A patient diagnosed with PUD is being discharged with a prescription for a proton pump inhibitor (PPI) and an antibiotic. What key instruction should the nurse provide regarding the antibiotic therapy?

Correct Answer: B

Rationale: Completing the full antibiotic course ensures H. pylori eradication, preventing PUD recurrence.

Correct Answer: B

Rationale: Upper GI endoscopy directly visualizes ulcers and abnormalities in the stomach and duodenum.

Correct Answer: C

Rationale: Chocolate stimulates acid production, exacerbating PUD symptoms.

Correct Answer: C

Rationale: Gastritis is characterized by inflammation of the stomach lining, commonly due to factors like H. pylori infection, excessive alcohol consumption, or chronic NSAID use, which disrupt the mucosal barrier and lead to inflammation. Overproduction of bile acids is more related to bile reflux, not a primary cause of gastritis. Erosion due to gastric acid is more indicative of peptic ulcer disease progression rather than gastritis alone. Ulcer formation in the duodenum pertains to duodenal ulcers, not gastritis.

Correct Answer: D

Rationale: Any link between cirrhosis and Crohn's disease is dubious, though there may be an increase because of transfusion-related viral hepatitis or end-stage primary screening. It is important to look for other actiologies such as alcohol if cirrhosis does occur in these patients.
