Comparing Cues to Possible Diagnoses

Cues are analyzed in relation to possible diagnoses through a mental process of evaluation. Evaluation involves a process of mental matching wherein the existing cues are matched with the expected cues for the diagnoses being considered. Information about the expected cues for diagnoses is found in this book and current literature on specific phenomena such as pain, coping, and fluid volume. During the evaluation of cues and related diagnoses, nurses may decide that there is not enough evidence to make diagnostic decision or that there is enough evidence for one likely diagnosis. If a nurse decides that there are not enough data to make a diagnosis, the next step involves a focused search for additional cues. If a nurse decides that there is enough supporting evidence, a diagnosis is made and then validate.
