CCT Patient Care & Clinical Safety Standards 3

Question 1

Which blood pressure reading obtained during an exercise stress test would be considered an absolute indication to stop the test?

Accepted Answer

Systolic BP dropping more than 10 mmHg from baseline despite increasing workload

Answer

A drop in systolic BP of more than 10 mmHg from baseline during exercise indicates hemodynamic instability and is an absolute stopping criterion.

Question 2

When performing a 12-lead ECG on a patient in respiratory distress, electrode placement should be:

Accepted Answer

Completed quickly, documenting patient position if not supine

Answer

The ECG should be obtained promptly and any deviation from standard supine positioning must be documented for accurate interpretation.

Question 3

A CCT notices that an ECG recording shows 60 Hz electrical interference. The MOST likely cause is:

Accepted Answer

Electrode contact with AC power interference from nearby equipment

Answer

60 Hz AC interference typically results from poor skin preparation or proximity to electrical equipment creating a ground loop.

Question 4

Before performing a transthoracic echocardiogram, informed consent considerations require the CCT to:

Accepted Answer

Explain the procedure and ensure the ordering physician has obtained consent

Answer

The CCT explains the procedure to the patient; formal consent responsibility lies with the ordering physician, though patient understanding must be confirmed.

Question 5

Proper hand hygiene before and after patient contact should take at minimum:

Accepted Answer

15-20 seconds with soap and water or the equivalent with alcohol-based gel

Answer

CDC guidelines specify at least 15-20 seconds of hand washing or thorough alcohol-based sanitizer application to effectively reduce pathogen transmission.
