& Answers | High-Yield 100 MCQs with Solutions
1. A 35-year-old male was ejected from a vehicle in a high-speed crash. He is conscious
but confused, has tachycardia, and BP 88/56 mmHg. His pelvis is unstable. Priority
intervention?
A. Apply cervical collar
B. Rapid transport with pelvic stabilization and IV fluids ✅
C. Administer high-flow O₂
D. Full body scan
Rationale: Hypovolemic shock from pelvic fracture; pelvic binder and rapid transport
critical.
2. A 28-year-old female falls 15 feet, complains of neck pain, numbness in legs, unable
to move lower extremities. Spinal precautions applied. Next step?
A. Log-roll supine
B. Maintain airway with in-line immobilization and high-flow O₂ ✅
C. Aggressive IV fluids
D. Straighten legs
Rationale: Protect airway and oxygenation; prevent further spinal damage.
3. Patient with sucking chest wound. First step?
A. Insert OPA
B. Apply occlusive dressing taped 3 sides ✅
C. Begin positive-pressure ventilation
D. Rapid transport
Rationale: Prevent tension pneumothorax.
,4. 45-year-old male blunt abdominal trauma, pale, rigid abdomen, BP 76/48, HR 128.
Most likely condition?
A. Spinal shock
B. Internal hemorrhage with hypovolemic shock ✅
C. Pneumothorax
D. Cardiac tamponade
Rationale: Signs indicate intra-abdominal bleeding; rapid transport needed.
5. Femur fracture, BP 90/60, HR 122. Preferred IV fluid?
A. Dextrose 5%
B. Isotonic crystalloid (NS/LR) ✅
C. Hypotonic saline
D. Packed RBCs
Rationale: Restore volume in hypovolemic shock; avoid hypotonic fluids.
6. 60-year-old male posterior hip dislocation, leg shortened, internally rotated. Next
step?
A. Field reduction
B. Immobilize and transport ✅
C. IV pain meds, allow to walk
D. Apply traction splint
Rationale: ED reduction safer; prevent neurovascular injury.
7. Trapped under debris 30 min, confused, tachycardic, dark urine. Suspect?
A. Compartment syndrome
B. Crush syndrome with rhabdomyolysis and hyperkalemia ✅
C. Hypoglycemia
, D. Heat stroke
Rationale: Muscle injury releases potassium/myoglobin; hospital monitoring needed.
8. Trauma patient: one pupil dilated, BP 150/90, HR 56. Priority?
A. Rapid IV fluids
B. Elevate head 30°, O₂, rapid transport ✅
C. Lumbar puncture
D. Apply head tourniquet
Rationale: Increased ICP (Cushing’s triad); airway support and rapid transport.
9. Severe scalp laceration, direct pressure fails. Next step?
A. Hemostatic/pressure dressing ✅
B. Apply ice
C. Elevate legs
D. Clean with alcohol
Rationale: Scalp bleeds profusely; hemostatic dressing needed.
10. High-voltage electrical injury, conscious, chest discomfort. Immediate assessment?
A. Observe
B. Cardiac rhythm/12-lead ECG ✅
C. Cold compress
D. IV fluids only
Rationale: Risk of arrhythmias; early cardiac monitoring critical.
11. 50-year-old male, blunt chest trauma, absent breath sounds right side, hypotensive,
tachycardic. Most likely condition?
A. Pulmonary embolism
