,Q1. During the primary survey, a patient with blunt chest trauma has absent breath sounds on the
left, hypotension, and distended neck veins. After needle decompression is performed, the patient's
oxygen saturation remains low. What is the most appropriate next step?
A. Repeat needle decompression at a different site
B. Perform tube thoracostomy
C. Obtain a chest X-ray before further intervention
D. Initiate fluid resuscitation with warmed crystalloid
Correct Answer: B. Perform tube thoracostomy
Rationale: In tension pneumothorax, if needle decompression fails to improve oxygenation, definitive
management with tube thoracostomy is indicated. Repeat needle decompression is less reliable than tube
thoracostomy, and delaying intervention for imaging can be fatal. Fluid resuscitation is secondary to
airway and breathing interventions.
Why Wrong:
A - Repeat needle decompression may be attempted but is less definitive than tube thoracostomy in
this scenario.
C - Obtaining a chest X-ray delays definitive management in a patient with persistent hypoxia after
needle decompression.
D - Fluid resuscitation does not address the underlying pathophysiology of tension pneumothorax
and should not precede tube thoracostomy.

Q2. A trauma patient with suspected intra-abdominal injury is hemodynamically unstable despite
initial fluid resuscitation. Which diagnostic modality is most appropriate for immediate evaluation?
A. Diagnostic peritoneal lavage (DPL)
B. Focused Assessment with Sonography in Trauma (FAST)
C. Contrast-enhanced computed tomography (CT) of the abdomen and pelvis
D. Exploratory laparotomy
Correct Answer: B. Focused Assessment with Sonography in Trauma (FAST)
Rationale: FAST is the preferred initial test in hemodynamically unstable patients with suspected
intra-abdominal injury because it is rapid, noninvasive, and can detect free fluid. DPL is more invasive
and time-consuming; CT requires stability and transport; exploratory laparotomy is reserved for positive
FAST or high suspicion with instability.
Why Wrong:
A - DPL is invasive and time-consuming, making it less suitable for immediate evaluation in the
unstable patient.
C - CT requires patient stability and transport, which is contraindicated in hemodynamic instability.
D - Exploratory laparotomy is indicated only if FAST is positive or if there is high clinical suspicion
and instability.

, Q3. Which of the following best describes the ATLS classification of hemorrhagic shock based on
initial vital signs and estimated blood loss?
A. Class I: heart rate normal, blood pressure normal, pulse pressure normal, blood loss up to 15%
B. Class II: heart rate >120, blood pressure decreased, pulse pressure narrowed, blood loss 30-40%
C. Class III: heart rate >140, blood pressure decreased, pulse pressure narrowed, blood loss >40%
D. Class IV: heart rate >140, blood pressure decreased, pulse pressure narrowed, blood loss >40%
Correct Answer: A. Class I: heart rate normal, blood pressure normal, pulse pressure normal,
blood loss up to 15%
Rationale: ATLS Class I shock involves up to 15% blood loss with minimal vital sign changes. Class II
(15-30%) shows tachycardia and narrowed pulse pressure. Class III (30-40%) presents with significant
tachycardia, hypotension, and altered mental status. Class IV (>40%) is immediately life-threatening with
marked tachycardia and hypotension.
Why Wrong:
B - Class II heart rate is typically >100 but <120, and blood pressure is usually normal; the described
parameters match Class III.
C - Class III blood loss is 30-40%, not >40%; heart rate is >120, not necessarily >140.
D - Class IV blood loss is >40%, but heart rate >140 and severe hypotension are consistent;
however, the description 'pulse pressure narrowed' is also seen in Class III.

Q4. A patient with a severe facial injury and suspected cervical spine injury requires definitive
airway management. Which of the following is the most appropriate approach?
A. Orotracheal intubation with manual in-line stabilization
B. Nasotracheal intubation without cervical spine manipulation
C. Surgical cricothyroidotomy under local anesthesia
D. Blind nasotracheal intubation with cervical collar removal
Correct Answer: A. Orotracheal intubation with manual in-line stabilization
Rationale: Orotracheal intubation with manual in-line stabilization is the preferred method for emergent
airway management in patients with suspected cervical spine injury. It allows direct visualization and
minimizes cervical movement. Nasotracheal intubation is contraindicated in severe facial trauma due to
risk of intracranial passage.
Why Wrong:
B - Nasotracheal intubation is contraindicated in severe facial trauma due to risk of entering the
cranial vault.
C - Surgical cricothyroidotomy is reserved for failed intubation or contraindications to orotracheal
intubation.
D - Blind nasotracheal intubation is not recommended in trauma due to high failure rate and risk of
complications.
