Emergency Medical Technician (EMT) Intermediate Practice Exam

What is the correct positioning of an appropriately sized cervical collar?

1. Above the mandible and below the ears

2. Resting on the shoulder and providing support under the mandible

3. Aligned with the nose and chin

4. Extending from the jawline to the base of the neck

The correct answer is: Resting on the shoulder and providing support under the mandible

Positioning an appropriately sized cervical collar is crucial for providing effective immobilization and minimizing movement of the cervical spine in a patient who may have a neck injury. The correct positioning involves the collar resting on the shoulders, which helps to distribute support evenly and prevents excessive pressure that could cause discomfort or further injury. Additionally, support under the mandible is vital, as it ensures that the jaw is held in a neutral position, which is essential for maintaining the airway and preventing hyperextension or flexion of the neck. By properly supporting both the shoulders and mandible, the collar creates a stable and secure fit that effectively limits spinal motion. It is important that the collar does not extend too high, which could potentially push the jaw forward or impede the airway. In summary, the appropriate placement of the cervical collar maximizes support for the head while minimizing the risk of further injury to the cervical spine, thereby aligning with best practices for patient care in emergency situations.
