Which abbreviation would be used to indicate a patient has a fracture?

The abbreviation "FX" is commonly used in medical contexts to indicate a fracture. This term derives from the Latin word "fractura," meaning to break or to fracture, which is why it is specifically associated with bone injuries. Using "FX" in medical documentation allows healthcare providers to communicate the condition of a patient's fractured bone quickly and efficiently.

In contrast, the other abbreviations serve different purposes. "HX" refers to history, often used to document a patient's medical history. "C/O" means "complains of," which is utilized to report symptoms a patient is experiencing. "ABG" stands for arterial blood gas, a test that measures the levels of oxygen and carbon dioxide in the blood.

Thus, when referring specifically to a fracture, "FX" is the appropriate and widely accepted abbreviation to use in medical settings.
