The nurse is performing intake interviews at a psychiatric clinic. A female client with a known history of drug abuse reports that she had a heart attack four years ago. Use of which substance places the client at highest risk for myocardial infarction?

Choice A reason: Marijuana may increase heart rate but has a lower risk for myocardial infarction compared to methamphetamine. Methamphetamine’s intense vasoconstriction and catecholamine surge directly precipitate cardiac ischemia, making marijuana less likely to have caused the client’s heart attack, thus incorrect for highest risk.Choice B reason: Benzodiazepines are sedatives with minimal direct cardiac effects, unlike methamphetamine, which causes severe vasoconstriction and hypertension, increasing infarction risk. Benzodiazepines are not strongly linked to myocardial infarction, making this incorrect for the substance posing the highest risk in this client’s history.Choice C reason: Chronic alcohol use contributes to cardiomyopathy but is less likely to cause acute myocardial infarction than methamphetamine, which induces intense coronary vasospasm and stress. Alcohol’s cardiac effects are more gradual, making this incorrect for the highest-risk substance for the client’s prior heart attack.Choice D reason: Methamphetamine, a potent stimulant, causes severe vasoconstriction, hypertension, and catecholamine release, significantly increasing myocardial infarction risk through coronary artery spasm and ischemia. This aligns with cardiology evidence for drug-induced cardiac events, making it the substance posing the highest risk for the client’s heart attack.
