Final answer:
When considering gastroesophageal reflux as a differential diagnosis for recurrent heartburn, symptoms such as eructation, cough, and dysphonia can be anticipated. However, hematemesis is not typically associated with GERD.
Step-by-step explanation:
Gastroesophageal reflux disease (GERD) is a condition characterized by the backward flow of stomach acid into the esophagus, causing symptoms such as heartburn. When evaluating a patient with recurrent heartburn, a nurse practitioner would anticipate symptoms such as eructation (burping), cough, and dysphonia (hoarseness). However, hematemesis (vomiting blood) would not typically be anticipated as a symptom of GERD. It is important to note that the presence of hematemesis may indicate a more serious condition and should be evaluated by a healthcare professional.
