Which task is NOT required before beginning a PSG study?

• 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. The patient is given a beverage, which is put on the bed side table

Answer: (D)

Before starting a PSG, the focus is on safety and accurate data collection: obtaining informed consent, calibrating the recording equipment, and gathering relevant patient information through a pre-sleep questionnaire. Consent ensures the patient agrees to monitoring and understands any risks. Biocalibrations by the technologist are essential so that sensors for EEG, EOG, EMG, respiratory effort, oxygen saturation, and other measures provide true readings. A pre-sleep questionnaire helps identify factors that could influence sleep or interpretation, such as medications, prior sleep complaints, and daily habits. Giving the patient a beverage at the bedside is not part of standard pre-study requirements and doesn’t aid in data collection or safety, so it’s the task not required before beginning a PSG.
