Section 1: Hemorrhagic Shock & Resuscitation
1. What is the first sign of hypovolemic shock in a trauma patient?
o A) Bradycardia
o B) Hypertension
o C) Tachycardia
o D) Altered mental status
Answer: Early shock is often signaled by anxiety, restlessness, or confusion due to
decreased cerebral perfusion.
2. A patient with a class III hemorrhage has lost approximately what percentage of blood
volume?
o A) 15%
o B) 15-30%
o C) 30-40%
o D) >40%
*Answer: Class III is 30-40% loss (approx. 1500-2000 mL in adult), marked by
significant tachycardia, tachypnea, and decreased BP.*
3. What is the primary goal of permissive hypotension in the resuscitation of a
penetrating trauma patient?
o A) To normalize blood pressure immediately
o B) To minimize clot disruption and ongoing hemorrhage until surgical control
o C) To improve renal perfusion
, o D) To prevent vasopressor use
*Answer: Permissive hypotension aims to maintain a systolic BP low enough to
avoid destabilizing clots (often ~80-90 mmHg SBP) until definitive control.*
4. Which IV fluid is preferred for the initial resuscitation of a trauma patient in
hemorrhagic shock?
o A) 0.45% Normal Saline
o B) Lactated Ringer's
o C) 5% Dextrose in Water
o D) Hextend
Answer: Balanced crystalloids like Lactated Ringer's are preferred over normal
saline to avoid hyperchloremic acidosis.
5. The "lethal triad" of trauma consists of:
o A) Hypotension, Hypoxia, Hyperthermia
o B) Acidosis, Hypothermia, Coagulopathy
o C) Anemia, Hypoglycemia, Infection
o D) Hypokalemia, Alkalosis, Hypocalcemia
Answer: Acidosis, hypothermia, and coagulopathy are inter-related and self-
perpetuating conditions that dramatically increase mortality.
Section 2: Thoracic Trauma
6. What is the definitive management for a tension pneumothorax?
o A) Needle decompression followed by chest tube thoracostomy
o B) Immediate endotracheal intubation
o C) High-flow oxygen and observation
o D) Rapid transport to the OR
Answer: Needle decompression is an immediate life-saving intervention, but must
be followed by definitive chest tube placement.
7. Beck's triad (hypotension, JVD, muffled heart sounds) is indicative of:
o A) Pulmonary Contusion
o B) Tension Pneumothorax
, o C) Cardiac Tamponade
o D) Aortic Disruption
Answer: Beck's triad is the classic presentation for cardiac tamponade, though it
is often incomplete in trauma.
8. A patient with a flail chest will demonstrate what finding on physical exam?
o A) Tracheal deviation
o B) Paradoxical chest wall movement
o C) Hyper-resonance to percussion
o D) Absent breath sounds unilaterally
Answer: Flail chest is defined by two or more fractures in two or more adjacent
ribs, creating a segment that moves paradoxically (inward on inspiration).
9. The most common immediate life-threatening injury in blunt thoracic trauma is:
o A) Aortic transection
o B) Myocardial contusion
o C) Pulmonary contusion
o D) Tension pneumothorax
Answer: While all are serious, tension pneumothorax requires immediate
recognition and intervention to prevent death.
10. Which of the following is NOT an indication for a thoracotomy in the ED?
o A) Loss of vital signs in the ED after penetrating trauma
o B) Cardiac tamponade from penetrating trauma
o C) Massive air leak from a chest tube
o D) Unilateral hemothorax of 500 mL
*Answer: A 500 mL hemothorax is manageable with a chest tube alone. Massive
ongoing hemorrhage (>1500 mL initial output or >200 mL/hr) is an indication.*
Section 3: Abdominal & Pelvic Trauma
11. The most reliable physical exam finding in a patient with significant blunt abdominal
trauma is:
, o A) Presence of bruising
o B) Abdominal distention
o C) Rebound tenderness
o D) Absent bowel sounds
Answer: Distention suggests significant intra-abdominal hemorrhage. Other signs
are unreliable in trauma.
12. FAST exam (Focused Assessment with Sonography in Trauma) is most accurate for
detecting:
o A) Hollow viscus injury
o B) Retroperitoneal hematoma
o C) Free intraperitoneal fluid (blood)
o D) Diaphragmatic rupture
Answer: FAST is highly specific for free fluid (≥250mL) but poor for solid organ or
hollow viscus injury without fluid.
13. A positive "seat belt sign" on the abdomen increases suspicion for what specific
injury?
o A) Pancreatic transection
o B) Mesenteric tear or small bowel injury
o C) Splenic laceration
o D) Liver laceration
Answer: The deceleration force of a seat belt can cause shearing of the mesentery
or bowel against the fixed spine.
14. The initial management for an unstable patient with a suspected pelvic fracture is:
o A) Log roll and palpate the spine
o B) Application of a pelvic binder or sheet
o C) Immediate CT scan
o D) Diagnostic Peritoneal Lavage (DPL)
Answer: A pelvic binder reduces pelvic volume, stabilizes fractures, and can
tamponade venous bleeding.
