A charge nurse is teaching a group of nurses about the antagonist action of medications. The nurse should include in the teaching that which of the following antagonist medications is used for benzodiazepines?

A. Avoid flossing the teeth to prevent gum irritation: There is no evidence to suggest that flossing the teeth increases the risk of gum irritation with phenytoin use. In fact, proper dental hygiene, including flossing, is essential to prevent gum disease, which can be exacerbated by the medication.

B. Alcohol increases the chance of phenytoin toxicity: Consumption of alcohol can increase the risk of phenytoin toxicity by enhancing its effects. Therefore, clients taking phenytoin should avoid alcohol consumption to prevent adverse effects and ensure the medication's efficacy.

C. Take an antacid with the medication if indigestion occurs: Phenytoin can interact with antacids, reducing its absorption and effectiveness. Therefore, clients should not take antacids concurrently with phenytoin unless directed by their healthcare provider.

D. Phenytoin turns urine blue: Phenytoin does not typically cause changes in urine color. This statement is incorrect and not relevant to the client's medication regimen.

A. A pretreatment electroencephalogram (EEG) is not typically required before starting valproate therapy. EEGs may be used in the diagnosis and management of seizure disorders, but they are not a standard part of valproate therapy initiation.

B. High serum sodium levels are not associated with toxic levels of valproate. Instead, valproate can cause hyperammonemia, especially in individuals with urea cycle disorders.

C. Thyroid function tests are not typically required specifically for valproate therapy. However, valproate may interfere with thyroid hormone levels, so thyroid function tests might be ordered if there are symptoms of thyroid dysfunction.

D. Monitoring liver function tests is essential when taking valproate because the medication can cause hepatotoxicity. Clients should have baseline liver function tests before starting valproate, followed by regular monitoring throughout treatment. If liver function test results indicate liver damage, the healthcare provider may adjust the dosage or discontinue the medication. Therefore, this is the correct instruction to provide to the client starting valproate therapy.
