What does the abbreviation "c/o" stand for in a medical context?

In a medical context, the abbreviation "c/o" stands for "complains of." This term is commonly used in clinical settings to indicate what symptoms or issues a patient is reporting. For example, a healthcare professional may write "patient c/o headache," meaning the patient is expressing that they have a headache. This shorthand is essential for documenting patient reports and ensuring clear communication among healthcare providers regarding a patient's condition.

The other options, while they might appear relevant in different contexts, do not accurately reflect the standard meaning of "c/o" in medical terminology. "Constant observation," "care of," and "case of" are not the recognized interpretations for this specific abbreviation and are less commonly used in patient documentation. Understanding these abbreviations is crucial for anyone working in healthcare to facilitate effective communication and documentation.
