TNCC 9TH EDITION FINAL EXAM PREP
BANK QUESTIONS WITH DETAILED
ANSWERS AND RATIONALES (NEWEST
ACTUAL EXAM STUDY GUIDE)
This premium, high-density study resource features a
comprehensive bank of up-to-date, multiple-choice questions
meticulously aligned with the TNCC 9th Edition core
curriculum. Every single question provides direct answers
alongside exhaustive, bold-italicised rationales that break
down critical primary survey protocols, MARCH algorithms,
neurotrauma interventions, and special population care. It
serves as an indispensable tool for emergency nurses
aiming to ace their certification exam on the first attempt
and boost their clinical readiness.
1. Uncontrolled Hemorrhage Prioritization
During the initial assessment of a trauma patient, a large, spurting wound is
noted on the right thigh. Which letter of the March/ABCDE mnemonic
should the nurse address first?
A) A – Airway
B) C – Circulation
C) H – Hemorrhage control
D) M – Massive hemorrhage
,Answer: D
Rationale: The TNCC 9th edition emphasizes the "MARCH" algorithm
in the initial assessment phase, which prioritizes Massive
Hemorrhage control before Airway. Tourniquet application or direct
pressure to a catastrophic bleed must occur immediately to prevent
exsanguination before addressing the airway.
2. Definitive Airway Identification
Which of the following maintains a definitive airway for a trauma patient?
A) Nasopharyngeal airway
B) Laryngeal mask airway (LMA)
C) Cuffed endotracheal tube in the trachea
D) Oropharyngeal airway
Answer: C
Rationale: A definitive airway requires a tube placed securely in the
trachea with the cuff inflated, connected to an oxygen-enriched
ventilation system. Oral and nasal airways, as well as LMAs, are
temporary adjuncts and do not protect against aspiration.
3. Needle Decompression Landmark
A patient presents with a tension pneumothorax. Where is the preferred
anatomical landmark for needle decompression in an adult patient?
A) 2nd intercostal space, midclavicular line
B) 5th intercostal space, anterior axillary line
C) 4th intercostal space, midaxillary line
D) 3rd intercostal space, midclavicular line
Answer: B
Rationale: Current evidence-based guidelines in advanced trauma
care support the 5th intercostal space at the anterior axillary line as
the primary site for adults due to a thinner chest wall thickness
compared to the 2nd intercostal space midclavicular line.
,4. Flail Chest Paradoxical Motion
A patient with multiple rib fractures exhibits paradoxical chest wall
movement. What is the immediate physiological threat to this patient?
A) Metabolic alkalosis
B) Hypoventilation and hypoxia
C) Increased cardiac output
D) Decreased airway resistance
Answer: B
Rationale: Flail chest occurs when two or more adjacent ribs are
fractured in two or more places. The paradoxical motion increases the
work of breathing, leading to rapid shallow breaths, splinting, severe
hypoventilation, and progressive hypoxia.
5. Beck's Triad Components
The nurse suspects cardiac tamponade in a patient with a penetrating
chest wound. Which assessment findings constitute Beck's Triad?
A) Hypertension, bradycardia, irregular respirations
B) Hypotension, muffled heart tones, jugular venous distention
C) Hypotension, tachycardia, wheezing
D) Hypertension, distended neck veins, clear breath sounds
Answer: B
Rationale: Beck's Triad is the classic triad of signs associated with
cardiac tamponade: muffled heart sounds (due to fluid in the
pericardial sac), hypotension (due to decreased stroke volume), and
jugular venous distention (due to increased venous backpressure).
6. Cushing's Triad Interpretation
A patient with a severe traumatic brain injury demonstrates an elevated
systolic blood pressure, widened pulse pressure, bradycardia, and irregular
respirations. What do these signs indicate?
, A) Hypovolemic shock
B) Neurogenic shock
C) Increased intracranial pressure (ICP)
D) Early signs of sepsis
Answer: C
Rationale: Cushing's Triad (widening pulse pressure/systolic
hypertension, bradycardia, and irregular respirations) is a late sign of
significantly increased intracranial pressure and impending brain
herniation.
7. Le Fort II Fracture Assessment
A patient presents with midface mobility, epistaxis, and bilateral periorbital
ecchymosis. The fracture line extends through the nasal bones and the
maxillary sinus. Which type of facial fracture is this?
A) Le Fort I
B) Le Fort II
C) Le Fort III
D) Mandibular dislocation
Answer: B
Rationale: A Le Fort II fracture is pyramidal in shape and involves the
maxilla, nasal bones, and medial orbital walls. Le Fort I is limited to
the maxilla above the teeth, while Le Fort III involves complete
craniofacial disjunction.
8. Cerebral Perfusion Pressure (CPP) Calculation
A neuro-trauma patient has a Mean Arterial Pressure (MAP) of 85 mmHg
and an Intracranial Pressure (ICP) of 15 mmHg. What is the patient’s
Cerebral Perfusion Pressure?
A) 100 mmHg
B) 60 mmHg
