How should a nurse describe the clonic phase of a tonic-clonic seizure?

The clonic phase of a tonic-clonic seizure is characterized by spasmodic body jerking, which is a result of rapid and rhythmic muscle contractions. During this phase, the individual experiences a series of convulsions that can vary in duration. This jerking can involve different muscle groups, causing movements that may be observable as limbs thrashing or shaking. This phase follows the tonic phase, where the body initially becomes stiff due to sustained muscle contraction.

The other options describe different aspects of a tonic-clonic seizure or related phases. Loss of consciousness is a characteristic of the entire seizure, including both the tonic and clonic phases. Stiffening of the body refers specifically to the tonic phase, while postictal confusion occurs after the seizure has ended, as the person slowly regains awareness and may have a period of disorientation. Therefore, the defining feature of the clonic phase is indeed the spasmodic body jerking that distinguishes it from other phases of the seizure.
