DISCLAIMER: The following are original, high-difficulty study questions designed
for educational preparation. They are not actual CARN-AP examination questions,
recalled examination questions, or a reproduction of any certification examination.
QUESTION 1.
A 34-year-old patient presents to an addiction treatment clinic reporting daily
fentanyl use, three previous nonfatal overdoses, and repeated attempts to stop
,using without sustained success. The patient states, “I don't really want to quit
forever, but I am tired of surviving overdose after overdose.” Which advanced-
practice intervention best reflects a clinically appropriate initial approach?
A. Require the patient to commit to complete abstinence before initiating
pharmacotherapy
B. Initiate a collaborative treatment plan that prioritizes immediate overdose-risk
reduction while exploring readiness for longer-term recovery
C. Refer the patient to residential treatment because repeated overdose
automatically indicates inability to participate in outpatient care
D. Delay treatment until the patient demonstrates sustained motivation to
discontinue opioid use
🔴 Correct Answer: B. Initiate a collaborative treatment plan that prioritizes
immediate overdose-risk reduction while exploring readiness for longer-term
recovery
🔵 Explanation: The patient's ambivalence does not eliminate the opportunity for
effective treatment. A harm-reduction and recovery-oriented approach can address
immediate mortality risk, including access to naloxone and evidence-based treatment
for opioid use disorder, while continuing motivational work around the patient's goals.
Requiring abstinence or motivation before treatment creates an unnecessary barrier,
and repeated overdose alone does not automatically determine the appropriate level
of care.
QUESTION 2.
A patient with severe alcohol use disorder presents 14 hours after the last drink
with tremor, diaphoresis, anxiety, tachycardia, nausea, and perceptual disturbances.
The patient has a documented history of withdrawal seizures. Which clinical
reasoning is most appropriate?
A. The absence of generalized tonic-clonic activity means the patient remains low
risk for complicated withdrawal
B. Perceptual disturbances establish that the patient has developed primary
psychosis rather than alcohol withdrawal
C. The history and evolving autonomic findings indicate substantial risk for severe
withdrawal and warrant close monitoring with appropriately escalated withdrawal
,management
D. The patient should receive antipsychotic monotherapy because hallucinations are
the dominant presenting symptom
🔴 Correct Answer: C. The history and evolving autonomic findings indicate
substantial risk for severe withdrawal and warrant close monitoring with
appropriately escalated withdrawal management
🔵 Explanation: A previous withdrawal seizure is a major risk factor for future
complicated withdrawal, and autonomic hyperactivity with perceptual disturbances
can occur during alcohol withdrawal. The absence of a current seizure does not
eliminate risk. Primary psychosis should not be assumed solely from perceptual
symptoms occurring in a temporally appropriate withdrawal syndrome, and
antipsychotic monotherapy does not adequately address the underlying withdrawal
physiology.
QUESTION 3.
An advanced practice addiction nurse evaluates a patient who reports injecting
drugs and sharing injection equipment with a partner. The patient refuses
abstinence-based treatment but agrees to discuss ways to reduce infectious and
overdose risks. Which intervention best demonstrates contemporary harm-
reduction practice?
A. Provide sterile injection supplies, overdose-prevention education, naloxone
access, and testing/linkage for infectious diseases while maintaining engagement in
care
B. Withhold harm-reduction services until the patient agrees to enter medication
treatment
C. Focus exclusively on hepatitis C screening because overdose prevention is
outside addiction nursing practice
D. Explain that continued injection drug use makes preventive counseling clinically
inappropriate
🔴 Correct Answer: A. Provide sterile injection supplies, overdose-prevention
education, naloxone access, and testing/linkage for infectious diseases while
maintaining engagement in care
, 🔵 Explanation: Harm reduction seeks to reduce morbidity and mortality without
requiring immediate abstinence as a prerequisite for care. Injection-related infectious
disease prevention, overdose education, naloxone, sterile equipment, and linkage to
treatment can be delivered concurrently. Withholding preventive interventions
because the patient is not ready for abstinence conflicts with patient-centered and
evidence-informed addiction care.
QUESTION 4.
A patient stabilized on buprenorphine reports persistent morning withdrawal,
intense evening cravings, and recurrent fentanyl use despite adherence to the
prescribed regimen. The patient has no evidence of significant sedation or
respiratory compromise. Which is the most appropriate advanced-practice
interpretation?
A. Continued fentanyl exposure proves that buprenorphine treatment has failed and
should automatically be discontinued
B. Persistent cravings are expected and should be managed only through behavioral
therapy
C. The symptoms demonstrate that the patient is psychologically dependent on
buprenorphine and should be tapered
D. The clinician should reassess treatment adequacy, adherence, timing, exposure to
fentanyl, clinical response, and individualized dosing rather than relying on an
arbitrary dose ceiling
🔴 Correct Answer: D. The clinician should reassess treatment adequacy,
adherence, timing, exposure to fentanyl, clinical response, and individualized
dosing rather than relying on an arbitrary dose ceiling
🔵 Explanation: Treatment should be individualized according to suppression of
withdrawal and cravings, reduction of illicit opioid use, functional improvement, and
safety. Persistent symptoms warrant reassessment rather than assuming treatment
failure or psychological dependence. In the context of fentanyl exposure, induction
and maintenance can present complex clinical challenges, making individualized
evaluation particularly important.
QUESTION 5.
A patient with opioid use disorder and severe chronic pain is admitted for surgery.
