A nurse is teaching a female client who has a new diagnosis of systemic lupus erythematosus (SLE). The nurse should recognize the need for further teaching when the client identifies which of the following as a factor that can exacerbate SLE?

Choice A rationale:
Phenytoin is an anticonvulsant medication that is typically used long-term to control seizures. It is not a medication that can be stopped abruptly, as this can lead to the recurrence of seizures or even status epilepticus, a life-threatening condition characterized by continuous seizure activity.
The client's statement, "I'll be glad when I can stop taking this medicine," indicates a lack of understanding about the long- term nature of phenytoin therapy and the potential risks associated with stopping the medication prematurely.
Further teaching is needed to emphasize the importance of medication adherence and the potential consequences of non- adherence.

Choice B rationale:
Phenytoin can cause gingival hyperplasia (overgrowth of gum tissue), so it is important for clients taking this medication to see a dentist regularly for checkups and cleanings.
The client's statement, "I have made an appointment to see my dentist next week," indicates an understanding of this potential side effect and the need for regular dental care.

Choice C rationale:
Phenytoin has a narrow therapeutic index, meaning that there is a small difference between the effective dose and the toxic dose.
Switching brands of phenytoin can lead to changes in blood levels of the medication, which could potentially result in therapeutic failure or toxicity.
The client's statement, "I know that I cannot switch brands of this medication," indicates an understanding of this important safety consideration.

Choice D rationale:
Phenytoin can interact with many other medications, including over-the-counter medications and herbal supplements.
It is important for clients taking phenytoin to notify their doctor before taking any other medications to avoid potential drug interactions.
The client's statement, "I will notify my doctor before taking any other medications," indicates an understanding of this potential risk.

Choice A rationale:
Protecting the airway is the highest priority during a tonic-clonic seizure. Tonic-clonic seizures involve intense muscle contractions, which can lead to biting the tongue, aspiration of secretions, or even respiratory arrest if the airway is obstructed. Turning the client's head to the side helps to maintain a clear airway and prevent these complications.
It is essential to act quickly to prevent injury and ensure adequate oxygenation. Delaying airway management could have serious consequences.

Choice B rationale:
Checking motor strength is not a priority during the active phase of a seizure. It is more important to focus on protecting the airway and preventing injury.
Motor strength can be assessed after the seizure has subsided.

Choice C rationale:
Loosening clothing around the waist may be helpful to promote comfort and breathing, but it is not the first priority. It is more important to address the airway and prevent aspiration.

Choice D rationale:
Documenting the time the seizure began is important for accurate record-keeping and assessment of seizure patterns, but it is not the first priority in the immediate management of the seizure. Documentation can be done after the client's airway and safety are ensured.
