1. A biomedical equipment technician is most responsible for which
primary function?
A. Diagnosing patient diseases
B. Performing preventive and corrective maintenance on medical
equipment
C. Prescribing medical devices
D. Conducting surgical procedures
Answer: B
Rationale: A CBET focuses on ensuring medical devices are safe,
functional, and properly maintained through preventive and
corrective maintenance, not clinical diagnosis or treatment.
2. Which electrical unit represents current?
A. Volt
, B. Watt
C. Ampere
D. Ohm
Answer: C
Rationale: Current is measured in amperes (A), which represents
the flow of electric charge.
3. According to Ohm’s Law, voltage equals:
A. Current × Resistance
B. Power ÷ Time
C. Resistance ÷ Current
D. Current ÷ Resistance
Answer: A
Rationale: Ohm’s Law defines voltage (V) as current (I) multiplied
by resistance (R): V = IR.
4. What is the primary purpose of equipment preventive
maintenance?
A. Increase device complexity
B. Reduce device lifespan
C. Prevent unexpected equipment failure
, D. Replace clinical staff
Answer: C
Rationale: Preventive maintenance reduces breakdowns and
ensures equipment reliability and patient safety.
5. Which device delivers controlled electrical energy to a patient’s
heart during cardiac arrest?
A. ECG monitor
B. Defibrillator
C. Infusion pump
D. Pulse oximeter
Answer: B
Rationale: A defibrillator delivers a controlled shock to restore
normal heart rhythm during life-threatening arrhythmias.
6. What does an ECG monitor measure?
A. Blood oxygen level
B. Heart electrical activity
C. Blood glucose
D. Lung capacity
Answer: B
, Rationale: ECG devices measure the electrical signals produced
by the heart over time.
7. Which organization regulates medical devices in the United
States?
A. WHO
B. FDA
C. CDC
D. OSHA
Answer: B
Rationale: The FDA (Food and Drug Administration) regulates
the safety and effectiveness of medical devices.
8. What is leakage current?
A. Desired current in a circuit
B. Current flowing through grounding wire only
C. Unintended current flowing through an undesired path
D. Battery charging current
Answer: C
Rationale: Leakage current is unwanted electrical current that
may pose a shock hazard to patients or staff.
