Review of Systems (ROS)
Constitutional: Decreased appetite, irritability
GI: Vomiting, diarrhea, decreased intake
GU: Decreased urine output
Skin: No rash
Respiratory: No cough or shortness of breath
Neurologic: No seizures or focal deficits
Physical Examination
Vital Signs:
• Temp: Mildly elevated
• HR: Mild tachycardia
• RR: Normal
• BP: Stable
• SpO₂: Normal on room air
General: Ill-appearing toddler, mildly lethargic but arousable
HEENT: Dry mucous membranes, sunken eyes
Cardiovascular: Tachycardic, regular rhythm
Respiratory: Clear to auscultation bilaterally
Abdomen: Soft, non-distended, mild diffuse tenderness, hyperactive bowel sounds
Skin: Decreased skin turgor, warm, no rash
Neuro: Alert, appropriate for age
Assessment
Primary Diagnosis:
Acute viral gastroenteritis with mild–moderate dehydration
Differential Diagnoses
1. Viral gastroenteritis (most likely) – common in toddlers, daycare exposure,
vomiting/diarrhea
2. Bacterial gastroenteritis – less likely due to absence of blood or high fever
3. Food intolerance or food poisoning – less likely, no known ingestion
4. Urinary tract infection – consider in young children but GI symptoms predominate
