Final answer:
After a seizure, the nurse should immediately place the client in a lateral recovery position to maintain an open airway and prevent injury.
Step-by-step explanation:
The nurse should immediately place the client in a lateral recovery position after a seizure. This position helps to maintain an open airway and prevent aspiration of any fluids or vomit. It also helps to prevent the client from injuring themselves during the post-seizure period. Administering oxygen may be necessary if the client is experiencing respiratory distress, but placing the client in a lateral recovery position takes priority.
