Which of the following is a potential complication if a cervical collar is not properly managed?

Worsening spinal injury is indeed a significant potential complication if a cervical collar is not properly managed. Cervical collars are used to stabilize the spine and prevent further injury, especially in cases of suspected cervical spine trauma. If the collar is applied incorrectly, it may not provide adequate immobilization, allowing for excessive movement of the cervical vertebrae. This movement can exacerbate an existing spinal injury, potentially leading to increased nerve damage, paralysis, or other severe consequences.

Proper management of the cervical collar involves ensuring that it is correctly fitted and adjusted to maintain stability without causing additional discomfort or impairing circulation. Neglecting these aspects can directly compromise the safety of the patient and may worsen their injury rather than provide the necessary support and protection.

In contrast, increased circulation, improved airway management, and reduction of neck pain are outcomes not typically associated with improper cervical collar application. In fact, improper collar management could hinder circulation and airway management due to improper alignment and may lead to increased discomfort rather than pain relief. Thus, recognizing the importance of correct cervical collar management is critical in trauma care to prevent further complications.
