What Inori wrote boils down to this: Your job as a nurse is to make a difference. By that, I mean that as a result of meeting YOU, he ends up better able to deal with a broken arm, and is free of any complications of the treatment of a broken arm (ie. no compartment syndorem, no infection at pain sites, etc. )
To do this, you need to first perfrom a comprehensive assessment that evaluates the FULL impact of this health event on his life: Is he right or left handed? Live alone? Will he be able to cook, shop, care for himself with one arm? Does he have a job that requires two hands? Is he at risk of losing it if he misses work? How will this affect his life roles? Will it have any ripple effects for his family? What if he is a caregiver for young children, or for an ill elderly person in his family, etc.
What led to the fracture? Are there environmental safety issues (unsafe stairs, slippery walk, etc.) that need to be addressed? Is he a heavy drinker?
How is he coping with this? Does he have a past history of recovering from an injury? Does he know what kind of diet best promotes bone healing?
What helps the pain? What makes it better or worse? Does he know how to care for a cast or pins? does he know the s/s of compartment syndrome and what to report? Will he need PT to regain full use of his arm?
According to the ANA, the defintion of Nursing is "The protection, promotion, and optimization of health and abilities, prevention of illness and injury, alleviation of suffering through the diagnosis and treatment of human response, and advocacy in the care of individuals, families, communities, and populations."
I know that a lot of students think the words in this defintion mean little in reality. They see it as something they have to memorize for school, but don't take the time to think deeply about what it actually says, and what it means for them personally. Those who do take it to heart are more likely to recognize the depth and power or nursing, and to act on the many, many possibilities in this situation. By engaging with the person more fully and by thinking in a truly holistic way, nurses recognize their many ways in which nurses can improve the lives of patients.
I guess what I am trying to say is to take in the bigger lessons about the unique way that nurses interact with patients, and work to make part of what you do. Broaden your point of view, and this process will be easier and make far more sense. It will also make you a far better nurse.
