Which assessment would be performed first during the primary survey?

The primary survey is a crucial component of patient assessment used to quickly identify and address life-threatening conditions. The correct choice of performing the assessment of airway first is essential because the airway is the pathway for oxygen and ventilation. If the airway is compromised, it directly affects the patient's ability to breathe and can lead to hypoxia, which is life-threatening.

During the primary survey, the EMT's primary goal is to ensure that the airway is patent (open) and not obstructed. If the airway is blocked, no amount of breathing assistance or circulation support will be effective. Therefore, confirming that the airway is clear allows the EMT to proceed to reassess breathing and circulation with the assurance that the patient is capable of receiving oxygen.

The other assessments play a vital role in the primary survey but follow after ensuring the airway is unobstructed. Assessing circulation, breathing, or the environment is important, but they cannot effectively be addressed if the airway is not secured first.
