Processing Association (HSPA) CRCST | 2026/2027
Edition Comprehensive Examination
Introduction
This comprehensive examination document is specifically designed for
candidates preparing for the IAHCSMM (HSPA) CRCST Certification
Examination for the 2026/2027 cycle. The content is structured around the
official HSPA CRCST curriculum blueprint, encompassing all critical domains:
Decontamination and Disinfection, Preparation Assembly and Packaging,
Sterilization Methodologies and Monitoring, Sterile Storage Distribution and
Inventory, and Patient Care Equipment Instrumentation and Infection
Prevention. Each of the 85 questions has been expertly verified to reflect the
most current ANSI/AAMI standards, CDC guidelines, OSHA regulations, and
AORN recommended practices as applicable for 2026/2027. This document
provides 100% verified correct answers with detailed rationales, designed to
ensure accurate self-evaluation and pass-level readiness for the actual
examination.

,Question 1
What is the correct order of the sterilization processing workflow in a Central
Service department?
A) Sterilization, Assembly, Decontamination, Storage
B) Decontamination, Assembly, Sterilization, Storage
C) Assembly, Decontamination, Sterilization, Storage
D) Decontamination, Sterilization, Assembly, Storage
Rationale: The standard workflow follows a one-way flow from dirty to clean:
Decontamination (initial cleaning/disinfection), Assembly and Packaging,
Sterilization, and finally Sterile Storage and Distribution. This prevents cross-
contamination by ensuring that soiled and clean items never travel the same
path.
Question 2
Which of the following is considered a high-level disinfectant?
A) Isopropyl alcohol (70%)
B) Quaternary ammonium compounds
C) Glutaraldehyde
D) Household bleach (1:100 dilution)
Rationale: Glutaraldehyde (e.g., Cidex) is classified as a high-level
disinfectant/chemical sterilant when used at the appropriate concentration
and contact time. Alcohol is an intermediate-level disinfectant, quaternary
ammonium compounds are low-level, and dilute bleach is an intermediate-
level disinfectant.
Question 3
What is the minimum recommended temperature for the mechanical wash
cycle in a washer-disinfector?
A) 140°F (60°C)
B) 150°F (66°C)
, C) 180°F (82°C)
D) 212°F (100°C)
Rationale: AAMI standards recommend a minimum thermal disinfection
temperature of 150°F (66°C) for the mechanical wash cycle, maintained for a
minimum of 30 seconds to achieve thermal disinfection. This temperature is
sufficient to kill most vegetative microorganisms.
Question 4
Personal protective equipment (PPE) in the decontamination area must
include all of the following EXCEPT:
A) Fluid-resistant gown
B) Sterile surgical gloves
C) Face shield or goggles
D) Heavy-duty utility gloves
Rationale: PPE in decontamination includes heavy-duty utility gloves, not
sterile surgical gloves. Utility gloves provide greater puncture and chemical
resistance. Other required PPE includes a fluid-resistant gown, face shield or
goggles, shoe covers, and appropriate respiratory protection when indicated.
Question 5
According to the Spaulding Classification, surgical instruments that enter
sterile tissue or the vascular system are classified as:
A) Non-critical items
B) Semicritical items
C) Critical items
D) Environmental surfaces
Rationale: Critical items under the Spaulding Classification are those that
enter sterile tissue or the vascular system (e.g., surgical instruments,
implants). These require sterilization. Non-critical items contact intact skin
only, and semicritical items contact mucous membranes and require high-
level disinfection.
