✍️ Sample CET Questions & Answers
1. A CET discovers that echo images are being stored without encryption on a shared network drive accessible outside the hospital. The appropriate regulatory action is to:
Identified security vulnerabilities must be reported through proper internal channels—the Privacy or Security Officer—who will initiate the required risk assessment.
2. On echocardiography, which pattern of ventricular filling is most consistent with constrictive pericarditis?
Constrictive pericarditis characteristically shows >25% respiratory variation in mitral inflow E velocity due to ventricular interdependence.
3. Using the simplified Bernoulli equation, what is the pressure gradient across a valve if the peak velocity is 4 m/s?
The simplified Bernoulli equation is ΔP = 4V², so ΔP = 4 × (4)² = 4 × 16 = 64 mmHg.
4. Which Doppler pattern at the mitral valve is consistent with Grade I (impaired relaxation) diastolic dysfunction?
Grade I diastolic dysfunction (impaired relaxation) shows E/A ratio <1 and prolonged deceleration time due to slow myocardial relaxation.
5. Which publication bias phenomenon refers to studies with positive results being more likely to be published than those with null findings in echocardiographic research?
The 'file drawer problem' describes the tendency for null or negative studies to go unpublished, distorting the literature toward positive results.
6. What is a corrective action in Certified Echocardiography Technician quality systems?
Corrective actions address root causes of quality issues to prevent recurrence, going beyond temporary fixes to create lasting improvement.
