What does TO/VO mean in clinical documentation?

• A. Time of observation
• B. Telephone Order
• C. Therapy Order
• D. Transcribed Order

Answer: (B)

In clinical documentation, TO/VO flags orders that come via telephone or spoken communication rather than being written directly by the physician. TO stands for Telephone Order, and VO stands for Verbal Order. These designations alert staff that the order originated through a phone call or a verbal instruction and may require prompt verification and a physician’s countersignature within a defined timeframe. That’s why the option representing Telephone Order fits best. Time of observation and Transcribed Order refer to different concepts, and Therapy Order is not the standard meaning for these abbreviations.
