COMPLETE STUDY GUIDE
QUESTIONS WITH 100% VERIFIED
ANSWERS (LATEST UPDATE 2026 |
This is Sterile Processing Final Exam, typically the Certified Registered Central Service
Technician (CRCST) exam, is a 3-hour computer-based test consisting of 150 multiple-
choice questions. Of these, 125 are scored and 25 are unscored "pre-test" questions used
for statistical evaluation. To pass, candidates generally need a minimum score of 70%.
Core Exam Domains
The exam is designed to verify a technician's competence in several key areas. The bulk of
the content (over 60%) focuses on cleaning, decontamination, and sterilization processes.
Cleaning, Decontamination & Disinfection (approx. 21%): Focuses on removing
bioburden, preventing soil from drying on instruments, and the use of chemical disinfectants.
Preparation & Packaging (approx. 20%): Covers instrument inspection for cleanliness and
functionality, lubrication (based on Instructions for Use or IFU), and assembly using count
sheets.
Sterilization Process (approx. 26%): Includes knowledge of steam sterilization (the most
common method), low-temperature sterilization, and the use of chemical indicators or
integrators.
Patient Care Equipment & Safety (approx. 10%): Handling of medical equipment and
understanding basic anatomy, physiology, and medical terminology.
Sterile Storage & Inventory Management (approx. 11%): Maintaining the integrity of sterile
items and managing supply distribution.
1
, Documentation & Quality Assurance (approx. 12%): Record maintenance, regulatory
compliance, and testing tools like insulation testers.
Key Study Topics
Bioburden: The number of microorganisms on a contaminated object; pre-cleaning at the
point of use is critical to prevent it from drying.
Moisture Saturation: Crucial for microbial cell wall collapse during heat transfer in
sterilization.
Packaging Methods: Differences between peel packs, wraps, and rigid containers, as well as
wrapping techniques like the envelope or square fold.
Instrument Care: Identification of damaged tools (dull or misaligned) and proper placement
to facilitate sterilization.
Preparation Tips
Resource Manual: The HSPA 9th edition manual is considered the primary source for exam
content.
Eligibility: Full certification requires 400 hours of hands-on experience, verified by a
supervisor.
Study Strategy: Focus heavily on Chapters 7–9, 12–15, 17, 18, and 22 of the manual, which
cover the most heavily weighted sections of the test.
