In contrast, Gerald Caplan's theory of crisis intervention describes a rationale for dealing with certain psychiatric patients. Together, these two theories may help define the interaction between nurses and their patients.
Dorothea Orem's General Theory of Nursing--The Idea:
Dorothea Elizabeth Orem was a preeminent nursing theorist whose concepts direct nursing practice. Her general theory of nursing describes the profession as a complex form of deliberate interpersonal action. Nurses should ultimately provide a therapeutic human health service. Orem's theory specifically focuses on the nurse's approach towards persons who are limited in their ability to take care of themselves (Fawcett, 1995, pp. 277-374). According to Orem (cited in Humphreys, 1995, pp. 9-11), "individuals take actions to meet others' health-related needs" (Humphreys, 1995, pp. 9-11). Dependent care consists of those actions which people
