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. Hearing loss: Alprazolam, a benzodiazepine medication, is not typically associated with hearing loss. Adverse effects related to hearing are not commonly reported with the use of alprazolam.

B. Insomnia: Insomnia, or difficulty falling or staying asleep, is a potential adverse effect of alprazolam. While benzodiazepines like alprazolam are central nervous system depressants and can cause drowsiness, paradoxical reactions such as insomnia may occur in some individuals.

C. Bradycardia: Alprazolam is not known to cause bradycardia. Instead, it may cause mild tachycardia or irregular heart rhythms as potential cardiovascular side effects.

D. Hypertension: Alprazolam is more likely to cause hypotension (low blood pressure) rather than hypertension. Hypotension is a potential adverse effect due to its central nervous system depressant effects, which can lead to relaxation of blood vessels and decreased blood pressure.

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.
