The nurse is teaching a client about the associated health risks of cocaine use. Which statement should the nurse use to describe how cocaine can cause myocardial infarction (MI)?
A)Cocaine significantly increases the serum triglyceride level, leading to the development of an atheroma.
B)Cocaine alters the body's clotting mechanisms, leading to thrombus formation.
C)Cocaine increases sympathetic nervous system stimulation, increasing blood pressure and vasoconstriction.
D)Cocaine alters electrolyte balance, leading to arrhythmias.

Question

Quizplus · Accepted Answer

A)Acute MI may develop as a result of cocaine intoxication. Cocaine increases sympathetic nervous system activity by both increasing the release of catecholamines from central and peripheral stores and interfering with the reuptake of catecholamines. This increased catecholamine concentration stimulates the heart rate and increases its contractility, increases the automaticity of cardiac tissues and the risk of dysrhythmias, and causes vasoconstriction and hypertension. The other answers do not occur with cocaine intoxication.
B)Acute MI may also develop as a result of cocaine intoxication. Cocaine increases sympathetic nervous system activity by both increasing the release of catecholamines from central and peripheral stores and interfering with the reuptake of catecholamines. This increased catecholamine concentration stimulates the heart rate and increases its contractility, increases the automaticity of cardiac tissues and the risk of dysrhythmias, and causes vasoconstriction and hypertension.
