The client newly diagnosed with epilepsy begins to show signs of seizure activity. What is the nurse's priority action?

A. Obtain the client's vital signs as soon as possible: While vital signs are important, they are not the immediate priority during active seizure activity. The focus should first be on preventing injury and maintaining airway safety before assessing physiological parameters. B. Attempt to calm the client: During a seizure, the client is typically unconscious or unaware and cannot be calmed verbally. This intervention is ineffective at that moment and does not contribute to immediate safety. C. Protect the client's safety: The top priority during a seizure is to prevent injury by padding side rails, loosening tight clothing, and turning the client to the side if possible to maintain airway patency and prevent aspiration. D. Perform detailed documentation: Documentation is essential but should occur after the seizure ends. Accurate notes are important for care planning, but they are not the immediate focus while the client is actively seizing.
