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 arrhythmiaExplanation
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.Rate this question:

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 axisExplanation
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.Rate this question:

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 levelsExplanation
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.Rate this question:

The narcolepsy tetrad includes all the following except
-
Excessive daytime sleepiness
-
Nocturnal myoclonus
-
Cataplexy
-
Sleep paralysis
Correct Answer
A. Nocturnal myoclonusExplanation
The narcolepsy tetrad consists of four main symptoms associated with narcolepsy: excessive daytime sleepiness, cataplexy, sleep paralysis, and hypnagogic hallucinations. Nocturnal myoclonus, on the other hand, is not a symptom commonly associated with narcolepsy. It refers to sudden, involuntary muscle jerks or twitches that occur during sleep. While it is a sleep-related movement disorder, it is not considered part of the narcolepsy tetrad.Rate this question:
