Final answer:
A working diagnosis during the MDM process, which involves considering and ruling out multiple potential conditions, is called a differential diagnosis.
Step-by-step explanation:
A working diagnosis early in the Medical Decision Making (MDM) process as the physician evaluates signs, symptoms, and test results to ascertain the patient's final diagnosis is known as a differential diagnosis. This process involves considering multiple potential conditions that could be causing a patient's symptoms and methodically ruling out each option based on medical knowledge, laboratory tests, and imaging studies. Through this process, the physician narrows down the list of potential diagnoses to the most likely one.
