Final answer:
The patient behavior that indicates learning occurred in the affective domain for a patient with diabetes mellitus is the patient's discussion on which foods must be avoided. This reflects a psychological commitment and personal value placed on dietary management, which is important in ongoing diabetes care.
Step-by-step explanation:
When assessing whether a patient with diabetes mellitus has learned effective dietary management in the affective domain, the nurse looks for changes in the patient's attitudes, values, and feelings towards their diet. The affective domain involves the psychological and emotional aspects of learning, which are critical in managing chronic conditions such as diabetes. Patient behavior that indicates learning in the affective domain includes expressing positive feelings about the diet or demonstrating a strong, personal commitment to following the dietary plan.
The correct patient behavior indicating that learning in the affective domain has occurred is option A: Discusses which food on the ordered diet must be avoided. This behavior suggests that the patient has processed the information on a deeper level, evaluating and internalizing the importance of diet in managing diabetes, which goes beyond simply demonstrating skills or knowledge attainment (such as in administering insulin correctly). The patient's ability to engage in a conversation on dietary choices highlights their understanding and commitment to their health, reflecting the goals of behavioral interventions in diabetes education.
