In regards to the exercise of being able of the nurse, a reproduction of the medical power is observed, where ' ' head of enfermagem' ' , most of the time he adopts an arrogant leadership of autocratic nursing and in the command of the nursing team, what he infers Padilha (1997). On the other hand, as for the relations of being able of the nurse next to the nursing team, an alternation of papers is verified, that is, these assumes attitudes of authority, responsibility and requirement in the fulfilment of the duties, fellow creatures to those of the doctors. The exercise of the power carried through for the nurse is based on the knowledge of the administration in nursing. Maximiano (2005) it appraises to manage as the process to take decisions on objectives and use of resources. This knowledge consolidated through the Nightingaleano model and of the administrative theories, amongst which if it detaches the beginning of the Classic and Scientific School that, as Fernandes and Spagnol (2003) bring as characteristic the spalling of the activities, the impessoalidade in the relations, the centralization of the power and the rigid hierarchy, what it can be observed through the authoritarian managemental behavior adopted by the nurses.
Ahead of the diversity of subjective acquired by the professional nurse, where the conquest is substituted by the responsibility and the freedom is imprisoned the limitation, it allows the professional, to half acquire and methods for attainment of the procedural character of autonomy in the nursing. Spagnol (2003), still infers that although the contributions of the classic model of management, the organization of the work in the hospital area, throughout the time have produced effect negative, which harm the work process. The author still cites the difficulties in taking care of readily to the necessities of the customers and the workers, what she intervenes with the quality of the given services, therefore the work is developed mechanically, without bonds with the customers and the professionals of the daily one.
