SECTION 1: OPIOID USE DISORDERS (Questions 1-36)
Question 1
Babies born to mothers who use opioids may need treatment with what?
A. Naloxone
B. Morphine or methadone
C. Buprenorphine
D. Clonidine
ANSWER✔✨-: B. Morphine or methadone
Rationale:
Option A (Naloxone): Incorrect. Naloxone is an opioid antagonist used to reverse opioid overdose, not to
treat neonatal abstinence syndrome. Using naloxone in neonates would precipitate severe withdrawal.
Option B (Morphine or methadone): Correct. Morphine is the pharmacologic treatment used most often
for neonatal abstinence syndrome

. Methadone is also used as a first-line treatment for NOWS. These opioid agonists help wean the infant
gradually from opioids.
Option C (Buprenorphine): Incorrect. While buprenorphine is being studied for NOWS treatment,
morphine remains the most commonly used first-line pharmacologic treatment

.
Option D (Clonidine): Incorrect. Clonidine may be used as an adjunctive therapy for severe withdrawal
symptoms but is not the primary treatment for neonatal abstinence syndrome.
Question 2
,Which medication can be used adjunctively to treat withdrawal seizures in neonatal opioid withdrawal?
A. Phenobarbital
B. Diazepam
C. Phenytoin
D. Lorazepam
ANSWER✔✨-: A. Phenobarbital
Rationale:
Option A (Phenobarbital): Correct. Phenobarbital can be used adjunctively to treat withdrawal seizures
and severe symptoms in neonatal abstinence syndrome when opioid monotherapy is insufficient.
Option B (Diazepam): Incorrect. While diazepam is a benzodiazepine used for alcohol withdrawal, it is
not typically the first choice for adjunctive treatment of neonatal opioid withdrawal seizures.
Option C (Phenytoin): Incorrect. Phenytoin is not effective for withdrawal seizures related to neonatal
abstinence syndrome as these are not typical epileptic seizures.
Option D (Lorazepam): Incorrect. Lorazepam is not commonly used for neonatal withdrawal seizures;
phenobarbital is the preferred adjunctive agent.
Question 3
Which neonatal withdrawal syndrome may present weeks after birth? Name the drug.
A. Heroin
B. Methadone
C. Fentanyl
D. Buprenorphine
ANSWER✔✨-: B. Methadone
Rationale:
Option A (Heroin): Incorrect. Heroin is a short-acting opioid, and withdrawal symptoms typically appear
within 24-48 hours after birth, not weeks later.
Option B (Methadone): Correct. Methadone is a long-acting opioid, and neonatal withdrawal symptoms
may be delayed and present weeks after birth due to its long half-life and accumulation in fetal tissues.
Option C (Fentanyl): Incorrect. Fentanyl is a short-acting opioid, and withdrawal typically presents within
the first few days of life.
Option D (Buprenorphine): Incorrect. While buprenorphine can cause NOWS, the onset is typically
within the first week, not weeks after birth.
,Question 4
Which medication is a safe and effective second-line treatment of symptoms refractory to opioid
therapy in newborns?
A. Phenobarbital
B. Clonidine
C. Diazepam
D. Gabapentin
ANSWER✔✨-: B. Clonidine
Rationale:
Option A (Phenobarbital): Incorrect. Phenobarbital is used as an adjunctive therapy but clonidine has
better evidence as second-line treatment.
Option B (Clonidine): Correct. Clonidine is a safe and effective second-line treatment for symptoms
refractory to opioid therapy in newborns with NOWS. It helps manage autonomic symptoms of
withdrawal.
Option C (Diazepam): Incorrect. Benzodiazepines are not typically used as second-line treatment for
NOWS.
Option D (Gabapentin): Incorrect. While gabapentin is sometimes used, clonidine has more established
evidence as second-line therapy.
Question 5
The patient must first be detoxified from opioid dependence before starting which medication?
A. Methadone
B. Buprenorphine
C. Naltrexone
D. Clonidine
ANSWER✔✨-: C. Naltrexone
Rationale:
Option A (Methadone): Incorrect. Methadone is an opioid agonist and can be started without
detoxification; it's used for maintenance treatment.
Option B (Buprenorphine): Incorrect. Buprenorphine requires the patient to be in mild-moderate
withdrawal but not fully detoxified.
Option C (Naltrexone): Correct. Naltrexone is an opioid antagonist, and patients must be fully detoxified
from opioids (typically 7-10 days) before starting to avoid precipitated withdrawal.
, Option D (Clonidine): Incorrect. Clonidine is used for withdrawal symptom management and doesn't
require detoxification first.
Question 6
Long-acting opioids, such as methadone, require at least how many hours since last use before initiating
buprenorphine?
A. 12-24 hours
B. 24-36 hours
C. 48-72 hours
D. 72-96 hours
ANSWER✔✨-: C. 48-72 hours
Rationale:
Option A (12-24 hours): Incorrect. This timeframe is insufficient for long-acting opioids and would result
in precipitated withdrawal.
Option B (24-36 hours): Incorrect. This is still too short for methadone and other long-acting opioids.
Option C (48-72 hours): Correct. Long-acting opioids like methadone require at least 48-72 hours since
last use before initiating buprenorphine to avoid precipitated withdrawal. The patient should be in mild-
to-moderate withdrawal.
Option D (72-96 hours): Incorrect. While waiting this long is safe, it's longer than necessary and may
cause unnecessary discomfort.
Question 7
Short-acting opioids (for example, heroin) require approximately how many hours since last use for
sufficient withdrawal to occur in order to safely initiate buprenorphine treatment?
A. 6-8 hours
B. 12-24 hours
C. 24-36 hours
D. 48-72 hours
ANSWER✔✨-: B. 12-24 hours
Rationale:
Option A (6-8 hours): Incorrect. This is too short; the patient may not be in sufficient withdrawal.
Option B (12-24 hours): Correct. Short-acting opioids like heroin require approximately 12-24 hours
since last use for sufficient withdrawal to occur before safely initiating buprenorphine.
