Emergency Medical Technician (EMT) Practice Test

What interventions are typical treatments for closed head injuries?

1. Oxygen (O2)

2. Positive-pressure ventilation (PPV)

3. Monitoring level of consciousness (LOC)

4. Reversing Trendelenburg position

The correct answer is: Oxygen (O2)

Oxygen therapy is a typical intervention used for patients with closed head injuries because maintaining adequate oxygenation is crucial for brain function and recovery. In cases of head trauma, there can be swelling or increased intracranial pressure, which may compromise blood flow and oxygen delivery to the brain. Administering supplemental oxygen helps ensure that the tissues receive the necessary amount of oxygen, potentially reducing the risk of secondary brain injury. Monitoring the level of consciousness is also critical in managing closed head injuries, as changes can indicate worsening of the condition. However, it is part of ongoing assessment rather than a direct treatment intervention. Positive-pressure ventilation may be utilized if the patient's respiratory status requires it, but it is not a routine intervention for every closed head injury. The Trendelenburg position, which involves the patient lying flat on their back with the legs elevated, is not recommended for closed head injuries as it might increase intracranial pressure. Thus, oxygen therapy stands out as an essential and direct treatment for managing closed head injuries.
