Review of systems (ROS) is described as which of the following?

• A. Captures more details per organ system, goes from head to toe
• B. Documents only major systemic complaints
• C. Reviews the past medical history in depth
• D. Is used only after the physical examination

Answer: (A)

The ROS is a systematic, head-to-toe inquiry that elicits symptoms across every organ system. It aims to gather more details per system than just the chief complaint, asking about a wide range of symptoms the patient may have experienced recently or in the past. This broad, symptom-oriented check helps uncover issues the patient might not spontaneously mention and guides the rest of the history and the physical examination. It’s a part of history-taking rather than a review of past medical history, and it’s typically done early in the visit rather than after the physical exam. In short, it captures comprehensive symptom details across body systems in an organized way.
