Q1 – Q10

Question 1 of 50
,2
A 67-year-old woman with chronic kidney disease (eGFR 28 mL/min) is
prescribed oral morphine for severe osteoarthritis pain. She reports
feeling "very groggy and confused" after just two doses at the standard
starting dose. Which pharmacokinetic principle best explains her
exaggerated response?
A. Decreased first-pass metabolism due to hepatic congestion
B. Reduced renal clearance leading to accumulation of morphine
metabolites
C. Enhanced gastrointestinal absorption in the elderly population
D. Increased volume of distribution from hypoalbuminemia ✓
CORRECT
Correct Answer: B
Rationale: Morphine and its active metabolite morphine-6-glucuronide
are primarily eliminated renally, so reduced kidney function causes
metabolite accumulation and prolonged opioid effects including sedation
and confusion. While increased volume of distribution can affect some
drugs, it does not specifically explain the exaggerated CNS effects seen
with opioids in renal impairment.
Question 2 of 50
A 54-year-old man with atrial fibrillation is started on warfarin. His INR
has been stable at 2.5 for three months. He presents today after starting
an over-the-counter supplement his neighbor recommended for "joint
,3
health," and his INR is now 4.1. Which mechanism most likely accounts
for this interaction?
A. Induction of CYP2C9, accelerating warfarin metabolism
B. Competitive protein binding displacement of warfarin from albumin
C. Inhibition of CYP2C9, reducing warfarin metabolic clearance ✓
CORRECT
D. Enhanced renal tubular reabsorption of warfarin
Correct Answer: C
Rationale: Many herbal supplements, particularly those containing
curcumin or high-dose vitamin E, can inhibit CYP2C9, the primary
enzyme responsible for metabolizing S-warfarin, the more potent
enantiomer. Protein binding displacement typically produces transient
INR elevations rather than sustained changes, and CYP induction would
decrease—not increase—the INR.
Question 3 of 50
A 28-year-old woman with newly diagnosed generalized anxiety
disorder is prescribed escitalopram 10 mg daily. At her 4-week follow-
up, she states she hasn't noticed any improvement and wants to
discontinue the medication. What is the most appropriate response
regarding the expected timeline for therapeutic effect?
, 4
A. Full therapeutic benefit should be evident within 5–7 days of
consistent dosing
B. Anxiolytic effects typically emerge after 2–4 weeks due to
downstream neuroadaptive changes ✓ CORRECT
C. If no response by week 4, the medication is ineffective and should be
changed immediately
D. Therapeutic delay is caused by slow gastrointestinal absorption of
SSRI molecules
Correct Answer: B
Rationale: SSRIs require 2–4 weeks (sometimes longer) for therapeutic
effect because their antidepressant and anxiolytic actions depend on
neuroplastic changes, receptor downregulation, and increased BDNF
expression—not immediate synaptic serotonin increases. The medication
should generally be given 6–8 weeks at a therapeutic dose before being
deemed a treatment failure, and absorption rate does not explain this
delayed onset.
Question 4 of 50
An 8-month-old infant weighing 8 kg is brought to the pediatric clinic
with otitis media and is prescribed amoxicillin 80 mg/kg/day divided
every 8 hours. Compared to an adult receiving the same antibiotic,
which pharmacokinetic parameter will be most significantly different in
this infant?
A. Protein binding capacity of amoxicillin to plasma albumin
