MDRAO EXAMINATION (MEDICAL DEVICE
REPROCESSING & ADMINISTRATIVE OVERSIGHT
EXAM) 2026-27 LATEST VERSION
Introduction
The MDRAO Examination evaluates advanced knowledge and administrative competence in medical device
reprocessing, sterilization systems, infection prevention, and regulatory oversight within healthcare facilities. This
exam is critical for professionals responsible for ensuring that reusable medical equipment is safely cleaned,
disinfected, sterilized, stored, and documented according to international standards.
Candidates are expected to demonstrate:
• Deep understanding of decontamination workflows
• Knowledge of sterilization technologies (steam, ethylene oxide, low-temperature systems)
• Competence in infection prevention & control
• Ability to manage quality assurance programs
• Familiarity with regulatory compliance and audit readiness
• Skills in risk management and incident response
This exam reflects real-world challenges in Central Sterile Services Departments (CSSD) and healthcare
administration.
Exam Structure
The exam consists of 100 complex MCQs, divided into:
1. Decontamination & Cleaning Processes (15 questions)
2. Disinfection & Sterilization Methods (20 questions)
3. Instrumentation & Equipment Handling (10 questions)
4. Infection Prevention & Control (15 questions)
5. Quality Assurance & Monitoring (10 questions)
6. Regulatory Compliance & Documentation (10 questions)
7. Occupational Safety & Risk Management (10 questions)
8. Leadership & Administration (10 questions)
,2
Exam Format
• 100 scenario-based multiple-choice questions (A–D)
• One correct answer per question
• Each includes detailed rationale
• Focus on application, not memorization
1.
A surgical instrument is visibly contaminated with blood after
use. What is the first step in reprocessing?
A. Sterilization
B. High-level disinfection
C. Cleaning (decontamination)
D. Packaging
Answer: C
Rationale:
Cleaning (decontamination) is always the first and most critical
step because organic material (blood, tissue) can block
disinfectants and sterilizing agents, making subsequent
processes ineffective.
• A is incorrect: Sterilization cannot work effectively on dirty
instruments.
,3
• B is incorrect: Disinfection is ineffective if organic matter is
present.
• D is incorrect: Packaging occurs only after cleaning and
drying.
2.
Which factor most affects the effectiveness of cleaning?
A. Color of instrument
B. Organic material presence
C. Storage method
D. Packaging type
Answer: B
Rationale:
Organic material (blood, proteins) inhibits detergents and
disinfectants, making cleaning ineffective if not removed.
• A is incorrect: Color has no impact on cleaning.
• C is incorrect: Storage matters later, not during cleaning.
• D is incorrect: Packaging is unrelated to cleaning
effectiveness.
3.
, 4
Which sterilization method is best for heat-sensitive devices?
A. Steam sterilization
B. Dry heat
C. Ethylene oxide (EtO)
D. Boiling
Answer: C
Rationale:
Ethylene oxide is a low-temperature sterilization method, ideal
for heat- and moisture-sensitive devices.
• A is incorrect: Steam uses high temperature and
moisture—damages sensitive devices.
• B is incorrect: Dry heat also uses high temperatures.
• D is incorrect: Boiling does not achieve sterilization (does
not kill spores).
4.
What is the minimum requirement before sterilization?
A. Drying
B. Cleaning
C. Packaging
D. Storage
Answer: B
