Units and measures

cc

cubic centimeter

A volume equal to one milliliter. Recognize it in older records; the current preference is mL.

Error-prone, but not on the Official "Do Not Use" List. Handwritten cc has been misread as the letter u and from there as a unit, which is why mL is preferred and why cc is named on ISMP's error-prone abbreviation list — a different document from the Joint Commission one.

How it gets tested

A boundary item, and the boundary is the point: cc is widely discouraged but is NOT a row on The Joint Commission's Official "Do Not Use" List. A question asking which of several notations is on that list is testing whether you know the difference between "error-prone" and "on the list".
