ROS stands for which term in patient assessment?

• A. Rate Of System
• B. Review of Symptoms
• C. Reference Of System
• D. Review of System

Answer: (D)

In patient assessment, ROS refers to a Review of Systems, a structured check where you ask the patient about symptoms across each body system (such as constitutional, cardiovascular, respiratory, GI, neuro, etc.). This step helps uncover symptoms the patient might not volunteer and guides further questioning, the physical exam, and management. Even though you may see slight wording variations, the idea is the same: a systematic review of symptoms by body system. Other phrases like Rate Of System or Reference Of System aren’t used in clinical practice.
