Which task must be completed before beginning a PSG according to the material?

• A. The patient signs a consent form
• B. Biocalibrations are performed by the tech
• C. A pre-sleep questionnaire is completed by the patient
• D. A beverage is given

Answer: (A)

Obtaining informed consent before starting a polysomnogram is essential. The consent form confirms that the patient understands what will happen during the study, what data will be collected, any potential risks or discomfort, and the patient’s right to withdraw. This protects patient autonomy and provides legal and ethical authorization for the procedure. While other steps like completing a pre-sleep questionnaire or performing sensor biocalibrations occur as part of preparation, they do not substitute for the mandatory consent. A beverage is not a required or standard pretest step for initiating the PSG.
