Comprehensive and Detailed Explanation From Exact Extract:

The first step in hemorrhage control for external bleeding is always direct pressure using gloved hands or dressing. Only if this fails or the bleeding is severe and life-threatening (especially from extremities) should a tourniquet be applied.

Assessing the airway is critical in overall trauma care but not the first priority in isolated extremity hemorrhage. Severity assessment is secondary to bleeding control.

According to Pediatric Basic Life Support (PBLS) guidelines by the American Heart Association (AHA), when a child becomes unresponsive due to foreign body airway obstruction (FBAO), the immediate next step is to begin chest compressions. This is done before checking the airway or giving breaths because the airway is presumed obstructed. The compressions may dislodge the object.

After 30 compressions, open the airway and check for visible objects. If none are seen, attempt rescue breaths. This protocol reflects the high risk of complete airway blockage in children with sudden collapse following a choking episode.

Comprehensive and Detailed Explanation (Based on NREMT standards):

This scenario strongly suggests a hazardous environment involving chemical crowd-control agents such as tear gas or pepper spray. During the scene survey, NREMT prioritizes scene safety, hazard recognition, and incident size-up before any patient contact.

Option D (Determine the control agent being used) is correct because identifying the chemical agent helps determine the level of risk, appropriate personal protective equipment, and whether EMS can safely operate in the area.

Option E (Identify the number of patients) is correct because determining the number of patients is essential for assessing the scope of the incident and requesting additional resources if needed.

Option A is incorrect because removing restraints is not part of the initial scene survey and must be coordinated with law enforcement.

Option B is incorrect because patient decontamination occurs only after scene safety is ensured.

Option C is not a priority until hazards are identified and the scene is safe.

NREMT teaches that EMTs must never compromise their own safety and must fully assess hazards before providing care.

Comprehensive and Detailed Explanation From Exact Extract:

To establish negligence, four legal elements must be proven:

Duty to act – a legal obligation to provide care.

Breach of duty – failing to meet the standard of care.

Damages – harm occurred.

Proximate causation – the breach directly caused the damage.

"Proximate causation" means the EMT’s action or inaction is closely linked to the harm suffered by the patient.
