Advanced Trauma Life Support (ATLS) Practice Exam

Which exam finding is associated with a potential airway obstruction?

1. Trismus

2. Raccoon eyes

3. Crepitus in cervical spine

4. Foreign body in nares

The correct answer is: Trismus

Trismus, often referred to as a "locked jaw," is a condition characterized by the inability to open the mouth fully due to muscle spasms or trauma. This physical limitation can have significant implications for airway management because it inhibits the ability to perform essential procedures such as oral intubation or the use of bag-mask ventilation. In the context of airway obstruction, trismus suggests possible underlying issues such as maxillofacial injuries, temporomandibular joint dysfunction, or even severe infections that can compromise the airway. When the mouth cannot be opened adequately, it may restrict the access needed to secure the airway, making it a critical finding to note during an assessment. The other options, while they may indicate various injuries or conditions, do not directly relate to immediate concerns about airway access and obstruction.
