Which abbreviation refers to a systematic examination of multiple body systems?

The abbreviation that refers to a systematic examination of multiple body systems is "ROS," which stands for "Review of Systems." This term is used in medical practice to describe a comprehensive assessment that involves going through various body systems to identify any potential issues or symptoms that the patient may have. Conducting a ROS allows healthcare providers to gather important information about the patient's health history and current state, providing a broader context for diagnosis and treatment.

In contrast, "Rx" typically refers to a prescription or treatment plan; "ROM" denotes "Range of Motion," which assesses joint mobility; and "SOB" means "Shortness of Breath," describing a specific symptom rather than conducting a broader evaluation across multiple systems. Therefore, "ROS" is the only option that accurately represents a systematic approach to examining various body systems.
