✍️ Sample BTC Questions & Answers
1. When an IV infusion pump alarms 'Occlusion Downstream' during emergency drug delivery, the technician should:
A downstream occlusion alarm indicates a blockage between the pump and patient; inspecting the IV line for kinks or closed clamps resolves the most common causes.
2. A dialysis machine's conductivity alarm activates repeatedly during treatment despite correct concentrate ratios. What should be investigated?
Consistent conductivity alarms with correct concentrates often indicate water quality problems — high mineral content or failing deionization — that shift the dialysate conductivity.
3. In a biomedical equipment management program, 'acceptance testing' is performed to:
Acceptance testing is conducted on newly received devices to confirm they meet the manufacturer's performance specifications and are safe for patient use.
4. Which professional standard requires biomedical technicians to maintain accurate and complete service records for all medical equipment?
The Joint Commission requires comprehensive equipment service records as part of hospital accreditation and patient safety standards.
5. A hospital bed's scale function reads incorrectly. The technician zeroes the scale with no patient, but readings drift over time. What is the likely fault?
Load cell drift or a poor connection causes the signal to change over time even under a constant load, producing inaccurate weight readings.
6. Which type of isolation transformer is used in electrically sensitive patient areas (e.g., cardiac catheterization labs) to reduce shock hazard?
A line isolation transformer (LIM) with a line isolation monitor limits ground fault current in wet/electrically sensitive locations, reducing microshock risk.
