Read the first 7 Safety and Infection Control flashcards as text

  1. Which type of isolation is used for patients with airborne-transmitted diseases such as tuberculosis?

    Answer: Airborne isolation

    Airborne isolation requires a negative-pressure room and N95 respirators to prevent spread of pathogens that travel on small particles.

  2. What is the FIRST step a healthcare worker should take when they suspect a patient has a healthcare-associated infection (HAI)?

    Answer: Notify the charge nurse or supervisor

    Notifying the charge nurse ensures proper clinical assessment and infection control protocols are initiated promptly.

  3. A sharps container should be replaced when it is filled to what level?

    Answer: 75%

    Sharps containers must be replaced when three-quarters full to prevent overfilling, which increases the risk of needlestick injuries.

  4. Which pathogen is most commonly associated with ventilator-associated pneumonia (VAP)?

    Answer: Pseudomonas aeruginosa

    Pseudomonas aeruginosa is a leading gram-negative pathogen responsible for ventilator-associated pneumonia in ICU settings.

  5. When removing personal protective equipment (PPE) after caring for a patient on contact precautions, which item is removed LAST?

    Answer: Hand hygiene

    Hand hygiene is the final step after all PPE is removed to eliminate any residual contamination transferred during doffing.

  6. Which cleaning agent is considered the gold standard for eliminating Clostridium difficile spores from surfaces?

    Answer: Bleach (sodium hypochlorite) solution

    C. difficile spores are resistant to alcohol and many disinfectants; only bleach-based solutions reliably destroy them on environmental surfaces.

  7. A healthcare worker accidentally splashes blood into their eye. What is the IMMEDIATE action?

    Answer: Flush the eye with sterile saline or water for 15 minutes

    Immediate irrigation of the mucous membrane with water or saline for at least 15 minutes is the first response to blood or body fluid splash to the eye.
