In this paper, made up with a group of nurses from a governamental school hospital, the methodology used was that of the participating research, taking the praxis philosophy as a theoretic reference. The children hospitalization problem was discussed in the group throughout the principles of the democracy emphasising the admission. But other necessities arouse using the historical dialectical approaching. They will be studied continually. The critical analysis of the problem showed us that the nurses made a great progress individually or as a group, in their view of the reality. They gained a more reflexive and critical class conscience despite until begining.
