PHTLS Scene Assessment and Safety 2

Question 1

During a multi-vehicle collision at night, which action best protects EMS providers while maintaining patient access?

Accepted Answer

Position the ambulance at an angle upstream with warning lights activated

Answer

Positioning the ambulance at an angle upstream (fend-off position) with lights on protects providers from traffic while maintaining scene access.

Question 2

A provider arrives at a shooting scene where the suspect is reportedly still in the area. What is the correct action?

Accepted Answer

Stage at a safe location and await law enforcement clearance

Answer

EMS must stage at a safe distance until law enforcement secures the scene before entering any active threat environment.

Question 3

Which of the following best describes 'scene size-up' in PHTLS?

Accepted Answer

A continuous process of evaluating hazards, MOI, patient count, and resources throughout the response

Answer

Scene size-up is a dynamic, ongoing process that begins with dispatch and continues throughout the entire response.

Question 4

At a confined-space rescue with a trapped worker, which hazard takes highest priority before entry?

Accepted Answer

Verifying atmospheric oxygen levels and toxic gas concentrations

Answer

Atmospheric testing for oxygen deficiency and toxic gases is mandatory before entering any confined space to prevent rescuer incapacitation.

Question 5

A provider is caring for a patient when bystanders become increasingly agitated and aggressive. What is the most appropriate response?

Accepted Answer

Reassess scene safety and prepare to relocate care if needed

Answer

Scene safety must be continuously reassessed; a deteriorating bystander situation may require relocating patient care operations.
