✍️ Sample CET Questions & Answers

1. When should an EKG technician perform a daily equipment check on the machine?
✓ At the start of each shift before the first patient

A pre-shift equipment check ensures the machine is functional, charged, stocked with paper, and producing an accurate calibration pulse before patient use.

2. What is the primary purpose of standardized procedures in Cardiac Anatomy?
✓ To ensure consistency, safety, and quality across all practitioners

Standardized procedures ensure that all practitioners deliver consistent, safe, and high-quality outcomes.

3. Which of the following is the MOST common cause of 60 Hz (AC) interference on an EKG?
✓ Poor electrode contact or nearby electrical equipment

AC interference (60 Hz hum) typically results from nearby electrical equipment or degraded electrode-skin contact.

4. A patient has a heart rate of 150 bpm with narrow QRS complexes and no visible P waves. Which rhythm is most likely?
✓ Junctional tachycardia

Junctional tachycardia presents with a rate of 100–180 bpm, narrow QRS, and absent or retrograde P waves.

5. An EKG technician notices the patient is diaphoretic and unresponsive mid-procedure. The FIRST action should be:
✓ Call for immediate clinical assistance and activate emergency response

An unresponsive, diaphoretic patient is a medical emergency requiring immediate activation of emergency response before any other action.

6. Which factor is contributing to the growing demand for Certified EKG Technicians?
✓ Aging population and higher incidence of heart disease

The demand for Certified EKG Technicians is significantly influenced by demographic trends. As the population ages, there's a higher incidence of chronic conditions, particularly heart disease. This increases the need for diagnostic tests like EKGs, driving the demand for skilled technicians to perform these vital procedures.
