CBET FC 2024/25 Test Questions and Answers1. The recommended enclosure risk current limit portable equipment that is "likely to contact
patient", under normal conditions, as specified by the ANSI/AAMI Safe Current Limits for
Electromedical Apparatus standard (ANSI/AAMI ES1) is Correct Ans-100 microamperes
(Normal condition - 100mA, Single fault condition - 300 mA)
2. According to NFPA 99, when a hospital buys equipment, the following information must be
included with the purchase order, Correct Ans-listing or certification requirements,
identification of unusual conditions, such as high humidity, a request for operator and service
manuals, except a request for appropriate Material Safety Data Sheets
3. When servicing equipment used to deliver oxygen, oil and grease should not be used
because Correct Ans-oil and grease may cause a fire hazard in an oxygen-enriched
atmosphere
4. The human body's "cannot let go" reaction to 60 hertz current begins at about ...mA
Correct Ans-10 milliamperes
5. A current intensity of 5 milliamperes is generally accepted as the Correct Ans-maximum
harmless current intensity
5. The minimum body-surface-contact 60 hertz current that will induce ventricular fibrillation
in an adult human is about Correct Ans-100 milliamperes

6. The two major components of leakage current are Correct Ans-capacitive and resistive
20. A medical oxygen gas cylinder is color coded Correct Ans-green with silver rim
21. NFPA 99 requires testing of equipment before being put into service, after repair or
modification and at intervals determined by the equipment's location. Unless documentation
justifies otherwise, intervals should not exceed Correct Ans-general care areas 12 months,
critical care areas 6 months, wet locations 6 months
22. In NFPA 99, standard for health care facilities, the maximum acceptable testing interval for
testing receptacles in critical care areas is Correct Ans-6 months
General care areas: 12 months
Critical care areas: 6 months
Wet locations: 12 months
1. Personnel Monitoring devices for monitoring radiation exposure include Correct Ans-
Film badge,
Optically stimulated luminescence dosimeter,
Pocket ionization chamber

conductor of an isolated power system in an anesthetizing location to exceed ... ohms
Correct Ans-200,000 ohms

3. The set of wires in compliance with the Nation Electrical Code (ANSI/NFPA 70) standard
color code for electrical power wiring distribution is: Correct Ans-Black/red (hot),
white/natural gray (neutral), green/green with one or more yellow stripes (ground)
4. The International Electrotechnical Commission (IEC) color code for an electrical power cord
in order of hot, neutral and ground is Correct Ans-brown, blue and green
5. The system providing the most protection against leakage current hazards in an
electrocardiograph is Correct Ans-driven right leg ECG amplifier system
6. A Line Isolation Monitor (LIM) is a device that continuously monitors the Correct Ans-
impedance of isolated power lines to ground
7. NFPA 99, Standard for Health Care Facilities, requires a LIM alarm trip when total hazard
current from either isolated conductor to ground reaches a threshold value of Correct Ans-
5.0 mA
8. According to NFPA 99, the line isolation monitor must have Correct Ans-a green lamp
that remains lighted when the electrical system is adequately isolated from ground,
a red lamp and audible warning signal that activates when the total hazard current reaches
threshold value,
an ammeter that indicates the total hazard current of the electrical system
