Trauma Indian Medical PG Practice Questions and MCQs

Question 791: A 50-year old male with significant smoking history presented in the surgical emergency with sudden severe breathlessness. Chest X-ray shows right sided Pneumothorax. The appropriate management requires:

A. Right chest drain of size 8-14 Fr (Correct Answer)
B. Mechanical ventilation
C. Aspiration of air with 16-18 G cannula
D. Oxygen by face mask

Explanation: ***Right chest drain of size 8-14 Fr*** - A **chest drain (thoracostomy tube)** is indicated for spontaneous pneumothorax, especially in symptomatic patients like this one, to allow trapped air to escape and the lung to re-expand. - A **small-bore catheter (8-14 Fr)** is generally preferred for primary spontaneous pneumothorax due to comparable efficacy to large-bore tubes but with less pain and fewer complications. *Mechanical ventilation* - **Mechanical ventilation** is not the primary treatment for pneumothorax; it may be needed if the patient develops respiratory failure despite chest drain insertion or if there's a tension pneumothorax causing hemodynamic instability. - Initiating mechanical ventilation without addressing the underlying pneumothorax can worsen the situation by increasing **intrathoracic pressure**. *Aspiration of air with 16-18 G cannula* - **Needle aspiration** with a 16-18G cannula is typically reserved for initial management of a **stable, small primary spontaneous pneumothorax** (< 2 cm apex-to-cupola distance), or as a temporary measure for tension pneumothorax. - For a symptomatic patient with a significant pneumothorax, a **chest drain** offers more definitive and sustained air removal compared to needle aspiration. *Oxygen by face mask* - Administering **oxygen by face mask** is an supportive measure and it can accelerate resorption of air, but it does not resolve the pneumothorax itself by evacuating the trapped air. - While oxygen therapy is important, it is **insufficient as the sole treatment** for a symptomatic pneumothorax that requires active air removal.

Question 792: Indications for fasciotomy in compartment syndrome include all EXCEPT:

A. Compartment pressure > 30 mm Hg
B. Distal sensory disturbance
C. Palpable distal pulses (Correct Answer)
D. Pain on passive movement of affected muscles

Explanation: ***Palpable distal pulses*** - The presence of **palpable distal pulses is NOT an indication for fasciotomy** and does not rule out compartment syndrome. - **Vascular compromise is a late sign** in compartment syndrome - pulses often remain palpable even with significant nerve and muscle ischemia. - Fasciotomy decisions should be based on **clinical signs** (pain, sensory changes) and **pressure measurements**, not the presence of pulses. - This is the correct answer because it is NOT an indication for the procedure. *Compartment pressure > 30 mm Hg* - **Absolute indication for fasciotomy** when compartment pressure exceeds 30 mmHg, or when the **delta pressure** (diastolic BP minus compartment pressure) is less than 30 mmHg. - This pressure level impairs capillary perfusion and leads to tissue ischemia. *Distal sensory disturbance* - **Early and reliable indication** for fasciotomy showing nerve ischemia. - Paresthesia or numbness in the distribution of nerves running through the affected compartment indicates neurological compromise from elevated intracompartmental pressure. *Pain on passive movement of affected muscles* - **Most sensitive and earliest clinical sign** of compartment syndrome (part of "the 6 P's"). - Pain on passive stretch is typically **out of proportion to the injury** and indicates underlying muscle ischemia. - This is a clear indication for fasciotomy.

Question 793: A 25-year-old man sustains a stab wound to the right chest at the 4th intercostal space, midaxillary line. He is hemodynamically stable with normal breath sounds bilaterally. Chest X-ray shows a small right pneumothorax (15%) and no hemothorax. What is the most appropriate initial management?

A. Chest tube insertion (Correct Answer)
B. Emergency thoracotomy
C. Observation with serial chest X-rays
D. CT scan of the chest

Explanation: ***Chest tube insertion*** - A **chest tube** is indicated for **all pneumothoraces caused by penetrating trauma**, regardless of size, due to the high risk of progression, continued air leak, or occult injuries. - This patient's penetrating mechanism (stab wound to chest) mandates chest tube placement even though he is currently stable with a 15% pneumothorax. - Chest tube provides definitive management and allows monitoring for potential hemothorax development. *Emergency thoracotomy* - **Emergency thoracotomy** is reserved for severe, life-threatening injuries such as unstable patients with massive hemothorax, cardiac tamponade, or ongoing severe hemorrhage. - This patient is **hemodynamically stable** with a small pneumothorax and no hemothorax, which contraindicates the need for an immediate thoracotomy. *Observation with serial chest X-rays* - **Observation** may be appropriate for very small, asymptomatic spontaneous pneumothoraces in non-trauma patients. - Due to the **penetrating trauma mechanism**, observation is inappropriate regardless of the current size (15%), as there is high risk of progression to tension pneumothorax or development of delayed hemothorax. *CT scan of the chest* - A **CT scan** provides more detailed imaging but is not the initial management for an acute pneumothorax caused by penetrating trauma when chest X-ray has already confirmed the diagnosis. - The immediate priority is managing the pneumothorax with chest tube insertion; delaying intervention for CT scan could be detrimental if the pneumothorax progresses.

Question 794: A 35-year-old man presents to the emergency department after a motorcycle accident. He has a blood pressure of 80/50 mmHg, heart rate of 120/min, and is alert but anxious. FAST exam shows free fluid in the pelvis. His hemoglobin is 8.2 g/dL (normal 14-16 g/dL). Which combination of findings best supports the need for immediate surgical intervention?

A. Hemodynamic instability with positive FAST exam (Correct Answer)
B. Low hemoglobin with normal vital signs
C. Free fluid in pelvis with normal blood pressure
D. Motorcycle accident mechanism with stable vitals

Explanation: ***Hemodynamic instability with positive FAST exam*** - The combination of **hypotension** (80/50 mmHg), **tachycardia** (120/min), and a **positive FAST exam** (free fluid in the pelvis) indicates active internal bleeding and hypovolemic shock. - These findings are classic indications for immediate **surgical exploration** to control hemorrhage and stabilize the patient. *Low hemoglobin with normal vital signs* - While a low hemoglobin (8.2 g/dL) indicates blood loss, **normal vital signs** would suggest that the bleeding is not currently life-threatening or that the patient has compensated. - This scenario might warrant further investigation and close monitoring, but not necessarily **immediate surgery**. *Free fluid in pelvis with normal blood pressure* - **Free fluid on FAST exam** suggests internal bleeding, but if the patient's **blood pressure is normal**, they may be hemodynamically stable or compensating. - This situation typically calls for further diagnostic imaging (e.g., CT scan) to quantify the amount of fluid and identify the source of bleeding before deciding on surgical intervention. *Motorcycle accident mechanism with stable vitals* - A **high-energy mechanism** like a motorcycle accident elevates suspicion for significant injuries, but **stable vital signs** imply the patient is not in immediate life-threatening hypovolemic shock. - Close observation and thorough diagnostic workup, including imaging, would be necessary, but **immediate surgery** is not mandated solely by mechanism with stability.

Question 795: 45-year-old construction worker presents after falling from scaffolding. He has multiple injuries: closed head injury with GCS 12, flail chest with respiratory distress, grade 3 splenic laceration with hemoperitoneum, and an open femur fracture. His blood pressure is 85/50 mmHg, heart rate 125/min, and oxygen saturation 88%. The trauma team must prioritize interventions. What is the most appropriate sequence of management?

A. Intubation → splenectomy → external fixation of femur → ICP monitoring
B. Intubation → chest tube → splenectomy → damage control orthopedics (Correct Answer)
C. Chest tube → splenectomy → intubation → neurosurgical intervention
D. Splenectomy → intubation → femur fixation → neurosurgical consultation

Explanation: ***Intubation → chest tube → splenectomy → damage control orthopedics*** - The patient presents with **severe respiratory distress** (O2 sat 88%, flail chest) and a **low GCS (12)**, necessitating immediate **airway protection** and **ventilatory support via intubation**. Following intubation, addressing the **flail chest** and potential **pneumothorax/hemothorax** with a **chest tube** is crucial to improve ventilation and oxygenation. - The patient is **hemodynamically unstable** (BP 85/50, HR 125/min) due to a **grade 3 splenic laceration with hemoperitoneum**, which requires immediate surgical intervention like **splenectomy** to control life-threatening hemorrhage. After stabilizing the life-threatening conditions, the **open femur fracture** should be managed with **damage control orthopedics** (e.g., external fixation) to prevent further blood loss and systemic inflammation, deferring definitive fixation until the patient is stable. *Intubation → splenectomy → external fixation of femur → ICP monitoring* - While **intubation** is correctly prioritized, immediately proceeding to **splenectomy** before addressing the flail chest with a **chest tube** could compromise respiratory status. - **External fixation of the femur** and **ICP monitoring** are important but follow the immediate life-saving procedures for hemorrhage and respiratory compromise. *Chest tube → splenectomy → intubation → neurosurgical intervention* - Prioritizing **chest tube insertion** before **intubation** in a patient with a GCS of 12 and severe respiratory distress (flail chest, O2 sat 88%) is incorrect, as **airway protection** is always the first priority in trauma. - **Neurosurgical intervention** for the closed head injury would typically be considered after initial stabilization of ABCs and hemorrhage control. *Splenectomy → intubation → femur fixation → neurosurgical consultation* - Initiating with **splenectomy** before **intubation** is incorrect, as securing the airway and breathing (ABCs) is paramount in a patient with GCS 12 and respiratory distress. - While **femur fixation** is important, it follows the immediate life-saving interventions for airway, breathing, and circulation.

Question 796: An 18-year-old athlete suffers a severe traumatic brain injury with increased intracranial pressure. He requires decompressive craniectomy. His parents disagree about the extent of surgical intervention - his father wants maximum treatment, while his mother is concerned about quality of life. The patient had previously expressed wishes to 'never be a vegetable.' Evaluate the ethical approach to decision-making.

A. Follow the patient's previously expressed wishes
B. Limit intervention based on mother's quality of life concerns
C. Ethics consultation with family mediation (Correct Answer)
D. Court-ordered guardianship determination

Explanation: **Ethics consultation with family mediation** - An **ethics consultation** can provide a neutral forum to discuss conflicting parental desires and the patient's previously stated wishes, aiming for a consensus. - **Mediation** helps navigate complex ethical dilemmas by ensuring all perspectives are heard, clarified, and weighed against ethical principles like **beneficence**, **non-maleficence**, and **respect for autonomy**. *Follow the patient's previously expressed wishes* - While patient autonomy is crucial, the phrase "never be a vegetable" is a **vague declaration** that lacks the specificity of an **advance directive** and may not apply directly to the current acute situation with potential for recovery. - At 18, the patient is an adult, but the urgency and severity of the injury, combined with parental disagreement, necessitate a more formal process than simply interpreting a casual past statement, especially when the patient's capacity for current decision-making is compromised. *Limit intervention based on mother's quality of life concerns* - Giving preference to one parent's concerns over the other's, or over the patient's complex situation, would be **unethical** and could lead to legal and emotional conflict. - While **quality of life** is an important consideration, it must be balanced with the potential for recovery and other ethical principles, not unilaterally decided by one parent. *Court-ordered guardianship determination* - This is an **extreme measure** typically reserved for situations where basic care decisions cannot be made, or there is suspicion of abuse or severe neglect. - It would be a lengthy legal process, inappropriate for an urgent medical decision, and should only be considered if all other avenues of conflict resolution fail.

Question 797: A patient involved in a Road Traffic Accident (RTA) presents with: - Absent air entry on the left side of the chest. - Tenderness in the left lower chest wall. What is the next step in the Emergency Medicine Room (EMR) management?

A. X-ray (Correct Answer)
B. FAST
C. DPL
D. CT

Explanation: ***X-ray*** - In a **hemodynamically stable** patient with absent air entry and chest wall tenderness post-RTA, a **chest X-ray** is the most appropriate initial imaging in the EMR. - It quickly diagnoses conditions like **pneumothorax**, **hemothorax**, or **rib fractures** and guides management decisions. - **Important**: Clinical assessment for **tension pneumothorax** (hypotension, tracheal deviation, distended neck veins) must be done first. If tension pneumothorax is suspected, **immediate needle decompression** is required without waiting for imaging. - X-ray is **rapidly available** and provides crucial information for trauma management in stable patients. *FAST* - **Focused Assessment with Sonography for Trauma (FAST)** is primarily used to detect **intra-abdominal free fluid** (hemoperitoneum) or pericardial effusion in trauma. - While valuable in RTA evaluation, it is not the primary diagnostic tool for absent air entry in the chest. - FAST has limited sensitivity for **pneumothorax** and does not visualize **rib fractures** in detail. *DPL* - **Diagnostic Peritoneal Lavage (DPL)** is an invasive procedure used to detect **intra-abdominal injury** and hemorrhage. - It has largely been replaced by FAST and CT scans due to its invasive nature and lower specificity. - DPL provides **no information about chest injuries** and is irrelevant for evaluating absent air entry. *CT* - A **CT scan** (chest CT) provides highly detailed imaging and is excellent for diagnosing specific chest injuries. - However, it is **time-consuming**, requires patient transport, and is typically reserved for **stable patients** after initial X-ray assessment. - In the immediate EMR setting, X-ray is preferred for rapid decision-making, with CT used for further evaluation if needed.

Question 798: Mr. Ramu, a 35-year-old male, sustained a straddle injury in a motor vehicle accident and presents to the emergency department with blood at the urethral meatus. What is the next appropriate step in his management?

A. CECT Abdomen
B. FAST
C. Abdomen X-ray
D. Retrograde urethrogram (Correct Answer)

Explanation: ***Retrograde urethrogram*** - **Blood at the urethral meatus** after a straddle injury is highly suggestive of **urethral injury**, and a retrograde urethrogram is the diagnostic test of choice to assess the integrity of the urethra. - This procedure involves injecting contrast into the urethra to visualize any extravasation, strictures, or complete disruptions before attempting catheterization. *CECT Abdomen* - A CECT abdomen is primarily used to assess **solid organ injuries** or **intra-abdominal bleeding**, which is not the primary concern suggested by blood at the urethral meatus. - While broad abdominal trauma may warrant a CECT, it does not directly evaluate urethral integrity. *FAST* - **FAST (Focused Assessment with Sonography for Trauma)** is a rapid ultrasound examination to detect **free fluid (blood)** in the peritoneal or pericardial cavities. - It is used to identify **intra-abdominal or pericardial hemorrhage** and guide resuscitation, but it does not visualize the urethra. *Abdomen X-ray* - An abdomen X-ray can detect **fractures of the pelvis** or foreign bodies, but it does not provide detailed imaging of soft tissues like the urethra. - It would not show urethral extravasation or disruption, making it insufficient for diagnosing urethral injury.

Question 799: A patient with a left hypochondrium contusion presents with systolic blood pressure of 70 mm Hg and pulse rate of 110 bpm. What is the best step in management?

A. Conservative management with observation
B. Chest tube insertion
C. Antibiotic therapy
D. Emergency surgical exploration (Correct Answer)

Explanation: ***Emergency surgical exploration*** - The patient's **hypotension** (BP 70 mmHg) and **tachycardia** (HR 110 bpm) indicate **hemodynamic instability**, suggesting active bleeding, likely from a splenic or liver injury in the context of a left hypochondrium contusion. - While initial resuscitation with IV fluids is started simultaneously, this degree of shock (class III-IV hemorrhage) with a high-risk mechanism typically requires **emergency surgical exploration** to identify and control the source of bleeding. - According to **ATLS protocols**, patients who are non-responders or transient responders to initial resuscitation with ongoing hemodynamic instability are candidates for immediate operative intervention. *Conservative management with observation* - This approach is appropriate only for **hemodynamically stable** patients with solid organ injuries, often with minor extravasation or hematomas that are not actively bleeding. - The patient's severe hypotension and tachycardia preclude conservative management, as it would risk further decompensation and mortality due to ongoing blood loss. *Chest tube insertion* - This procedure is indicated for managing conditions like **pneumothorax** or **hemothorax**, which might present with respiratory distress, decreased breath sounds, and potentially hemodynamic compromise if severe. - While a chest injury could coexist, the primary concern here is profound shock following an abdominal contusion, suggesting intra-abdominal hemorrhage rather than a thoracic injury as the initial priority. *Antibiotic therapy* - **Antibiotic therapy** is important for preventing or treating infections, particularly in cases of bowel perforation or open wounds, but it does not address acute hemodynamic instability from hemorrhage. - Administering antibiotics before surgically addressing the source of bleeding in a hypotensive patient would be a misprioritization and would not stabilize their condition.

Question 800: A patient presents with breathlessness and decreased air entry into the right lung following a road traffic accident (RTA) and is hypotensive. What is the next step in management?

A. Wide bore needle decompression
B. Needle insertion at 5th ICS in mid-axillary line
C. Needle insertion at 2nd ICS in midclavicular line (MCL) (Correct Answer)
D. Fluid resuscitation using wide bore cannula

Explanation: ***Needle insertion at 2nd ICS in midclavicular line (MCL)*** - The combination of **breathlessness**, **decreased air entry**, **hypotension** following trauma indicates a **tension pneumothorax**, which requires immediate decompression. - **Needle decompression** at the **2nd intercostal space (ICS)** in the **midclavicular line (MCL)** is the recommended immediate life-saving procedure to relieve pressure according to **ATLS guidelines**. - This option is the **most complete and precise answer**, specifying both the procedure and the exact anatomical location needed for safe execution. *Wide bore needle decompression* - While this correctly identifies the procedure type (needle decompression with a wide bore needle), it lacks the **critical anatomical specification** needed for clinical application. - In an emergency, knowing **where** to insert the needle is as important as knowing to perform the procedure - **2nd ICS at MCL** is the standard taught location. - This option is incomplete compared to the option that specifies the exact anatomical landmark. *Needle insertion at 5th ICS in mid-axillary line* - The **5th ICS in the mid-axillary line** is the appropriate location for inserting a **chest drain (tube thoracostomy)**, which is a definitive treatment but not the immediate emergency intervention. - For **tension pneumothorax**, immediate **needle decompression at 2nd ICS MCL** must be performed first to relieve life-threatening pressure, followed by chest tube insertion. - Using this location for initial needle decompression is not standard ATLS protocol. *Fluid resuscitation using wide bore cannula* - While **fluid resuscitation** is important for a trauma patient with hypotension, it will not address the primary life-threatening issue of **tension pneumothorax**. - The immediate priority is to relieve the pressure on the heart and lungs, as hypotension in this context is due to **obstructive shock** from impaired venous return and cardiac output. - Fluids alone will not correct the mechanical obstruction caused by the tension pneumothorax.
