A nurse suspects a client who has myasthenia gravis is experiencing a myasthenic crisis. Which of the following interventions should the nurse take?

Hemorrhagic stroke is a type of stroke that occurs when a blood vessel ruptures in the brain, causing bleeding and increased intracranial pressure. The client's symptoms of sudden, severe headache, vomiting, seizure, and

unresponsiveness are consistent with hemorrhagic stroke. The client's elevated blood pressure and temperature are also risk factors for hemorrhagic stroke.

Thrombotic stroke is a type of stroke that occurs when a blood clot forms in an artery that supplies blood to the brain, causing ischemia and tissue damage. The client's symptoms are not typical of thrombotic stroke, which usually has a gradual onset and affects one side of the body.

Transient ischemic atack (TIA) is a temporary interruption of blood flow to the brain, causing neurologic deficits that resolve within 24 hours. The client's symptoms are not indicative of TIA, which does not cause loss of consciousness or permanent brain damage.

Embolic stroke is a type of stroke that occurs when a blood clot or other debris travels from another part of the body to the brain, causing occlusion and ischemia. The client's symptoms are not characteristic of embolic stroke, which usually has a sudden onset and affects one side of the body.

Phenytoin is an anticonvulsant medication that is used to prevent and treat seizures. It works by stabilizing the electrical activity of the brain and reducing the spread of abnormal impulses. Phenytoin is usually taken for life or until the seizures are controlled by other means, such as surgery or diet. The client should not stop taking phenytoin without consulting their doctor, as this can cause withdrawal symptoms or increase the risk of seizures.

The other options are correct and indicate that the client understands the discharge teaching because:

1. "I have made an appointment to see my dentist next week." This statement is correct because phenytoin can cause gingival hyperplasia, which is an overgrowth of gum tissue that can lead to bleeding, infection, or difficulty chewing. The client should practice good oral hygiene and see their dentist regularly to prevent or treat this condition.

1. "I will notify my doctor before taking any other medications." This statement is correct because phenytoin can interact with many other medications, such as antibiotics, anticoagulants, oral contraceptives, or antacids. These interactions can affect the blood levels and effectiveness of phenytoin or the other medications, causing adverse effects or reduced seizure control. The client should inform their doctor of any other medications they are taking or planning to take, including over-the-counter, herbal, or dietary supplements.
2. "I know that I cannot switch brands of this medication." This statement is correct because different brands of phenytoin may have different formulations or bioavailability, which can affect the absorption and metabolism of the drug. Switching brands can cause changes in the blood levels and effectiveness of phenytoin, leading to toxicity or reduced seizure control. The client should always use the same brand of phenytoin and check with their pharmacist if they notice any changes in the appearance or labeling of their medication.
