Final answer:
The correct answer indicating a client's attainment of a cognitive skill is '1. Client explains that the medication should be taken with meals,' showcasing their capability to process, understand, and verbalize the taught information.
Step-by-step explanation:
The question the student is asking pertains to the evaluation of cognitive skills in patients, specifically in the context of client responses to teaching sessions in a healthcare setting. Cognitive skills involve the mental capabilities necessary for processing information, understanding language, and applying knowledge. In this scenario, the correct answer would be '1. Client explains that the medication should be taken with meals' as this response exemplifies a client's ability to recall and understand information provided during a teaching session and verbalize it back. This demonstrates attainment of a cognitive skill because the client has retained and comprehended the information (memory and understanding), can articulate it clearly (language and speech), and understands the context of its application (judgment and abstract reasoning).
Options 2, 3, and 4 relate more to psychomotor and practical skills rather than cognitive skills. Psychomotor skills involve the physical movements and actions guided by cognitive processing, but successful performance of these actions does not directly illustrate the cognitive comprehension that option 1 does. Evaluating cognitive skills requires assessing the patient's mental ability to process and understand information, which can then guide their actions. Therefore, the nurse can determine the client's attainment of cognitive understanding by hearing them explain the appropriate use of medication, indicating they have successfully learned and internalized the information presented.
