When assessing a patient with a medical complaint, which of the following would MOST likely reveal the cause of the problem?

• A. Baseline vital signs
• B. Primary assessment
• C. Medical history
• D. Index of suspicion

Answer: (C)

Starting with the main idea: you uncover the cause of a patient’s complaint most effectively by obtaining a thorough medical history. What a patient has experienced before—past illnesses, current medications, allergies, recent events, and how the symptoms started and evolved—often points directly to the underlying problem. This information gives you the context that physical findings and vital signs alone cannot provide, because those data reflect the body’s current status rather than why that status is happening. Baseline vital signs tell you what the body is doing right now, not why it’s doing it. Primary assessment focuses on identifying and addressing life threats, not on uncovering etiology. The index of suspicion is a clinician’s educated expectation about possible causes, guiding what you look for, but it doesn’t by itself reveal the cause. In contrast, the medical history supplies the connections between patient history and current symptoms, helping you pinpoint the most likely source of the problem.
