A client tells the nurse I'm told that I should reduce the stress in my life, but I have no idea where
  to start.. The best suggestion for the nurse to make would be
 
  a. Why not start by learning to meditate? That technique will cover everything..
  b. In cases like yours, physical exercise works to elevate mood and reduce
  anxiety..
  c. Most stress is related to conflicts in interpersonal relationships. You can work on
  becoming more assertive..
  d. Keeping a journal can help you identify sources of stress by looking at activities
  that put a strain on energy or time or trigger anger or anxiety..
