Final answer:
The appropriate medications to treat Katie's GERD would be proton pump inhibitors (PPIs) and antacids.
Step-by-step explanation:
GERD, or gastroesophageal reflux disease, is a condition characterized by the backward flow of stomach acid into the esophagus. Treatment for GERD typically involves medications that reduce the production of stomach acid or neutralize existing acid in the stomach to relieve symptoms and prevent further damage. In Katie's case, the appropriate medications to treat her GERD would be proton pump inhibitors (PPIs) and antacids. PPIs, such as omeprazole (Prilosec), work by decreasing the amount of acid made in the stomach. They are often prescribed for more severe cases of GERD. Antacids, like calcium carbonate (found in Tums), are substances that neutralize excess stomach acid. They provide quick relief from heartburn symptoms but are not as effective at reducing acid production as PPIs.
