Answer to Question 1
C
The antibiotics administered most often are amoxicillin, clarithromycin, bismuth, metronidazole, and tetracycline. None is effective alone, hence the combination of clarithromycin and amoxicil-lin. The antibacterial activity of amoxicillin is highest at a neutral pH and can be enhanced by reducing gastric acidity with an antisecretory agent, such as esomeprazole. This combination is an appropriate treatment plan.
Metronidazole is very effective against sensitive strains; however, more than 40 of strains are now resistant. One antibiotic alone is not effective in treating H. pylori. Cimetidine promotes healing of ulcers, therefore it would be an important drug to include in the treatment plan.
Although two antibiotics are included, only tetracycline is effective against H. pylori. Cimetidine promotes healing of ulcers, therefore it would be an important drug to include in the treatment plan.
Although cimetidine and bismuth are appropriate in the treatment plan, amphotericin B is an an-tifungal agent and would have no effect on H. pylori.
