A nurse is preparing to teach pharmacology concepts to a group of students. The nurse should include which of the following?

The correct answer is A because alternative therapies refer to treatments that are not considered traditional or conventional methods of treatment. Biologics are derived from living organisms, such as plants, animals, and microorganisms, whereas alternative therapies typically do not involve living organisms. Biologics also go through extensive clinical testing before being approved, while alternative therapies may not have the same regulations. Choice B is incorrect because biologics are not primarily derived from plants but rather living organisms. Choice C is incorrect because biosimilar drugs do require clinical testing, although they may not have to go through the same amount of testing as the original biologic drug. Choice D is incorrect because therapeutics refers to the use of medications to treat and prevent diseases, whereas the question is specifically asking about teaching pharmacology concepts.
