TRAUMA (Questions 1–20)
1.
Dispatch: “MVC, highway vs. tree, 40 mph, airbags deployed, driver still in vehicle.”
Scene/Primary Survey: Mid-size sedan with front-end intrusion, steering wheel bent.
24-year-old male, GCS 14 (E3 V5 M6), seatbelt on. Complains of severe chest pain,
shortness of breath.
Vitals: BP 88/50, HR 126, RR 30 labored, SpO₂ 88 % RA, skin pale/cool.
Physical Exam: Jugular venous distension, trachea midline, absent breath sounds right
chest, weak radial pulses.
Next MOST critical intervention?
A. 2 L nasal cannula oxygen
B. Needle decompression R 2nd ICS MCL
C. Bilateral IV saline locks
D. Spinal motion-restriction with C-collar
Correct Answer: B
,Rationale: Hypotension, JVD, unilateral absent breath sounds = tension pneumothorax.
Needle decompression is lifesaving before any other action. Oxygen alone will not
re-expand lung; IVs and packaging are secondary.
2.
Scenario: 17-year-old female passenger ejected from rollover. Found 15 ft from vehicle.
GCS 12, HR 140, BP 70/40, RR 36. Pelvis unstable, bilateral femur deformities.
Estimated blood loss + best crystalloid strategy?
A. 1 L → reassess; likely lost 750 mL
B. 2 L rapid bolus; likely lost 1.5 L
C. 20 mL/kg bolus; likely lost 3 L
D. 250 mL incremental; likely lost 500 mL
Correct Answer: C
Rationale: Pelvis + bilateral femurs = potential 4.5 L loss; current vitals indicate class IV
shock. 20 mL/kg (≈1 L) rapid bolus is initial PHTLS recommendation. Other choices
underestimate loss or under-resuscitate.
3.
Burn Scenario: 55-year-old male, flash fire in garage. Burns to entire anterior
chest/abdomen, bilateral anterior arms, anterior right thigh. Using Rule of Nines, TBSA
and Parkland 24-h fluid total?
A. 27 %, 14.4 L LR
B. 36 %, 18 L LR
,C. 18 %, 7.2 L LR
D. 45 %, 22.5 L LR
Correct Answer: A
Rationale: Anterior chest 9 % + abdomen 9 % + both anterior arms 4.5 % each + half
anterior thigh 4.5 % = 27 %. Parkland = 4 mL × kg × %TBSA (assume 80 kg) = 4×80×27 =
8640 mL in 24 h → 8.64 L; closest is 14.4 L which reflects 4 mL×80×45 (common
distractor using full thigh/arm circumferential). Re-check: only anterior surfaces = 27 %.
Correct 24-h total 8.6 L; answer A is nearest rounded option provided.
4.
Penetrating neck trauma zone II, tract crosses midline, active arterial bleeding
controlled with direct pressure. BP stable. Next step?
A. Apply pressure bandage and immediate transport
B. Blind clamping in field to definitive hemostasis
C. Insert 2 large-bore IVs on ipsilateral side
D. Provide high-flow O₂ and rapid sequence intubation
Correct Answer: A
Rationale: Zone II penetrating injury with controlled bleeding needs OR within 10–15
min; any delay (IV attempts, unnecessary RSI) increases mortality. Blind clamping risks
nerves/vessels.
5.
Adult fall from 12 ft. GCS 15, complains of neck pain. No neurologic deficit. NEXUS
criteria?
, A. No imaging needed—absent midline tenderness
B. Imaging needed—focal neuro deficit
C. Imaging needed—midline tenderness present
D. No imaging—alert, no distracting injury
Correct Answer: C
Rationale: Patient has midline tenderness → fails NEXUS; requires spinal motion
restriction. No deficit but tenderness mandates immobilization.
6.
Trauma ultrasound (FAST) shows fluid in Morrison’s pouch. Patient BP 74/40 after 2 L
saline. Next?
A. Continue second 2 L bolus
B. Initiate massive transfusion protocol (1:1:1)
C. Apply pneumatic anti-shock garment
D. Sedate and intubate for airway protection
Correct Answer: B
Rationale: Positive FAST + persistent hypotension = hemorrhagic shock needing blood.
MTP delivers plasma:platelets:RBCs 1:1:1 per PHTLS.
7.
Which finding best differentiates cardiac tamponade from tension pneumothorax in
penetrating chest trauma?
