Several residents in a long term care facility have been diagnosed with herpes zoster. Which resident will require the closest observation for development of complications?

A. Nausea. Disulfiram causes an acute sensitivity to alcohol. When alcohol is consumed, it leads to an accumulation of acetaldehyde, causing unpleasant effects like severe nausea, vomiting, and headache, deterring the individual from drinking.
B. Blackouts. Blackouts are periods of memory loss due to heavy drinking but are not specifically induced by the combination of disulfiram and alcohol.
C. Hypertension. While disulfiram can cause cardiovascular effects, hypertension is not the primary or most severe side effect of consuming alcohol while on disulfiram.
D. Headaches. Headaches are indeed a part of the disulfiram-alcohol reaction, but the primary severe side effect leading to the aversion is nausea.

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.
