A 78-year-old male who underwent hip replacement surgery 2 days ago becomes increasingly agitated, disoriented, and hallucinates at night. During the day, he is lethargic but can follow commands. His vital signs are stable, and labs are unremarkable. What is the most appropriate initial management strategy?

✓ Correct Answer: Option C

This patient is experiencing post-operative delirium. The initial management for delirium focuses on non-pharmacologic interventions, including frequent reorientation, ensuring adequate hydration and nutrition, optimizing sensory input (glasses/hearing aids), and promoting good sleep hygiene. Identify and address underlying causes.
