,Q1. A patient with blunt chest trauma presents with respiratory distress, tracheal deviation to the
right, and absent breath sounds on the left. After immediate decompression, chest tube insertion
yields a gush of air and 200 mL of blood. Vital signs: BP 90/60, HR 120, RR 32, SpO2 88% on 15 L
NRB. Which intervention is most critical next?
A. Obtain a portable chest X-ray to confirm tube placement
B. Prepare for autotransfusion and request 4 units of packed red blood cells
C. Perform a focused assessment with sonography in trauma (FAST) exam
D. Administer 2 liters of isotonic crystalloid rapidly
Correct Answer: B. Prepare for autotransfusion and request 4 units of packed red blood cells
Rationale: The patient has a tension pneumothorax with hemorrhagic output (hemopneumothorax). After
decompression, ongoing hemorrhage requires blood product resuscitation. Autotransfusion is
appropriate for hemothorax. Crystalloid alone is insufficient; massive transfusion protocol should be
initiated. Chest X-ray and FAST are important but delaying blood products increases mortality.
Why Wrong:
A - Chest X-ray is indicated but does not address the immediate hemorrhagic shock.
C - FAST is useful but does not replace the need for blood products in active hemorrhage.
D - Isotonic crystalloid is a temporizing measure; blood products are needed for hemorrhage control.

Q2. Which of the following best describes the rationale for permissive hypotension in the initial
resuscitation of a trauma patient with uncontrolled hemorrhage?
A. It maintains organ perfusion by maximizing cardiac output through increased preload.
B. It minimizes rebleeding by avoiding clot disruption until surgical control is achieved.
C. It reduces the risk of transfusion-related acute lung injury (TRALI) by limiting blood products.
D. It facilitates oxygen delivery by shifting the oxyhemoglobin dissociation curve to the right.
Correct Answer: B. It minimizes rebleeding by avoiding clot disruption until surgical control is
achieved.
Rationale: Permissive hypotension (target systolic 80-90 mmHg) is recommended in hemorrhagic shock
before definitive hemorrhage control to avoid dislodging soft clots. Elevated blood pressure can worsen
bleeding. Option A is incorrect because permissive hypotension does not maximize preload; it restricts
volume. Option C is not the primary rationale. Option D describes the Bohr effect, not the goal of
permissive hypotension.
Why Wrong:
A - Permissive hypotension actually limits volume resuscitation, not maximizes preload.
C - TRALI risk reduction is a secondary benefit, not the primary rationale.
D - The Bohr effect is unrelated to the blood pressure target in hemorrhagic shock.

, Q3. A patient involved in a high-speed motor vehicle collision arrives awake and alert with a
Glasgow Coma Scale (GCS) score of 15. Primary survey reveals no immediately life-threatening
injuries. During the secondary survey, the patient develops acute-onset confusion, left-sided
weakness, and a dilated right pupil. Which of the following is the most likely underlying
mechanism?
A. Cerebral edema from diffuse axonal injury
B. Expanding epidural hematoma from a torn middle meningeal artery
C. Subdural hematoma from tearing of bridging veins
D. Subarachnoid hemorrhage from ruptured aneurysm
Correct Answer: B. Expanding epidural hematoma from a torn middle meningeal artery
Rationale: The lucid interval followed by rapid neurologic decline with ipsilateral pupillary dilation and
contralateral hemiparesis is classic for an epidural hematoma. Arterial bleeding (often middle meningeal
artery) causes rapid expansion. Diffuse axonal injury (A) typically presents with immediate
unconsciousness. Subdural hematoma (C) often presents gradually in elderly or anticoagulated patients.
Subarachnoid hemorrhage (D) usually presents with sudden severe headache, not lucid interval.
Why Wrong:
A - Diffuse axonal injury causes immediate loss of consciousness without lucid interval.
C - Subdural hematoma typically has a slower onset, especially in non-anticoagulated patients.
D - Subarachnoid hemorrhage from aneurysm presents with sudden headache, not lucid interval.

Q4. A patient with a pelvic fracture from a crush injury is hypotensive. The trauma team applies a
pelvic binder. Despite 2 units of packed red blood cells, the patient remains tachycardic and
hypotensive. Which of the following should be performed next?
A. Angiography with embolization
B. Repeat pelvic X-ray to assess binder placement
C. Open reduction and internal fixation (ORIF) of the pelvis
D. Infusion of recombinant factor VIIa
Correct Answer: A. Angiography with embolization
Rationale: In a hemodynamically unstable patient with a pelvic fracture despite binder and blood,
arterial hemorrhage is likely. Angiography with embolization is the next step for arterial bleeding. Repeat
X-ray (B) delays intervention. ORIF (C) is definitive but not for acute hemorrhage control. Factor VIIa
(D) is not first-line and may increase thrombotic risk.
Why Wrong:
B - Repeating X-ray does not treat ongoing hemorrhage.
C - ORIF is a surgical procedure for stable fractures, not acute hemorrhage control.
D - Recombinant factor VIIa is not indicated for pelvic fracture bleeding without coagulopathy.
