1. A 22-year-old male arrives after a motorcycle collision. He is agitated
and keeps trying to sit up. His respiratory rate is 36, pulse is 120, and
blood pressure is 80/60. What is the most likely cause of his shock?
A. Neurogenic shock
B. Obstructive shock
C. Hemorrhagic shock
D. Cardiogenic shock
Answer: C. Hemorrhagic shock
Explanation: In a trauma patient with tachycardia, tachypnea,
hypotension, and altered mental status, hemorrhagic shock is the most
common cause. The mechanism of injury (motorcycle collision)
supports high-energy transfer with potential for significant blood loss.
Neurogenic shock would present with bradycardia and warm
extremities. Obstructive shock (e.g., tension pneumothorax) would
present with distended neck veins and tracheal deviation. Cardiogenic
shock is rare in young patients without preceding chest trauma.

2. A 45-year-old man falls from a height. He opens his eyes to pain,
makes incomprehensible sounds, and withdraws from pain. What is his
Glasgow Coma Scale score?
A. 6
B. 7
C. 8
D. 9
Answer: C. 8
Explanation: Glasgow Coma Scale is calculated by adding the best
scores in three categories: eye opening (E), verbal response (V), and
motor response (M). Eyes open to pain scores 2, incomprehensible
sounds score 2, and withdrawal from pain scores 4. This totals 8. A
score of 8 or less is generally considered a criterion for definitive airway
management.
3. During the primary survey, you note the patient has distended neck
veins, absent breath sounds on the right, and tracheal deviation to the
left. What is the immediate intervention?
A. Chest X-ray
B. Needle decompression
C. Pericardiocentesis
D. Thoracotomy
Answer: B. Needle decompression
Explanation: The classic triad of distended neck veins, absent breath
sounds, and tracheal deviation indicates a tension pneumothorax.
,3|Page
Immediate treatment is needle decompression at the second
intercostal space in the midclavicular line, followed by tube
thoracostomy. Waiting for a chest X-ray risks cardiac arrest.
Pericardiocentesis treats cardiac tamponade, which also has distended
neck veins but presents with bilateral breath sounds.
4. After securing an airway in a patient with severe maxillofacial
trauma, what is the most reliable method to confirm correct
endotracheal tube placement?
A. Chest auscultation
B. Observation of chest rise
C. Continuous end-tidal CO2 capnography
D. Colorimetric CO2 detector
Answer: C. Continuous end-tidal CO2 capnography
Explanation: While all options help confirm tube placement, continuous
waveform capnography is the gold standard as it provides ongoing,
real-time verification and can immediately detect extubation or
malposition. Chest auscultation and observation can be misleading in
trauma. Colorimetric devices provide qualitative data and can give false
negatives in low perfusion states.
5. A patient with a pelvic fracture has a blood pressure of 70/40 and
heart rate of 140 after 2 L of crystalloid. What is the next step in
management?
A. Continue crystalloid resuscitation
B. Initiate massive transfusion protocol
, 4|Page
C. Apply a pelvic binder
D. Both B and C
Answer: D. Both B and C
Explanation: This patient is in Class IV hemorrhagic shock and is not
responding to initial crystalloid boluses, indicating the need for
balanced blood product resuscitation per the massive transfusion
protocol. Mechanical stabilization with a pelvic binder reduces pelvic
volume, tamponades bleeding, and stabilizes clots. Both interventions
should occur simultaneously.
6. A 30-year-old male has a stab wound to the anterior chest. His heart
rate is 115, blood pressure is 90/60, and neck veins are distended.
Heart sounds are muffled. What is the diagnosis?
A. Tension pneumothorax
B. Cardiac tamponade
C. Massive hemothorax
D. Air embolism
Answer: B. Cardiac tamponade
Explanation: Beck's triad (hypotension, muffled heart sounds, distended
neck veins) in the setting of a penetrating chest injury is
pathognomonic for cardiac tamponade. Immediate intervention
includes pericardial window or thoracotomy. Tension pneumothorax
would have absent breath sounds and tracheal deviation.
