A nurse is caring for an older adult who is in the pre-trajectory phase of the Chronic Illness Trajectory. The nurse knows that this phase is characterized by which of the following:

A. Diagnostic testing being conducted: Diagnostic testing typically occurs during the trajectory onset phase, when symptoms begin to appear and the illness is being identified. The pre-trajectory phase occurs before the illness develops, so testing is not yet indicated. B. A period of temporary remission from the crisis: A remission phase takes place later in the trajectory, after diagnosis and treatment have begun. The pre-trajectory phase precedes the onset of symptoms, no remission or recovery period is present at this point. C. The absence of signs or symptoms of the illness: The pre-trajectory phase represents a stage where the individual is at risk for developing a chronic illness but has not yet manifested symptoms. The focus during this phase is on health promotion, prevention, and risk reduction to delay or prevent disease onset. D. A progressive decline in physical and/or mental status: Decline occurs during later phases of the chronic illness trajectory, such as the downward or dying phases. In contrast, the pre-trajectory phase involves maintaining health and preventing the start of illness rather than managing decline.
