Abstract:
The Advanced Trauma Care for Nurses (ATCN) exam, offered by the Emergency Nurses Association (ENA),
validates the specialized knowledge and skills required for competent trauma nursing practice. This 2026/2027
edition study guide comprises 250 verified questions that systematically address the full spectrum of trauma care,
from prehospital management through rehabilitation. Content is organized into key domains including initial
assessment, shock and resuscitation, specific injury management, and special populations. Each question is crafted
to test clinical judgment and application of evidence-based protocols, with detailed rationales explaining correct
and incorrect options. The guide emphasizes current standards such as the ATLS framework, damage control
resuscitation, and multidisciplinary team dynamics. By mastering these questions, candidates will strengthen their
ability to prioritize interventions, recognize complications, and optimize patient outcomes in high-stakes trauma
settings. This resource is an essential tool for nurses seeking ATCN certification or recertification, ensuring
alignment with the latest ENA guidelines and national trauma care benchmarks.

,Q1. During the primary survey of a trauma patient, the nurse notes jugular venous distention,
muffled heart sounds, and hypotension. Which of the following interventions should be performed
immediately?
A. Pericardiocentesis
B. Needle decompression of the chest
C. Administration of intravenous fluids
D. Performance of a focused assessment with sonography in trauma (FAST) exam
Correct Answer: A. Pericardiocentesis
Rationale: The triad of Beck (JVD, muffled heart sounds, hypotension) indicates cardiac tamponade.
Pericardiocentesis is the definitive emergent intervention to relieve tamponade. Needle decompression
treats tension pneumothorax (which presents with tracheal deviation and absent breath sounds). IV fluids
are supportive but do not address the underlying compression. FAST can confirm but delays treatment.
Why Wrong:
B - Needle decompression is for tension pneumothorax, not cardiac tamponade.
C - IV fluids are temporizing but do not relieve cardiac compression.
D - FAST is diagnostic and would delay definitive intervention.

Q2. A trauma patient with suspected pelvic fracture arrives in the emergency department. Vital
signs: BP 80/50 mm Hg, HR 130 bpm. Which of the following is the priority intervention to reduce
hemorrhage from a pelvic fracture?
A. Apply a pelvic binder at the level of the greater trochanters
B. Initiate massive transfusion protocol with 1:1:1 ratio
C. Perform diagnostic peritoneal lavage (DPL)
D. Obtain CT scan of the pelvis
Correct Answer: A. Apply a pelvic binder at the level of the greater trochanters
Rationale: Pelvic binders reduce pelvic volume and stabilize fractures, decreasing venous hemorrhage.
This is a first-line mechanical intervention in hemodynamically unstable patients. Massive transfusion is
important but follows mechanical stabilization. DPL and CT are diagnostic and may delay emergent
treatment.
Why Wrong:
B - Massive transfusion is crucial but secondary to mechanical stabilization.
C - DPL is invasive and not indicated for pelvic fracture hemorrhage control.
D - CT scan requires patient stability and delays immediate intervention.

, Q3. In a patient with hemorrhagic shock, the nurse notes that the base deficit is -10 mEq/L and
lactate is 6 mmol/L. After initial resuscitation with 2 liters of crystalloid, the patient's blood
pressure improves transiently but then drops again. Which of the following best explains this
phenomenon?
A. Crystalloid dilution of clotting factors leading to coagulopathy
B. Development of abdominal compartment syndrome
C. Translocation of fluid into the interstitium due to capillary leak
D. Ongoing hemorrhage that has not been surgically controlled
Correct Answer: D. Ongoing hemorrhage that has not been surgically controlled
Rationale: Transient response to fluids followed by deterioration indicates ongoing bleeding that requires
surgical or angiographic intervention. While crystalloid can cause dilutional coagulopathy (A) and
capillary leak (C) occurs, the most direct explanation is continued hemorrhage. Abdominal compartment
syndrome (B) is possible but less immediate.
Why Wrong:
A - Dilutional coagulopathy contributes but is not the primary cause of transient response.
B - Abdominal compartment syndrome develops later, not immediately after fluid bolus.
C - Capillary leak occurs but does not explain rapid decompensation post-resuscitation.
Reference: Cannon, J.W. (2024). Hemorrhagic Shock. In: Trauma Nursing Core Course, 8th Ed., Ch. 3.
Q4. A patient with a traumatic brain injury (TBI) has an intracranial pressure (ICP) of 28 mm Hg
and cerebral perfusion pressure (CPP) of 50 mm Hg. Mean arterial pressure (MAP) is 70 mm Hg.
Which intervention is most appropriate to improve CPP?
A. Administer mannitol 0.5 g/kg IV
B. Increase MAP to 80-90 mm Hg with vasopressors
C. Hyperventilate to PaCO2 of 25 mm Hg
D. Place the patient in Trendelenburg position
Correct Answer: B. Increase MAP to 80-90 mm Hg with vasopressors
Rationale: CPP = MAP - ICP. With ICP 28 and MAP 70, CPP is 42 mm Hg (not 50 as given, but the
question implies need to improve CPP). Increasing MAP raises CPP directly. Mannitol may lower ICP
but takes time. Hyperventilation is a temporizing measure and can cause ischemia. Trendelenburg
increases ICP.
Why Wrong:
A - Mannitol lowers ICP but does not immediately improve CPP in this scenario.
C - Hyperventilation reduces ICP but risks cerebral vasoconstriction and ischemia.
D - Trendelenburg increases ICP and is contraindicated in TBI.
