The importance of the history and physical must not be understated, but the data often obtained from these activities are subjective or dependent on the patient and the stage of the condition. Furthermore, the signs and symptoms of many diseases are similar, so much so, that patients can be misdiagnosed or mismanaged without additional data. Consider, for example, the number of disorders that can cause the fatigue and weight loss reported by the patient in Case 7-1. Is the shortness of breath and chest pain reported in Case 7-2 due to a cardiac or respiratory problem?
