Explanation: In cases of suspected carbon monoxide poisoning, administering 100% oxygen helps to rapidly reduce carboxyhemoglobin levels. In severe cases, hyperbaric oxygen therapy may be indicated.

 

Question: What is the significance of a 'seat belt sign' in trauma patients?

Answer: It indicates a higher risk of internal injuries, especially to the abdomen.

Explanation: The presence of a seat belt sign, which is bruising or abrasion across the abdomen from a seat belt, is a red flag for possible internal organ injury and warrants thorough investigation.

Question: In a trauma patient with maxillofacial injuries, what is the primary concern?

Answer: Airway compromise.

Explanation: Maxillofacial injuries can lead to significant swelling, bleeding, or bone displacement, all of which can obstruct the airway. Ensuring airway patency is the primary concern.

 

Question: What are the indications for a chest tube insertion in trauma?

Answer: Pneumothorax, hemothorax, or hemopneumothorax.

Explanation: A chest tube is indicated in cases of pneumothorax (air in the chest cavity), hemothorax (blood in the chest cavity), or hemopneumothorax (combination of air and blood) to evacuate the contents and allow lung re-expansion.

 

Question: When is permissive hypotension considered in the management of a trauma patient?

Answer: In cases of uncontrolled hemorrhage, particularly in penetrating trauma.

Explanation: Permissive hypotension involves allowing a lower than normal blood pressure until major bleeding can be controlled. This strategy is used to minimize blood loss and is particularly considered in penetrating trauma.

 

Question : What is the key factor in determining the need for transfer to a higher level of care in trauma patients?

- Answer: The severity of injuries and the capabilities of the treating facility.

- Explanation: The decision to transfer a trauma patient is based on the severity and complexity of their injuries and the level of care that the current facility can provide. If the patient's needs exceed the facility's capabilities, transfer to a higher-level trauma center is warranted.

 

Question: In ATLS, what is the role of 'secondary survey'?

Answer: A thorough, head-to-toe evaluation of the trauma patient after life-threatening injuries have been addressed.

Explanation: The secondary survey is a systematic assessment of the entire body to identify all injuries. It's performed after the primary survey and resuscitation, ensuring no injuries are missed.

Question: What is the first-line treatment for an unstable patient with a pelvic fracture?

Answer: Application of a pelvic binder or sheet to stabilize the pelvis and reduce hemorrhage.

Explanation: Pelvic binders or circumferential sheets are used to stabilize pelvic fractures and reduce the potential for massive hemorrhage by closing the pelvic volume.

 

Question: How is a traumatic cardiac arrest different in management compared to a medical cardiac arrest?

Answer: Traumatic cardiac arrest management focuses more on reversing the underlying causes like hypovolemia, tension pneumothorax, or cardiac tamponade.

Explanation: In traumatic cardiac arrest, the priority is to identify and treat reversible causes such as massive hemorrhage, tension pneumothorax, and cardiac tamponade, in addition to standard resuscitation measures.

 

 

 

Question: What is the primary indication for intubation in a burn patient?

Answer: Suspected inhalation injury, especially with signs of airway edema or burns inside the mouth.

Explanation: Early intubation is indicated in burn patients with signs of inhalation injury, as airway edema can rapidly progress and lead to airway obstruction.

 

Question: In the context of blunt abdominal trauma, what is the significance of 'Cullen's sign' and 'Grey Turner's sign'?

Answer: They indicate possible intra-abdominal bleeding.

Explanation: Cullen's sign (bruising around the umbilicus) and Grey Turner's sign (flank bruising) are indicative of intra-abdominal hemorrhage, particularly of pancreatic or duodenal origin.

 

Question: What is the mainstay of treatment for a traumatic pneumothorax?

Answer: Chest tube insertion.

Explanation: The standard treatment for a traumatic pneumothorax is the placement of a chest tube to evacuate air from the pleural space and allow the lung to re-expand.

Question: Why is rapid sequence intubation (RSI) often used in trauma patients?

Answer: To secure the airway quickly while minimizing the risk of aspiration.

Explanation: RSI is a technique used to quickly induce unconsciousness and paralysis for intubation, reducing the risk of aspiration in patients with a full stomach or compromised airway reflexes.

 

Question: What are the components of the 'C-ABCDE' approach in trauma?

Answer: Catastrophic hemorrhage, Airway, Breathing, Circulation, Disability, Exposure.

Explanation: The 'C-ABCDE' approach adds Catastrophic hemorrhage as a priority before the standard 'ABCDE' to emphasize the importance of addressing massive bleeding early in trauma care.

 

Question: In pediatric trauma, what is a unique consideration compared to adults?

Answer: Greater risk of head injuries and physiological differences like higher heart rates and different responses to fluid loss.

Explanation : Pediatric patients are more prone to head injuries due to their larger head-to-body ratio. They also have physiological differences, such as a higher baseline heart rate and a different response to fluid loss and shock, necessitating adjustments in their assessment and management.

 

Question: What is the preferred method for securing an airway in a patient with severe maxillofacial injuries?

Answer: Surgical airway, such as cricothyroidotomy or tracheostomy.
