A nurse is caring for a client who is receiving treatment for alcohol detoxification. Which of the following medications should the nurse expect to administer during this phase of the client's care?

A. Buprenorphine is primarily used for the treatment of opioid dependence, not alcohol detoxification. It is a partial opioid agonist and can precipitate withdrawal symptoms in individuals dependent on opioids. Therefore, it is not appropriate for alcohol detoxification and would not typically be administered in this context.
B. Diazepam belongs to the benzodiazepine class of medications and is commonly used during alcohol detoxification. Benzodiazepines help manage symptoms of alcohol withdrawal, including anxiety, tremors, agitation, and seizures. They work by enhancing the effects of gamma-aminobutyric acid (GABA), which is an inhibitory neurotransmitter in the brain. Diazepam has a longer duration of action and is preferred in managing alcohol withdrawal due to its smoother pharmacokinetic profile compared to shorter-acting benzodiazepines.
C. Varenicline is a medication used for smoking cessation. It works by partially activating nicotine receptors in the brain, reducing the pleasurable effects of smoking and decreasing withdrawal symptoms. It is not indicated for alcohol detoxification and would not be used in this context.
D. Rimonabant is a cannabinoid receptor antagonist that was once used for weight loss but has been withdrawn from the market due to psychiatric side effects, including depression and anxiety. It is not indicated for alcohol detoxification and would not be administered in this context.

A. The PSDA applies to all adult clients regardless of age. It ensures that adults have the right to make decisions about their medical care, including the right to accept or refuse treatment, regardless of whether they are elderly or not. Age is not a factor in the applicability of the PSDA.
B. While it's common for a living will to be witnessed, it is not a legal requirement under the PSDA.
C. Advance directives are applicable to all clients, including those receiving mental health care.
D. The Patient Self-Determination Act (PSDA) ensures that adult patients are informed about their rights to make decisions regarding their medical care, including the right to accept or refuse treatment and to prepare an advance directive.
