Which blood pressure reading obtained during an exercise stress test would be considered an absolute indication to stop the test?
Answer: Systolic BP dropping more than 10 mmHg from baseline despite increasing workload
A drop in systolic BP of more than 10 mmHg from baseline during exercise indicates hemodynamic instability and is an absolute stopping criterion.
When performing a 12-lead ECG on a patient in respiratory distress, electrode placement should be:
Answer: Completed quickly, documenting patient position if not supine
The ECG should be obtained promptly and any deviation from standard supine positioning must be documented for accurate interpretation.
A CCT notices that an ECG recording shows 60 Hz electrical interference. The MOST likely cause is:
Answer: Electrode contact with AC power interference from nearby equipment
60 Hz AC interference typically results from poor skin preparation or proximity to electrical equipment creating a ground loop.
Before performing a transthoracic echocardiogram, informed consent considerations require the CCT to:
Answer: Explain the procedure and ensure the ordering physician has obtained consent
The CCT explains the procedure to the patient; formal consent responsibility lies with the ordering physician, though patient understanding must be confirmed.
Proper hand hygiene before and after patient contact should take at minimum:
Answer: 15-20 seconds with soap and water or the equivalent with alcohol-based gel
CDC guidelines specify at least 15-20 seconds of hand washing or thorough alcohol-based sanitizer application to effectively reduce pathogen transmission.
A patient refuses to have ECG electrodes placed on their chest. The CCT's appropriate response is to:
Answer: Respect the refusal, document it, and notify the ordering physician
Competent patients have the right to refuse procedures; the CCT must document the refusal and communicate it to the care team.
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.
