In caring for a client who requires seizure precautions, the practical nurse (PN) should ensure the ready availability of equipment to perform which procedure?

The correct answer is A: Suction the trachea. During a seizure, a client may experience excessive secretions or vomit, which can obstruct the airway. Suctioning the trachea helps maintain a clear airway, preventing aspiration and ensuring oxygenation. The other options are incorrect because: B) Inserting a urinary catheter is not directly related to seizure precautions. C) Applying soft restraints may not be necessary and could potentially exacerbate the client's distress during a seizure. D) Inserting a nasogastric tube is not a priority during a seizure and may not be indicated. Overall, ensuring the availability of equipment to suction the trachea is crucial in managing a client with seizure precautions.
