1. What is the primary purpose of conducting a safety audit in Dysrhythmia Certification practice? → To identify and mitigate potential hazards
2. In the NASPE/BPEG pacemaker nomenclature code, what does the first letter represent? → Chamber(s) paced
3. The lower rate limit (LRL) in pacemaker programming is defined as: → The minimum heart rate below which the pacemaker will begin pacing
4. The AV delay in a dual-chamber pacemaker is typically programmed to which range? → 120–200 ms

7. Which ECG change is commonly associated with hypokalemia? → Flattened or inverted T waves
8. What is the importance of staying current with trends in Pharmacology & Drug Administration for Dysrhythmia Certification? → It ensures practices remain effective and relevant
9. Where should defibrillator pads be placed for standard anterior-lateral positioning? → Right upper chest below the clavicle and left lower lateral chest
10. What is the recommended paddle pressure when using hard paddles for manual defibrillation? → 25 pounds
11. Which of the following rhythms is considered a medical emergency due to its lack of cardiac output? → Ventricular Fibrillation

22. When a Dysrhythmia Certification professional discovers a regulatory violation, what is the appropriate action? → Report it through proper channels immediately
23. When a magnet is applied over a permanent pacemaker, the expected response is: → Asynchronous (fixed-rate) pacing regardless of intrinsic activity
24. What is benchmarking in the context of Dysrhythmia Certification quality management? → Comparing performance against best practices or competitors
25. When a magnet is applied over an implantable cardioverter-defibrillator (ICD), the primary effect is: → Tachyarrhythmia detection and shock therapy are suspended
