A nurse is caring for a client with an
H. pylori infection.
Which of the following medications is an antibiotic used to treat
H. pylori infection?

Choice A rationale

Brand name medications are typically more expensive because they include costs for research, development, marketing, and patents. They are sold under a trademarked brand name by a specific company, which allows them to charge higher prices.

Choice B rationale

This is incorrect as brand name medications are not less effective than generic medications. Both are required to have the same active ingredients and efficacy by regulatory agencies.

Choice C rationale

While the active ingredients must be the same, the formulation (inactive ingredients) of brand and generic medications can differ, which may affect the drug's characteristics, such as absorption rate.

Choice D rationale

Brand name drugs are usually less prescribed than generics because generics are cheaper and preferred for cost-saving measures. However, in some cases, a brand name might be more widely recognized and prescribed initially.

Choice A rationale

Metoprolol is a beta-blocker used for hypertension and angina, not for controlling blood sugar levels.

Choice B rationale

Glucagon is used to treat severe hypoglycemia by increasing blood glucose levels, not for regular blood sugar control.

Choice C rationale

Metformin is an oral hypoglycemic agent used to lower elevated blood glucose levels in type 2 diabetes.

Choice D rationale

Nitroglycerin is a nitrate used to treat angina by dilating blood vessels, not for blood sugar control.
