comprehensive, high-yield final exam study package. This emergency nursing resource
delivers a thorough breakdown of the Trauma Nursing Process (TNP) A-I mnemonic,
advanced airway management, shock resuscitation protocols, and specific injury
mechanisms. Eliminate testing anxiety and master high-stakes clinical decision-making
using realistic case-based practice questions modeled directly after the official ENA 9th
edition blueprin
QUESTION 1
What is the first priority in the primary survey of a trauma patient?
A) Assess circulation with hemorrhage control
B) Assess airway with cervical spine protection
C) Assess disability (GCS)
D) Expose and examine the patient
Answer: B) Assess airway with cervical spine protection
Rationale: The ABCDE approach begins with Airway assessment while maintaining
cervical spine immobilization. A compromised airway is the most immediate threat
to life and must be addressed first .
QUESTION 2
What is the key to a high-performing trauma team?
A) Individual goals
B) Use of the SBAR tool
C) Identification of a single decision maker
D) Consistent communication
Answer: D) Consistent communication
,Rationale: Consistent communication is the cornerstone of a high-performing
trauma team. Clear, closed-loop communication ensures all team members
understand roles, findings, and interventions .
QUESTION 3
Which of the following is the most reliable indicator of a patent airway in an
unresponsive trauma patient?
A) Ability to speak
B) Presence of breath sounds
C) Chest rise with bag-valve-mask ventilation
D) Absence of stridor
Answer: A) Ability to speak
Rationale: A patient who can speak clearly has a patent airway. For unresponsive
patients, assess for foreign bodies, vomitus, or edema. Speech requires air
movement through the vocal cords .
QUESTION 4
The "Jaw-thrust" maneuver is preferred over head-tilt/chin-lift in trauma patients
because:
A) It is easier to perform
B) It maintains cervical spine alignment
C) It provides better visualization of the airway
D) It requires less training
Answer: B) It maintains cervical spine alignment
Rationale: The jaw-thrust maneuver is preferred because it opens the airway while
maintaining cervical spine motion restriction, reducing the risk of spinal cord
injury in trauma patients .
,QUESTION 5
The major preventable cause of death in the trauma patient is:
A) Airway compromise
B) Ineffective ventilation
C) Secondary head injury
D) Uncontrolled hemorrhage
Answer: D) Uncontrolled hemorrhage
Rationale: Uncontrolled external hemorrhage is the leading cause of preventable
death after injury, particularly in the prehospital environment. Assessment to
identify uncontrolled external hemorrhage is key to the initial assessment process .
QUESTION 6
What is the appropriate technique to palpate the pelvis for stability?
A) Apply gentle pressure over the iliac wings downward and laterally
B) Apply gentle pressure over the iliac wings downward and medially
C) Apply firm pressure over the iliac wings downward and laterally
D) Apply firm pressure over the iliac wings downward and medially
Answer: B) Apply gentle pressure over the iliac wings downward and medially
Rationale: Gentle pressure over the iliac wings downward and medially assesses
pelvic stability. Firm or aggressive palpation may disrupt a pelvic fracture and
exacerbate hemorrhage .
QUESTION 7
, A patient involved in a high-speed rollover is complaining of increased difficulty
breathing. There is a small penetrating wound to the sixth intercostal space in the left
lateral chest. Which finding is most consistent with an injury to the diaphragm?
A) Bowel sounds heard in the left lower chest
B) Severe left-sided abdominal pain
C) Pain radiating to the left shoulder
D) Decreased breath sounds on the left side
Answer: A) Bowel sounds heard in the left lower chest
Rationale: Diaphragmatic rupture allows abdominal contents (such as bowel) to
herniate into the thoracic cavity. Bowel sounds heard in the chest are a classic
finding of diaphragmatic injury .
QUESTION 8
Which of the following is the best measure of the adequacy of cellular perfusion and
helps to predict the outcome of resuscitation?
A) End-tidal carbon dioxide
B) Hypoxia
C) Base deficit
D) Oxygen saturation
Answer: C) Base deficit
Rationale: Base deficit is the best measure of the adequacy of cellular perfusion
and helps predict resuscitation outcome. It reflects the degree of metabolic acidosis
from hypoperfusion .
QUESTION 9
A patient with a spinal cord injury at C5 is being cared for in the emergency department.
Which of the following represents the highest priority for ongoing assessment?
