The nurse is preparing a client for discharge after treatment for cocaine abuse. The client is taking home a prescription for a new medication to control cocaine cravings. Which intervention is most important for the nurse to implement?

Choice A rationale: While assessing for symptoms of cocaine withdrawal is important, educating the client about the purpose and side effects of the medication is the priority when initiating new pharmacological treatment. Choice B rationale: Educating the client about the purpose and side effects of the medication promotes understanding and adherence to the treatment plan, addressing the client's cravings. Choice C rationale: Encouraging the client to take the medication as prescribed is important, but educating them about the medication takes precedence. Choice D rationale: Determining when the client last used cocaine is relevant but does not directly address the education needed for medication management.
