history: I work as a Paramedic and so I run on many different patients each shift. Each patient I run on, I always try to treat them as if they were my grandmother.  I work as a Paramedic and I try to approach each patient as if they were my grandmother.  That's wonderful! It sounds like you really care about each patient. 
current: I try to! It can be difficult sometimes which is why I try to have that mindset...
next: I bet! I bet that job would be a lot on your physically as well as mentally.
