The practical nurse (PN) is caring for a client whose urine drug screen is positive for cocaine. Which behavior is most likely seen in this client?

A. Elevated energy level: While cocaine use can initially cause increased energy, this is a temporary effect. The most consistent and concerning behavioral manifestation is drug-seeking behavior due to intense cravings. B. Powerful craving for more: Cocaine is highly addictive and stimulates the brain's reward system, leading to a powerful and often uncontrollable craving for more of the drug, which is a hallmark of cocaine dependence. C. High self-esteem: Cocaine use may cause temporary grandiosity, but it does not result in true or stable high self-esteem. Users often experience mood swings and depressive symptoms after the drug wears off. D. Euphoria: Cocaine does cause euphoria, but it is short-lived. The craving for more, even after the initial high, is more defining and persistent in clients who test positive and are in the cycle of use.
