Describe the characteristics of nursing theory within the discipline of nursing.

CASE INTRODUCTION: The community health nurse knocked softly before
entering Isabel’s bedroom. On this home visit, Isabel was holding her
3-week-old baby girl, Pearl, while 2-year-old Jerry was sitting on the
floor playing with a cat. In one corner, a full litter box sat on the
floor next to the changing table. The nurse noted two half empty 4-oz
formula bottles on the changing table, an empty box of baby wipes, and
three soiled cloth diapers. Looking into Pearl’s sleeping face, Isabel
said “She’s finally fell asleep. I am so tire. Jerry, stop teasing
Freckles (the cat) and come over here and hold Pearl while I get
something to drink. Do you want something to drink?” The nurse quickly
scanned the room and saw an unmade bed with a bassinet wedged against
the wall. Jerry’s bed, also unmade, was in the corner opposite the
litter box. The small bedroom was stifling hot, the ceiling fan was not
on, and the windows were closed. A table in the middle of the room had
plates with partially eaten sandwiches and half-finished cans of soda.  
      

1. Based on this case study how would the nurse
   practicing from Nightingale’s theory begin her home visit? What would be
   the priority for the nurse in this situation? 
2. How might Nightingale’s understanding of sanitation and environment guide the nurse in her home visit? 
3. How could the nurse develop a relationship with Isabel and return as a welcomed visitor in Isabel’s “home”?
