c/o stands for?

• A. Complains of
• B. Care of
• C. Conditions of
• D. Chief of

Answer: (A)

In patient documentation, c/o is used to record what the patient reports feeling or experiencing. It stands for “complains of.” So if a note says “c/o chest pain,” it means the patient reports chest pain. This is subjective information provided by the patient, not a confirmed diagnosis yet. In other contexts, c/o can mean “care of” (like mailing addresses), but in medical charting the intended meaning is “complains of,” which is why this is the best choice.
