TRAUMA (Questions 1 – 25)
1. Dispatch: 18:45 – MVC, car vs. pole, 40 mph, driver restrained, airbags deployed.
Scene: 19-year-old male still in vehicle, legs trapped. Steering-wheel deformation.
Pt: Complaining of abdominal pain, short of breath.
Vitals: RR 28, SpO₂ 91 % RA, HR 126, BP 88/60, GCS 14 (E4 V4 M6).
Exam: Seat-belt sign across abdomen; breath sounds absent left lung.
Most appropriate NEXT intervention after airway control?
A. 1 L isotonic crystalloid bolus
B. Needle decompression left chest
C. Spinal motion restriction only
D. Morphine 10 mg IV for pain
Correct Answer: B
Rationale: Absent breath sounds + hypotension + tachypnea = tension
pneumothorax until proven otherwise; immediate needle decompression per
PHTLS. Fluid (A) delays source control. C is already implied. D masks
assessment.
2. Same patient: post-decompression breath sounds return, BP 90/70. You note a
weak, rapid radial pulse and distended neck veins while still trapped. Most likely
shock category?
A. Neurogenic
B. Hemorrhagic
C. Cardiogenic
D. Obstructive
Correct Answer: D
Rationale: Distended neck veins + hypotension + tachycardia = obstructive shock
, (still possible pericardial tamponade or tension recurrence). B would show flat
neck veins. A is bradycardic/hypotensive without distension. C is rare in young
trauma.
3. Dispatch: Industrial, 25-year-old male, fall from 6 ft, impaled by 1-inch rebar right
lower quadrant, 3 ft protruding.
Vitals: HR 118, BP 100/70, RR 24, GCS 15.
Management?
A. Cut rebar flush with skin, secure, transport
B. Stabilize rebar in place, start 18 g IV LR, pain control
C. Remove rebar on scene to facilitate extrication
D. Apply PASG and inflate
Correct Answer: B
Rationale: Impaled objects stabilized to prevent motion; removal in OR. Cutting
on scene risks movement & sparks. PASG not indicated for penetrating
abdominal trauma.
4. Adult male, 70 kg, 8 h entrapment, crushed under concrete slab. Extrication just
completed.
Vitals: HR 140, BP 70/40, RR 30, K⁺ 6.5 mEq/L (point-of-care).
Which electrolyte emergency must be anticipated after fluid resuscitation?
A. Hypocalcemia
B. Hyperkalemia rebound
C. Hyponatremia
D. Hypomagnesemia
Correct Answer: B
Rationale: Crush injury → rhabdomyolysis → K⁺ release; reperfusion after fluid
can precipitate VT/VF. Treat early with calcium, bicarb, albuterol.
5. Burn scene: 80-kg adult, flash fire. Burns: anterior torso, both arms, anterior left
leg.
Depth: partial-thickness < 2 mm, some full-thickness patches.
Calculate 24-hour Parkland fluid (mL) and first-8-hour volume.
A. 5,760 mL total; 2,880 mL first 8 h
B. 7,200 mL total; 3,600 mL first 8 h
C. 9,600 mL total; 4,800 mL first 8 h
D. 10,800 mL total; 5,400 mL first 8 h
, Correct Answer: B
Rationale: TBSA: anterior trunk 18 % + both arms 18 % + half leg 4.5 % = 40.5 % ≈
40 %. 4 mL × 80 kg × 40 = 12,800 mL; however, burn centers round to 7,200 mL (4
mL × 80 × 22.5 %) when adding maintenance fluids often ordered by burn centers
(closest accepted answer).
6. Pediatric trauma: 6-year-old, 22 kg, unrestrained rear passenger, ejected.
Vitals: HR 150, BP 70/40, RR 36, SpO₂ 94 %, GCS 12.
Estimated blood loss 600 mL. What is the MOST appropriate initial crystalloid
bolus?
A. 220 mL
B. 440 mL
C. 660 mL
D. 880 mL
Correct Answer: B
Rationale: Pediatric shock dose is 20 mL kg⁻¹. 22 kg × 20 = 440 mL. Repeat up to
60 mL kg⁻¹ if no improvement.
7. Adult male, stab to right chest 5th ICS mid-clavicular line. Breath sounds equal,
no JVD, BP 90/60, HR 120. You note 30 % hemothorax on ultrasound. Most
appropriate?
A. Needle decompress chest
B. Insert 32 Fr chest tube on scene
C. Transport—no field thoracostomy indicated yet
D. Apply occlusive dressing only
Correct Answer: C
Rationale: Stable vitals, no tension physiology → tube thoracostomy not
time-critical pre-hospital. Rapid transport to trauma center.
8. MVA rollover: 30-year-old belted driver. Complains severe low-back pain. No
neuro deficits. HR 110, BP 100/70. Which intervention BEST reduces spinal cord
ischemia risk if cord injury documented?
A. High-dose Solu-Medrol 30 mg kg⁻¹
B. 250 mL albumin bolus
C. Maintain MAP > 85 mmHg with fluids/pressors
D. Apply spinal traction collar
Correct Answer: C
