When a patient is experiencing a seizure, the primary focus is on ensuring their safety and providing comfort. Placing a towel or blanket under the head serves to protect the patient from injury due to any potential movements or impacts against a hard surface. This action helps to cushion the head, which is vulnerable during a seizure, reducing the risk of trauma.

Additionally, it is essential to keep the area around the patient clear of any objects that could cause harm and to monitor the duration of the seizure. After the seizure, positioning the patient safely on their side can also help to maintain an open airway and prevent choking.

The other options, such as tightening the patient's clothing or placing an object in their mouth, are harmful practices that could lead to further injury or complications during a seizure. Restraining a person during a seizure is not advisable, as it can cause additional harm to both the patient and the caregiver.
