CHAM-2026: ATLS Advanced Trauma Prep with
Detailed Clinical Rationales
Course Code: NR-446
Course Name: High-Acuity Nursing Care and Advanced Trauma Support
Topic: Advanced Trauma Life Support (ATLS), Hemorrhagic Shock, and
Secondary Injury Prevention
Academic Year: 2026/2027
Question 1
A trauma nurse receives an adult client who was ejected from a moving vehicle.
The client has an unstable pelvic ring fracture, a rapid, thready pulse, and a
blood pressure of 82/40 mm Hg. The client's face is anasen-gray, and their
extremities are cool and pale. Which of the following therapeutic compounds is
strictly contraindicated in the initial management of this client's hemorrhagic
shock?
A. Type O-negative packed red blood cells (pRBCs).
B. Isotonic crystalloid solution warmed to 39°C (102.2°F).
C. Continuous intravenous vasopressor infusions such as norepinephrine.
D. Infusion of uncrossmatched fresh frozen AB plasma.
CORRECT ANSWER: C
RATIONALE: In the initial resuscitation of hemorrhagic shock, vasopressors
are strictly contraindicated. Vasopressors induce severe, artificial peripheral
vasoconstriction, which falsely elevates systemic blood pressure while severely
worsening tissue perfusion, accelerating cellular hypoxia, and intensifying
metabolic acidosis. The definitive treatment for hypovolemic trauma shock is
volume replacement using warmed isotonic crystalloids and blood products to
restore oxygen-carrying capacity and intravascular volume.
Question 2
A nurse in the emergency department is assessing an adult male client who was
crushed between a loading dock and a truck. The nurse notes blood present at the
urethral meatus and extensive perineal ecchymosis. Which of the following
,actions should the nurse execute immediately?
A. Lubricate and insert a standard 16-French transurethral Foley catheter into the
bladder.
B. Withhold transurethral bladder catheterization and prepare the client for a
retrograde urethrogram.
C. Instruct the client to try to void in a sterile specimen cup to check for
microscopic hematuria.
D. Apply a tight compression dressing to the perineum to tamponade the
underlying bleeding.
CORRECT ANSWER: B
RATIONALE: The presence of blood at the urethral meatus or perineal
ecchymosis provides clear physical evidence of a urethral injury. In this clinical
scenario, standard transurethral bladder catheterization is strictly
contraindicated due to the high risk of converting a partial urethral tear into a
complete transection. The nurse must withhold catheterization and ensure a
retrograde urethrogram is performed first to confirm urethral integrity.
Question 3
A nurse is assessing a client who was involved in a high-speed, head-on motor
vehicle collision. The client is tachycardic, hypotensive, and has distended neck
veins. Upon auscultation, the heart sounds are distant and muffled, but the lungs
are completely clear and equal bilaterally with normal resonance to percussion.
The nurse should identify that these findings are diagnostic of which condition?
A. Massive tension pneumothorax.
B. Acute cardiac tamponade.
C. Traumatic left-sided hemothorax.
D. Profound neurogenic spinal shock.
CORRECT ANSWER: B
RATIONALE: Distant, muffled heart sounds, hypotension, and distended neck
veins comprise Beck's triad, which is diagnostic of acute cardiac tamponade.
Because the lungs remain clear and equal bilaterally with normal percussion, a
tension pneumothorax or hemothorax can be ruled out (a tension pneumothorax
would feature absent breath sounds and hyperresonance). On an ECG, cardiac
,tamponade, tension pneumothorax, and profound hypovolemia are major causes of
pulseless electrical activity (PEA).
Question 4
A nurse is caring for an adult client who has sustained severe closed
circumferential thermal injuries to the bilateral lower extremities and abdomen.
The client's heart rate is rising, and peripheral pulses in the distal feet are becoming
progressively faint and difficult to Doppler. The nurse should anticipate which of
the following definitive surgical interventions?
A. Immediate emergency laparotomy.
B. An escharotomy performed at the bedside.
C. Insertion of a continuous intraosseous line into the proximal tibia.
D. Immediate administration of high-dose intravenous sodium bicarbonate.
CORRECT ANSWER: B
RATIONALE: Circumferential full-thickness burns create a tough, non-elastic
leathery band of tissue (eschar) that acts as a tourniquet as edema develops beneath
it. This causes extremity or truncal compartment syndrome. The definitive
treatment for a full-thickness burn presenting with vascular compromise is an
immediate escharotomy to cut through the dead tissue, relieve the pressure, and
restore blood flow.
Question 5
A nurse is calculating the APGAR score for a newborn at 5 minutes after birth.
The newborn has a completely pink body, a heart rate of 115/min, displays a
vigorous, strong cry with coughing when stimulated, maintains fully flexed
extremities, and exhibits active, crying respirations. The nurse should document an
APGAR score of which of the following?
A. 7
B. 8
C. 9
D. 10
CORRECT ANSWER: D
RATIONALE: The APGAR score is calculated based on five criteria, each
, worth 0 to 2 points: Appearance (skin color): 2 points for being completely pink.
Pulse (heart rate): 2 points for >100/min. Grimace (reflex irritability): 2 points for
a vigorous cry, cough, or sneeze during stimulation. Activity (muscle tone): 2
points for full flexion and active movement. Respiration (effort): 2 points for a
strong, lusty cry. 2 + 2 + 2 + 2 + 2 = 10, which indicates an optimal transitional
state.
Question 6
A nurse is evaluating a client who has sustained a severe blunt chest injury. The
client’s chest wall exhibits asymmetric movement where a segment of the chest
sinks inward during inspiration and balloons outward during expiration. The nurse
should recognize this as a flail chest and prioritize monitoring the client for which
of the following secondary complications?
A. Autonomic dysreflexia.
B. Severe hypoxemia and pulmonary contusion.
C. Transesophageal fistula formation.
D. High-output cardiac failure.
CORRECT ANSWER: B
RATIONALE: A flail chest occurs when multiple adjacent ribs are fractured in
two or more places, creating a free-floating, paradoxical chest segment. The
underlying force that causes a flail chest almost always results in a severe
pulmonary contusion (bruising of the lung tissue). This combination causes
hypoxia, which is the most serious consequence of chest trauma. The nurse must
monitor for rapid respiratory decompensation, progressively shallow respirations,
and dropping oxygen saturations.
Question 7
A nurse is preparing to administer an intermittent tube feeding to an adult client
who has a decreased level of consciousness (LOC) following a stroke. To
promote gastric emptying and minimize the risk of aspiration, the nurse should
position the client into which of the following configurations?
A. On the client's right side with the head of the bed elevated.
B. On the client's left side with the bed maintained flat.
