CCT - Certified Cardiographic Technician Exercise Stress Testing Questions and Answers

Question 1

A 78-year-old sedentary female is referred for a symptom-limited exercise stress test. Which of the following treadmill protocols is most appropriate for this patient?

Accepted Answer

Modified Bruce Protocol

Answer

The Modified Bruce Protocol starts at a lower workload (slower speed and less incline) and has smaller increments between stages compared to the Standard Bruce Protocol. This makes it more suitable for elderly, deconditioned, or post-myocardial infarction patients who may not tolerate the more demanding initial stages of the standard protocol.

Question 2

Which of the following findings is considered an absolute indication to terminate an exercise stress test immediately?

Accepted Answer

Patient request to stop

Answer

According to AHA/ACC guidelines, a patient's request to stop is an absolute indication for terminating the test. While arrhythmias, ST depression, and hypertension are significant and may lead to test termination (often as relative indications), the patient's explicit desire to stop must be honored immediately.

Question 3

A 60-year-old male is scheduled for a maximal exercise stress test. Using the most common standard formula, what is his age-predicted maximum heart rate (MHR)?

Accepted Answer

160 bpm

Answer

The most widely used and simplest formula to estimate maximum heart rate is 220 minus the patient's age. For a 60-year-old patient, the calculation is 220 - 60 = 160 bpm.

Question 4

A CCT is preparing a patient for a treadmill stress test. To ensure a high-quality ECG tracing with minimal artifact, what is the most critical preparatory step?

Accepted Answer

Abrading the skin at electrode sites

Answer

Proper skin preparation, which includes cleaning and abrading the stratum corneum, is crucial for reducing skin impedance. Lower impedance allows for a better electrical signal to reach the electrode, significantly minimizing motion and other artifacts that are common during exercise.

Question 5

During the recovery phase of an exercise stress test, continuous monitoring of the patient's ECG and vital signs is essential. For how long should this monitoring typically continue?

Accepted Answer

For at least 6-8 minutes, or until ECG changes and symptoms resolve

Answer

The post-exercise recovery period is diagnostically important, as some ischemic changes or arrhythmias may only appear after the exercise has stopped. Standard procedure is to monitor the patient for a minimum of 6-8 minutes, and potentially longer if ECG abnormalities or patient symptoms persist or worsen.
