Nurses need compassion in order to empathize with their patients. It is impossible to fully understand exactly how every patient is feeling all the time, but you must appreciate they are having a difficult time and that they need someone to care. If you are unable to be caring and simply be there for someone, you should probably not try to be a nurse. This is just common sense. In particular, hospice nurses and ICU nurses should expect to see patients in the hardest times of their lives.
