1. A 45-year-old female presents to the clinic with complaints of fatigue, weight gain, constipation,
and cold intolerance over the past three months. Laboratory evaluation reveals a TSH of 12.5
mIU/L (reference: 0.4-4.0 mIU/L) and a free T4 of 0.7 ng/dL (reference: 0.8-1.8 ng/dL). She has
a past medical history significant for coronary artery disease. Which of the following is the most
appropriate initial management strategy for this patient?
A. Initiate levothyroxine at a full replacement dose of 1.6 mcg/kg/day orally once daily.
B. Initiate levothyroxine at a low dose of 25 to 50 mcg orally once daily.
C. Initiate triiodothyronine (T3) monotherapy to bypass peripheral conversion issues.
D. Monitor thyroid function every 4 weeks without pharmacological intervention until TSH
exceeds 20 mIU/L.
CORRECT ANSWER : B
Rationale: In patients with primary hypothyroidism and underlying cardiovascular disease,
initiating levothyroxine at a full replacement dose can precipitate myocardial ischemia, angina,
or acute heart failure due to an abrupt increase in myocardial oxygen demand. Therefore, a
conservative starting dose of 25 to 50 mcg daily is indicated, with gradual upward titration
based on clinical response and repeat TSH levels. Option A is incorrect because full-dose
replacement is reserved for younger, healthy patients. Option C is incorrect because T3
monotherapy is not recommended for routine hypothyroidism management due to rapid
absorption and peak fluctuations. Option D is incorrect because symptomatic primary
hypothyroidism with a TSH of 12.5 requires treatment rather than surveillance alone.
2. A 62-year-old male with a history of type 2 diabetes mellitus, hypertension, and stage 3 chronic
kidney disease (eGFR 45 mL/min/1.73 $m^2$, UACR 150 mg/g) presents for routine follow-up.
His current medications include metformin and lisinopril. His HbA1c is 8.2%. Which of the
following additional agents provides the greatest cardiorenal risk reduction for this patient?
A. A sulfonylurea such as glipizide
B. A dipeptidyl peptidase-4 (DPP-4) inhibitor such as sitagliptin
, C. A sodium-glucose cotransporter 2 (SGLT2) inhibitor such as empagliflozin
D. A long-acting basal insulin analog such as glargine
CORRECT ANSWER : C
Rationale: SGLT2 inhibitors demonstrate robust, evidence-based cardiorenal benefits, including
slowing the progression of chronic kidney disease and reducing heart failure hospitalizations in
patients with diabetic kidney disease and albuminuria, independent of glycemic control. Option
A (sulfonylureas) increases the risk of hypoglycemia and lacks cardiorenal protective benefits.
Option B (DPP-4 inhibitors) is weight-neutral and does not offer significant cardiovascular or
renal protection. Option D (insulin) effectively lowers blood glucose but does not provide
specific kidney or heart failure risk reduction compared to SGLT2 inhibitors.
3. A 28-year-old G2P1001 at 28 weeks gestation presents for a routine prenatal visit. Her screening
laboratory results show a hemoglobin of 10.1 g/dL, hematocrit of 31%, mean corpuscular
volume (MCV) of 72 fL, and serum ferritin of 12 ng/mL. Which of the following is the most
appropriate diagnosis and initial intervention?
A. Physiologic anemia of pregnancy; reassurance and continued prenatal vitamins.
B. Iron deficiency anemia; initiate oral elemental iron supplementation.
C. Beta-thalassemia minor; order hemoglobin electrophoresis and genetic counseling.
D. Folate deficiency anemia; initiate daily folic acid supplementation of 5 mg.
CORRECT ANSWER : B
Rationale: The patient exhibits microcytic anemia (MCV < 80 fL) accompanied by a low serum
ferritin level (< 30 ng/mL), which is diagnostic for iron deficiency anemia. Oral elemental iron
supplementation is the first-line treatment during pregnancy to replenish iron stores and support
expanded maternal-fetal erythropoiesis. Option A is incorrect because although mild anemia can
occur due to plasma volume expansion, microcytosis and low ferritin reflect true iron deficiency
requiring treatment. Option C is less likely given the low ferritin level, which points directly to
iron deficiency rather than a hemoglobinopathy. Option D is incorrect because folate deficiency
typically results in macrocytic anemia.
4. A 54-year-old male presents with acute, severe pain, swelling, and erythema of the first
metatarsophalangeal joint of his right foot, which began abruptly overnight. Arthrocentesis of the
joint fluid reveals needle-shaped, negatively birefringent crystals under polarized light
microscopy, along with a high white blood cell count predominantly composed of neutrophils.
Which of the following is the preferred first-line pharmacological treatment for an acute attack in
this patient with no history of renal impairment?
A. Allopurinol initiated at 300 mg daily
, B. Indomethacin or another nonsteroidal anti-inflammatory drug (NSAID)
C. Probenecid at 500 mg twice daily
D. Intravenous administration of high-dose corticosteroids
CORRECT ANSWER : B
Rationale: The clinical presentation and synovial fluid analysis confirm an acute flare of gout.
First-line therapy for acute gout attacks includes nonsteroidal anti-inflammatory drugs
(NSAIDs), colchicine, or corticosteroids to rapidly suppress inflammation. Option A is incorrect
because urate-lowering therapy (such as allopurinol) should not be initiated during an acute
attack as it can cause sudden shifts in serum urate levels and paradoxically prolong or
exacerbate the flare. Option C is a uricosuric agent not used for acute inflammation
management. Option D is typically reserved for patients with contraindications to NSAIDs or
colchicine, such as severe renal disease.
5. A 70-year-old female presents with insidious onset of memory impairment, word-finding
difficulty, and personality changes over the past two years, which are progressively interfering
with her ability to manage her finances and medications. Neurological examination is non-focal,
and Montreal Cognitive Assessment (MoCA) score is 18/30. Neuroimaging rules out secondary
causes. Which of the following is the most appropriate initial pharmacological therapy?
A. Memantine, an N-methyl-D-aspartate (NMDA) receptor antagonist
B. Donepezil, an acetylcholinesterase inhibitor
C. Haloperidol, a high-potency typical antipsychotic
D. Estrogen hormone replacement therapy
CORRECT ANSWER : B
Rationale: The patient exhibits classic clinical features of mild-to-moderate Alzheimer's
dementia. First-line pharmacotherapy for cognitive symptoms consists of cholinesterase
inhibitors, such as donepezil, rivastigmine, or galantamine, which help improve cholinergic
neurotransmission. Option A (memantine) is typically indicated for moderate-to-severe
Alzheimer's disease, often used adjunctively with a cholinesterase inhibitor later in the disease
course. Option C (haloperidol) is contraindicated as first-line for baseline cognitive symptoms
due to the severe risk of accelerated cognitive decline, extrapyramidal symptoms, and mortality
in elderly dementia patients. Option D (estrogen) has no proven efficacy in treating established
dementia and carries significant health risks.
6. A 35-year-old female presents with episodic palpitations, diaphoresis, tremors, and a sense of
impending doom that peak within 10 minutes and resolve within half an hour. These episodes
occur unpredictably and have led to significant anticipatory anxiety and behavioral changes
, regarding leaving her home. Physical examination and baseline workup, including an ECG and
TSH, are normal. Which of the following is the most effective combined treatment approach?
A. Cognitive Behavioral Therapy (CBT) and a Selective Serotonin Reuptake Inhibitor
(SSRI)
B. Long-term treatment with high-dose alprazolam monotherapy
C. Atypical antipsychotic monotherapy with quetiapine
D. Interpersonal psychotherapy combined with regular physical exercise
CORRECT ANSWER : A
Rationale: The patient meets the diagnostic criteria for panic disorder. The gold-standard,
evidence-based management involves a combination of Cognitive Behavioral Therapy (CBT) and
pharmacotherapy with a Selective Serotonin Reuptake Inhibitor (SSRI). Option B is incorrect
because long-term benzodiazepine use is discouraged due to risks of tolerance, dependence, and
withdrawal. Option C is incorrect as atypical antipsychotics are not first-line treatments for
panic disorder. Option D lacks the specific targeted efficacy of CBT and SSRIs for panic
disorder symptoms.
7. A 50-year-old male with a 30 pack-year smoking history presents with a 3-month history of a
chronic, productive cough, dyspnea on exertion, and recurrent lower respiratory tract infections.
Spirometry demonstrates a post-bronchodilator $FEV_1/FVC$ ratio of 0.65 and an $FEV_1$ of
55% of predicted. According to global initiative guidelines, which classification category best
describes this patient's chronic obstructive pulmonary disease (COPD)?
A. GOLD 1 (Mild)
B. GOLD 2 (Moderate)
C. GOLD 3 (Severe)
D. GOLD 4 (Very Severe)
CORRECT ANSWER : B
Rationale: COPD severity is classified via post-bronchodilator spirometry based on the
$FEV_1$ percentage of predicted value when the $FEV_1/FVC$ ratio is less than 0.70. GOLD 2
(Moderate) is defined as an $FEV_1$ between 50% and 79% of predicted. GOLD 1 is 80% or
greater, GOLD 3 is 30% to 49%, and GOLD 4 is less than 30% of predicted.
8. A 19-year-old college student presents with a 4-day history of sore throat, profound fatigue, low-
grade fever, and posterior cervical lymphadenopathy. Physical examination reveals enlarged,
