Q1.
During the primary survey, a patient with blunt thoracic trauma presents with absent
breath sounds on the left and distended neck veins. Immediate decompression is
performed. Which finding indicates that needle decompression has been effective?
A. Immediate return of breath sounds B. A rush of air upon needle insertion
C. Decrease in heart rate and improvement D. Subcutaneous emphysema around the
in blood pressure insertion site
Correct: B - A rush of air upon needle insertion
Rationale:A rush of air confirms entry into the pleural space and successful decompression
of a tension pneumothorax. While clinical improvement may follow, the immediate
confirmation is the rush of air. Subcutaneous emphysema can occur with incorrect placement.
Return of breath sounds may take time.
Q2.
A patient with a femur fracture and pelvic fracture arrives with a heart rate of 120 bpm and
blood pressure 90/60 mm Hg. After 2 liters of warmed crystalloid, blood pressure remains
85/55 mm Hg. Which next step is most appropriate?
A. Administer another 2 liters of crystalloid B. Transfuse packed red blood cells and
rapidly plasma in a 1:1 ratio
C. Apply a pelvic binder and re-image the D. Start a norepinephrine infusion to support
pelvis blood pressure
Correct: B - Transfuse packed red blood cells and plasma in a 1:1 ratio
Rationale:The patient is a non-responder to initial crystalloid, indicating ongoing hemorrhage.
ATLS guidelines recommend early blood product transfusion (1:1:1) for hemorrhagic shock.
Further crystalloid may worsen acidosis and coagulopathy. A pelvic binder may already be
indicated but does not address the need for blood. Vasopressors are not first-line in
hemorrhagic shock.
Q3.
In the assessment of a patient with a penetrating neck injury, which finding mandates
immediate surgical exploration rather than further diagnostic workup?

Surgery Emergency Medicine Graduate / Postgraduate Residency/fellowship
A. Subcutaneous emphysema B. Hoarseness
C. Expanding hematoma with airway D. Dysphagia
compromise
Correct: C - Expanding hematoma with airway compromise
Rationale:An expanding hematoma causing airway compromise is a hard sign of vascular
injury requiring immediate operative intervention. Subcutaneous emphysema, hoarseness,
and dysphagia are soft signs that may prompt further evaluation but do not mandate
immediate surgery.
Q4.
A victim of a blast injury presents with tympanic membrane rupture and no external signs.
Which type of blast injury is this?
A. Primary blast injury B. Secondary blast injury
C. Tertiary blast injury D. Quaternary blast injury
Correct: A - Primary blast injury
Rationale:Primary blast injury results from the blast wave itself, typically affecting air-filled
organs like the ears, lungs, and GI tract. Tympanic membrane rupture is a classic primary
injury. Secondary injuries are from flying debris, tertiary from displacement, and quaternary
from burns or inhalation.
Q5.
A patient with a severe traumatic brain injury (TBI) is intubated and being ventilated.
Which ventilation strategy is most appropriate to minimize secondary brain injury?
A. Maintain PaCO2 at 40 mm Hg B. Hyperventilate to PaCO2 of 25 mm Hg
C. Maintain PaCO2 at 30 mm Hg D. Maintain PaCO2 at 50 mm Hg
Correct: A - Maintain PaCO2 at 40 mm Hg
Rationale:ATLS recommends maintaining normocapnia (PaCO2 35-40 mm Hg) in TBI
patients to avoid cerebral vasoconstriction from hypocapnia, which can worsen ischemia.
Prophylactic hyperventilation is no longer recommended. Hypocapnia (PaCO2 <30) should
only be used transiently for acute herniation. Hypercapnia (PaCO2 >45) can increase ICP.
Q6.
In a patient with a suspected spinal cord injury, which finding indicates neurogenic shock
rather than spinal shock?
