When performing incoming inspection on a new medical device, which document should be verified first?
Answer: Purchase order and packing slip
The purchase order and packing slip must be verified first to confirm the correct item was received and is undamaged before proceeding with inspection.
A biomedical technician installs a new infusion pump and notices the alarm system does not respond during self-test. What is the most appropriate next action?
Answer: Label the device as out-of-service and notify clinical staff
A non-functional alarm on a safety-critical device like an infusion pump means it must be taken out of service immediately until repaired and verified.
Which grounding resistance value is generally acceptable for a hospital-grade receptacle outlet?
Answer: Less than 0.1 ohm
NFPA 99 requires that hospital-grade receptacles have a grounding resistance of less than 0.1 ohm to ensure safe electrical grounding.
What is the primary purpose of a preventive maintenance (PM) schedule for biomedical equipment?
Answer: To ensure equipment performs safely and reliably between corrective repairs
Preventive maintenance ensures equipment continues to operate safely and reliably by identifying and correcting potential issues before they cause failure.
During installation of a patient monitoring system, the technician discovers the network port assignment conflicts with an existing device on the LAN. Who should be contacted to resolve this?
Answer: The hospital's IT/biomedical informatics department
Network IP address and port conflicts must be resolved by the hospital IT or biomedical informatics team who manage the clinical network infrastructure.
A ventilator's flow sensor reads consistently 15% higher than the reference standard during calibration. This is an example of:
Answer: Systematic bias (offset error)
A consistent, predictable deviation in one direction from the true value is called systematic bias or offset error, which can often be corrected through calibration adjustment.
Which test is used to verify that a defibrillator delivers the correct energy output?
Answer: Energy output test using a defibrillator analyzer
A defibrillator analyzer measures the actual energy delivered into a known load to confirm that the device outputs the correct joule setting.
