Upper endoscopy
UGIB: Change in hemoglobin may not be evident up to ____ hours after bleeding event
72 hours
Most frequent PE finding of GU or DU

Melena is blood that has been in the GIT for at least _____ hours
14 hours
Gold standard of H. pylori testing
Histologic evaluation of endoscopic biopsy
Scleral icterus means bilirubin is >___ mg/dL
3
Best way to initially assess GIB
BP and HR
Most reliable marker of severity of liver disease and it’s hallmark symptom
Jaundice
Single most common risk factor for hep C infection:

Components of MELD
Bilriubin, INR, Creatinine
Medical management for portal hypertension
Nonselective beta blockers Splanchnic vasoconstrictors (Somatostatin, octreotide)
Chylous ascites indicates a TG level of
> 200 mg/dL
Remains the gold standard of determining cause of ascites
Laparotomy/laparoscopy with peritoneal biopsy
Patients with small amounts of ascites can be initially managed by:
Sodium restriction
Moderate amounts of ascites are managed with:
Diuretics (initially spironolactone)
Management for refractory ascites
Repeated large volume paracentesis and TIPS
In colonic adenoCA, obstruction here leads to hematochezia, narrowing of stool caliber, tenesmus
Rectosigmoid area
Colon CA: Best predictor of long-term prognosis

Urgent endoscopy is recommended in cirrhotics with UGIB within how many hours?
12 hours
Single best acute measure of hepatic synthetic function
Coagulation studies
Earliest radiologic change in ulcerative colitis
Fine granular changes
Earliest macroscopic finding in Crohn’s disease
Aphthous ulcers
Defining lesions of UC
Crypt abscesses and ulcers
Treatment of SBP
Cefotaxime/Ofloxacin/Ciprofloxacin + IV Albumin

7-14 days
Most important clinical finding in regard to severity of the acute pancreatitis episode
Persistent organ failure >48h
Initial imaging modality of choice for acute pancreatitis
Abdominal ultrasound

Pneumococcal vaccine should be administered 2 weeks [before/after] splenectomy
2 weeks before splenectomy
Usually the first indicator of portal hypertension
Hypersplenism
Perhaps the most reliable physical finding in the liver examination
Hepatic tenderness
Most common symptoms in Hep C

Most important factor in progression of Hep B into cirrhosis and HCCA
Level of HBV replication
Best therapy for hepatorenal syndrome
Liver transplant
Acetaminophen dose associated with fatal fulminant liver disease
25g and above
Most distinguishing serologic feature of chronic hep D
Anti-LKM3
Best prognostic factor in chronic Hep C
Liver histology
Mainstay of treatment of autoimmune hepatitis
