Initial Assessment & Primary Survey (Questions 1-15)
Question 1
The primary survey in trauma follows which systematic approach? A)
ABCDE B) SAMPLE C) OPQRST D) PQRST
Answer: A) ABCDE Rationale: Primary survey follows ABCDE approach -
Airway with c-spine protection, Breathing, Circulation, Disability
(neurologic), and Exposure/Environmental control.
Question 2
During the primary survey, life-threatening conditions are: A)
Identified but treated during secondary survey B) Identified and treated
immediately C) Documented for later treatment D) Referred to the
physician only
Answer: B) Identified and treated immediately Rationale: Life-
threatening conditions identified during primary survey must be treated
immediately before proceeding.
Question 3
The most common preventable cause of death in trauma patients is:
A) Hemorrhage B) Airway obstruction C) Pneumothorax D) Head injury
,Answer: B) Airway obstruction Rationale: Airway obstruction is the
most common preventable cause of death in trauma, emphasizing
airway priority.
Question 4
C-spine immobilization should be maintained until: A) X-rays are
completed B) Patient is stable C) C-spine injury is ruled out clinically or
radiographically D) 24 hours have passed
Answer: C) C-spine injury is ruled out clinically or radiographically
Rationale: C-spine precautions continue until injury is definitively ruled
out through clinical criteria or imaging.
Question 5
The Glasgow Coma Scale assesses: A) Eye opening, verbal response,
motor response B) Pupil reaction, motor response, vital signs C)
Orientation, memory, speech D) Reflexes, sensation, movement
Answer: A) Eye opening, verbal response, motor response Rationale:
GCS evaluates three components: eye opening (4 points), verbal
response (5 points), motor response (6 points).
Question 6
A GCS score of 8 or less indicates: A) Mild head injury B) Moderate
head injury C) Severe head injury D) No neurologic impairment
Answer: C) Severe head injury Rationale: GCS ≤8 indicates severe head
injury and typically requires intubation for airway protection.
Question 7
, The "golden hour" concept refers to: A) The first hour after hospital
arrival B) The first hour after injury occurrence C) Time for definitive
surgical intervention D) Recovery time in ICU
Answer: B) The first hour after injury occurrence Rationale: The
"golden hour" emphasizes the critical first hour after trauma when
prompt treatment can significantly improve outcomes.
Question 8
Mechanism of injury is important because it: A) Determines insurance
coverage B) Helps predict injury patterns C) Establishes legal liability D)
Affects family notification
Answer: B) Helps predict injury patterns Rationale: Understanding
mechanism helps anticipate specific injuries and guides assessment
priorities.
Question 9
High-energy mechanisms include: A) Fall from standing height B) Motor
vehicle crash >40 mph C) Low-speed bicycle accident D) Sports injury
Answer: B) Motor vehicle crash >40 mph Rationale: High-energy
mechanisms (MVC >40 mph, falls >20 feet, pedestrian vs. vehicle)
suggest greater injury potential.
Question 10
The secondary survey includes: A) ABCDE assessment B) Head-to-toe
physical examination C) Vital signs only D) History taking only
Answer: B) Head-to-toe physical examination Rationale: Secondary
survey is systematic head-to-toe examination after primary survey is
complete and patient is stable.
