Final answer:
After a seizure in a pregnant client with epilepsy, the nurse should first check vital signs to monitor circulatory and respiratory status, then administer oxygen if needed and assess for any injuries.
Step-by-step explanation:
If a nurse observes a client at 26 weeks of gestation who has epilepsy having a seizure, immediately after the seizure the nurse should first ensure that the patient is breathing effectively. Turning the client's head to the side helps to maintain an open airway during the seizure, reducing the risk of aspiration. After the seizure, the nurse should check vital signs as a priority to assess the client's circulatory and respiratory status postictally (following the seizure). It is imperative to monitor the client's heart rate, blood pressure, respiratory rate, and oxygen saturation. Subsequently, the nurse should administer supplemental oxygen if required, based on the client's breathing and oxygenation status. Next, the nurse should assess for injuries that might have occurred during the seizure, such as trauma from falling or striking objects. The insertion of an oral airway is usually not needed post-seizure unless the client is unconscious or has an obstructed airway, in which case it should only be inserted by someone trained in the procedure to avoid potential injury.
