,Question 1
During the primary survey, how is the airway assessed in a trauma patient with a suspected
cervical spine injury?
A) Perform a head-tilt, chin-lift maneuver
B) Perform a jaw-thrust maneuver without head extension
C) Assess the airway only after the cervical collar is removed
D) Blindly sweep the mouth to clear any foreign objects
Rationale: The jaw-thrust maneuver is the recommended method to open the airway in a
trauma patient, as it avoids manipulating the cervical spine. A head-tilt, chin-lift maneuver
can cause cervical spine extension, which is contraindicated in trauma patients with potential
spinal injuries.
Question 2
A patient presents with asymmetrical chest wall movement, diminished breath sounds on the
left side, and tracheal deviation to the right. Which of the following is the priority intervention?
A) Endotracheal intubation
B) Immediate needle decompression on the left side
C) Application of a three-sided occlusive dressing
D) Administration of a fluid bolus
Rationale: These are classic signs of a tension pneumothorax, requiring immediate needle
decompression to convert it into a simple pneumothorax. Intubation will not relieve the
intrathoracic pressure and could worsen hypotension.
Question 3
A trauma patient has an obvious, spurting arterial hemorrhage from a wound on the thigh.
What is the immediate first step in managing this hemorrhage?
A) Apply a sterile gauze pad and tape it securely
B) Elevate the affected limb above the level of the heart
C) Apply a commercial tourniquet proximal to the bleeding site
D) Administer intravenous crystalloid fluids
Rationale: Direct pressure followed by the application of a commercial tourniquet is the gold
standard for life-threatening extremity hemorrhage. Sterile gauze and tape or elevation alone
will not control a spurting arterial bleed.
,Question 4
In the "Disability" section of the primary survey, a patient opens their eyes to pain, withdraws
from a noxious stimulus, and mumbles incomprehensible sounds. What is their Glasgow Coma
Scale (GCS) score?
A) 7
B) 9
C) 6
D) 8
Rationale: Eye opening to pain = 2; Withdraws to pain = 4; Incomprehensible sounds = 2. Total
= 8, which indicates a severe traumatic brain injury requiring definitive airway protection.
Question 5
During the "Exposure and Environment" step of the primary survey, you are working to prevent
the "Triad of Death". Which three conditions make up this triad?
A) Hypothermia, acidosis, and coagulopathy
B) Hypoxia, hypercapnia, and hypovolemia
C) Hypotension, tachycardia, and hypothermia
D) Head injury, hemorrhage, and hypoxia
Rationale: Hypothermia, acidosis, and coagulopathy form the lethal triad in trauma. Each
component exacerbates the others, worsening patient outcomes and increasing mortality.
Question 6
Which of the following is the strongest indication for a definitive airway (e.g., endotracheal
intubation) in an emergency trauma setting?
A) An isolated, closed femur fracture
B) The inability to protect the airway due to a decreased level of consciousness
C) A small, superficial laceration on the forehead
D) A closed head injury with a GCS of 13
Rationale: The inability to protect the airway (e.g., loss of gag reflex, GCS less than or equal to
8) is a primary indication for a definitive airway to prevent aspiration and maintain adequate
oxygenation.
, Question 7
A patient with blunt chest trauma is diagnosed with a flail chest. Which of the following
assessment findings is expected?
A) Tracheal deviation away from the affected side
B) Decreased tidal volume with a shift towards respiratory alkalosis
C) Paradoxical chest wall movement
D) Absent breath sounds over the entire affected hemithorax
Rationale: Flail chest occurs when two or more ribs are fractured in two or more places,
causing a segment of the chest wall to move paradoxically (inward on inspiration, outward on
expiration). Tracheal deviation points to a tension pneumothorax instead.
Question 8
A trauma patient who was involved in an explosion now presents with a suspected open
pneumothorax. What is the immediate nursing intervention?
A) Perform immediate needle decompression at the second intercostal space
B) Secure a tight, four-sided occlusive dressing
C) Leave the wound completely open to the air to prevent pressure buildup
D) Apply a sterile, three-sided occlusive dressing
Rationale: A three-sided occlusive dressing acts as a flutter valve, allowing air to escape the
pleural space during exhalation but preventing air from being sucked in during inhalation. A
tight four-sided dressing can convert it into a life-threatening tension pneumothorax.
Question 9
A patient involved in a high-speed MVC has severe pelvic pain, and instability is noted on
palpation. What is a critical nursing action for managing this patient?
A) Apply a pelvic binder to reduce the pelvic volume and control bleeding
B) Insert a urinary catheter immediately to assess for hematuria
C) Perform a forceful physical examination to determine the extent of instability
D) Position the patient in the Trendelenburg position
Rationale: A pelvic binder is applied to stabilize a suspected pelvic fracture, reduce pelvic
volume, and tamponade retroperitoneal venous bleeding. Forceful or repeated exams can
dislodge clots and worsen hemorrhage.
