To select an appropriate C-collar size, measurement is taken from the bottom of the chin to the top of which landmark?

• A. Shoulder
• B. Ear
• C. Nose
• D. Clavicle

Answer: (A)

Choosing the right cervical-collar size is all about neck length. The measurement is taken from the bottom of the chin to the top of the shoulder to determine how long the collar must be to properly immobilize the cervical spine. This distance ensures the collar extends from under the chin to the upper chest area, providing secure stabilization without riding up under the chin or leaving the lower neck exposed. A collar that reaches the top of the shoulder fits the design of standard collars and allows for proper alignment and fixation during immobilization, transfer, and imaging. Landmarks like the ear or nose don’t reflect how far down the neck needs to extend, and measuring to the clavicle can misjudge the necessary length for effective immobilization.
