  3. Which of the following best describes the chain of infection?

    Answer: Pathogen → portal of exit → mode of transmission → portal of entry → susceptible host

  4. Which hand hygiene technique is specifically required when caring for a patient with Clostridioides difficile?

  5. What is the purpose of an exposure control plan (ECP) in the laboratory?

    Answer: To outline procedures for eliminating or minimizing bloodborne pathogen exposure

    An ECP is required by OSHA's Bloodborne Pathogen Standard and documents how the facility will protect workers from occupational exposure.

  6. Which of the following is an example of an engineering control used to reduce needle-stick injuries?

    Answer: Using safety-engineered needles with retractable shields

    Safety-engineered devices such as retractable or shielded needles are engineering controls that physically reduce the risk of accidental puncture.

  7. A laboratory specimen labeled 'biohazardous' arrives without a lid on the transport tube. What should the lab assistant do first?

    Answer: Don PPE and re-cap or contain the specimen before handling further

    Donning PPE and containing the open specimen first protects the worker and prevents environmental contamination.
