Question 1: Controlled Substance Classification
Which of the following medications are correctly classified as Schedule II controlled
substances?
A. Alprazolam and Tramadol
B. Fentanyl and Oxycodone
C. Diazepam and Codeine (<90 mg)
D. Methadone and Alprazolam
Correct Answer: B. Fentanyl and Oxycodone
Rationale: Schedule II drugs include medications with a high potential for abuse but
accepted medical use with strict regulation. Fentanyl and Oxycodone are classic
Schedule II opioids requiring tight prescribing controls. Option A and C include
Schedule III or IV drugs (alprazolam, tramadol, and low-dose codeine), while
methadone may fall under Schedule II but is inconsistently paired in options here. The
correct combination reflects high-risk opioid analgesics strictly controlled under
federal law.
Question 2: Schedule III Drugs
Which group of medications is classified under Schedule III controlled substances?
A. Alprazolam, tramadol, anabolic steroids
B. Fentanyl, morphine, oxycodone
C. Methadone and hydromorphone
D. Diazepam and lorazepam
Correct Answer: A. Alprazolam, tramadol, anabolic steroids
Rationale: Schedule III drugs have moderate to low potential for physical dependence.
Alprazolam and tramadol are common examples, along with anabolic steroids and
codeine combinations under 90 mg. Options B and C include Schedule II opioids,
which are more tightly regulated due to higher abuse potential. Benzodiazepines like
diazepam are typically Schedule IV, not III in this context.

Question 3: Schedule IV Drugs
Which of the following medications are classified as Schedule IV drugs?
A. Fentanyl and morphine
B. Alprazolam and tramadol
C. Lorazepam and Adderall
D. Oxycodone and methadone
Correct Answer: C. Lorazepam and Adderall
Rationale: Schedule IV drugs have lower abuse potential compared to Schedules II
and III. Lorazepam is a benzodiazepine, and Adderall is a stimulant, both classified as
Schedule IV. Options A and D are Schedule II opioids, while alprazolam and
tramadol are typically Schedule III or IV depending on formulation but are not the
best match here.
Question 4: Prescriptive Authority for APRNs
Which controlled substance schedules are APRNs legally permitted to prescribe
(depending on state regulations)?
A. Schedule I only
B. Schedule II through IV
C. Schedule III only
D. Schedule IV and V only
Correct Answer: B. Schedule II through IV
Rationale: Advanced Practice Registered Nurses (APRNs) are commonly authorized
to prescribe Schedule II–IV medications depending on state law and DEA registration.
Schedule I drugs have no accepted medical use and cannot be prescribed. This
authority allows APRNs to manage moderate to severe pain while maintaining
regulatory safeguards.
Question 5: Medication Non-Adherence
Which of the following is NOT a common reason for medication non-adherence?
A. Forgetting doses
B. Cost of medication
C. Traveling and being busy
D. Increased liver enzyme activity
Correct Answer: D. Increased liver enzyme activity
, 2026/2027
Rationale: Non-adherence is commonly due to practical and behavioral factors such
as forgetting, cost, or lifestyle disruptions. Physiological changes like liver enzyme
activity affect drug metabolism but are not a behavioral cause of non-adherence. Thus,
option D is the exception.
Question 6: Pharmacokinetics in the Elderly
Which physiological change in older adults most affects drug distribution?
A. Increased renal clearance
B. Increased gastric acidity
C. Decreased albumin and lean body mass
D. Increased hepatic enzyme production
Correct Answer: C. Decreased albumin and lean body mass
Rationale: Aging reduces albumin and lean muscle mass, altering drug binding and
distribution. This increases free drug concentration and risk of toxicity. Other options
are incorrect because gastric acidity decreases, renal clearance declines, and hepatic
enzymes typically decrease with age.
Question 7: Liver Function and Aging
Why does hepatic drug metabolism decrease in older adults?
A. Increased liver size
B. Increased bile production
C. Decreased hepatic blood flow and enzyme activity
D. Increased protein binding
Correct Answer: C. Decreased hepatic blood flow and enzyme activity
Rationale: Aging reduces liver perfusion and enzyme activity, slowing drug
metabolism and increasing drug half-life. This increases risk of accumulation and
toxicity, especially with drugs requiring hepatic clearance.
Question 8: Adverse Drug Reaction Causes
What is the most important cause of adverse drug reactions in clinical practice?
A. Underprescribing
B. Polypharmacy and overprescribing
C. Low drug dosages
D. Patient hydration status
Correct Answer: B. Polypharmacy and overprescribing
