EFMB Medical Skills & Combat Medicine — Questions and Answers
Question 1: What is the primary function of the tourniquet in combat medicine?
- To administer medication.
- To stabilize fractures.
- To stop arterial blood flow and control severe bleeding (Correct answer)
- To reduce swelling.
Correct answer: To stop arterial blood flow and control severe bleeding
The primary function of a tourniquet in combat medicine is to rapidly and completely stop severe, life-threatening arterial and venous bleeding from a limb. When applied correctly and tightly, it occludes blood flow, preventing hemorrhagic shock and saving a casualty's life in situations where direct pressure is insufficient. This makes it a critical tool for immediate hemorrhage control in tactical environments.
Question 2: When should a combat medic apply a chest seal?
- For any open wound.
- Only for abdominal wounds.
- For gunshot or shrapnel wounds to the chest (Correct answer)
- When there is severe bleeding in the arm.
Correct answer: For gunshot or shrapnel wounds to the chest
A combat medic should apply a chest seal specifically for penetrating trauma to the chest, such as gunshot or shrapnel wounds, which can lead to an open pneumothorax. These wounds create an opening in the chest wall, allowing air to enter the pleural space and collapse the lung. A chest seal creates an airtight barrier, preventing further air entry and helping to restore normal lung function, which is critical for preventing tension pneumothorax.
Question 3: What is the primary goal of combat casualty care in the field?
- To transport casualties as quickly as possible.
- To provide immediate surgery.
- To stabilize the patient for evacuation and further care (Correct answer)
- To provide emotional support.
Correct answer: To stabilize the patient for evacuation and further care
The primary goal of combat casualty care in the field is to provide immediate, life-saving interventions to stabilize the patient's condition. This stabilization focuses on addressing preventable causes of death, such as massive hemorrhage, airway obstruction, and tension pneumothorax, to prepare the casualty for safe evacuation. The aim is to bridge the gap until definitive medical care can be provided at a higher echelon of care.
Question 4: Which of the following is a common complication of untreated tension pneumothorax?
- Severe headache.
- Decreased blood pressure and respiratory distress (Correct answer)
- Swelling in the extremities.
- Abdominal cramps.
Correct answer: Decreased blood pressure and respiratory distress
Untreated tension pneumothorax is a life-threatening condition where air accumulates in the chest cavity, compressing the affected lung and shifting the mediastinum, which includes the heart and major blood vessels. This compression leads to decreased venous return to the heart, resulting in a rapid drop in blood pressure (hypotension) and severe respiratory distress as the healthy lung is also compromised. Prompt recognition and decompression are critical to prevent circulatory collapse and death.
Question 5: How should a combat medic manage an open abdominal wound?
- Apply pressure and cover with a sterile dressing (Correct answer)
- Apply cold compresses and leave it uncovered.
- Use a tourniquet to stop internal bleeding.
- Do nothing until evacuation.
Correct answer: Apply pressure and cover with a sterile dressing
When managing an open abdominal wound, a combat medic should apply pressure and cover the wound with a sterile, moist dressing. The goal is to protect exposed organs from contamination, prevent further evisceration, and maintain moisture. Unlike limb injuries, a tourniquet is not appropriate for abdominal wounds, and leaving it uncovered increases the risk of infection and further injury.
Question 6: What is the primary concern when treating a casualty with shock?
- Administer pain medication.
- Ensure the casualty is kept warm and hydrated.
- Restore circulation and oxygen to vital organs (Correct answer)
- Provide high doses of adrenaline.
Correct answer: Restore circulation and oxygen to vital organs
When a casualty is in shock, their body's vital organs are not receiving enough blood flow and oxygen, which can quickly lead to organ damage or failure. Restoring circulation and oxygen is paramount to prevent irreversible damage and save the casualty's life. This often involves controlling bleeding, maintaining an open airway, and supporting breathing, which are critical steps in tactical combat casualty care (TCCC).
Question 7: What is the purpose of the 'MARCH' acronym in tactical combat casualty care?
- To address symptoms of dehydration.
- To treat only head injuries.
- To prioritize life-threatening injuries in a systematic order (Correct answer)
- To minimize patient interaction.
Correct answer: To prioritize life-threatening injuries in a systematic order
The MARCH acronym (Massive Hemorrhage, Airway, Respiration, Circulation, Head injury/Hypothermia) provides a systematic and prioritized approach to treating life-threatening injuries in a tactical environment. By addressing these issues in order, combat medics ensure that the most immediate and critical threats to life are managed first. This structured approach is essential for effective and efficient care under pressure, maximizing the chances of survival for the casualty.
Question 8: Why is it important to quickly recognize signs of a traumatic brain injury (TBI) in the field?
- To prevent bleeding in the skull.
- To ensure quick evacuation and treatment (Correct answer)
- To provide emotional support.
- To keep the patient conscious.
Correct answer: To ensure quick evacuation and treatment
Quick recognition of a traumatic brain injury (TBI) is crucial because these injuries can rapidly worsen and lead to severe neurological damage or death if not managed promptly. Early identification allows for immediate intervention, such as maintaining an open airway and monitoring for changes in consciousness, and facilitates rapid evacuation to a higher level of medical care. Timely treatment can significantly improve the casualty's prognosis and reduce long-term disability.
Question 9: What should a combat medic do after applying a tourniquet to stop severe bleeding?
- Remove the tourniquet once bleeding slows.
- Check and document the time of application (Correct answer)
- Leave the casualty alone until evacuation.
- Apply more pressure.
Correct answer: Check and document the time of application
After applying a tourniquet, it is critical to check and document the time of application. This information is vital for subsequent medical personnel to know how long the tourniquet has been in place, which influences decisions regarding further treatment and potential complications like ischemia. Proper documentation ensures continuity of care and helps prevent unnecessary tissue damage.
