1. A 34-year-old female at 28 weeks gestation presents with worsening hypertension. Her blood
pressure is 158/98 mmHg. She is currently on labetalol 200mg BID. Which of the following is
the most appropriate adjustment to her pharmacotherapy, considering both maternal control and
fetal safety?
A. Initiate lisinopril 10mg daily to improve target organ protection.
B. Increase labetalol dosage to 300mg TID and monitor fetal heart rate.
C. Add hydrochlorothiazide to enhance volume depletion.
D. Switch to amlodipine monotherapy to reduce potential fetal bradycardia.
Answer: B
, Rationale: Labetalol is a first-line agent for gestational hypertension. Increasing the dose is
safer than introducing ACE inhibitors, which are contraindicated in pregnancy due to risk of
fetal renal dysplasia. Diuretics are generally avoided in preeclampsia/gestational hypertension
due to reduced plasma volume. B is correct as it optimizes current therapy; A, C, and D are
either contraindicated or less effective in this clinical scenario.
CORRECT ANSWER : B
2. A 68-year-old patient with history of heart failure and osteoporosis is prescribed a new
medication regimen. Which pharmacokinetic change most significantly alters drug metabolism
in this patient population?
A. Increased first-pass metabolism due to hepatic enzyme induction.
B. Enhanced renal tubular secretion of weak acids.
C. Decreased total body water and lean body mass, impacting volume of distribution.
D. Faster gastric emptying leading to rapid absorption of enteric-coated tablets.
Answer: C
Rationale: Aging leads to physiologic changes including reduced total body water and decreased
lean muscle mass, which alter the volume of distribution for hydrophilic and lipophilic drugs. A
is incorrect as hepatic function generally declines; B is incorrect as renal clearance decreases;
D is incorrect as gastric emptying typically slows in the elderly.
CORRECT ANSWER : C
3. A 42-year-old patient presents with symptoms of polycystic ovary syndrome (PCOS). She
desires cycle regulation and has no contraindications to hormonal therapy. Which mechanism of
action represents the rationale for using combined oral contraceptives (COCs) in this patient?
A. Direct stimulation of ovarian follicular development.
B. Suppression of luteinizing hormone (LH) and decreased ovarian androgen production.
C. Inhibition of hepatic sex hormone-binding globulin (SHBG) synthesis.
D. Direct peripheral antagonism of androgen receptors.
Answer: B
Rationale: COCs suppress LH secretion from the pituitary, which reduces ovarian androgen
production. A is incorrect as this would worsen the condition. C is incorrect because COCs
, actually increase SHBG, reducing free testosterone. D is incorrect as COCs do not function as
direct androgen receptor antagonists.
CORRECT ANSWER : B
4. When initiating hormone replacement therapy (HRT) for a 52-year-old menopausal patient with
an intact uterus, why is the addition of a progestogen mandatory?
A. To prevent the development of breast malignancy.
B. To mitigate the risk of endometrial hyperplasia and carcinoma.
C. To prevent cardiovascular events and lipid oxidation.
D. To suppress FSH/LH levels more effectively than estrogen alone.
Answer: B
Rationale: Unopposed estrogen therapy in a patient with a uterus significantly increases the risk
of endometrial hyperplasia and adenocarcinoma. Progestogens are required to induce secretory
changes in the endometrium to prevent this proliferation. A, C, and D are not the primary
clinical rationale for the mandatory addition of progestogen in this patient.
CORRECT ANSWER : B
5. A 12-year-old patient requires long-term corticosteroid therapy. Which monitoring parameter is
most critical to evaluate for long-term adverse effects on bone health?
A. Serum vitamin D levels only.
B. Bone mineral density (BMD) via DXA and assessment of growth velocity.
C. Daily caloric intake and protein consumption.
D. Baseline echocardiogram and lipid profile.
Answer: B
Rationale: Long-term corticosteroids interfere with bone remodeling and can cause growth
retardation in pediatric patients. Assessing growth velocity and BMD is the standard of care for
monitoring these specific physiological risks. A, C, and D are important for overall health but do
not directly address the primary risk of bone resorption and growth suppression.
CORRECT ANSWER : B
, 6. An 80-year-old patient on polypharmacy for hypertension, GERD, and insomnia presents with
new-onset confusion. Which medication class is most likely responsible, according to the Beers
Criteria?
A. Proton pump inhibitors (PPIs).
B. First-generation antihistamines (e.g., diphenhydramine).
C. Angiotensin receptor blockers (ARBs).
D. SSRI antidepressants.
Answer: B
Rationale: First-generation antihistamines are anticholinergic and highly sedating, posing a
high risk for cognitive impairment and delirium in the elderly. PPIs, ARBs, and SSRIs have
different risk profiles, though they require monitoring, they are not the primary suspects for
acute confusion compared to anticholinergics.
CORRECT ANSWER : B
7. A patient is prescribed warfarin for atrial fibrillation. When instructing on medication safety,
which interaction must the patient avoid to prevent therapeutic failure?
A. High intake of vitamin K-rich foods like kale and spinach.
B. Concurrent use of acetaminophen.
C. Moderate intake of caffeine.
D. Use of H2 receptor antagonists.
Answer: A
Rationale: Vitamin K is the antagonist to warfarin; fluctuating intake of vitamin K-rich foods
alters the INR and renders the anticoagulant effect unpredictable. B, C, and D may interact, but
the fluctuation of vitamin K is the most significant and clinically common cause of therapeutic
failure.
CORRECT ANSWER : A
8. In treating a patient with hypothyroidism, which factor is most likely to decrease the absorption
of levothyroxine?
A. High fiber diet.
