A nurse is providing education to a client who is reviewing a consent form for a surgical procedure. Which of the following statements by the client indicates an understanding of the consent?

Choice A reason: Thinking about wanting the procedure shows indecision, not consent understanding. Informed consent requires comprehension of the procedure, risks, and benefits, ensuring voluntary agreement. Contemplation alone is incomplete, failing to confirm the client’s grasp of the consent form’s legal purpose.
Choice B reason: Stating that signing indicates permission reflects understanding of informed consent, which documents voluntary agreement after receiving procedure details, risks, and benefits. This aligns with ethical and legal standards, confirming the client’s comprehension of the consent form’s role in authorizing surgery.
Choice C reason: Asking about risks indicates engagement but not consent understanding. It suggests a need for more information, not confirmation of the form’s purpose. While important, it does not reflect comprehension of the consent process as clearly as acknowledging the act of signing.
Choice D reason: Wanting to discuss concerns with the doctor shows the client seeks clarification, not that they understand the consent form’s purpose. It indicates an ongoing process, not confirmation of the form’s role in granting permission, unlike acknowledging the signing’s significance.

Choice A reason: Disulfiram is an oral medication, not injectable, used to deter alcohol consumption by causing adverse reactions. Monthly injections apply to drugs like naltrexone, not disulfiram, which requires daily oral dosing to maintain its deterrent effect in alcohol use disorder treatment.
Choice B reason: Taking disulfiram before quitting alcohol is incorrect, as it is started post-abstinence to prevent relapse. Disulfiram inhibits aldehyde dehydrogenase, causing acetaldehyde buildup if alcohol is consumed, making it effective only in alcohol-free clients to deter drinking.
Choice C reason: Avoiding over-the-counter medications with alcohol is correct, as disulfiram causes severe reactions (nausea, flushing) with alcohol ingestion, including from medications like cough syrups. This reflects understanding of disulfiram’s mechanism, ensuring safety by preventing unintended alcohol exposure.
Choice D reason: Continuing disulfiram for 5 years is not standard, as duration varies per treatment plan. Disulfiram supports early abstinence, not fixed long-term use. This statement misrepresents its role, as therapy length depends on individual recovery needs, not a predetermined timeframe.
