What should be done immediately for a patient experiencing a seizure?

When a patient is experiencing a seizure, the primary focus is on ensuring their safety and minimizing the risk of injury. Clearing the area around the patient is crucial because it prevents the patient from coming into contact with any hazardous objects or surfaces that could cause harm during the seizure. Protecting the patient's head is particularly important, as head injuries are common during seizures due to involuntary movements and potential falls.

Restraint is not advisable during a seizure since moving or holding the person can lead to further injury. Likewise, placing an object in the patient's mouth is counterproductive; it does not prevent biting and can lead to airway obstruction or dental injuries. Leaving the patient alone fails to provide necessary assistance and could result in serious injuries. Thus, the correct action is to ensure the environment is safe and to protect the patient appropriately during the seizure episode.
