Certified Addiction Registered Nurse (CARN) Exam Sample Questions
Question 1
Which of the following substances is primarily associated with an increased risk of
overdose when a patient develops tolerance?
A) Alcohol
B) Heroin
C) Nicotine
D) Caffeine
Correct Option: B) Heroin
Rationale:
Heroin is an opioid that is highly addictive. As a patient develops tolerance to heroin, they may
increase their dosage, significantly raising the risk of overdose. Opioids depress the central
nervous system, and overdose can lead to respiratory failure and death. Understanding the
relationship between tolerance and overdose risk is crucial for addiction prevention and patient
safety.
Question 2
In managing a patient in withdrawal from alcohol, what is the most appropriate nursing
intervention?
A) Encourage the patient to consume caffeine
B) Administer benzodiazepines as prescribed
C) Restrict fluid intake to prevent overload
D) Allow the patient to sleep for extended periods
Correct Option: B) Administer benzodiazepines as prescribed
Rationale:
Benzodiazepines are commonly used for managing alcohol withdrawal symptoms due to their
ability to mitigate seizures and alleviate anxiety. Withdrawing from alcohol can induce severe
symptoms, including hyperactivity and delirium tremens. It is crucial that the patient is closely
, monitored and provided with appropriate pharmacological interventions to ensure safety and
comfort.

What is the primary goal of motivational interviewing in addiction nursing?
A) Convincing the patient to enter treatment
B) Encouraging lifestyle changes
C) Helping the patient explore and resolve ambivalence
D) Teaching the patient about addiction
Correct Option: C) Helping the patient explore and resolve ambivalence
Rationale:
Motivational interviewing is a patient-centered counseling style aimed at eliciting behavior
change by helping individuals explore and resolve ambivalence. It empowers patients to take
ownership of their treatment journey. The foundation of motivational interviewing is to enhance
the patient’s intrinsic motivation to change by reinforcing their autonomy and recognizing their
feelings, leading to sustainable change.
Question 4
Which of the following is a key indicator of alcohol dependence?
A) Social withdrawal
B) Occasional binge drinking
C) Tolerance to alcohol effects
D) Enjoyment of social events
Correct Option: C) Tolerance to alcohol effects
Rationale:
Tolerance is one of the criteria for alcohol use disorder, signifying that the individual requires
increasing amounts of alcohol to achieve the desired effect or experiences diminished effects
with continued use of the same amount. Recognizing tolerance helps nurses assess the severity of
the substance use disorder and plan the appropriate interventions necessary for recovery.
