The nurse is explaining the differences between uncontrolled and controlled substances.
Which of the following medications is a controlled substance?

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

Long-acting medications provide long-term control of symptoms but albuterol is short-acting.

Choice B rationale

Albuterol is not indicated for the treatment of nasal congestion.

Choice C rationale

Albuterol is an inhaled short-acting beta agonist used to prevent and treat bronchospasm in asthma.

Choice D rationale

Albuterol is not used for managing cold symptoms.
