NR547 WEEK 8 EXAM QUESTIONS AND
VERIFIED CORRECT ANSWERS 2025
Substance use disorder occurs when:
the recurrent use of a substance, such as alcohol or drugs,
causes clinically significant impairment
-including health problems, disability, or failure to meet
responsibilities at home, work, or school
Tolerance
With repeated ingestion of a drug, the drug shows decreased
effect. Increasing doses are required to achieve the effects noted
with the original administration
Dependence
State of adaptation produced with repeated administration of
certain drugs so that physical symptoms occur when the drug is
discontinued abruptly.
,Addiction
A change in behavior caused by biochemical changes in the brain
after continued substance use characterized by preoccupation
with and repeated use of a substance despite of negative
outcomes.
Withdrawal
Physiological and psychological reactions that occur when the
use of a substance is stopped abruptly.
Intoxication
Condition following the ingestion of a substance resulting in
changes in level of consciousness, cognition, perception,
judgment, and behavior.
Bernita is a 64-year-old who has been using heroin for 6 years.
She is currently unemployed and lives with her daughter in the city
center. She does not have health insurance.
,prescribe the proper medication:
Methadone
Buprenorphine
Buprenorphine plus naloxone (Suboxone)
Naltrexone
Methadone
Methadone is a full μ-receptor agonist with a long half-life, which
can prevent withdrawal symptoms for 24 hours and provide
steady control of cravings throughout the day. It is only
administered in methadone federally regulated opioid treatment
programs (OTP). Methadone clinics incorporate psychosocial
interventions and require daily attendance for the first several
months, so this is a good option for a client that has the flexibility
to attend daily meetings. Use of methadone in MAT for opioid use
disorder helps extend client survival. When patients stop
methadone, they have a high likelihood of relapsing, even 10 years
after starting treatment.
Antoine is a 34-year-old who has been abusing prescription
oxycodone. He is employed but is on probation at work for
increased absenteeism. He desires MAT but is concerned about
his roommates stealing his medication to get high.
, prescribe the proper medication:
Methadone
Buprenorphine
Buprenorphine plus naloxone (Suboxone)
Naltrexone
Buprenorphine plus naloxone (Suboxone)
In combination with naloxone (Suboxone): naloxone is a mu
opioid receptor antagonist and can therefore block the effects of
buprenorphine; however, because naloxone has poor sublingual
bioavailability, it does not interfere with buprenorphine's effects
when used properly. Naloxone does have good parenteral
bioavailability; thus, if one tries to administer the
buprenorphine/naloxone formulation intravenously, naloxone will
prevent any rewarding effects from buprenorphine, making this
drug a less desirable street drug. Suboxone is a good option for a
client who may not be able to leave work for medication dosing,
as it does not need to be taken under direct observation.
Lisa is a 29-year-old who admits to using "pills, heroin, and booze"
regularly. She lives in a rural area and is employed part-time. She
has a history of poor compliance with past treatments.
