There are South American Nurses here really... i am one of them, i am from Lima Peru. Being a nurse in my country like others South American countries is very different than in U.S.A. i think. Here the nurse is responsible of the mayority of activities related to the health patient, in public hospitals a nurse can have 40- 45 patients in a unit and she have to assistents to work with, the nurse have to supervise the cleaning, the medication, the feeding, have to take the blood, urine samples,etc, have to take the better and quick actions when she thinks it is necessary, doctors come and check patients just for 10 minuets (average) and the rest of the day they have to come when we need it is necessary , nurses are responsible of the physical, pshycological and spiritual health of the patients, her/his families and also the community we live in.
Nurses in my country like others work many hours for earning few money, the minimum of hours that a nurse has to work here is 150 per month, but doing that you only can earn 1500 soles = $450 (american dollars/per month), it is difficult to live with this amount of money, because of that many of us have to work in two places and work 300 hours/per month aprox.
As a result, many of us are interested in working abroad, that is sad because we love our country and our people, but if you think in having a better quality of life and you know there are places where our human rigths can be respected that is why we choose a different option...working abroad.
