It is to the nursing situation that the nurse brings self as caring person. It is within the nursing situation that the nurse comes to know the other as caring person, expressing unique ways of living and growing in caring. And it is in the nursing situation that the nurse attends to calls for caring, creating caring responses that nurture personhood. It is within the nursing situation that the nurse comes to know nursing, in the fullness of aesthetic knowing. The nursing situation comes into being when the nurse actualizes a personal and professional commitment to the belief that all persons are caring. It should be recognized that a nurse can engage in many activities in an occupational role that are not necessarily expressions of nursing. When a nurse practices nursing thoughtfully, that nurse is guided by his or her conception of nursing. The concept of nursing formalized in the Nursing as Caring theory is at the very heart of nursing, extending back into the unrecorded beginnings of nursing and forward into the future. Acknowledgement of caring as the core of nursing implies that any nurse practicing nursing thoughtfully is creating and living nursing situations because, whether explicit or tacit, the caring intent of nursing is present. Remember that the nursing situation is a construct held by the nurse, any interpersonal experience contains the potential to become a nursing situation. In the formal sense of professional nursing, the nursing situation develops when one person presents self in the role of offering the professional service of nursing and the other presents self in the role of seeking, wanting, or accepting nursing service. The nurse intentionally enters the situation for the purpose of coming to know the other as caring person. The nurse is also allowing self to be known as caring person. Authentic presence, like most human capacities, is inherent and can be more fully developed through intention and deliberate effort. Authentic presence may be understood simply as one's intentionally being there with another in the fullness of one's personhood. Caring communicated through authentic presence is the initiating and sustaining medium of nursing within the nursing situation.
