Read the first 7 Infection Control & Prevention flashcards as text

  1. A patient with Clostridioides difficile (C. diff) infection is admitted to the ward. Which type of precautions should be implemented in addition to standard precautions?

    Answer: Contact precautions

    C. diff is transmitted via the fecal-oral route through spores on surfaces and hands, requiring contact precautions including gown and gloves.

  2. Which hand hygiene agent is MOST effective against Clostridioides difficile spores?

    Answer: Soap and water

    Alcohol-based hand rubs do not reliably kill C. diff spores; soap and water with friction physically removes spores from hands.

  3. A healthcare worker is caring for a patient on contact precautions. In what order should PPE be removed to prevent self-contamination?

    Answer: Gloves, goggles, gown, mask

    CDC doffing sequence begins with gloves (most contaminated), then goggles/face shield, gown, and finally mask/respirator.

  4. Which of the following is classified as an intermediate-level disinfectant?

    Answer: 70% isopropyl alcohol

    Intermediate-level disinfectants such as 70% isopropyl alcohol inactivate most bacteria, mycobacteria, fungi, and most viruses but not spores.

  5. A nurse must perform a urinary catheter insertion. Which type of technique is required to prevent catheter-associated urinary tract infections (CAUTI)?

    Answer: Aseptic technique

    Aseptic (sterile) technique using sterile gloves, drape, and supplies is required for urinary catheter insertion to prevent CAUTI.

  6. Which of the following is the primary purpose of an infection control risk assessment (ICRA) in healthcare construction projects?

    Answer: To identify and mitigate infection risks from dust and debris during construction

    An ICRA evaluates the risk of airborne pathogens such as Aspergillus from construction dust reaching vulnerable patients and guides containment measures.

  7. A healthcare worker accidentally receives a needlestick injury from an HIV-positive patient's needle. What is the FIRST action that should be taken?

    Answer: Wash the wound thoroughly with soap and water

    The immediate first step is to wash the wound with soap and water for several minutes to reduce pathogen load before reporting and considering PEP.
