1. Which of the following is the most common mechanism of injury in geriatric trauma patients?
A) Motor vehicle collisions
B) Falls
C) Penetrating injuries
D) Burns
Correct Answer: B
Explanation: Falls are the most common mechanism in geriatric trauma due to age-related
changes like decreased balance, vision, and strength.
2. Hypothermia in a trauma patient is most concerning because it:
A) Increases metabolic demand
B) Worsens coagulopathy
C) Improves oxygen delivery
D) Decreases infection risk
Correct Answer: B
Explanation: Hypothermia impairs platelet function and clotting factor activity, worsening
coagulopathy and increasing mortality.
3. The lethal triad of trauma consists of:
A) Hypoxia, hypotension, hypoglycemia
B) Acidosis, hypothermia, coagulopathy
,C) Tachycardia, tachypnea, hypotension
D) Sepsis, anemia, hypovolemia
Correct Answer: B
Explanation: Acidosis, hypothermia, and coagulopathy create a vicious cycle worsening
outcomes in major trauma.
4. Which of the following is an early sign of increased intracranial pressure (ICP)?
A) Bradycardia with widened pulse pressure
B) Decerebrate posturing
C) Altered level of consciousness
D) Fixed and dilated pupils
Correct Answer: C
Explanation: Altered LOC is often the earliest sign of rising ICP; Cushing’s triad (bradycardia,
hypertension, irregular breathing) occurs later.
5. When caring for a patient with a suspected spinal cord injury, the priority is:
A) Logrolling every 2 hours
B) Maintaining spinal motion restriction
C) Administering high-dose steroids
D) Placing in Trendelenburg position
Correct Answer: B
Explanation: Prevent secondary injury by immobilizing the spine until injury is ruled out.
6. What is the primary goal of damage control resuscitation?
A) Normalize all lab values
, B) Restore tissue perfusion while minimizing bleeding
C) Achieve a systolic BP > 120 mmHg
D) Immediate definitive airway control
Correct Answer: B
Explanation: Permissive hypotension and balanced transfusion prevent exacerbation of bleeding.
7. Which crystalloid is most recommended for initial resuscitation in hemorrhagic shock?
A) Dextrose 5% in water
B) Lactated Ringer’s
C) Normal saline
D) 3% saline
Correct Answer: B
Explanation: Lactated Ringer’s is preferred over normal saline to avoid hyperchloremic
metabolic acidosis.
8. Massive transfusion protocol is typically activated after transfusion of how many units of
PRBCs in 24 hours?
A) 2 units
B) 5 units
C) 10 units
D) 20 units
Correct Answer: C
Explanation: Massive transfusion is often defined as >10 units PRBCs in 24 hours, or 4 units in 1
hour.
