In recent decades the tasks of a nurse in the scope of prevention of arterial hypertension (AH) has been considerably complicated
and become valuable, which requires extending and improving professional competence and professional-personality aspects in
particular. Meanwhile, studies focused on the distinguishing relevant factors of professional-personality competence (PPC) of a
nurse preventing AH are lacking. Analysis of the answers of nurses on the questionnaire enabled to distribute all the respondents
into three groups concerning their complete and correct awareness of the bases of preventive work with AH patients: 1) inadequate
level – 22%, 2) relatively satisfactory level – 48%, adequate level – 30%. System-forming factors of the professional-personality
competence of nurses were developed considering their utmost correlation workload. The patterns suggested represent the level of
sociability, empathy, optimism and lack of self-confidence as the most relevant factors in the scope of implementation of tasks
concerning AH prevention by the nurses of the Therapeutic Department. The patterns of competence can be used as working
structures focused on the staff, instruments of evaluation and design of advanced professional courses for nurses of a therapeutic
area.
