Sterilization and Disinfection (Questions 1-24)
1. What is the primary function of a Process Challenge Device ($\text{PCD}$) used during routine process monitoring?
A. To confirm the external chemical indicator changes color.
B. To physically test the ability of steam to penetrate a specific load configuration.
C. To measure the total output of ethylene oxide gas.
D. To record the total time the sterilizer spends in the exhaust phase.
Correct Answer: B. To physically test the ability of steam to penetrate a specific load configuration.
Rationale: A $\text{PCD}$ (often containing a $\text{BI}$ or integrator) is used to challenge the sterilizer's ability to
reach the critical zone within the most difficult location of a typical load.
2. A gravity steam sterilizer cycle fails the Bowie-Dick test. This indicates a deficiency in:
A. Spore viability.
B. Dry heat retention.
C. Air removal efficiency.
D. Post-cycle aeration time.
Correct Answer: C. Air removal efficiency.
Rationale: The Bowie-Dick test specifically assesses the sterilizer's ability to remove air and allow uniform penetration of
saturated steam.
, 3. Which low-temperature sterilization method leaves behind non-toxic byproducts of water and oxygen?
A. Ethylene Oxide ($\text{EO}$).
B. Hydrogen Peroxide Gas Plasma ($\text{H P P}$).
C. Ozone Sterilization.
D. Peracetic Acid ($\text{PAA}$) Immersion.
Correct Answer: B. Hydrogen Peroxide Gas Plasma ($\text{H P P}$).
Rationale: The $\text{H P P}$ process breaks down hydrogen peroxide into water vapor and oxygen gas, resulting in no
toxic residuals requiring aeration.
4. What is the primary purpose of the aeration phase in an $\text{EO}$ cycle?
A. To ensure the load cools before packaging.
B. To reduce residual toxic ethylene oxide gas.
C. To provide the necessary humidity for spore kill.
D. To dry porous packaging materials.
Correct Answer: B. To reduce residual toxic ethylene oxide gas.
Rationale: Aeration is a mandatory post-sterilization step to allow absorbed $\text{EO}$ gas to desorb from materials,
reaching safe clinical limits.
5. Which sterilization modality is generally contraindicated for processing large quantities of cotton textiles?
A. Dry Heat.
B. Low-Temperature Steam Formaldehyde ($\text{LTSF}$).
C. Ozone Sterilization.
D. Hydrogen Peroxide Plasma ($\text{H P P}$).
Correct Answer: D. Hydrogen Peroxide Plasma ($\text{H P P}$).
Rationale: $\text{H P P}$ is incompatible with materials containing cellulose (cotton, paper) because the plasma
chemistry degrades cellulose fibers, compromising the packaging barrier.
