The Blood in Your Patient's Stool Suggests an Ulcer

The blood in your patient's stool suggests an ulcer. The endoscopy confirms this. You discuss with the patient how H. pylori can cause ulcers. After H. pylori enters your body, it can cause damage to cells in the lining of the stomach, some of which usually produce a protective mucus layer. Once the bacteria have done enough damage, the mucus layer thins and stomach acid can get through the lining, leading to ulcers. You prescribe an antacid medication

A) to kill the H. pylori which can only live in acidic conditions.
B) to reduce the acidity of the stomach, thereby allowing the lining to heal.
C) to prevent the H. pylori from making CO2 which is causing the patient's burping.
D) to stimulate the patient's stomach E. coli population so it out-competes the pathogen.
E) All of the answer choices are correct.
