- Which of the following is the primary purpose of preventative
maintenance on medical equipment?
a) Increase patient discomfort
b) Reduce equipment lifespan
c) Ensure equipment reliability and safety
d) Increase repair costs
Rationale: Preventative maintenance ensures that equipment functions
correctly, reduces breakdowns, and maintains patient safety.
- Which device measures electrical activity of the heart?
a) Spirometer 1 / 4
b) Electrocardiograph (ECG/EKG)
c) Pulse oximeter
d) Defibrillator
Rationale: ECGs measure the heart's electrical activity to assess rhythm
and detect abnormalities.
- In a hospital setting, which standard ensures electrical safety of
medical devices?
a) ISO 9001
b) IEC 60601
c) ASTM F963
d) NFPA 101
Rationale: IEC 60601 is the international standard for the safety and
performance of medical electrical equipment.
- What is the primary function of a defibrillator?
a) Measure blood pressure
b) Monitor oxygen saturation
c) Deliver a controlled electrical shock to restore heart rhythm
d) Assess respiratory rate
Rationale: Defibrillators are used in emergencies to correct life-threatening
arrhythmias.
- Which type of biomedical equipment uses a transducer to detect
ultrasound waves? 2 / 4
a) X-ray machine
b) MRI
c) Ultrasound machine
d) Ventilator
Rationale: Ultrasound machines convert electrical energy into sound waves
and back to create images.
- Which law regulates safe disposal of biomedical waste in hospitals?
a) FDA Act
b) OSHA Bloodborne Pathogens Standard
c) RCRA (Resource Conservation and Recovery Act)
d) HIPAA
Rationale: RCRA governs the proper disposal of hazardous and biomedical
waste to protect health and environment.
- What is the correct unit for measuring electrical resistance?
a) Volt
b) Ampere
c) Ohm
d) Watt
Rationale: Resistance is measured in Ohms (Ω), indicating opposition to
current flow.
- Which type of battery is commonly used in portable medical devices
due to high energy density? 3 / 4
a) Lead-acid
b) Nickel-cadmium
c) Lithium-ion
d) Zinc-carbon
Rationale: Lithium-ion batteries are lightweight, rechargeable, and have
high energy density suitable for medical devices.
- Which piece of equipment is essential for monitoring a patient’s
respiratory status?
a) Defibrillator
b) Ventilator and capnograph
c) ECG machine
d) Infusion pump
Rationale: Ventilators support breathing, and capnographs monitor CO₂
levels, indicating respiratory function.
- Which technique is most effective for sterilizing heat-sensitive
medical equipment?
a) Autoclaving
b) Dry heat sterilization
c) Ethylene oxide (EtO) gas sterilization
d) Boiling water
Rationale: EtO gas is used for sterilizing equipment that cannot withstand
high temperatures.
