1What is the primary purpose of the STOP-BANG questionnaire in sleep medicine?

A.To diagnose narcolepsy in pediatric patients

B.To screen for obstructive sleep apnea risk

C.To assess restless leg syndrome severity

D.To evaluate REM sleep behavior disorder

Explanation: The STOP-BANG questionnaire is a validated screening tool used to identify patients at high risk for obstructive sleep apnea (OSA). It evaluates Snoring, Tiredness, Observed apnea, blood Pressure, BMI, Age, Neck circumference, and Gender. A score of 3 or more indicates high risk for OSA. It is not designed for narcolepsy, RLS, or RBD assessment.

2A patient reports an Epworth Sleepiness Scale score of 15. What does this indicate?

A.Normal daytime alertness

B.Mild daytime sleepiness

C.Moderate daytime sleepiness

D.Severe daytime sleepiness

Explanation: The Epworth Sleepiness Scale (ESS) scores range from 0-24. Scores of 0-10 are considered normal, 11-12 indicate mild sleepiness, 13-15 indicate moderate sleepiness, and 16-24 indicate severe sleepiness. A score of 15 suggests moderate excessive daytime sleepiness that warrants further evaluation for sleep disorders such as sleep apnea or narcolepsy.

3Which of the following medications should be documented as potentially affecting sleep architecture?

A.Antihistamines with sedating properties

B.Beta-blockers

C.Selective serotonin reuptake inhibitors (SSRIs)

D.All of the above

Explanation: All of these medications can affect sleep architecture. Sedating antihistamines can increase sleepiness and affect REM sleep. Beta-blockers may cause insomnia, nightmares, and reduce melatonin secretion. SSRIs can suppress REM sleep, cause sleep fragmentation, and may lead to REM behavior disorder in some patients. A comprehensive medication history is essential for accurate sleep study interpretation.

4What is the minimum recommended abstinence period from caffeine before a sleep study?

A.2 hours

B.4 hours

C.8 hours

D.12 hours

Explanation: Patients should abstain from caffeine for at least 4 hours before a sleep study, though many sleep centers recommend avoiding caffeine after noon on the day of the study. Caffeine is a stimulant that can delay sleep onset, reduce sleep efficiency, and affect sleep architecture, potentially compromising the diagnostic quality of the polysomnogram.

5During the pre-study interview, a patient mentions they work rotating shifts. How should this information affect the sleep study scheduling?

A.No adjustment is needed; proceed with standard scheduling

B.Schedule the study during their usual sleep period

C.Reschedule for a weekend only

D.Cancel the study until they have a fixed schedule

Explanation: For shift workers, the sleep study should be scheduled during their usual sleep period, even if this means conducting the study during daytime hours. This ensures the study captures their typical sleep patterns and any sleep disorders that may be present. Many sleep labs offer daytime studies specifically for shift workers to accommodate their schedules.

6What information is essential to obtain from a patient before obtaining informed consent for a polysomnogram?

A.Only the purpose of the test

B.Purpose, procedures, risks, benefits, and right to refuse

C.Purpose and cost of the test

D.Only the risks associated with the test

Explanation: Informed consent requires that patients understand the purpose of the polysomnogram, what procedures will be performed, potential risks and discomforts (such as skin irritation from electrodes), benefits of the testing, and their right to refuse or withdraw from the study at any time without penalty. This is both an ethical and legal requirement.

7Which comorbid condition would require special consideration during a sleep study due to increased risk of cardiac events?

A.History of severe congestive heart failure

B.Seasonal allergies

C.Mild eczema

D.History of appendectomy

Explanation: Severe congestive heart failure (CHF) requires special consideration during sleep studies because sleep apnea can trigger arrhythmias, nocturnal angina, or acute decompensation. The technologist should be prepared to monitor for signs of cardiac distress and may need to communicate with on-call medical staff. Seasonal allergies, eczema, and appendectomy history do not pose the same level of risk during sleep testing.

8How long should a patient maintain a sleep diary before a diagnostic polysomnogram?

A.1-2 days

B.3-7 days

C.2-4 weeks

D.6-8 weeks

Explanation: Sleep diaries are typically maintained for 2-4 weeks to capture the patient's typical sleep-wake patterns, including weekends and weekdays. This duration provides sufficient data to identify circadian rhythm disorders, insomnia patterns, or sleep schedule irregularities that may affect study interpretation or treatment planning.

9According to the International 10-20 system, where is the C3 electrode positioned?

A.3 cm from the vertex on the right side

B.At the vertex of the scalp

C.3 cm from the vertex on the left side

D.At the occipital protuberance

Explanation: In the International 10-20 system, C3 is positioned 3 cm from the vertex (Cz) on the left side of the head. The "C" designates the central region, and odd numbers indicate the left side of the head. C4 would be the corresponding position on the right side. These central positions overlie the sensorimotor cortex and are essential for EEG monitoring during sleep staging.

10What is the recommended impedance threshold for EEG electrodes during a polysomnogram?

A.Less than 5 kΩ

B.Less than 10 kΩ

C.Less than 20 kΩ

D.Less than 50 kΩ

Explanation: The recommended impedance threshold for EEG electrodes is less than 10 kΩ (ideally less than 5 kΩ). Higher impedance can result in increased electrical interference, poor signal quality, and artifact. Technologists should check impedance values after electrode application and troubleshoot any electrodes showing readings above acceptable thresholds before beginning the study.
