✍️ Sample CET Questions & Answers
1. 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.
2. 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.
3. 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.
4. 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.
5. Which frequency range is typically used for adult transthoracic echocardiography?
For adult transthoracic echocardiography, a frequency range of 2-5 MHz is typically used. Lower frequencies offer greater penetration depth, which is necessary to visualize the heart through the chest wall in adults. While higher frequencies provide better resolution, they have limited penetration, making the 2-5 MHz range optimal for balancing depth and image quality in adult studies.
6. Why is documentation important in CET risk management?
Documentation in risk management creates accountability, supports decision-making, and demonstrates professional due diligence.
