CCA Infection Control & Sterilization Flashcards

What is the recommended method for disinfecting silicone facial prostheses?

Answer: Wiping with isopropyl alcohol and air drying

Silicone prostheses cannot withstand autoclaving temperatures, so isopropyl alcohol wipe-down is the standard disinfection method.

Which disinfectant is classified as high-level and approved for use on prosthetic impression materials that cannot be autoclaved?

Answer: 2% glutaraldehyde solution

2% glutaraldehyde is a high-level disinfectant effective against all microorganisms except high numbers of bacterial spores, making it suitable for heat-sensitive impression materials.

What is the primary purpose of barrier precautions during prosthetic fabrication?

Answer: To prevent cross-contamination between patient and practitioner

Barrier precautions (gloves, masks, gowns) prevent cross-contamination and protect both patient and clinician from infectious agents.

How should impressions be handled before pouring stone models in the anaplastology lab?

Answer: Disinfected with an appropriate disinfectant spray or immersion

Impressions must be disinfected before laboratory handling to prevent pathogen transmission to the lab environment, per CDC guidelines.

Which infection control standard applies to ALL patients regardless of known infection status in anaplastology practice?

Answer: Standard precautions

Standard precautions apply universally to all patients regardless of diagnosis and form the foundation of infection control in healthcare.

What is the correct procedure for disposing of contaminated impression materials in a clinical anaplastology setting?

Answer: Rinse, disinfect, and double-bag before disposal

Contaminated impression materials are biohazardous waste and must be rinsed, disinfected, and double-bagged per OSHA regulations.
