A nurse is contributing to the plan of care for a client who has major depressive disorder. Which of the following recommendations should the nurse include in the plan of care?

A. Suggest the client exercise before going to bed: Exercising close to bedtime can interfere with sleep and worsen insomnia, which is often present in clients with depression. Morning or early afternoon exercise is preferable for mood enhancement and energy regulation. B. Encourage the client to use positive self-talk: Positive self-talk helps the client challenge negative thought patterns, improve self-esteem, and reduce depressive symptoms. Cognitive-behavioral interventions like this are evidence-based strategies in managing major depressive disorder. C. Recommend the client spend time alone in his room: Isolation can worsen depressive symptoms and feelings of loneliness. Encouraging social interaction, participation in activities, and therapeutic engagement is more beneficial for recovery. D. Offer the client low-protein snacks throughout the day: Protein intake is important for energy and neurotransmitter synthesis. Low-protein snacks do not provide nutritional support and are not specifically indicated for depression management.
