  1. An autoclave sterilization cycle for wrapped surgical instruments is set at 121°C (250°F). What is the minimum exposure time required at this temperature?

    Answer: 15 minutes

    The standard steam autoclave gravity-displacement cycle at 121°C requires a minimum of 15 minutes of exposure time after the chamber reaches temperature to achieve sterilization of wrapped instruments.

  2. Which OSHA standard requires employers to provide hepatitis B vaccination to employees with occupational exposure to bloodborne pathogens?

    Answer: OSHA Bloodborne Pathogen Standard (29 CFR 1910.1030)

    OSHA's Bloodborne Pathogen Standard (29 CFR 1910.1030) requires employers to offer hepatitis B vaccination at no cost to all employees with occupational exposure within 10 days of job assignment.

  3. Which of the following best describes the chain of infection and which link, if broken, would MOST efficiently prevent healthcare-associated infections (HAIs)?

    Answer: Pathogen → reservoir → portal of exit → transmission → portal of entry → susceptible host; breaking the transmission link through hand hygiene

    The classic 6-link chain of infection model identifies transmission as the most modifiable link; hand hygiene is the single most effective infection control measure because it interrupts the transfer of pathogens to susceptible hosts.

  4. Which Personal Protective Equipment (PPE) item is required FIRST when donning (putting on) PPE before entering an isolation room?

    Answer: Gown

    The CDC-recommended sequence for donning PPE begins with the gown, which protects clothing and skin; all other PPE (mask/respirator, eye protection, gloves) is applied over the gown.

  5. A medical assistant prepares to perform a venipuncture. After cleansing the site with 70% isopropyl alcohol, how long should the site be allowed to dry before the needle is inserted?

    Answer: 30–60 seconds

    The venipuncture site must be allowed to air dry for 30–60 seconds after alcohol application to allow the antiseptic to exert its full antimicrobial effect and to prevent hemolysis of the sample from residual alcohol.

  6. Which of the following infectious diseases requires BOTH airborne AND contact precautions simultaneously?

    Answer: Varicella (chickenpox)

    Varicella (chickenpox) requires both airborne precautions (because the virus can travel in aerosols) and contact precautions (because direct contact with vesicular lesions can transmit the virus).
