TNCC PRACTICE TEST MASTER BANK 2026–
2027 EXAM QUESTIONS, ANSWERS AND
VERIFIED RATIONALES
This comprehensive question master practice exam features
verified multiple-choice questions, accurate answers, and
detailed rationales matching the 2026–2027 TNCC standards.
It systematically reviews the entire Trauma Nursing Process,
including the Primary Survey sequence, shock resuscitation,
and neurological trauma assessments like the Glasgow
Coma Scale. Perfect for emergency nurses looking to pass
their certification on the first attempt, this high-yield
document is designed to maximize student success and
academic performance.
1. What is the very first step in the TNCC trauma nursing
process primary survey?
A) Assess for airway patency
B) Check a carotid pulse
C) Control massive external hemorrhage
D) Establish large-bore IV access
Correct Answer: C
Rationale: The primary survey begins with a rapid scan for
uncontrolled, massive hemorrhage (the "C" before "A" in the
catastrophic hemorrhage paradigm). If life-threatening
,bleeding is present, it must be stopped with direct pressure
or a tourniquet immediately before treating the airway.
2. A trauma patient arrives with an obviously occluded
airway. Which initial intervention is prioritized?
A) Perform an immediate surgical cricothyroidotomy
B) Position the airway using a modified jaw-thrust maneuver
C) Insert a nasopharyngeal airway in a patient with midface
fractures
D) Initiate mechanical ventilation at a rate of 25 breaths per
minute
Correct Answer: B
Rationale: The modified jaw-thrust maneuver is the preferred
initial method to open the airway of a trauma patient because
it minimizes movement of the cervical spine. Advanced
surgical options or mechanical adjuncts are secondary to
manual positioning.
3. Which position is most beneficial to optimize airway
patency and ventilation in a severely obese trauma patient?
A) Supine with flat head-of-bed
B) Prone with neck extended
C) Trendelenburg position
D) Reverse Trendelenburg position
Correct Answer: D
Rationale: The reverse Trendelenburg position utilizes
gravity to pull abdominal contents downward, reducing
,pressure on the diaphragm. This enhances lung expansion
and improves oxygenation parameters in obese patients.
4. While evaluating a patient during the "B" component of the
primary survey, you note a trachea deviated to the right and
absent breath sounds on the left. What is the immediate
nursing action?
A) Obtain a portable stat chest X-ray
B) Prepare for immediate needle decompression on the left
C) Increase the oxygen flow rate on the nasal cannula
D) Intubate the patient with an endotracheal tube
Correct Answer: B
Rationale: These symptoms indicate a life-threatening
tension pneumothorax. Needle decompression must be
performed immediately based on clinical findings alone,
without waiting for diagnostic imaging like a chest X-ray.
5. What is the preferred fluid choice for initial volume
resuscitation in a trauma patient exhibiting hemorrhagic
shock?
A) 5% Dextrose in Water (D5W)
B) 0.45% Normal Saline
C) Balanced crystalloids or warmed blood products
D) Albumin 25% solution
Correct Answer: C
Rationale: Warmed balanced crystalloids (like Lactated
Ringer's) or immediate blood components are preferred to
, mitigate the lethal triad of trauma (hypothermia,
coagulopathy, acidosis). Hypotonic fluids like D5W cause
cellular swelling and worsen outcomes.
6. A patient presents with a fractured second rib on the right
side. The nurse must monitor closely for signs of which
associated injury?
A) Brachial plexus injury
B) Splenic rupture
C) Diaphragmatic tear
D) Pelvic fracture
Correct Answer: A
Rationale: Fractures of the upper ribs (1st and 2nd) require
high-force impacts and are frequently associated with major
neurovascular trauma, specifically injuries to the brachial
plexus or the subclavian vessels.
7. During the "D" phase of the primary survey, you evaluate a
patient's Glasgow Coma Scale (GCS). The patient opens eyes
to pain, speaks in incomprehensible words, and withdraws
from pain. What is the GCS score?
A) 6
B) 8
C) 10
D) 12
Correct Answer: B
Rationale: Eye-opening to pain = 2; Incomprehensible words
