A nurse is providing medication teaching about disulfiram for a client who has alcohol use disorder. Which of the following statements by the client indicates an understanding of the teaching?

I will need to get a monthly injection of this medication.

My provider wants me to take this medication for 2 weeks before I try to quit drinking.

I should avoid over-the-counter medications that contain alcohol.

I need to continue this medication for at least 5 years.

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

Choice A reason: Removing a thermometer for use on another client risks cross-contamination, as C. difficile spores are highly transmissible. Dedicated equipment is required to prevent spread, so this action is incorrect and violates infection control protocols.
Choice B reason: Wearing a gown during care prevents C. difficile spore transmission via contact, a key precaution for this infection. This aligns with CDC contact isolation guidelines, protecting staff and other patients, making it the correct action.
Choice C reason: Washing hands with alcohol-based cleaner is ineffective against C. difficile spores, which require soap and water to physically remove them. This action is incorrect and inadequate for infection control in this scenario.
Choice D reason: Wearing an N95 respirator is unnecessary, as C. difficile is not airborne. Contact precautions (gown, gloves) suffice, so this action is incorrect and overprotective, wasting resources without addressing the transmission mode.

A. Limit your child's potassium intake while she is taking this medication. B. Repeat the dose if your child vomits within 1 hour after taking the medication. C. You can add the medication to a half-cup of your child's favorite juice. D. Have your child drink a small glass of water after swallowing the medication.

Correct Answer is D

Explanation

Choice A reason: Limiting potassium intake is dangerous with digoxin, as low potassium (hypokalemia) increases the risk of digoxin toxicity by enhancing drug binding to cardiac cells. Adequate potassium levels are critical for safe use, as digoxin affects cardiac contractility, making this instruction incorrect and potentially harmful.
Choice B reason: Repeating a digoxin dose if the child vomits within 1 hour is unsafe without medical consultation, as it risks overdose. Digoxin has a narrow therapeutic index, and toxicity can cause arrhythmias. Parents should contact the provider for guidance, making this instruction incorrect and dangerous.
Choice C reason: Adding digoxin to juice risks inaccurate dosing, as the child may not consume the full amount, leading to underdosing or toxicity if additional doses are given. Precise administration (e.g., via syringe) ensures correct dosing, critical for digoxin’s narrow therapeutic range, making this instruction inappropriate.
Choice D reason: Having the child drink water after digoxin ensures the dose is fully swallowed, preventing loss from spitting or incomplete ingestion. This supports accurate dosing, essential for digoxin’s safe use in heart failure, where it enhances cardiac output. This instruction is safe and effective, making it correct.
