Final answer:
The first action when a patient is having a seizure is to ensure their safety by moving them away from harm and cushioning their head, without restraining them or placing objects in their mouth. Immediately after, call for medical help.
Step-by-step explanation:
Upon entering your patient's room and noting that they are having a seizure, your first action should be to ensure their safety. This involves positioning the patient to prevent injury, such as moving them away from sharp objects and providing a cushion for their head. While it is essential to monitor vital signs and duration of the seizure, immediate action focuses on the patient's physical safety. It is not appropriate to restrain the patient or place anything in their mouth. After ensuring safety, seek additional medical help and prepare to give a report on the seizure characteristics, including any medical history that is relevant, such as the patient's history of epilepsy.
