Scenarios Study Guide

SECTION 1: SCENE ASSESSMENT AND SAFETY (Questions 1–20)


Question 1
You are dispatched to a report of a person down in an alley. Upon arrival, you see
a patient lying motionless near a downed power line. What is the FIRST action you
should take?
A. Approach the patient and begin assessment
B. Ensure the power line is de-energized before approaching
C. Call for additional resources and wait
D. Move the patient away from the power line
Answer: B
Rationale: Scene safety is always the first priority. A downed power line presents
an immediate threat to both the responder and the patient. The power line must be
de-energized by the utility company before anyone approaches. Approaching the
patient (A) or moving them (D) risks electrocution. Calling for resources (C) is
important but does not address the immediate hazard.


Question 2
You arrive at a residence for a medical call. As you approach the door, you hear
shouting and sounds of a physical altercation inside. What is the MOST
appropriate action?
A. Enter immediately to assess the patient
B. Retreat to a safe distance and request law enforcement

,C. Knock loudly and announce your presence
D. Wait in the ambulance until the noise stops
Answer: B
Rationale: When there are signs of violence or an unsafe environment, the EMR
should retreat to a safe distance and request law enforcement assistance. Entering
(A) or knocking (C) could place the responder in danger. Waiting in the ambulance
(D) without requesting law enforcement delays the response.


Question 3
Which of the following is the MOST important personal protective equipment
(PPE) for an EMR responding to a suspected infectious disease call?
A. Helmet
B. Gloves, gown, mask, and eye protection
C. Steel-toed boots
D. Fire-resistant clothing
Answer: B
Rationale: For a suspected infectious disease call, standard precautions include
gloves, gown, mask, and eye protection. A helmet (A) is for rescue operations.
Steel-toed boots (C) and fire-resistant clothing (D) are for specific hazards but do
not protect against infectious diseases.


Question 4
You are called to a scene where a patient has been exposed to an unknown
chemical. What is the FIRST priority?
A. Decontaminate the patient
B. Identify the chemical
C. Ensure scene safety and don appropriate PPE
D. Begin patient assessment
Answer: C
Rationale: For a hazardous materials incident, the first priority is scene safety,
including ensuring the scene is safe and donning appropriate PPE.

,Decontamination (A) and patient assessment (D) occur after the scene is secured.
Identifying the chemical (B) is helpful but secondary to safety.


Question 5
Which of the following is a sign that a scene may be unsafe?
A. Patient is conscious and alert
B. Strong chemical odor
C. Bystanders are calm
D. Weather is clear
Answer: B
Rationale: A strong chemical odor may indicate a hazardous materials release and
an unsafe scene. A conscious patient (A), calm bystanders (C), and clear weather
(D) are not indicators of an unsafe scene.


Question 6
You are dispatched to a motor vehicle collision on a highway. What is the FIRST
step upon arrival?
A. Assess the patient
B. Park your vehicle to protect the scene
C. Call for additional resources
D. Begin extrication
Answer: B
Rationale: Upon arrival at a motor vehicle collision, the first step is to position
your vehicle to protect the scene and prevent secondary collisions. This includes
using warning lights and cones. Patient assessment (A), calling for resources (C),
and extrication (D) follow scene safety.


Question 7
Which of the following is the correct sequence for assessing a scene?
A. Assess the patient, then the scene
B. Assess the scene, then the patient

, C. Assess both simultaneously
D. Assess the patient only
Answer: B
Rationale: The correct sequence is to assess the scene for safety hazards before
approaching the patient. This includes looking for environmental hazards,
violence, and other dangers. Assessing the patient first (A) places the responder at
risk.


Question 8
You are called to a scene where a patient has fallen from a ladder. The patient is
complaining of neck pain. What is the FIRST priority?
A. Apply a cervical collar
B. Ensure scene safety
C. Assess the patient's airway
D. Move the patient to the ambulance
Answer: B
Rationale: Scene safety is always the first priority. The EMR should ensure the
scene is safe (e.g., no electrical hazards from the ladder) before approaching the
patient. A cervical collar (A) and airway assessment (C) follow scene safety.
Moving the patient (D) should only be done if there is an immediate threat.


Question 9
Which of the following is a component of scene size-up?
A. Determining the mechanism of injury
B. Obtaining a medical history
C. Performing a detailed physical exam
D. Administering medications
Answer: A
Rationale: Scene size-up includes determining the mechanism of injury (MOI) or
nature of illness (NOI), assessing the number of patients, and identifying any
