These materials are tailored to the exam content and are designed to help candidates familiarize themselves with the structure and difficulty level of the exam.
Join Study Groups:
Collaborating with other nurses preparing for the exam can be an effective way to deepen your understanding of complex topics. Study groups allow you to share resources, discuss difficult concepts, and clarify doubts.

Practice exams help you familiarize yourself with the exam format and test your knowledge. These exams can also help you manage your time during the actual test and identify areas where you need to improve.
Attend Continuing Education Courses:

The CARN (Certified Addictions Registered Nurse) credential is issued by the Addictions Nursing Certification Board (ANCB) and validates specialized knowledge in substance use disorders, withdrawal management, and recovery support.

Try these questions from our free Certified Addictions Registered Nurse practice tests. The correct answer and an explanation follow each question.
A nurse is working with a patient who relapses after 6 months of sobriety. Using a therapeutic frame consistent with addictions nursing, the nurse should:
Answer: B. Explore the relapse as a learning opportunity and adjust the treatment plan
Relapse is viewed as a common part of the recovery process; the therapeutic response is to analyze what happened, reinforce engagement, and revise the plan accordingly.
A nurse is developing a plan of care for an Indigenous client who is struggling with alcohol use disorder. The client expresses that they find more healing in traditional ceremonies than in conventional group therapy. To provide culturally competent care, what should be the nurse's first step?
Answer: C. Acknowledge the client's beliefs and explore ways to integrate traditional healing practices with the evidence-based treatment plan.
Cultural competence in addiction treatment involves understanding, respecting, and integrating the client's diverse cultural beliefs and values into their care. Rather than imposing a single treatment model, the nurse should collaborate with the client to create a holistic plan that respects their cultural identity. Acknowledging their beliefs and finding ways to integrate traditional practices, such as involving a community elder or allowing participation in ceremonies alongside clinical treatment, is a hallmark of patient-centered, culturally competent care.
A nurse on an inpatient detoxification unit has a strong suspicion that a colleague is diverting opioid medications intended for patients. The nurse observes the colleague frequently taking breaks after medication administration and notes several documentation discrepancies. What is the nurse's primary ethical and professional responsibility in this situation?
Answer: B. Report the suspicions immediately to the nursing supervisor or through the facility's established reporting channels.
According to the American Nurses Association (ANA) Code of Ethics, the nurse's primary commitment is to the patient's safety. When impaired practice is suspected, especially involving drug diversion which endangers patients, the nurse has an obligation to report these concerns to the appropriate authority (e.g., a manager or supervisor) to protect patients from harm. Waiting to gather more evidence or confronting the colleague directly could place patients at further risk.
A client who is stable in treatment for Opioid Use Disorder (OUD) with buprenorphine is newly diagnosed with Generalized Anxiety Disorder (GAD). The addictions nurse should anticipate the provider will AVOID prescribing which class of medication due to its high potential for misuse and dangerous synergistic effects?
Answer: D. Benzodiazepines
Benzodiazepines, when combined with opioids like buprenorphine, significantly increase the risk of life-threatening respiratory depression. They also have a high potential for misuse and dependence, making them a high-risk choice for a client with a pre-existing substance use disorder. SSRIs, buspirone, and hydroxyzine are considered safer, non-addictive alternatives for managing anxiety in this population.
