Module 1: Emergency Nursing, Triage, and
Trauma Care (Questions 1–10)
Q1. A 34-year-old victim of a motor vehicle
collision arrives in the emergency department
unresponsive with gurgling respirations. What is
the priority nursing action during the primary
survey?
A) Administer 100% oxygen via a non-rebreather
mask
B) Perform manual cervical spine stabilization and
suction the airway with a rigid tonsil-tip catheter
C) Assist with immediate endotracheal intubation
D) Obtain a stat arterial blood gas (ABG)
Rationale: The primary survey always follows the
ABCDE hierarchy. Gurgling respirations indicate
,a mechanical airway obstruction by fluids or
blood. Suctioning must be performed
immediately while maintaining manual cervical
spine immobilization to prevent worsening a
potential spinal cord injury.
Q2. During a mass casualty incident (MCI) triage,
a nurse assesses a victim who has a sucking
chest wound, a respiratory rate of 28
breaths/min, and a palpable radial pulse. Which
color tag should the nurse assign to this
patient?
A) Green
B) Yellow
C) Red
D) Black
Rationale: A red tag (Immediate) is assigned to
patients who have life-threatening injuries that
are treatable with immediate, minimal
intervention. A sucking chest wound severely
compromises breathing but is rapidly survivable
if addressed immediately with an occlusive
dressing and chest tube.
Q3. A patient presents to the emergency
department after falling from a 20-foot scaffold.
The nurse notes ecchymosis around the eyes
,(raccoon eyes) and behind the mastoid process
(Battle’s sign). Which clear fluid drainage should
the nurse test for the presence of glucose?
A) Sputum
B) Otorrhea or rhinorrhea
C) Gastric secretions
D) Profuse diaphoresis
Rationale: Raccoon eyes and Battle’s sign are
classic physical assessment findings indicating
a basilar skull fracture. Drainage of clear fluid
from the ears (otorrhea) or nose (rhinorrhea)
represents cerebrospinal fluid (CSF) leakage,
which can be confirmed by a positive glucose
test or a "halo sign" on gauze.
Q4. A client is admitted to the emergency
department with a suspected tension
pneumothorax. Which assessment finding
should the nurse anticipate as a hallmark sign of
this condition?
A) Decreased heart rate and hypertension
B) Bounding peripheral pulses and clear lung
sounds
C) Tracheal deviation to the unaffected side and
absent breath sounds on the affected side
D) Paradoxical chest wall movement during
, inspiration
Rationale: A tension pneumothorax involves
rapid air accumulation in the pleural space that
cannot escape. This exerts extreme pressure on
the mediastinum, shifting structures away from
the affected lung, resulting in tracheal deviation,
compressed vena cava, absent breath sounds on
the injured side, and obstructive shock.
Q5. A trauma patient arrives in the ED with a flail
chest. The nurse observes paradoxical chest
wall movement. Which pathophysiological
change describes this movement?
A) The injured chest wall segment sucks in during
inspiration and balloons out during expiration
B) The entire chest expands symmetrically but
causes extreme agonizing pain
C) The diaphragm paralyzes completely, stopping all
accessory muscle use
D) The trachea shifts toward the side of the injured
ribs during exhalation
Rationale: Flail chest occurs when two or more
adjacent ribs are fractured in two or more places,
creating a free-floating chest wall segment. This
segment moves opposite to normal mechanics
due to intrapleural pressure changes: pulling
