What is the most common cause of dementia?

A. Use nightlights and remove extra furniture from the room: Nightlights provide gentle lighting that can reduce disorientation, and removing extra furniture minimizes fall risk.
B. Place the patient in a room with another recovering patient. This might increase agitation and disrupt both patients' sleep.
C. Instruct the patient to orient himself to his surroundings at bedtime. This may not be effective due to the patient's disorientation during detoxification.
D. Wake the patient up every 4 hours to eat a small snack. Frequent waking can disrupt sleep patterns and increase confusion.

A. "Cellulitis can come back at any time." This statement reflects an understanding that cellulitis can recur, which indicates that the patient is aware of the potential for reinfection.
B. "My skin is cleared up. I don't think I need the medication anymore." Antibiotics should be taken for the full prescribed duration even if symptoms improve, to ensure complete eradication of the infection.
C. "Cellulitis is contagious." While cellulitis itself is not contagious, this statement does not necessarily indicate misunderstanding of antibiotic therapy.
D. "If I had washed that scratch with soap and water, I probably would not have gotten cellulitis." This reflects an understanding of preventative measures, although proper medical treatment is still required for existing cellulitis.
