SPECIAL POPULATIONS (25 Questions)
Q1. A 68-year-old patient with atrial fibrillation is started on warfarin. The nurse
practitioner knows that genetic testing for which enzyme is most relevant for
determining initial warfarin dosing?
A. CYP3A4
B. CYP2D6
C. CYP2C9 and VKORC1
D. CYP2C19 and SLCO1B1
Rationale: For the NR 566 final exam, remember that warfarin metabolism involves both
CYP2C9 (which metabolizes S-warfarin) and VKORC1 (the target enzyme). Genetic
variants in these two genes account for about 40% of dosing variability, and the FDA
actually includes pharmacogenomic dosing tables on the warfarin label. That's correct
because in family practice, knowing your patient's CYP2C9 and VKORC1 status helps
you avoid bleeding complications from overdosing or thrombotic events from
underdosing.
Correct Answer: C
,Q2. A 45-year-old patient with depression is prescribed fluoxetine. Two weeks later, the
patient needs tramadol for post-operative pain. What is the primary concern with this
combination?
A. Increased risk of gastrointestinal bleeding
B. Serotonin syndrome
C. Enhanced opioid analgesia
D. Reduced tramadol efficacy
Rationale: The best choice is serotonin syndrome. Fluoxetine is a potent SSRI, and
tramadol has SNRI properties plus weak opioid activity—together they significantly
increase serotonin levels. For the NR 566 final, always flag this combination. A common
final exam trap is confusing tramadol's opioid effects with its serotonergic
properties—the key difference is that tramadol is NOT just an opioid; it inhibits serotonin
and norepinephrine reuptake, making it dangerous with SSRIs.
Correct Answer: B
Q3. Which of the following is a Phase II metabolic reaction?
A. Oxidation
B. Reduction
C. Hydrolysis
D. Glucuronidation
,Rationale: That's correct because glucuronidation is a conjugation reaction, which
defines Phase II metabolism. In family practice, remember that Phase I reactions
(oxidation, reduction, hydrolysis) create or expose functional groups, while Phase II
conjugates these with endogenous compounds to make drugs water-soluble for renal
excretion. This aligns with current pharmacology principles tested on the NR 566 final.
Correct Answer: D
Q4. A pregnant patient in her first trimester presents with hyperthyroidism. Which
antithyroid medication is preferred during this period?
A. Methimazole
B. Propylthiouracil (PTU)
C. Radioactive iodine
D. Propranolol
Rationale: The best choice is PTU. For the NR 566 final exam, remember that
methimazole is associated with aplasia cutis and choanal atresia in the first trimester,
making PTU the preferred agent during weeks 1-12. After the first trimester, you switch
to methimazole because PTU carries a higher risk of hepatotoxicity. This is a classic
pregnancy pharmacology question that shows up on every Chamberlain final.
Correct Answer: B
Q5. A breastfeeding mother asks which antidepressant is safest while nursing. Based
on LactMed and Hale's categories, which is the preferred choice?
A. Paroxetine
, B. Fluoxetine
C. Sertraline
D. Venlafaxine
Rationale: That's correct because sertraline is the preferred SSRI in lactation. For the NR
566 final, remember that sertraline has the lowest relative infant dose among SSRIs and
is classified as Hale's L2 (safer). Fluoxetine has a long half-life and higher infant
exposure (L3), while paroxetine, though also L2, has more withdrawal concerns in
infants. This aligns with current guidelines for prescribing in breastfeeding women.
Correct Answer: C
Q6. An 82-year-old patient with a CrCl of 28 mL/min is prescribed gabapentin for
neuropathic pain. What adjustment is needed?
A. No adjustment needed; gabapentin is hepatically metabolized
B. Reduce the dose and extend the dosing interval
C. Switch to pregabalin instead
D. Avoid gabapentin entirely in elderly patients
Rationale: The best choice is reducing the dose and extending the dosing interval.
Gabapentin is renally excreted unchanged, so in older adults with reduced renal
function, you must calculate CrCl using Cockcroft-Gault and adjust accordingly. A
common final exam trap is thinking gabapentin needs hepatic dosing—it's actually
almost entirely eliminated by the kidneys, making renal function critical for safe
prescribing.
