What is the primary focus of the history and review of systems?

• A. Laboratory results
• B. Imaging interpretations
• C. Questions about major body systems
• D. Physical examination maneuvers

Answer: (C)

The main concept is that history and review of systems gather what the patient reports about symptoms across the major body systems, rather than relying on test results or the examiner’s hands-on maneuvers. In the history and ROS, clinicians ask structured questions to uncover current or recent problems in areas like cardiovascular, respiratory, gastrointestinal, neurological, and other systems, guiding what to investigate next. This information comes from the patient’s subjective experience—pain, fatigue, shortness of breath, dizziness, weight changes, and similar symptoms—so it helps map the clinical picture before physical findings or tests are considered. Laboratory results and imaging interpretations are objective data from tests, and physical examination maneuvers are part of the exam itself, not the patient-reported symptom review.
