TRAUMA (Questions 1–25)
1.
Dispatch: “High-speed MVC, vehicle vs. tree, 60 mph, driver trapped, airbags deployed.”
Scene: Significant front-end intrusion, steering wheel deformed. 24-year-old male,
seat-belted, GCS 14 (E3 V5 M6). Complains of severe chest pain and shortness of
breath.
Vitals: BP 84/50, HR 130, RR 32 labored, SpO₂ 86 % RA.
Assessment: JVD, trachea midline, absent breath sounds right chest, weak radial
pulses.
Next MOST critical intervention?
A. 2 L nasal cannula O₂
B. Needle decompression R 2nd ICS MCL
C. Bilateral 18-gauge IVs with saline locks
D. Spinal motion-restriction with C-collar
,Correct Answer: B
Rationale: Hypotension, JVD, unilateral absent breath sounds = tension pneumothorax.
Needle decompression is life-saving per PHTLS. O₂ alone will not re-expand lung; IVs
and packaging are secondary.
2.
Same patient post-needle decompression: RR 28, SpO₂ 94 % NRB, BP 90/60. Next step
in hemorrhage control?
A. Administer 2 L saline bolus
B. Apply direct pressure to chest wall
C. Initiate massive transfusion protocol (1:1:1)
D. Digital occlusion of visible vessel
Correct Answer: C
Rationale: Persistent hypotension after airway/ventilation correction indicates
hemorrhagic shock; blood products (MTP) are indicated per PHTLS. Crystalloid worsens
coagulopathy.
3.
Dispatch: “Industrial explosion, flash fire, multiple victims.”
Patient: 35-year-old male, 80 kg. Full-thickness burns to entire anterior trunk and both
anterior arms. Using Rule of Nines, TBSA and Parkland 24-h fluid total?
A. 18 % → 5,760 mL
B. 27 % → 8,640 mL
,C. 36 % → 11,520 mL
D. 45 % → 14,400 mL
Correct Answer: B
Rationale: Anterior trunk 18 % + both anterior arms 9 % = 27 %. Parkland 4 mL × kg ×
%TBSA = 4 × 80 × 27 = 8,640 mL.
4.
Burn patient: HR 120, BP 70/40 after 1 L LR. Which finding best differentiates burn
shock from hemorrhagic shock?
A. Decreased urine output
B. Metabolic acidosis
C. Increased capillary permeability with intracellular Na⁺ accumulation
D. Normal lactate
Correct Answer: C
Rationale: Burn shock is complex—plasma leaks into interstitium and cells; Na⁺-K⁺
pump dysfunction contributes to fluid sequestration, unlike pure blood loss.
5.
Pediatric trauma: 6-year-old (22 kg) falls from 12 ft. GCS 12, HR 170, BP 70/40, RR 40.
Estimated blood loss?
A. 200 mL
B. 300 mL
, C. 450 mL
D. 600 mL
Correct Answer: C
Rationale: Pediatric blood volume ≈ 80 mL/kg → 1,760 mL. Class III shock (30–40 %) ≈
450 mL.
6.
Same child, fluid-refractory hypotensive bradycardia (HR 50). Epinephrine dose?
A. 0.01 mg/kg IV (=0.22 mg)
B. 0.1 mg/kg IV (=2.2 mg)
C. 0.5 mg IM
D. 1 mg IO
Correct Answer: A
Rationale: Pediatric bradycardia unresponsive to ventilation/oxygenation: epinephrine
0.01 mg/kg IV/IO (0.1 mL/kg 1:10,000) q3–5 min.
7.
TBI: 19-year-old helmeted motorcyclist, GCS 10 (E2 V3 M5), BP 150/90, HR 50, irregular
respirations. This pattern represents:
A. Neurogenic shock
B. Cushing response from ↑ ICP
C. Spinal cord transection
