DOMAIN 1: REGULATIONS & SAFETY (Questions 1–15)
Question 1
Which organization publishes the comprehensive standards for sterilization and
infection control in healthcare facilities that central service technicians must
follow?
A) FDA (Food and Drug Administration)
B) AAMI (Association for the Advancement of Medical Instrumentation)
C) WHO (World Health Organization)
D) EPA (Environmental Protection Agency)
,Rationale: AAMI publishes the comprehensive standards for sterilization,
infection control, and medical device processing that central service technicians
must follow. While the FDA regulates medical devices, OSHA oversees workplace
safety, and CDC provides infection control guidelines, AAMI is the primary
standards-developing organization for sterile processing practices.
Question 2
A central service technician notices a coworker repeatedly failing to wear proper
PPE during decontamination. What is the technician's most appropriate first
action?
A) Ignore the behavior to avoid conflict
B) Report the concern to the supervisor immediately
C) Confront the coworker aggressively
D) Document the behavior in a personal log only
Rationale: Patient and staff safety is paramount in central service. The technician
has an ethical and professional obligation to report safety violations. Reporting to
the supervisor ensures proper corrective action while maintaining professional
boundaries. Confrontation or ignoring the issue could compromise safety.
Question 3
Under HIPAA regulations, which of the following actions by a central service
technician would constitute a violation?
A) Discussing a surgical instrument's sterilization status with a surgeon
B) Sharing a patient's name and procedure type with an unauthorized
individual
C) Documenting instrument counts in the tracking system
D) Reporting a safety hazard to the supervisor
Rationale: HIPAA protects patient health information (PHI). Sharing a patient's
name, procedure, or any identifying information with unauthorized individuals is a
violation. Discussing instrument status with clinical staff, documenting counts, and
reporting safety hazards are all appropriate professional activities.
,Question 4
What is the primary purpose of the "event-related sterility" concept?
A) To ensure all packages are dated with expiration dates
B) To indicate that sterility depends on package integrity and storage
conditions, not a fixed time
C) To require resterilization of all packages after 30 days
D) To eliminate the need for biological monitoring
Rationale: Event-related sterility means that a sterile package remains sterile until
an event compromises its integrity. This concept shifted practice away from fixed
expiration dates toward package inspection for damage, moisture, or contamination
before each use.
Question 5
Which federal agency is responsible for enforcing workplace safety standards,
including those related to chemical exposure in central service departments?
A) CDC (Centers for Disease Control and Prevention)
B) FDA (Food and Drug Administration)
C) OSHA (Occupational Safety and Health Administration)
D) AAMI (Association for the Advancement of Medical Instrumentation)
Rationale: OSHA enforces workplace safety standards, including chemical
exposure limits, bloodborne pathogen standards, and PPE requirements. CDC
provides infection control guidelines, FDA regulates medical devices, and AAMI
develops sterilization standards.
Question 6
A central service technician is asked to process a loaner instrument set that arrived
without manufacturer's instructions for use (IFUs). What should the technician do?
A) Process the set using standard hospital protocol
B) Contact the loaner company to obtain the IFUs before processing
C) Process the set but document the missing IFUs
D) Refuse to process the set entirely
, Rationale: IFUs are essential for proper processing. Processing without IFUs
could damage instruments or fail to achieve sterilization. The technician must
obtain the IFUs before proceeding.
Question 7
What does the acronym "RACE" stand for in healthcare fire safety?
A) Remove, Alarm, Contain, Extinguish
B) Rescue, Alarm, Contain, Extinguish
C) Rescue, Activate, Call, Evacuate
D) Remove, Assess, Contain, Exit
Rationale: RACE is the standard fire safety response protocol: Rescue anyone in
immediate danger, Alarm (activate the fire alarm), Contain the fire (close
doors), Extinguish (use fire extinguisher if safe).
Question 8
Which of the following is an example of a sentinel event that must be reported?
A) A minor paperwork error in instrument tracking
B) A surgical procedure performed with a contaminated instrument
C) A delay in instrument delivery to the OR
D) An employee arriving late to work
Rationale: A sentinel event is an unexpected occurrence involving death or serious
physical or psychological injury. A contaminated instrument used in surgery could
cause serious patient harm and must be reported through proper channels.
Question 9
What is the proper sequence for donning (putting on) PPE in the decontamination
area?
A) Gown, gloves, mask, eye protection
B) Mask, gown, gloves, eye protection
C) Gown, mask, eye protection, gloves
D) Gloves, gown, mask, eye protection
