NP125 Med Surg Exam | Nurselytic

Correct Answer: B

Rationale: Endoscopy is a diagnostic procedure used for evaluating persistent or severe symptoms of heartburn, but it is not part of initial treatment. Patient education focuses on symptom relief and management strategies before invasive testing. Proton pump inhibitors reduce gastric acid secretion by irreversibly blocking H+/K+ ATPase in stomach parietal cells. They are first-line medications for heartburn and gastroesophageal reflux disease, effectively relieving symptoms and preventing complications. Radionuclide tests are specialized diagnostic procedures for conditions such as gastric emptying disorders. They are not standard educational topics for new heartburn complaints, as they do not provide immediate symptom relief. A barium swallow is used for imaging structural abnormalities of the esophagus or stomach but is not part of initial management for heartburn. It is a diagnostic tool rather than a first-line treatment or educational focus.
