Exercise 3

A 67-year-old man recently lost his wife after being married for 42 years. He met his wife shortly after he returned from Vietnam as a combat soldier. He visits his physician and reports decreased appetite, moodiness, and extreme fatigue, even though he sleeps 10 to 12 hours a night. When giving his medical history, he admits that he drinks 4 or 5 beers and smokes marijuana almost every day.
For what safety issues is this older adult at risk and why?
