Final answer:
The nurse should anticipate teaching the patient about diagnostic procedures like the barium swallow and endoscopy, as well as treatment options like proton pump inhibitors for frequent heartburn.
Step-by-step explanation:
In response to a patient experiencing frequent heartburn, a nurse should anticipate teaching about various diagnostic options and treatments. Potential diagnostics include a barium swallow, which is a medical imaging test using barium sulfate to help diagnose acid reflux disease and other conditions. In addition, an endoscopy procedure might be recommended, which involves using an endoscope—a tube with a tiny camera—to examine the patient's upper gastrointestinal tract for issues such as peptic ulcers. Lastly, for treatment, discussing the use of proton pump inhibitors may be pertinent, as they are medications that reduce stomach acid production and can be effective in preventing heartburn.
