CHAPTER 7 Gastrointestinal System^289
- Nausea and vomiting, especially following fatty foods
 - Loss of appetite
 - Fever
 - Increased air in intestinal tract (eructation, flatulence)
 - Pruritis (itching) of skin due to build-up of bile salts
 - Clay-colored stools due to lack of urobilinogen in gut (normally converted
from bilirubin which was blocked with bile flow) - Jaundice—yellowish skin and mucous membrane discoloration
 - Icterus—yellowish discoloration of sclera (white of eye)
 - Dark, foamy urine as kidneys attempt to clear out bilirubin
 
INTERPRETING TEST RESULTS
- Ultrasound of gallbladder shows cholelithiasis, inflammation.
 - HIDA scan (hepatic iminodiacetic acid) may be more sensitive than ultra-
sound in showing obstructed duct. - CT scan shows inflammation or cholelithiasis.
 - MRCP (magnetic resonance cholangiopancreatography).
 - ERCP (endoscopic retrograde cholangiopancreatography).
 - Bilirubin direct (conjugated) and indirect (unconjugated) will be elevated if
there is obstruction. - White blood cell (WBC) count elevation with inflammation.
 - Alkaline phosphatase, aspartate aminotransferase (AST), and lactate dehy-
drogenase (LDH) will be elevated with abnormal liver function. 
TREATMENT
- Low-fat diet.
 - Intravenous fluid replacement for vomiting.
 - Administer antiemetics for control of nausea and vomiting:
- prochlorperazine
 - trimethobenzamide
 
 - Replace fat-soluble vitamins (A, D, E, K) as needed.
 - Administer analgesics for adequate pain control:
- meperidine
