A nurse is assessing a client who reports using cocaine 1 hour ago. Which of the following findings should the nurse expect?

A. Polyphagia. Cocaine is a stimulant that typically suppresses appetite rather than increasing it. Clients who use cocaine often experience decreased hunger rather than excessive eating (polyphagia). B. Fever. Cocaine use increases dopamine and norepinephrine levels, leading to hypermetabolic activity, which can cause fever, diaphoresis, and hyperthermia. Severe cases may result in malignant hyperthermia or seizures, making this a common and concerning symptom. C. Bradycardia. Cocaine is a powerful sympathomimetic that stimulates the fight-or-flight response, leading to tachycardia (fast heart rate), hypertension, and vasoconstriction. Bradycardia (slow heart rate) is not expected after cocaine use. D. Oliguria. Cocaine does not typically cause direct kidney impairment or reduced urine output (oliguria) unless there is severe rhabdomyolysis or renal damage from prolonged use. Instead, users often experience increased energy and activity without immediate kidney effects.
