TRAUMA (Questions 1–20)
1. 0430 hrs. EMS dispatched to a single-vehicle MVC, car vs. tree. Scene is 12 min away
on a rural road; extrication already in progress by fire.
Patient: 22-year-old male, restrained driver. Interior intrusion noted on driver-side door.
Primary survey: A- patent with cervical collar in place; B- RR 24, shallow, audible gurgle;
C- HR 118, BP 88/60, skin pale/cool; D- GCS 14 (E4 V4 M6), left pupil 5 mm and
sluggish; E- FAST exam shows free fluid RUQ.
Pulse ox 89 % on 6 L NRB.
Next most appropriate intervention?
A. Infuse 2 L warmed normal saline wide open
B. Perform on-scene endotracheal intubation
C. Apply direct pressure to obvious extremity laceration
D. Initiate immediate transport to Level-I trauma center
Correct Answer: D
Rationale: Patient is hypotensive (MAP 65) with free fluid on FAST—suspicious for
intra-abdominal hemorrhage. Per PHTLS, “load-and-go” for penetrating torso trauma or
,hemodynamic instability. Airway is patent; intubation can be en-route if needed.
Crystalloid bolus delays definitive hemorrhage control.
2. You are treating a 34-year-old female ejected from a motorcycle at 45 mph. Helmet
remained on.
Vital signs: HR 124, BP 94/56, RR 28, SpO₂ 90 %, GCS 12 (E3 V4 M5).
Breath sounds absent on left; trachea midline; neck veins flat.
Most immediate cause of hypoxia?
A. Tension pneumothorax
B. Massive hemothorax
C. Simple pneumothorax
D. Pulmonary contusion
Correct Answer: C
Rationale: Absent breath sounds without tracheal deviation or JVD indicates simple
pneumothorax. Tension would show deviation and hypotension; massive hemothorax
would present with shock and dullness to percussion. Immediate needle
decompression is not yet indicated; high-flow O₂ and rapid transport are priorities.
3. A 6-year-old is struck by an SUV, thrown 15 ft.
Primary survey: GCS 7, RR 6, HR 52, BP 140/70, irregular respirations.
Highest priority?
,A. Hyperventilate with BVM at 30 breaths/min
B. Secure airway with appropriately sized ETT
C. Apply spinal motion-restriction device
D. Establish bilateral 18-gauge IVs
Correct Answer: B
Rationale: GCS ≤8 mandates airway control. Bradypnea and irregular pattern suggest
impending respiratory arrest; airway comes first. Over-ventilation risks ↑ ICP; goal 20
breaths/min post-intubation. Cervical collar already applied by crew.
4. Which finding best differentiates neurogenic from hypovolemic shock in a trauma
patient?
A. Heart rate
B. Skin color
C. Pulse pressure
D. Capillary refill
Correct Answer: A
Rationale: Neurogenic shock classically presents warm & well-perfused with
bradycardia below T1; hypovolemic shock shows tachycardia and cool skin. Pulse
pressure narrows in both.
5. Adult male burned in garage fire: partial-thickness burns to entire anterior
chest/abdomen, both anterior arms, and genitalia.
, Estimate total BSA burned.
A. 18 %
B. 27 %
C. 36 %
D. 45 %
Correct Answer: B
Rationale: Rule of Nines—anterior trunk 18 %, each arm 4.5 % (×2 = 9 %), genitalia 1 % →
total 28 % (closest 27 %).
6. 18-year-old shot in right lower chest at close range with 9 mm.
Vital signs: HR 110, BP 100/70, RR 26, SpO₂ 94 %.
FAST negative; no exit wound.
Best field treatment?
A. Apply occlusive dressing over entrance
B. Place patient in left lateral recumbent position
C. Transport supine to Level-I trauma center
D. Insert 32 Fr chest tube on scene
Correct Answer: C
