- Biliary system: liver is large at birth (5% weight), Enzymes reach adult levels at 2 years

greater amounts of water/urine in proportion to weight.

Health History: GI ✅- previous illness/surgery
- past family history

- how have you managed these symptoms
- growth patterns
-allergies, bowel disease, IBS family history

with liver dysfunction and high bilirubin levels), assess abdomen for signs of distended
veins
- Normal "pot belly" in toddlers.
- Altered mental status with increased ammonia levels (liver failure, hepatic
encephalopathy-abnormal brain function), altered electrolytes, dehydration,
anaphylactic reaction to foods/meds. Early sign irritability and restlessness.

Auscultation GI ✅What causes hyperactive bowel sounds: diarrhea, gastroenteritis
Hypoactive: obstructive process: emergent
How long do you have to listen to state absent? 5 minutes

Percussion GI ✅- You will hear dullness over bladder that is full which may initially
seem like an ominous finding - but it is a full bladder! You will note tympany everywhere
else. Dullness is heard in the RUQ over the liver.

enlargement or cholecystitis
