A nursing home facility hosts a weekly cocktail hour. You are a social
  worker on staff. At the last few parties, you notice a 69 year old
  woman who appears to be inebriated but has only one or two drinks.
 
  In a short discussion with her, she says she enjoys parties and social
  drinking among friends. What does the situation suggest?
  A. She must be drinking before the cocktail hour starts.
  B. She probably has been prescribed new or different medication
  that interacts with the alcohol.
  C. She is probably depressed, drinking more on her own time, and
  building a tolerance to alcohol.
  D. You need to perform a detailed assessment to determine the
  cause of the inebriation.
