After a patient has stopped seizing, what is the least critical action for EMTs to take upon arrival?

Upon arrival at the scene after a patient has stopped seizing, determining the last hospital visit for seizures is the least critical action for EMTs to take. This information, while potentially helpful for understanding the patient's medical history and ongoing needs, does not directly impact the immediate treatment or stabilization of the patient.

In contrast, suctioning is a priority if there is any risk of aspiration or airway obstruction due to oral secretions. Administering oxygen may be essential, especially if the patient is hypoxic or showing signs of respiratory distress following the seizure. Checking for mechanism of injury ensures that any potential trauma is addressed, helping to rule out other complications that may require urgent attention. These actions are more immediately relevant for the patient's safety and stabilization than determining past medical visits.
