History of Present Illness
Mia Johnson, an 18-month-old female, is brought to the pediatric clinic
by her mother with a chief complaint of vomiting and diarrhea for 2
days. The mother reports that Mia has had 5–6 episodes of non-bloody,
non-bilious vomiting per day, consisting of partially digested food and
formula. The diarrhea is described as watery, non-bloody, with 6–8
episodes daily, occurring shortly after feeding or at random times. The
stools are loose, yellowish, and foul-smelling, with no mucus or blood
noted. The mother estimates a decrease in diaper output (2–3 wet
diapers/day compared to her usual 6–8), raising concern for
dehydration. Mia has been increasingly irritable, less active, and has
had a decreased appetite, refusing solid foods but taking small amounts
