A Holter monitor is best used to detect:
Answer: Intermittent arrhythmias not captured on a routine 12-lead ECG
Holter monitors provide 24–48 hours of continuous ECG recording, making them ideal for correlating symptoms with transient arrhythmias in ambulatory patients.
What MET level is generally considered safe for most discharge activities after an uncomplicated myocardial infarction?
Answer: 3-5 METs
Activities of 3-5 METs, such as slow walking and light household tasks, are generally appropriate at hospital discharge after an uncomplicated MI.
The original Borg Rating of Perceived Exertion (RPE) scale ranges from:
Answer: 6 to 20
The original Borg RPE scale ranges from 6 to 20, where 6 represents no exertion and 20 represents maximal exertion, values that roughly correspond to heart rate when multiplied by 10.
Which personal protective equipment (PPE) principle applies to ALL CCT certified professionals regardless of their specific role?
Answer: PPE must be properly fitted, maintained, and replaced as needed
Regardless of experience level, PPE must be properly fitted, regularly maintained, and replaced when worn or damaged.
What is the typical target heart rate range recommended during Phase II cardiac rehabilitation?
Answer: 60-80% of heart rate reserve
Phase II cardiac rehabilitation targets 60-80% of heart rate reserve using the Karvonen formula to achieve cardiovascular conditioning while maintaining patient safety.
When assessment results for a Certified Cardiac Technician evaluation are inconclusive, the BEST practice is to:
Answer: Conduct additional assessment using alternative methods
Inconclusive results require additional assessment using alternative methods for triangulation.
What does MET stand for in exercise physiology?
Answer: Metabolic Equivalent of Task
MET stands for Metabolic Equivalent of Task and represents the ratio of metabolic rate during an activity to the resting metabolic rate, where 1 MET equals approximately 3.5 mL O2/kg/min.
Why is patient education important?
Answer: To ensure informed decisions and active participation in care
Patient education is crucial because it empowers individuals to make informed decisions about their health and actively participate in their care plan. When patients understand their condition, treatment options, and self-care strategies, they are more likely to adhere to recommendations and achieve better health outcomes. This collaborative approach fosters patient autonomy and improves overall treatment effectiveness.
Which electrolyte imbalance can potentiate digoxin toxicity and increase the risk of fatal arrhythmias?
Answer: Hypokalemia
Low potassium levels increase digoxin binding to Na+/K+-ATPase, greatly increasing its toxic effects and the risk of dangerous arrhythmias.
Which of the following is an ABSOLUTE contraindication to initiating cardiac rehabilitation exercise?
Answer: Unstable angina at rest
Unstable angina at rest is an absolute contraindication to exercise in cardiac rehabilitation because it indicates active myocardial ischemia that could worsen dangerously with exertion.
What is indicated by a prolonged QT interval?
Answer: Increased arrhythmia risk
A prolonged QT interval on an ECG indicates a delay in ventricular repolarization, which is the electrical recovery phase of the ventricles. This extended recovery period makes the heart more vulnerable to developing dangerous ventricular arrhythmias, such as Torsades de Pointes. Therefore, a prolonged QT interval is a significant marker for an increased risk of sudden cardiac death and requires careful monitoring.
In Certified Cardiac Technician practice, what is the FIRST step when a safety hazard is identified in the workplace?
Answer: Immediately secure the area and report the hazard
When a safety hazard is identified, the immediate priority is to secure the area to prevent injury and report the hazard through proper channels.
The 'a' wave seen in the jugular venous pulse (JVP) corresponds to which cardiac event?
Answer: Atrial contraction
The 'a' wave of the JVP reflects atrial contraction, which increases right atrial pressure and is transmitted back into the jugular veins just before ventricular systole.
During a stress test, the patient develops sustained ventricular tachycardia on the monitor. The CCT should immediately:
Answer: Stop the test, keep the patient calm, and activate the emergency response
Sustained VT is a life-threatening arrhythmia requiring immediate test termination and emergency response activation.
When documenting assessment findings in CCT practice, which approach is MOST appropriate?
Answer: Record objective findings, measurements, and observations factually
Assessment documentation must be objective, factual, and comprehensive.
In left bundle branch block (LBBB), which lead shows a broad monophasic R wave without a septal Q wave?
Answer: Lead V6
In LBBB, lead V6 (and lateral leads I, aVL) shows a broad, notched, monophasic R wave with absence of the normal septal Q wave.
According to OSHA Bloodborne Pathogen Standards, used ECG electrode gel-coated electrodes should be disposed of in:
Answer: A biohazard bag if they contacted intact skin during a routine ECG
Electrodes that contact skin and potentially bodily fluids should be treated as potentially infectious and disposed of in biohazard waste.
What is the normal duration of the PR interval?
Answer: 0.12 to 0.20 seconds
The PR interval on an ECG measures the time from the beginning of atrial depolarization (P wave) to the beginning of ventricular depolarization (QRS complex). A normal PR interval typically ranges from 0.12 to 0.20 seconds. This interval reflects the time it takes for the electrical impulse to travel from the atria, through the AV node, and into the ventricles.
A CCT accidentally sticks themselves with a needle used on a patient with unknown HIV status. The FIRST action should be:
Answer: Immediately wash the wound, report to supervisory staff, and follow exposure protocol
Immediate wound care, prompt reporting, and following facility exposure protocol are critical to minimize infection risk and begin prophylaxis within the optimal window.
During a Holter monitor hookup, the patient mentions they are claustrophobic. This information is relevant because:
Answer: Anxiety can produce artifact and affect heart rate variability results
Anxiety and claustrophobia can elevate heart rate and produce artifact, affecting the validity of the 24-hour recording.
