A nurse in an emergency department is assessing a client who reports recently using cocaine. Which of the following clinical manifestations should the nurse expect?

Choice A reason: Cocaine is a powerful stimulant drug that can cause an acute increase in heart rate and blood pressure. Hypertension is a common clinical manifestation associated with cocaine use due to its sympathomimetic effects, which stimulate the sympathetic nervous system. This can lead to vasoconstriction and increased cardiac output, resulting in elevated blood pressure levels. Choice B reason: Hypothermia is not typically associated with cocaine use. Cocaine tends to increase body temperature due to its stimulant properties, which can lead to hyperthermia rather than hypothermia. If hypothermia is present in a client who has used cocaine, it may be due to other factors or substances that the client has ingested. Choice C reason: Bradycardia, or a slower than normal heart rate, is not a common effect of cocaine use. Cocaine usually causes tachycardia, an increased heart rate, as part of its stimulant effect on the body. Bradycardia would be an unusual response and might suggest other medical issues or the influence of other substances.
