In healthcare documentation, what unit does the abbreviation "U" refer to?

The abbreviation "U" in healthcare documentation refers to "Unit." This term is widely used in medical settings to quantify medication dosages and other measurements. For example, when documenting the administration of insulin, you might see a dosage indicated with "U" to specify the number of units given to the patient. Using this standard abbreviation helps ensure clarity and uniformity in medical records, allowing for accurate communication among healthcare providers. Misinterpreting or misusing abbreviations, however, can lead to medication errors, which is why understanding these terms is vital in healthcare.
