What is a contraindication for applying a cervical collar?

Applying a cervical collar is primarily intended to immobilize the head and neck in cases of potential spinal injury. The correct choice identifies unconscious patients as a contraindication for applying a cervical collar due to specific concerns regarding airway management. In an unconscious individual, there is a heightened risk that the airway may be compromised.

If a cervical collar is applied without proper considerations, it could make it more difficult for rescuers to ensure that the patient’s airway remains secure and clear. Additionally, unconscious patients may have altered muscle tone or reflexes, which could complicate the application of a collar and might not provide the needed stabilization for someone who is unresponsive.

Conscious patients, those with mild neck pain, and those with headaches do not necessarily have a direct contraindication for the use of a cervical collar, as they can communicate their symptoms and cooperate with medical staff, allowing for a proper assessment and management of their condition.
