CCA CCA Infection Control & Sterilization 2 — Questions and Answers
Question 1: How frequently must prosthetic gloves be replaced during anaplastology fabrication sessions?
- Only when visibly torn
- Between each patient and whenever contamination occurs (Correct answer)
- Once per day regardless of use
- Only when the patient requests new gloves
Correct answer: Between each patient and whenever contamination occurs
Gloves must be changed between patients and whenever contamination occurs to prevent cross-contamination, as they are single-use items.
Question 2: Which surface in the anaplastology lab requires the most frequent disinfection?
- Overhead light sources
- Work surfaces where prostheses are fabricated (Correct answer)
- Storage cabinets
- Ventilation grilles
Correct answer: Work surfaces where prostheses are fabricated
Work surfaces that have direct contact with patient materials require disinfection between each patient use to prevent cross-contamination.
Question 3: When an anaplastologist has an open cut or abrasion on their hand, what is the appropriate action before patient contact?
- Wear double gloves over the wound
- Cover the wound with a waterproof bandage and wear gloves (Correct answer)
- Avoid all patient contact for the day
- Apply topical antibiotic and proceed without gloves
Correct answer: Cover the wound with a waterproof bandage and wear gloves
Wounds must be covered with a waterproof bandage before donning gloves to protect against pathogen exposure and shield the wound from patient materials.
Question 4: Which OSHA standard specifically governs occupational exposure to bloodborne pathogens in anaplastology?
- OSHA 1910.1200 (Hazard Communication)
- OSHA 1910.1030 (Bloodborne Pathogens) (Correct answer)
- OSHA 1910.1000 (Air Contaminants)
- OSHA 1910.134 (Respiratory Protection)
Correct answer: OSHA 1910.1030 (Bloodborne Pathogens)
OSHA Standard 1910.1030 (Bloodborne Pathogens Standard) regulates occupational exposure to blood and other potentially infectious materials in healthcare settings.
Question 5: What type of waste container must be used for disposing of sharps used in anaplastology procedures?
- Regular trash bin
- Biohazard bag
- Puncture-resistant sharps container (Correct answer)
- Sealed plastic bag
Correct answer: Puncture-resistant sharps container
Sharps must be disposed of in puncture-resistant, leak-proof sharps containers labeled with the biohazard symbol to prevent needlestick injuries.
Question 6: What is the purpose of dental/medical-grade mold release agents in anaplastology fabrication?
- They eliminate the need for disinfection
- They prevent materials from sticking to molds during processing (Correct answer)
- They act as antimicrobial barriers between mold and casting material
- They improve color matching of silicone
Correct answer: They prevent materials from sticking to molds during processing
Mold release agents are processing aids that prevent materials from bonding to molds; they do not function as infection control measures and do not replace disinfection.
