Question 1

Which of the following is an example of engineering control used to reduce needlestick injuries for biomedical technicians?

Accepted Answer

Using sharps containers with self-closing lids near the point of use

Answer

Sharps containers placed at the point of use are an engineering control that physically reduces the risk of needlestick injury.

Question 2

A biomedical technician finds a piece of equipment labeled with a biohazard symbol stored in an unlocked hallway cabinet. What is the correct response?

Accepted Answer

Transfer the equipment to a secured, designated biohazard storage area

Answer

Biohazardous equipment must be stored in secured, designated areas to prevent unauthorized access and potential exposure.

Question 3

During an electrical safety inspection, a technician measures ground wire resistance on a patient-care device. Acceptable ground resistance per NFPA 99 / AAMI standards is:

Accepted Answer

Less than 0.5 ohms

Answer

AAMI and NFPA 99 standards typically require ground wire resistance to be less than 0.5 ohms to ensure effective fault current pathway.

Question 4

Which organism is used as the biological indicator (BI) for monitoring ethylene oxide (EO) sterilization?

Accepted Answer

Bacillus atrophaeus

Answer

Bacillus atrophaeus spores are the standard biological indicator for EO sterilization because of their high resistance to the process.

Question 5

A biomedical technician is asked to service a portable X-ray unit. Which agency's regulations primarily govern radiation safety for this equipment in a US hospital?

Accepted Answer

NRC and state radiation control programs

Answer

The Nuclear Regulatory Commission (NRC) and individual state radiation control programs regulate radiation safety for medical X-ray equipment in US healthcare facilities.
