About This Quiz

There are different types of disorders that a person may be suffering from and one of the ways to diagnose them is by reading the brain waves of a patient, their eyes movement or heart rate using the polysomnography exam. Below is a practice exam Sample Sleep Exam #1 – on polysomnography for the BRPT. Give it a try and see how prepared you are.

    A patient's EKG tracing shows an irregular R-R rhythm without alterations to the P, QRS, and T waves. Which of the following arrhythmias fits this description?

    • Premature atrial contractions

    • Third Degree AV block

    • Sinus arrhythmia

    • Second Degree AV block

    Correct Answer
    A. Sinus arrhythmia
    Explanation
    Sinus arrhythmia is the correct answer because it is characterized by an irregular R-R rhythm without any alterations to the P, QRS, and T waves. In sinus arrhythmia, the heart rate varies with respiration, leading to irregularity in the R-R intervals. This is a normal finding and commonly seen in young individuals, especially during inspiration. It is important to differentiate sinus arrhythmia from other arrhythmias such as premature atrial contractions, which would show abnormal P waves, or AV blocks, which would show alterations in the conduction of the electrical impulses.

    Which of the following physiological signals is not typically measured during a polysomnography (sleep study)?

    • Brain waves

    • Eye movements

    • Blood glucose levels

    • Oxygen levels in the blood

    Correct Answer
    A. Blood glucose levels
    Explanation
    Polysomnography is a comprehensive test that monitors various physiological signals during sleep to diagnose sleep disorders. It typically records brain waves (EEG), eye movements (EOG), heart rate, muscle activity (EMG), breathing patterns, and oxygen levels in the blood (through a pulse oximeter). Blood glucose levels, however, are not part of standard polysomnographic measurements, as they do not directly impact the sleep assessment process. Instead, blood glucose monitoring is relevant to conditions like diabetes, which are outside the scope of a sleep study.

    According to accepted sleep scoring standards, if other scoring criteria are met, which of the following activities would be considered an event when each is 0.5 seconds in duration? 1. PLM 2. Arousal 3. Spindle 4. K-Complex

    • 1, 2, and 3 only

    • 1, 2, and 4 only

    • 1, 3, and 4 only

    • 2, 3, and 4 only

    Correct Answer
    A. 1, 3, and 4 only
    Explanation
    In accepted sleep scoring standards, if other scoring criteria are met, PLM (Periodic Limb Movement), Spindle, and K-Complex activities that are 0.5 seconds in duration are considered events. Arousal activity, on the other hand, is not considered an event in this case.

    The vertical position of the pens with the polysomnograph amplifiers turned off is referred to as:

    • Mechanical baseline

    • Electrical baseline

    • Time axis

    • Frequency response curve

    Correct Answer
    A. Time axis
    Explanation
    The vertical position of the pens with the polysomnograph amplifiers turned off is referred to as the time axis. This term describes the position on a graph where time is represented along the vertical axis. The time axis is used to measure and analyze the duration and timing of various events or signals in a given system or experiment.
