A male patient presents with complaints of chronic stomach pain and is diagnosed with a Helicobacter pylori infection. The physician decides to initiate triple therapy. Which combination of medications is most appropriate for this treatment?
Amoxicillin, Clarithromycin, and Omeprazole
Ciprofloxacin, Metronidazole, and Ranitidine
Erythromycin, Amoxicillin, and Famotidine
Metronidazole, Tetracycline, and Bismuth subsalicylate
The Correct Answer is A
A. Amoxicillin, Clarithromycin, and Omeprazole: This is the most common combination used in triple therapy for H. pylori eradication. It includes two antibiotics (Amoxicillin and Clarithromycin) to eliminate the bacteria, and a proton pump inhibitor (Omeprazole) to reduce stomach acid and promote healing.
B. Ciprofloxacin, Metronidazole, and Ranitidine: Ciprofloxacin and Metronidazole are not typically part of the standard regimen for H. pylori infection. Ranitidine is an H2-receptor antagonist, not commonly used in current treatment protocols for H. pylori.
C. Erythromycin, Amoxicillin, and Famotidine: Erythromycin is not part of the standard H. pylori treatment regimen, and Famotidine is an H2-receptor antagonist, which is less effective than proton pump inhibitors for H. pylori.
D. Metronidazole, Tetracycline, and Bismuth subsalicylate: This combination is used in quadruple therapy for H. pylori infections, but it is not the most common initial treatment.

Correct Answer is B
Explanation
A. "Vomiting blood or material that looks like coffee grounds is a serious sign that I need to go to the emergency room." This is a correct understanding. Vomiting blood or coffee-ground material is a sign of gastrointestinal bleeding and requires immediate medical attention.
B. "If I experience severe abdominal pain, I should take an over-the-counter antacid and rest."
Taking an over-the-counter antacid without contacting a healthcare provider for severe pain could mask serious complications, such as recurrent bleeding or perforation, that need immediate medical attention. This statement indicates a need for further teaching.
C. "I should avoid taking NSAIDs like ibuprofen as they can increase my risk of bleeding." This is a correct understanding, as NSAIDs can cause or worsen gastric ulcers and increase the risk of bleeding.
D. "I should immediately report any black, tarry stools to my healthcare provider."This is a correct understanding. Black, tarry stools (melena) indicate upper gastrointestinal bleeding.
Correct Answer is B
Explanation
A. Eat a diet high in calcium oxalate-rich foods: This is incorrect. A diet high in oxalate can promote stone formation, so it should be avoided.
B. Drink plenty of fluids during the day. Adequate hydration is the most important strategy to prevent the formation of renal calculi, especially in hot climates where fluid loss through sweat increases the risk.
C. Eat a diet high in purine-rich foods: This is incorrect. Purine-rich foods can increase uric acid levels and contribute to uric acid stone formation, especially in clients with gout.
D. Continue to take your prescribed gout medication: While this is important for managing gout, it does not directly prevent renal calculi, so it is not the most relevant intervention.
