Sample Certified Hyperbaric Technician Practice Questions

Try these questions from our free Certified Hyperbaric Technician practice tests. The correct answer and an explanation follow each question.

  1. How should reusable equipment be disinfected?

    • A. By rinsing with water.
    • B. Using EPA-registered disinfectants per protocol
    • C. By spraying air freshener.
    • D. By storing it dry.

Answer: B. Using EPA-registered disinfectants per protocol

Reusable medical equipment must be meticulously disinfected using EPA-registered disinfectants according to established protocols to eliminate pathogens and prevent cross-contamination. Following manufacturer guidelines and facility-specific procedures ensures that the disinfectants are effective against a broad spectrum of microorganisms. This practice is fundamental to maintaining a sterile environment and protecting patient safety in hyperbaric settings.

  • Gas gangrene (clostridial myonecrosis) benefits from HBOT because:

    • A. High pressure physically destroys Clostridium spores
    • B. Hyperoxia is directly bacteriostatic/bactericidal to anaerobic Clostridium and inhibits alpha-toxin production
    • C. HBOT replaces the need for emergent surgical debridement
    • D. Oxygen prevents further gas formation in infected tissue
  • Answer: B. Hyperoxia is directly bacteriostatic/bactericidal to anaerobic Clostridium and inhibits alpha-toxin production

    High tissue oxygen tensions are toxic to obligate anaerobes like Clostridium perfringens and inhibit alpha-toxin production, making HBOT a valuable adjunct to surgery and antibiotics.

  • According to CMS Conditions of Participation, a hospital-based hyperbaric program must maintain treatment records for a minimum of how many years for adult patients?

    • A. 3 years
    • B. 5 years
    • C. 7 years
    • D. 10 years
  • Answer: B. 5 years

    CMS requires hospital records, including hyperbaric treatment records for adults, to be retained for at least 5 years from the date of discharge.

  • A patient refuses a recommended hyperbaric oxygen treatment session. What is the technician's primary ethical obligation?

    • A. Administer the treatment anyway to protect the patient's health
    • B. Document the refusal and notify the supervising physician
    • C. Discharge the patient immediately from the program
    • D. Convince the patient by overstating treatment risks of refusal
  • Answer: B. Document the refusal and notify the supervising physician

    Documenting the refusal and notifying the physician respects patient autonomy while ensuring proper medical oversight and legal protection.
