CER practice test
Practice by official exam domains
CER preparation depends on process order and detail. Practice point-of-use care, leak testing, manual cleaning, high-level disinfection, drying, storage, documentation, and human factors as connected workflow decisions.
Microbiology and Infection Control
Pathogenic and non-pathogenic microorganisms, biofilm formation, environmental cleaning, Spaulding classification, PPE and hygiene.
Endoscope Purpose, Design and Structure
Benefits of endoscopic procedures, endoscope categories, anatomy and components, processing challenges and accessories.
Work Area Design
Workflow design, environmental requirements, cross-contamination prevention, PPE location and decontamination area requirements.
Endoscope Processing Steps
Point-of-use care, transportation, visual inspection, leak testing, manual cleaning, rinsing, HLD, AERs, drying and sterilization.
Endoscope Handling, Transport and Storage
Proper handling techniques, storage requirements, storage systems, hang time, risk assessment and transportation procedures.
Endoscope Tracking, Repair and System Maintenance
Processing documentation, routine equipment checks, repair requirements, tracking systems and common repair issues.
Human Factors That Impact Endoscope Systems
Human impact on processing systems, common errors and omissions, staffing, communication, audits, education and training.
Sample CER questions
These examples show the style of practice: choose an answer, then study the rationale.
Question 1
When should endoscope pre-cleaning begin?
Why: Prompt point-of-use care helps prevent drying soil and biofilm formation inside channels.
Question 2
Why is leak testing performed before manual cleaning?
Why: A failed leak test can indicate damage that may allow fluid invasion and require removal from service.
Question 3
What should endoscope documentation support?
Why: Tracking links the scope, processing cycle, staff, and patient encounter for quality and recall needs.
Frequently asked questions
What topics are on the CER exam?
CER practice includes microbiology, endoscope design, work area design, processing steps, handling, storage, tracking, repair, system maintenance, and human factors.
Is CER only about high-level disinfection?
No. High-level disinfection is important, but the exam also tests the full workflow from point-of-use care through storage and documentation.
Can I practice CER questions for free?
Yes. Sterile Processing Prep lets you start with free CER practice questions and upgrade when you need unlimited practice and mock exams.
