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

Choice A reason: Cocaine use typically suppresses appetite due to its stimulant effects, not increases it. Polyphagia is more associated with conditions like hyperthyroidism or diabetes. Choice B reason: Cocaine stimulates the central nervous system, leading to hyperthermia (fever), tachycardia, hypertension, and agitation. These are hallmark signs of acute cocaine toxicity. Choice C reason: Cocaine causes sympathetic stimulation, which results in tachycardia—not bradycardia. Bradycardia would be an unexpected finding. Choice D reason: Cocaine does not directly cause oliguria. While dehydration or renal complications may occur in severe toxicity, oliguria is not a primary expected finding within 1 hour of use.
