Scene Safety and Personal Protective Equipment - NREMT EMT Level

1. Which condition must be met before you enter a scene with potential hazards?

   The scene must be safe, or made safe, for rescuers. Prevents rescuers from becoming additional victims by prioritizing their safety.

2. Which PPE is indicated for suspected droplet-spread infections such as influenza or meningitis?

   A surgical mask (add eye protection if splash risk). Blocks large respiratory droplets, with added protection against splashes if needed.

3. Which item is removed last during PPE doffing when leaving a contaminated patient care area?

   Mask or respirator. Minimizes risk of self-contamination by removing it last after other items.

4. Which hazard category includes risks such as downed power lines, unstable structures, and traffic?

   Environmental and physical hazards. Involves external factors that could cause injury or impede safe operations.

5. Which hazard category includes risks such as toxic chemicals, gases, and unknown powders?

   Hazardous materials (HazMat) hazards. Pertains to substances posing chemical or toxic risks requiring specialized handling.

6. What should you do if blood splashes into your eye while providing patient care?

   Irrigate immediately, report exposure, and follow protocol. Flushes contaminants from mucous membranes to limit absorption and infection.

7. Identify the term for protection against hazards to rescuers and bystanders at an EMS scene.

   Scene safety. Refers to assessing and mitigating risks to maintain a secure environment for EMS operations.

8. Which action is required immediately after removing gloves, even if the gloves appear intact?

   Perform hand hygiene. Eliminates potential microbes that may have penetrated or contaminated skin.

9. Identify the correct order for doffing PPE to reduce self-contamination.

   Gloves, eye protection, gown, mask/respirator. Reduces contamination by removing outer layers first per standard protocols.

10. Which PPE item is the minimum standard when there is any possibility of contact with body fluids?

    Gloves. Serves as the primary barrier to prevent transmission of pathogens via direct contact.

11. What should you do if a patient's blood contacts your broken skin during care?

    Immediately wash, report exposure, and follow agency protocol. Cleans the area to reduce infection risk and ensures proper medical follow-up.

12. Which statement best defines standard precautions for EMS providers?

    Treat all blood and body fluids as potentially infectious. Applies universal precautions to minimize exposure to bloodborne pathogens.

13. Which hazard category includes risks such as violence, weapons, and hostile crowds?

    Scene security hazards. Encompasses threats to personal safety requiring law enforcement intervention.

14. Which scene size-up finding most strongly indicates you should stage and wait for law enforcement?

    Evidence or report of violence or weapons present. Indicates high risk of violence, necessitating secure scene before entry.

15. What does BSI stand for in the context of infection control and PPE selection?

    Body substance isolation. Describes practices assuming all body substances are infectious to guide PPE and infection control.

16. Which action should you take when approaching a motor vehicle crash on a roadway?

    Position the ambulance to protect the scene and use warning devices. Creates a safe zone to prevent further accidents and facilitate scene management.

17. Which PPE should you add when there is a risk of blood or body fluid splashes to the face?

    Eye protection and a mask (or a face shield). Shields mucous membranes from potential splashes, reducing infection risk during procedures.

18. Which PPE should you use for suspected airborne diseases such as tuberculosis?

    A fit-tested N95 respirator (or higher). Provides respiratory protection by filtering airborne pathogens to prevent inhalation.

19. Identify the correct order for donning PPE in routine patient care.

    Gown, mask/respirator, eye protection, gloves. Follows CDC guidelines to minimize contamination risk during application.

20. What does the term "mechanism of injury" (MOI) mean during scene size-up?

    The forces that caused trauma to the patient. Helps predict injury patterns by evaluating the energy transfer in trauma.

21. What is the first action you must take on arrival to any emergency scene?

    Perform a scene size-up for safety before patient contact. Ensures identification of hazards to protect responders before initiating patient care.

22. What does the term "nature of illness" (NOI) mean during scene size-up?

    The general type of medical problem the patient has. Guides assessment by identifying the underlying medical condition category.

23. What is the single most effective method to prevent transmission of infection in EMS care?

    Hand hygiene. Removes pathogens from hands, breaking the chain of infection effectively.

24. What is the best general rule for selecting PPE when the exposure risk is uncertain?

    Use the highest level of PPE reasonably anticipated. Errs on the side of caution to ensure adequate protection based on potential exposures.

25. Identify the safest immediate action if you suspect a HazMat release at the scene.

    Do not enter; retreat and wait for HazMat-trained responders. Avoids untrained exposure to dangerous materials, ensuring responder safety.
