Free traumatology MCQ exam model for clinical students

Explanation:

• Severe head injury → Correct because GCS ≤ 8 indicates severe traumatic brain injury.

• Mild head injury → Incorrect because GCS is 13–15.

• Moderate head injury → Incorrect because GCS is 9–12.

• Brain death → Incorrect because it is a clinical diagnosis.

• Vegetative state → Incorrect because it is a chronic condition.

Explanation:

• Tibial shaft fracture → Correct because direct bumper injuries commonly fracture tibia.

• Clavicle fracture → Incorrect because it occurs with falls.

• Femoral shaft fracture → Incorrect because it requires high-energy trauma but is less common.

• Pelvic fracture → Incorrect because it is less frequent.

• Vertebral fracture → Incorrect because it is less common.

Explanation:

• Hemorrhage → Correct because uncontrolled bleeding is the leading preventable cause of death.

• Head injury → Incorrect because many are non-preventable.

• Sepsis → Incorrect because it is a late complication.

• Fat embolism → Incorrect because it is uncommon.

• Renal failure → Incorrect because it is a late complication.

Explanation:

• Urine output → Correct because it reflects end-organ perfusion.

• Blood pressure → Incorrect because it may remain normal initially.

• Heart rate → Incorrect because it is nonspecific.

• Respiratory rate → Incorrect because it reflects metabolic acidosis.

• Capillary refill → Incorrect because it is subjective.

Explanation:

• Airway with cervical spine protection → Correct because airway obstruction is immediately life-threatening.

• Control of bleeding → Incorrect because it follows airway and breathing.

• Assessment of disability → Incorrect because it comes later in primary survey.

• Exposure of patient → Incorrect because it is done after ABCs.

• Secondary survey → Incorrect because it is performed after stabilization.

Explanation:

• Hypovolemic shock → Correct because blood loss is common in trauma.

• Cardiogenic shock → Incorrect because it is less common.

• Neurogenic shock → Incorrect because it occurs in spinal injuries only.

• Septic shock → Incorrect because it is a late complication.

• Anaphylactic shock → Incorrect because it is rare.

Explanation:

• Injuries caused by trauma → Correct because traumatology focuses on acute injuries due to external forces.

• Chronic degenerative diseases → Incorrect because these are orthopedic/medical conditions.

• Congenital anomalies → Incorrect because they are present at birth.

• Infectious diseases → Incorrect because these are managed by medicine/surgery.

• Neoplastic conditions → Incorrect because these are tumors.

Explanation:

• Compartment syndrome → Incorrect because it is serious but less common.

• Infection → Incorrect because it is common in open fractures only.

• Non-union → Incorrect because it is a late complication.

• Malunion → Incorrect because it relates to healing.

Explanation:

• Ultrasound FAST → Correct because it rapidly detects internal bleeding at bedside.

• MRI → Incorrect because it is time-consuming.

• CT scan whole body → Incorrect because it is done after stabilization.

• Plain X-rays only → Incorrect because they are limited.

• Angiography → Incorrect because it is for specific indications.

Explanation:

• Rapid assessment and life-saving intervention → Correct because trauma care prioritizes survival.

• Definitive surgical repair → Incorrect because it follows stabilization.

• Pain control → Incorrect because it is supportive.

• Cosmetic outcome → Incorrect because it is secondary.

• Early rehabilitation → Incorrect because it is a later phase.
