1. According to AASM guidelines, which combination of features is required to score an epoch as Stage REM? → Low-amplitude mixed-frequency EEG + rapid eye movements + low chin EMG
2. What is the role of benchmarking in establishing best practices? → Comparing performance against top performers to identify improvement opportunities
3. Alpha rhythm is defined as EEG activity in the frequency range of: → 8–13 Hz
4. What is the primary goal of quality assurance in professional practice? → To ensure consistent delivery of products or services that meet established standards
5. Sawtooth waves during polysomnography are most commonly associated with which sleep stage? → REM
6. What characterizes a high-performing team? → Clear goals, mutual trust, open communication, and shared accountability
7. What is the most important element of effective professional communication? → Clarity and accuracy of the message tailored to the audience
8. Why is continuous improvement important in quality management? → Because standards evolve, competitors improve, and customer expectations change
9. What does "informed consent" require in professional practice? → Providing complete, understandable information so individuals can make voluntary decisions
10. K-complexes are most prominently identified in which EEG derivation? → Frontal (F3/F4)
11. What is the purpose of a risk register? → To document, track, and manage all identified risks throughout a project or operation
12. Why is data visualization important in professional reporting? → It makes complex data more accessible and easier to understand quickly
13. Why is confidentiality important in professional practice? → It protects sensitive information and maintains trust between professionals and clients
14. What is the primary purpose of data analysis in professional practice? → To transform raw data into actionable insights for decision-making
15. In PSG signal digitization, aliasing occurs when: → The sampling rate is less than twice the highest frequency of interest
16. What is active listening in a professional context? → Fully concentrating, understanding, responding, and remembering what is being said
17. What role does continuing education play in maintaining certification? → It ensures professionals stay current with evolving standards and practices
18. When applying core principles in practice, what should be the first consideration? → Safety and compliance with established standards
19. When facing an ethical dilemma, what is the recommended first step? → Identify all stakeholders affected and review applicable codes of conduct
20. Mixed frequency low-amplitude EEG combined with low chin EMG tone defines which sleep stage? → REM
21. Which quality management tool is used to identify the most significant factors in a dataset? → Pareto chart (80/20 rule)
22. What role do key performance indicators play in strategic implementation? → They provide measurable benchmarks to track progress toward strategic objectives
23. What is the Plan-Do-Check-Act (PDCA) cycle used for? → Continuous improvement of processes and practices
24. The common mode rejection ratio (CMRR) of a PSG amplifier is important because it: → Rejects electrical noise shared by both recording electrodes
25. Which sleep-related breathing disorder involves cessation of both airflow and respiratory effort? → Central sleep apnea
26. What constitutes a conflict of interest in professional practice? → When personal interests could improperly influence professional judgment
27. What is the minimum duration a K-complex must meet to satisfy AASM scoring criteria? → 0.5 seconds
28. When should an epoch be scored Stage N3 rather than N2 even if sleep spindles are present? → When ≥20% of the epoch consists of slow wave activity
29. What distinguishes Stage N1 from Stage Wake in a subject who generates occipital alpha rhythm? → Alpha activity present for <50% of the epoch
30. Sleep-related hypoventilation is defined by AASM as arterial PCO2 (or surrogate) exceeding: → 50 mmHg during ≥25% of total sleep time
