A nurse is teaching a client who has a newly documented latex allergy. Which of the following statements by the client indicates an understanding of the teaching?

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.

Choice A reason: Placing the client in semi-Fowler’s position for postoperative assessment is appropriate, promoting lung expansion and reducing aspiration risk. This aligns with standard care, supporting respiratory function and comfort, requiring no further instruction as it reflects safe, evidence-based practice.
Choice B reason: Auscultating lungs without lifting the gown may reduce clarity but is not unsafe. It preserves modesty and is acceptable if effective. While lifting the gown is preferred, this action poses minimal risk, requiring less instruction compared to errors with immediate safety implications.
Choice C reason: Administering an enema without checking for contraindications, like bowel obstruction, risks complications such as perforation. This reflects poor assessment, necessitating instruction to ensure the nurse verifies patient safety and chart details before invasive procedures to prevent harm.
Choice D reason: Checking vital signs before cardiac medication is correct, ensuring safety (e.g., withholding beta-blockers for low heart rate). This follows pharmacological protocols, requiring no instruction, as it demonstrates competence in safe medication administration practices on a medical-surgical unit.
