Nursing in this theory is described as an art that helps people who need health care, and the goals are achieved by following a series of steps according to a model. The nurse and patient must work together in this process to achieve said goals. Interpersonal relationship theory is a process that begins with the roles of the nurse, and these roles began with the nurse as stranger, teacher, resource person, counselor, surrogate mother, and leader (Nursing Theories, 2012) . The theory begins with the role of the stranger, which is defined as the introductory phase and is an environment in which the patient meets the nurse and develops a trusting relationship. The nurse as teacher allows the nurse to provide knowledge and information on a particular interest while the resource person provides information specific to a problem or situation. As counselors, nurses help make life decisions and provide advice. The surrogate role acts as a patient advocate, while the leader role allows the nurse to take on most of the responsibility for helping patients follow treatment.
