INTRODUCTION
This advanced Trauma Nurse Specialist (TNS) practice set is designed to reinforce the
clinical reasoning required for complex trauma nursing practice. Questions emphasize
rapid assessment, prioritization, hemodynamic interpretation, injury-pattern
recognition, resuscitation principles, multidisciplinary coordination, complication
prevention, and evidence-based trauma care. The difficulty progresses from advanced
application to highly complex clinical decision-making, with emphasis on situations in
which multiple interventions appear reasonable but one represents the safest priority.
Learners should expect scenarios involving hemorrhagic shock, traumatic brain injury,
thoracic and abdominal trauma, burns, orthopedic injuries, pediatric and geriatric
trauma, and systems-level considerations. The material is intended for advanced
professional study and should be interpreted alongside current institutional protocols
and applicable trauma-care standards.
Question 1
A 29-year-old patient arrives after a high-speed motor-vehicle collision. The patient has
severe pelvic pain, cool mottled skin, a heart rate of 138/min, blood pressure of 82/48
mmHg, and altered mentation. A pelvic binder has been applied. There is no obvious
external hemorrhage. Which finding most strongly supports ongoing occult
hemorrhagic shock despite the absence of visible bleeding?
A. Oxygen saturation of 98% on supplemental oxygen
B. Persistent tachycardia with worsening peripheral perfusion and altered mentation
C. Mild abdominal tenderness without guarding
D. Respiratory rate of 20/min with equal breath sounds
,🔴 Correct Answer: B. Persistent tachycardia with worsening peripheral perfusion
and altered mentation.
🔵 Explanation: Persistent tachycardia, peripheral vasoconstriction, altered mentation,
and hypotension strongly suggest inadequate tissue perfusion from significant blood loss.
Pelvic fractures can produce substantial concealed hemorrhage into the retroperitoneal
and pelvic spaces.
Question 2
A patient with penetrating chest trauma develops severe respiratory distress,
hypotension, distended neck veins, and markedly diminished breath sounds on the
right. The trachea appears slightly deviated to the left. Which intervention should the
trauma nurse anticipate as the immediate priority?
A. Portable chest radiograph before intervention
B. Needle or finger thoracostomy followed by definitive chest drainage
C. Administration of a diuretic
D. Endotracheal intubation before treating the thoracic injury
🔴 Correct Answer: B. Needle or finger thoracostomy followed by definitive chest
drainage.
🔵 Explanation: The combination of respiratory distress, hypotension, unilateral absent
breath sounds, and obstructive physiology is highly concerning for tension pneumothorax.
In an unstable patient, decompression should not be delayed for diagnostic imaging.
Question 3
A patient with severe traumatic brain injury has an intracranial pressure of 24 mmHg
and a cerebral perfusion pressure of 52 mmHg despite adequate oxygenation and
normocapnia. Which nursing priority is most appropriate?
A. Maintain the patient completely flat
B. Reduce cerebral perfusion pressure to prevent cerebral edema
C. Collaborate on interventions aimed at reducing intracranial pressure while
maintaining adequate cerebral perfusion
D. Induce prolonged hypocapnia as the primary treatment
🔴 Correct Answer: C. Collaborate on interventions aimed at reducing intracranial
pressure while maintaining adequate cerebral perfusion.
🔵 Explanation: Elevated ICP combined with inadequate CPP threatens cerebral
,perfusion. Management should address the elevated ICP while preserving systemic and
cerebral perfusion. Prolonged prophylactic hyperventilation can worsen cerebral ischemia
and is not routine therapy.
Question 4
A trauma patient initially responds to crystalloid administration but subsequently
becomes hypotensive again. The patient has a suspected splenic injury and worsening
abdominal distention. Which interpretation is most appropriate?
A. The transient response confirms dehydration as the primary cause
B. Recurrent hypotension suggests ongoing hemorrhage requiring definitive
hemorrhage control
C. Additional crystalloid alone is the preferred definitive treatment
D. Abdominal distention rules out intra-abdominal bleeding
🔴 Correct Answer: B. Recurrent hypotension suggests ongoing hemorrhage
requiring definitive hemorrhage control.
🔵 Explanation: A transient hemodynamic response followed by recurrent instability is
concerning for ongoing blood loss. In a patient with suspected solid-organ injury,
definitive hemorrhage control and balanced blood-product resuscitation may be more
important than continued large-volume crystalloid administration.
Question 5
A patient with blunt thoracic trauma has multiple rib fractures and increasing work of
breathing. The patient is initially alert but becomes increasingly fatigued. Which finding
should most strongly influence escalation of respiratory support?
A. Pain score of 7/10
B. Increasing respiratory effort with deteriorating mental status and inadequate
ventilation
C. Bruising over the chest wall
D. Heart rate of 104/min
🔴 Correct Answer: B. Increasing respiratory effort with deteriorating mental status
and inadequate ventilation.
🔵 Explanation: Respiratory fatigue and altered mental status indicate impending
ventilatory failure. Rib fractures can produce significant splinting, atelectasis, impaired
secretion clearance, and respiratory compromise, requiring timely escalation of support.
, Question 6
A patient with a suspected cervical spinal injury becomes hypotensive and bradycardic
after blunt trauma. The skin is warm rather than cool and clammy. Which mechanism is
most consistent with these findings?
A. Hemorrhagic shock
B. Neurogenic shock caused by loss of sympathetic vascular tone
C. Cardiogenic shock caused by myocardial infarction
D. Obstructive shock from tension pneumothorax
🔴 Correct Answer: B. Neurogenic shock caused by loss of sympathetic vascular
tone.
🔵 Explanation: Neurogenic shock can occur after significant spinal cord injury and is
characterized by hypotension with relative bradycardia and loss of peripheral
vasoconstriction. Hemorrhage must still be aggressively excluded in trauma.
Question 7
A patient with severe abdominal trauma is initially hemodynamically stable but
develops increasing abdominal pressure, oliguria, rising airway pressures, and
worsening ventilation several hours later. Which complication should the trauma nurse
suspect?
A. Acute compartment syndrome of the extremity
B. Abdominal compartment syndrome
C. Isolated neurogenic shock
D. Simple postoperative ileus
🔴 Correct Answer: B. Abdominal compartment syndrome.
🔵 Explanation: Increasing intra-abdominal pressure can impair renal perfusion, venous
return, diaphragmatic excursion, and pulmonary mechanics. The combination of oliguria,
increased airway pressures, and progressive abdominal distention is characteristic of
abdominal compartment physiology.
Question 8
A patient with a crush injury to the lower extremity has severe pain, tense swelling, and
pain that increases dramatically with passive stretching. Distal pulses remain palpable.
Which conclusion is most appropriate?
