Which item should be logged into the patient data system before the sleep study?

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

Answer: (B)

The essential point is that every sleep study needs a unique identifier to tie all data to the correct patient and specific study in the data system. The study identification number acts as the primary key, ensuring that recordings, notes, and results are accurately attributed to the right patient and study order. Logging this ID before the study starts prevents data mix-ups, makes data retrieval straightforward, and supports accurate reporting and cross-session comparisons. Other items like time of arrival, medical history, or nicotine timing are important for care and interpretation, but they do not provide the unique linkage that the study identification number guarantees.
