Prior to the sleep study, which item should be logged into the patient data system to identify the session?

• A. Time of arrival
• B. Medical history
• C. Study identification number
• D. Time of last nicotine intake

Answer: (C)

The main idea is using a unique study identification number to tag and retrieve the specific sleep study session. This identifier links all data from that session—recordings, notes, reports, and scheduling—so everything stays correctly associated with the right patient and visit. It acts as the primary key in the data system, ensuring accurate retrieval, auditing, and cross-system consistency. Other details like time of arrival, medical history, or time of last nicotine intake provide clinical context but do not uniquely identify the session. They can vary or exist across visits and aren’t reliable for distinguishing one study from another, whereas the study identification number is purpose-built for that purpose.
