- Biological indicators containing resistant spore organisms (Correct answer)
Correct answer: Biological indicators containing resistant spore organisms
Biological indicators using highly resistant bacterial spores (e.g., Geobacillus stearothermophilus) provide the highest level of sterilization assurance because they directly challenge the sterilization process with living organisms.
Question 37: What is the recommended design flow in the SPD to minimize contamination risk?
- One-way flow from dirty to clean areas (Correct answer)
- Reverse flow from sterile to contaminated areas
- Random workflow based on staff availability
- Circular workflow with instruments passing through the same stations multiple times
Correct answer: One-way flow from dirty to clean areas
The recommended design flow in the SPD is a one-way, unidirectional flow from dirty (decontamination) to clean (assembly, sterilization, sterile storage) areas. This critical design principle prevents cross-contamination by ensuring that soiled instruments and personnel do not re-enter or pass through areas designated for clean or sterile items. This minimizes the risk of infection and maintains instrument sterility.
Question 38: Which type of personal protective equipment (PPE) is required in the decontamination area?
- Surgical scrubs and a hair cover
- Fluid-resistant gown, gloves, face mask, and eye protection (Correct answer)
