What is the primary purpose of the Exposure Control Plan required by OSHA's Bloodborne Pathogen Standard?
Answer: To eliminate or minimize employee exposure to bloodborne pathogens
The Exposure Control Plan's primary purpose is to eliminate or minimize occupational exposure to bloodborne pathogens through engineering controls, work practices, and PPE.
Which hepatitis virus is most commonly transmitted via contaminated needles and is a significant occupational risk for healthcare workers?
Answer: Hepatitis B
Hepatitis B virus (HBV) is highly transmissible via needlestick injuries and is the primary vaccine-preventable bloodborne pathogen risk for healthcare workers.
A sharps container should be replaced when it is how full?
Answer: Three-quarters (75%) full
Sharps containers must be replaced when three-quarters (75%) full to prevent overfilling, which increases the risk of needlestick injury during disposal.
Which hand hygiene method is preferred when hands are visibly soiled with blood or body fluids?
Answer: Soap and water wash for at least 20 seconds
When hands are visibly soiled, soap and water must be used because alcohol-based hand rubs cannot physically remove organic material from the skin.
The term 'engineering controls' in infection control refers to:
Answer: Physical modifications that isolate or remove hazards such as needle-retraction devices
Engineering controls are physical or mechanical devices — such as needleless systems or sharps disposal containers — that remove or isolate bloodborne pathogen hazards.
When cleaning a blood spill on a countertop, what is the minimum recommended concentration of sodium hypochlorite (bleach) solution?
Answer: 1:10 dilution (approximately 5,000 ppm)
A 1:10 bleach solution (approximately 5,000 ppm available chlorine) is the CDC-recommended minimum for decontaminating blood spills on surfaces.
Which of the following actions represents correct 'doffing' (removing) sequence for PPE?
Answer: Remove gloves, then eye protection, then gown, then mask or respirator
The correct doffing sequence is gloves first (most contaminated), then eye protection, then gown, and finally the mask or respirator to prevent self-contamination.
