Standard And Transmission-Based Precautions - NCLEX Pn

1. Which disease is classically placed on Droplet Precautions: influenza, varicella, or C. difficile?

   Influenza. Influenza spreads via large respiratory droplets that travel short distances, making droplet precautions appropriate.

2. What is the primary purpose of Standard Precautions in all patient care settings?

   Prevent transmission of infection from blood and all body fluids. Standard Precautions are designed to reduce the risk of pathogen transmission by treating all blood and body fluids as potentially infectious in every healthcare interaction.

3. Which transmission-based precaution category is used for pathogens spread by large droplets?

   Droplet precautions. Droplet precautions target infections like influenza that spread via large particles generated during coughing or sneezing.

4. What PPE is routinely required for Droplet Precautions when within close range of the patient?

   Surgical mask (add eye protection if splash risk). A surgical mask filters large droplets, with eye protection added to shield mucous membranes from potential splashes.

5. Identify the correct action after a needlestick exposure to blood in a healthcare worker.

   Wash area, report immediately, and follow post-exposure protocol. Prompt washing removes contaminants, while reporting initiates evaluation and prophylaxis for bloodborne exposures.

6. Which PPE is required when there is risk of splash or spray to face or clothing?

   Gloves, gown, and mask with eye protection (goggles or face shield). These items provide barrier protection against splashes of blood or body fluids that could contact mucous membranes or nonintact skin.

7. Which method is required when hands are visibly soiled or after caring for C. difficile?

   Soap and water handwashing. Soap and water mechanically remove soil and spore-forming organisms like C. difficile that are resistant to alcohol-based sanitizers.

8. What is the preferred patient transport guidance for Contact Precautions?

   Limit transport; cover infected areas and maintain clean gown/linen. Covering infected areas during transport minimizes environmental contamination and direct contact risks.

9. What is the preferred patient transport guidance for Droplet Precautions?

   Limit transport; place a surgical mask on the patient during transport. Limiting transport and masking the patient contain large droplets, preventing spread in shared healthcare spaces.

10. What type of mask is required for Airborne Precautions?

    Fit-tested N95 respirator (or higher-level respirator). N95 respirators filter small airborne particles, providing respiratory protection against inhalable infectious aerosols.

11. Which diseases require Airborne Precautions: tuberculosis, measles, or influenza?

    Tuberculosis and measles. Tuberculosis and measles produce small droplet nuclei that remain airborne, necessitating enhanced isolation measures.

12. Which body substances are treated as potentially infectious under Standard Precautions?

    All blood and body fluids except sweat; nonintact skin; mucous membranes. Under Standard Precautions, these substances are universally considered potentially infectious to protect healthcare workers from bloodborne pathogens.

13. Which organism requires Contact Precautions plus soap-and-water hand hygiene: MRSA, RSV, or C. difficile?

    C. difficile. C. difficile spores resist alcohol and require mechanical removal via soap and water to prevent contact transmission.

14. Which transmission-based precaution category is used for pathogens spread by airborne droplet nuclei?

    Airborne precautions. Airborne precautions address pathogens like tuberculosis that remain suspended in air and can be inhaled over distances.

15. What type of room is required for a patient on Airborne Precautions?

    Airborne infection isolation room (negative pressure). Negative pressure rooms prevent contaminated air from escaping, ensuring safe isolation of airborne pathogens.

16. What is the correct order to don PPE for isolation precautions?

    Gown, mask or respirator, goggles or face shield, then gloves. This sequence ensures protective barriers are applied from least to most contaminated areas, minimizing self-contamination during donning.

17. What is respiratory hygiene or cough etiquette intended to prevent?

    Spread of respiratory pathogens via droplets and contaminated hands/surfaces. Respiratory hygiene practices block the dissemination of infectious respiratory particles, reducing transmission in healthcare settings.

18. What is the single most effective action to prevent healthcare-associated infection transmission?

    Hand hygiene at the correct times. Proper hand hygiene disrupts the chain of infection by removing transient microorganisms that can transfer between patients and surfaces.

19. Which transmission-based precaution category is used for pathogens spread by direct or indirect contact?

    Contact precautions. Contact precautions prevent transmission of organisms like MRSA through direct touch or contact with contaminated environments.

20. Which option best describes when to perform hand hygiene during patient care?

    Before/after patient contact and after contact with body fluids or contaminated items. These moments align with the World Health Organization's 'My 5 Moments for Hand Hygiene' to minimize pathogen transmission during care.

21. What PPE is routinely required upon room entry for a patient on Contact Precautions?

    Gown and gloves. Gown and gloves create a barrier to prevent direct contact with infectious materials or colonized skin surfaces.

22. What is the key sharps safety rule for used needles?

    Do not recap; dispose immediately in a puncture-resistant sharps container. Immediate disposal without recapping prevents accidental needlestick injuries, a primary source of bloodborne pathogen exposure.

23. What is the correct minimum time for alcohol-based hand rub to be effective?

    Rub for at least 20 seconds until hands are dry. Alcohol-based rubs require sufficient contact time to denature proteins and inactivate a broad spectrum of microorganisms on the skin.

24. What is the preferred patient transport guidance for Airborne Precautions?

    Limit transport; place a surgical mask on the patient during transport. Masking the patient during necessary transport contains infectious aerosols, reducing airborne transmission risks.

25. What is the correct order to remove PPE to reduce self-contamination risk?

    Gloves, goggles or face shield, gown, mask or respirator; then hand hygiene. This removal order prevents contaminants from transferring to clean areas, with hand hygiene ensuring any residual pathogens are eliminated.
