1. Which of the following rhythms would be MOST concerning in a patient who is 100% pacemaker-dependent? → Pacemaker spikes without capture (failure to capture)
2. A patient receiving IV potassium replacement is on continuous cardiac monitoring. The CMT should monitor for: → Peaked T waves and widened QRS
3. How should a CMT professional handle a situation where quality assurance & performance improvement protocols conflict with practical constraints? → Document the conflict and seek guidance from appropriate authorities
4. Which of the following is a common symptom of cardiac arrhythmia? → Dizziness and palpitations.
5. What is a common challenge professionals face when applying quality assurance & performance improvement principles in Certified Cardiac Monitor Technician? → Balancing theoretical knowledge with practical application
6. Which quality improvement method is most applicable to professional ethics & legal compliance in Certified Cardiac Monitor Technician? → Plan-Do-Check-Act (PDCA) continuous improvement cycle
7. What is the main treatment for atrial fibrillation in many cases? → Rate control and anticoagulation therapy.
8. How does continuing education relate to professional ethics & legal compliance for CMT certified professionals? → It ensures professionals stay current with evolving standards and best practices
9. On a rhythm strip, a pacemaker spike is visible but is NOT followed by a P wave or QRS complex. This is called: → Failure to capture
10. High-quality CPR is BEST defined as: → Compressions at 100–120/min, depth ≥2 inches, full recoil, minimal interruptions
11. What is the significance of a 'pacemaker spike' artifact on an ECG? → It represents the electrical pulse delivered by the pacemaker generator
12. Which electrolyte imbalance most significantly increases a patient's risk of digoxin toxicity? → Hypokalemia
13. During a code, the CMT observes the rhythm change from VF to a slow wide-complex rhythm. The team should be informed that this may represent: → Agonal rhythm (idioventricular) suggesting poor perfusion
14. Which technology trend is most likely to impact communication & interprofessional collaboration in the CMT field in coming years? → Digital tools for enhanced data collection, analysis, and reporting
15. What is the primary advantage of a DDD pacemaker over a VVI pacemaker? → It maintains AV synchrony by pacing both chambers
16. Which quality improvement method is most applicable to communication & interprofessional collaboration in Certified Cardiac Monitor Technician? → Plan-Do-Check-Act (PDCA) continuous improvement cycle
17. When a cardiac monitor technician identifies ventricular fibrillation on a remote telemetry unit, the FIRST action is to: → Notify the bedside nurse or charge nurse immediately
18. Which of the following is used to monitor a patient's heart rate during cardiac monitoring? → Electrocardiogram (ECG).
19. What does a pulse oximeter measure? → Oxygen saturation levels.
20. What does the term 'lower rate limit' refer to in pacemaker programming? → The slowest rate at which the pacemaker will allow the heart to fall before pacing
21. IV lidocaine is used in the acute management of which condition? → Ventricular arrhythmias
22. Which arrhythmia is characterized by a rapid and irregular heart rate, often over 100 bpm? → Atrial fibrillation.
23. A patient's ECG shows flattened T waves and prominent U waves. Which electrolyte abnormality does this most suggest? → Hypokalemia
24. When implementing communication & interprofessional collaboration practices, what should a CMT professional prioritize first? → Compliance with established standards and protocols
25. What is the significance of peer review in quality assurance & performance improvement for CMT professionals? → It promotes accountability, knowledge sharing, and quality improvement
26. What is the primary purpose of a rate-responsive (DDDR or VVIR) pacemaker? → To automatically increase pacing rate in response to physical activity
27. What is the purpose of a pacemaker in cardiac monitoring? → To regulate heart rhythm.
28. Which electrolyte replacement is the antidote for torsades de pointes? → IV magnesium sulfate
29. Which technology trend is most likely to impact quality assurance & performance improvement in the CMT field in coming years? → Digital tools for enhanced data collection, analysis, and reporting
30. Which technology trend is most likely to impact evidence-based practice & research methods in the CMT field in coming years? → Digital tools for enhanced data collection, analysis, and reporting
