  1. A biomedical technician is troubleshooting an infusion pump that delivers inconsistent flow rates. Which component is MOST likely responsible?

    Answer: Peristaltic pump mechanism

    The peristaltic pump mechanism directly controls fluid delivery, and wear or misalignment causes inconsistent flow rates.

  2. According to NFPA 99, the maximum allowable ground resistance for a receptacle in a patient care area is:

    Answer: 0.1 ohms

    NFPA 99 requires receptacle ground resistance to not exceed 0.1 ohms in patient care areas to ensure electrical safety.

  3. Which type of fire extinguisher is appropriate for electrical equipment fires in a biomedical equipment area?

    Answer: Class C (CO2 or dry chemical)

    Class C extinguishers use non-conductive agents like CO2 or dry chemical, making them safe for energized electrical equipment fires.

  4. A patient monitor displays an artifact that disappears when the patient's lead wires are disconnected. This MOST likely indicates:

    Answer: EMI from external sources coupling through the leads

    When artifact disappears upon lead disconnection, the leads are acting as antennas picking up electromagnetic interference from external sources.

  5. The term 'microshock' refers to hazardous current delivered:

    Answer: Directly to the heart via an intracardiac catheter at levels as low as 10 µA

    Microshock occurs when current bypasses skin resistance and reaches the heart directly, where as little as 10 µA can induce ventricular fibrillation.

  6. During preventive maintenance on a ventilator, the BIOMED finds the exhalation valve is slow to close. The MOST immediate patient safety concern is:

    Answer: Inadequate tidal volume delivery due to gas leakage

    A slow-closing exhalation valve allows delivered gas to escape before full tidal volume is delivered to the patient's lungs.

  7. Which standard specifically governs the safety requirements for medical electrical equipment in the United States?

    Answer: ANSI/AAMI ES60601-1

    ANSI/AAMI ES60601-1 is the US adoption of IEC 60601-1 and governs general safety requirements for medical electrical equipment.
