Question 1 of 5
A group of nurses are discussing the difference of an agonist verses an antagonist. Which of the following medications may the nurse select as an agonist?
Correct Answer: D
Rationale: The correct answer is D. An agonist is a medication that activates the receptor activity. In this case, it activates the receptor activity and works synergistically with the receptor to produce a response. This is in contrast to an antagonist (choice
B) that blocks the receptor activity.
Choices A and C are incorrect because they do not describe the action of an agonist.
Choice A limits receptor activity, while choice C changes receptor activity but does not necessarily activate it.
Therefore, the correct choice is D as it aligns with the definition of an agonist.
