A nurse is teaching a client who has hypertension and a new prescription for a low-sodium diet. Which of the following teaching methods uses the cognitive domain?

Choice A reason: Reviewing strategies to reduce sodium intake engages the cognitive domain by requiring the client to understand, analyze, and apply knowledge about dietary choices. This involves learning about sodium content in foods, reading labels, and planning meals, which stimulates intellectual processes like comprehension and problem-solving, critical for managing hypertension through diet. Choice B reason: Observing the client choose low-sodium foods involves the psychomotor domain, as it requires physical action and decision-making based on learned knowledge. While it reinforces cognitive understanding, the primary focus is on the client’s behavior and application of skills, not intellectual processing, making it less directly aligned with the cognitive domain. Choice C reason: Demonstrating low-sodium meal preparation targets the psychomotor domain by focusing on physical skills and techniques for cooking. Although it may indirectly involve cognitive understanding, the primary emphasis is on performing the task, not analyzing or strategizing, which distinguishes it from a teaching method centered on the cognitive domain. Choice D reason: Providing a low-sodium recipe book supports the cognitive domain indirectly by offering resources for learning. However, it is a passive method that does not actively engage the client in analyzing or applying knowledge, unlike reviewing strategies, which requires active intellectual participation to understand and implement dietary changes for hypertension management.
