Which item is explicitly listed as a reevaluation adjunct?

• A. Tetanus shot
• B. Cervical Spine CT scan or x-ray
• C. Electrocardiogram
• D. Creatinine clearance

Answer: (B)

Reevaluation adjuncts are tests added to the ongoing assessment to detect injuries that may not be obvious during the initial survey. Among the options, imaging of the cervical spine—whether CT scan or x-ray—is the one explicitly listed as a reevaluation adjunct. Keeping the neck immobilized and reassessing if symptoms or risk factors change helps ensure you don’t miss a cervical spine injury as the patient’s condition evolves.

The tetanus shot is part of wound management, not a diagnostic reevaluation. An electrocardiogram is useful for monitoring cardiac status but isn’t specifically designated as a reevaluation adjunct in this context. Creatinine clearance measures kidney function and helps guide contrast use, but it isn’t an adjunct used to reevaluate trauma injuries.
