BTC Clinical Procedures & Protocols 2

Question 1

When performing a point-of-care glucose test, the first drop of blood from a finger stick should be:

Accepted Answer

Wiped away before collecting the sample

Answer

The first drop is wiped away because it may be contaminated with tissue fluid, which can dilute the sample and affect accuracy.

Question 2

A biomedical technician is asked to verify a ventilator's tidal volume delivery. Which tool is most appropriate?

Accepted Answer

Spirometer calibration syringe

Answer

A calibration syringe of known volume is used to verify that the ventilator delivers the set tidal volume accurately.

Question 3

According to standard protocol, how often should an infusion pump's occlusion alarm be tested during preventive maintenance?

Accepted Answer

Annually at minimum per manufacturer schedule

Answer

Occlusion alarms must be functionally tested at least annually as part of scheduled preventive maintenance per manufacturer requirements.

Question 4

Which sterilization method is most appropriate for heat-sensitive endoscopic equipment?

Accepted Answer

Ethylene oxide (EtO) gas sterilization

Answer

EtO gas sterilization is used for heat-sensitive devices because it operates at low temperatures while achieving sterilization.

Question 5

During defibrillator testing, which parameter confirms that the device delivered the intended energy to the patient load?

Accepted Answer

Delivered energy measured at the output

Answer

Delivered energy measured at the output (using a defibrillator analyzer) confirms actual energy transfer to the patient load, not just stored charge.
