GI MEDS AND PLAN OF CARE PLAN FOR THE DAY: Quick Notes Review Case Study NCLEX Questions

GASTRIC ACID System Esophagus Stomach Liver/gallbladder Pancreas Small/large intestine Gastric acid production Parietal cells- H+ production Receptors- histamine2 Function Stomach pH 1-4 Digestion Defense against infection

WHAT DO WE DO WITH THE OVERPRODUCTION OF THIS ACID???? ****Give antacids= to neutralize! Milk of Magnesia (magnesium hydroxide) TUMS (calcium carbonate) Heartburn, gastritis, peptic ulcer disease (PUD) ****Suppress gastric acid! H2 receptor blockers- bind to H2 receptor Pepcid (famotidine) Decrease HCl acid production Decrease heartburn GERD, erosive esophagitis, PUD, H. pylori, gastritis, prevent stress ulcers

Gastric barrier- adheres to gastric mucosa/ binds to ulcer Carafate (sucralfate) Decrease heartburn v=_fa60VhclNo&feature=related v=_fa60VhclNo&feature=related WHAT DO WE DO WITH THE OVERPRODUCTION OF THIS ACID???? ****Suppress gastric acid! Proton pump inhibitors (PPI)- blocks proton pump, stops HCl production Prevacid (lansoprazole) Prilosec (omeprazole) Protonix (pantoprazole) Decrease HCl production, decrease heartburn Caution with hepatic disease!!!!
