Final answer:
Chronic gastritis caused by Helicobacter pylori is implicated in the development of peptic ulcers and gastric cancer.
Step-by-step explanation:
The nurse is conducting a community education class on gastritis. When discussing the implications of chronic gastritis caused by Helicobacter pylori, it is important to mention that this bacterium is a major cause of peptic ulcers and is also associated with an increased risk of gastric cancer. H. pylori can persist in the highly acidic environment of the stomach by producing urease, which modifies the local acidity. Over time, the chronic inflammation caused by this bacterium can lead to peptic ulcers, which are sores that develop in the lining of the stomach or duodenum. Moreover, studies have shown a link between H. pylori infection and stomach cancer. Therefore, the correct answer to the question, which disease or condition chronic gastritis caused by H. pylori is implicated in, is both a. Peptic ulcers and b. Gastric cancer.
