Which information should a nurse be sure to include when preparing discharge plans for a patient recently diagnosed with pernicious anemia?

A. Avoiding prolonged exposure to direct sunlight: This is a precaution for Lupus (SLE) or patients on photosensitizing drugs, not pernicious anemia. B. Providing sufficient rest periods throughout the day: Because anemia results in decreased oxygen-carrying capacity, patients experience significant fatigue. Pacing activities and resting helps manage this symptom. C. Adding a rigorous daily workout: A rigorous workout would increase oxygen demand beyond what the patient's blood can currently supply, leading to extreme exhaustion. D. Adding daily high-fat, low-fiber supplements: This has no therapeutic benefit for B12 deficiency and could lead to other health issues.
