It is not uncommon to hear about lack of specification of nursing activities in Mental Health. This situation has been stressed now-a-days after emphasis has been given, to multiprofessional work, a really efficient system of assisting clients if and when every professional knows his specific share. Supported by this belief and by the known literature, we offer a suggestion of the activities in mental health especific of the nurse as well as of other activities in mental health especific of the nurse as well as of other activities which may be developed by other professionals.
