Clinical Medical Assistant Certification Exam Practice Question
A differential diagnosis is based on which of the following?
Correct Answer: B
Rationale: A differential diagnosis involves comparing symptoms of similar diseases to identify the correct condition affecting the patient. This process requires a thorough analysis of various disease presentations, making option B the most accurate choice.
Option A is incorrect because while tissue data can provide valuable insights, it is not the sole basis for differential diagnosis. Option C is misleading; external examinations alone are insufficient without considering patient history and symptoms. Option D focuses solely on symptoms, neglecting the importance of comparing them across different diseases. Option E is also wrong, as stressed lesions may be relevant but do not encompass the broader diagnostic process needed for accurate assessment.
