Why would a patient take a proton pump inhibitor? a. to prevent ulcers b. to treat a viral infection c. to reduce nasal congestion d. to relieve shortness of breath

Patients take proton pump inhibitors (PPIs) mainly to prevent and treat gastric ulcers and conditions caused by excess stomach acid, such as gastroesophageal reflux disease (GERD). By blocking the proton pumps in the stomach lining, these medications significantly decrease acid production, providing relief from symptoms like heartburn and allowing healing of the stomach and esophagus. While PPIs are essential for managing acid-related gastrointestinal issues, it's important to remember that they are not suitable for treating viral infections, reducing nasal congestion, or relieving shortness of breath. Misuse of these medications can lead to potential side effects, so they should always be taken under medical guidance.
