T/F: H. pylori occurs in >90% or duodenal ulcers and >75% of gastric ulcers | True |
Sx's of PUD | gnawing epigastric pain that is well localized |

What does Sucralfate (Carafate) require in order to work and what should be avoided | an acidic environment needs to be present; avoid antacids and H@ blockers |
What are the actions of Bismuth subsalicylate (Pepto Bismal) | ~direct antibacterial action against H. pylori ~promotes prostaglandin production/stimulates gastric bicarb |
T/F: Misoprostol (Cytotec) should be taken with food | True |
What are the actions of Misoprostol (Cytotec)... | ~used as prophylaxis against NSAID-induced ulcers ~stimulates mucous and bicarb production ~may stimulate uterine contractions and induce abortion |
Do antacids reduce the amount of gastric acidity? | NO |
What is the combo option therapy for H. pylori | 2 antibx + either a PPI or Bismuth |

Anti-HAV, IgM will peak at about... | the first week of clinical illness |
Anti-HAV, IgM will disappear in about... | 3-6 months |
T/F: Anti-HAV will be either active or recovered | True |
What surface antigen is the 1st evidence of HBV infection | Hepatitis B surface antigen (HBsAg) |
HBsAg remains (+) in ______________ carriers and ____________ Hep B patients | "asymptomatic" "chronic" |
