CLT Infection Control & Sterilization in Laser Therapy 1 — Questions and Answers
Question 1: What is the primary purpose of infection control protocols in a laser therapy practice?
- To reduce total treatment time per session
- To prevent transmission of pathogens between patients and practitioners (Correct answer)
- To improve the efficiency of the laser device
- To enhance photobiomodulation outcomes
Correct answer: To prevent transmission of pathogens between patients and practitioners
Infection control protocols exist to prevent the transmission of infectious pathogens between patients, staff, and the clinical environment.
Question 2: Which personal protective equipment (PPE) is considered MOST critical for a laser therapist during a treatment session?
- Latex gloves only
- Wavelength-specific optical safety goggles (Correct answer)
- A standard surgical mask only
- Prescription reading glasses
Correct answer: Wavelength-specific optical safety goggles
Wavelength-specific safety goggles are paramount because laser radiation can cause irreversible retinal damage in a fraction of a second.
Question 3: What is the correct protocol for managing laser probes between patient uses?
- Wipe with a dry lint-free cloth
- Clean with soap and water only
- Disinfect per manufacturer guidelines and applicable infection control standards (Correct answer)
- Rinse briefly under running water
Correct answer: Disinfect per manufacturer guidelines and applicable infection control standards
Manufacturer-specified cleaning and disinfection procedures ensure the probe material is preserved while achieving the required microbial reduction.
Question 4: According to the Spaulding Classification, what level of disinfection is required for a non-critical laser probe that only contacts intact, unbroken skin?
- Full sterilization
- High-level disinfection
- Low-level or intermediate-level disinfection (Correct answer)
- No disinfection is necessary
Correct answer: Low-level or intermediate-level disinfection
Non-critical items contacting only intact skin present the lowest infection risk and require only low-level or intermediate-level disinfection.
Question 5: When treating a patient with an open wound in the target area, what additional infection control measures should a CLT implement?
- Proceed with no additional precautions since laser light is inherently sterile
- Use sterile gloves and single-use probe covers or sterile barrier sheaths (Correct answer)
- Discontinue the treatment session entirely
- Increase laser power output to reduce treatment contact time
Correct answer: Use sterile gloves and single-use probe covers or sterile barrier sheaths
Open wounds compromise the skin's natural barrier, requiring sterile gloves and disposable probe covers to prevent introducing pathogens into the wound.
Question 6: Which cleaning agent should be used on environmental contact surfaces (treatment table, equipment controls) between patient sessions?
- Soap and water only
- An EPA-registered hospital-grade disinfectant (Correct answer)
- A dry microfiber cloth
- Isopropyl alcohol diluted below 30%
Correct answer: An EPA-registered hospital-grade disinfectant
EPA-registered hospital-grade disinfectants are validated to kill target pathogens on environmental surfaces and meet regulatory infection control requirements.
Question 7: What is the correct hand hygiene sequence when transitioning from one patient to the next?
- Keep the same gloves on and proceed directly to the next patient
- Remove gloves, perform hand hygiene, then don fresh gloves for the next patient (Correct answer)
- Change gloves only at the start and end of each clinical day
- Wash hands only if visibly contaminated with blood or body fluids
Correct answer: Remove gloves, perform hand hygiene, then don fresh gloves for the next patient
Removing gloves and performing hand hygiene before donning new gloves eliminates any pathogens that may have penetrated microscopic glove defects.
