An older adult client has been asked to participate in a randomized controlled trial (RCT) related to the development of a new psychotropic medication. The nurse responsibly acts as the client's advocate when:
Correct Answer: D
Rationale: The correct answer is D because assessing the client's understanding is crucial to ensure informed consent and autonomy. By assessing the client's comprehension, the nurse can verify if the client is aware of the potential risks, benefits, and procedures involved in the RCT. This step is essential to uphold the client's rights and ensure they make an informed decision.
Choice A is incorrect because it does not address the importance of assessing the client's understanding and may provide false reassurance. Choice B is incorrect as it only focuses on explaining risks without assessing the client's comprehension. Choice C is incorrect as educating the family does not ensure the client's understanding and involvement in decision-making.
