Question 1: A 62-year-old male with a past medical history significant for type 2 diabetes mellitus,
hypertension, and hyperlipidemia presents to the primary care clinic complaining of progressive
bilateral lower extremity edema and shortness of breath on exertion over the past two weeks. He
reports needing to sleep on three pillows at night to avoid waking up gasping for air. On physical
examination, his blood pressure is 158/92 mmHg, heart rate is 88 bpm, and oxygen saturation is 93%
on room air. Auscultation of the heart reveals an S3 gallop, and lung fields demonstrate bilateral
basilar crackles. Which of the following diagnostic tests is most appropriate to confirm the suspected
underlying etiology of this patient's acute presentation?
A. Computed tomography pulmonary angiography B. Transthoracic echocardiogram C. Right heart
catheterization D. Ventilation-perfusion scan
CORRECT ANSWER: B. Transthoracic echocardiogram
Rationale: The patient's clinical presentation of progressive dyspnea on exertion, orthopnea, paroxysmal
nocturnal dyspnea, lower extremity edema, an S3 gallop, and pulmonary crackles is highly indicative of
acute decompensated heart failure. A transthoracic echocardiogram is the most appropriate initial
diagnostic test to evaluate left ventricular systolic and diastolic function, assess valvular structure and
function, and confirm the diagnosis of heart failure. Computed tomography pulmonary angiography and
ventilation-perfusion scans are utilized to diagnose pulmonary embolism, which does not typically
,present with an S3 gallop. Right heart catheterization is an invasive procedure reserved for specific cases
of heart failure when non-invasive testing is inconclusive or when assessing for pulmonary hypertension.
Question 2: A 28-year-old female at 24 weeks gestation presents to the clinic complaining of a severe,
throbbing headache that is unilateral and associated with nausea, vomiting, and photophobia. She
reports that she has a history of similar headaches prior to her pregnancy, but they have increased in
frequency and severity over the past month. Her blood pressure is 118/76 mmHg, and a review of
systems is otherwise unremarkable. Urinalysis shows no proteinuria. Which of the following
pharmacological agents is considered the safest and most effective first-line abortive therapy for this
patient's acute symptoms?
A. Sumatriptan B. Ergotamine C. Acetaminophen D. Ibuprofen
CORRECT ANSWER: C. Acetaminophen
Rationale: The patient is experiencing acute migraine headaches during her second trimester of
pregnancy. Acetaminophen is considered the safest first-line abortive analgesic for mild to moderate
migraines during all trimesters of pregnancy. Sumatriptan may be considered in severe, refractory cases
after a careful risk-benefit analysis, but it is not first-line. Ergotamine is strictly contraindicated in
pregnancy due to its uterotonic effects and potential to cause fetal harm. Ibuprofen and other
nonsteroidal anti-inflammatory drugs (NSAIDs) are generally avoided, particularly in the third trimester,
due to the risk of premature closure of the fetal ductus arteriosus and oligohydramnios.
Question 3: A 45-year-old female presents to the clinic with a chief complaint of persistent fatigue,
weight gain, and cold intolerance over the past three months. She also reports dry skin and occasional
constipation. On physical examination, she has a delayed relaxation phase of her deep tendon
reflexes and a slightly enlarged, non-tender thyroid gland. Laboratory results reveal a serum thyroid-
stimulating hormone (TSH) level of 12.5 mIU/L and a free thyroxine (T4) level of 0.6 ng/dL. Which of
the following is the most likely etiology of this patient's thyroid dysfunction?
A. Graves' disease B. Hashimoto's thyroiditis C. Subacute granulomatous thyroiditis D. Toxic
multinodular goiter
CORRECT ANSWER: B. Hashimoto's thyroiditis
Rationale: The patient's clinical symptoms of fatigue, weight gain, cold intolerance, dry skin, and
constipation, combined with a delayed relaxation phase of deep tendon reflexes, are classic signs of
hypothyroidism. The elevated TSH and low free T4 confirm primary hypothyroidism. Hashimoto's
thyroiditis, an autoimmune condition characterized by the presence of anti-thyroid peroxidase (anti-
TPO) antibodies, is the most common cause of primary hypothyroidism in iodine-sufficient regions.
Graves' disease and toxic multinodular goiter cause hyperthyroidism. Subacute granulomatous
thyroiditis typically presents with a painful, tender thyroid gland following a viral illness and often
features a transient hyperthyroid phase before becoming hypothyroid.
Question 4: A 55-year-old male with a 30-pack-year smoking history presents to the clinic complaining
of a chronic, productive cough that has worsened over the past six months. He reports bringing up
thick, white sputum most mornings. He denies any fever, hemoptysis, or unintended weight loss. On
physical examination, his oxygen saturation is 94% on room air, and auscultation reveals scattered
,rhonchi that clear with coughing. Spirometry demonstrates a forced expiratory volume in one second
(FEV1) to forced vital capacity (FVC) ratio of 0.65. Which of the following is the most appropriate
initial pharmacological management for this patient?
A. Inhaled short-acting beta-agonist as needed B. Inhaled long-acting muscarinic antagonist daily C. Oral
systemic corticosteroids daily D. Inhaled corticosteroid and long-acting beta-agonist combination daily
CORRECT ANSWER: B. Inhaled long-acting muscarinic antagonist daily
Rationale: The patient's clinical presentation of chronic productive cough, significant smoking history,
and spirometry showing a post-bronchodilator FEV1/FVC ratio less than 0.70 confirms a diagnosis of
chronic obstructive pulmonary disease (COPD), specifically the chronic bronchitis phenotype. According
to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, initial pharmacological
treatment for Group A or B COPD patients typically involves a long-acting bronchodilator, such as a long-
acting muscarinic antagonist (LAMA) or a long-acting beta-agonist (LABA). Inhaled corticosteroids are
not recommended as initial monotherapy and are generally reserved for patients with frequent
exacerbations or elevated eosinophil counts. Oral systemic corticosteroids are used for acute
exacerbations, not chronic maintenance.
Question 5: A 32-year-old female presents to the clinic complaining of a two-week history of a painful,
vesicular rash on her left lower back that wraps around to her anterior abdomen. She reports a
burning, tingling pain in the area that preceded the rash by three days. On physical examination, there
is a unilateral, erythematous, maculopapular and vesicular rash in a dermatomal distribution (T10)
that does not cross the midline. She has no history of immunosuppression and is currently taking no
medications. Which of the following is the most appropriate pharmacological treatment for this
patient?
A. Oral valacyclovir B. Topical acyclovir C. Oral amoxicillin-clavulanate D. Topical clotrimazole
CORRECT ANSWER: A. Oral valacyclovir
Rationale: The patient's clinical presentation of a painful, unilateral, vesicular rash in a dermatomal
distribution is classic for herpes zoster (shingles), which is caused by the reactivation of the varicella-
zoster virus. Oral antiviral therapy, such as valacyclovir, famciclovir, or acyclovir, is the standard of care
and should be initiated within 72 hours of rash onset to reduce the severity and duration of the rash and
the risk of postherpetic neuralgia. Topical acyclovir is not effective for herpes zoster. Amoxicillin-
clavulanate is an antibacterial agent and would not treat a viral infection. Clotrimazole is an antifungal
agent used for dermatophyte infections, which do not present in a dermatomal distribution.
Question 6: A 68-year-old male with a history of osteoarthritis presents to the clinic complaining of
progressive bilateral knee pain that is worse with weight-bearing activities and improves with rest. He
reports morning stiffness that typically lasts for less than 30 minutes. On physical examination, there
is crepitus with range of motion of both knees, mild joint line tenderness, and no significant effusion
or erythema. Radiographs of the knees demonstrate joint space narrowing, subchondral sclerosis, and
osteophyte formation. Which of the following non-pharmacological interventions is considered a core
recommendation in the initial management of this patient's condition?
, A. Strict bed rest for two weeks B. Weight loss and low-impact aerobic exercise C. High-impact aerobics
and weightlifting D. Immobilization with a knee brace continuously
CORRECT ANSWER: B. Weight loss and low-impact aerobic exercise
Rationale: The patient's clinical presentation and radiographic findings are classic for osteoarthritis of
the knees. Core non-pharmacological recommendations for the management of osteoarthritis include
patient education, weight loss (if overweight or obese), and low-impact aerobic exercise, such as
swimming or cycling, to improve joint function and reduce pain. Strict bed rest and continuous
immobilization can lead to muscle atrophy and joint stiffness, worsening the condition. High-impact
aerobics and heavy weightlifting can exacerbate joint pain and accelerate cartilage degradation.
Question 7: A 24-year-old female presents to the clinic complaining of a three-day history of dysuria,
urinary frequency, and urgency. She denies any flank pain, fever, chills, or vaginal discharge. On
physical examination, her vital signs are within normal limits, and there is no costovertebral angle
tenderness. Urinalysis is positive for leukocyte esterase and nitrites, and microscopy reveals
numerous white blood cells and bacteria. Which of the following is the most appropriate first-line
empirical antibiotic therapy for this patient?
A. Oral ciprofloxacin B. Oral nitrofurantoin C. Intravenous ceftriaxone D. Oral azithromycin
CORRECT ANSWER: B. Oral nitrofurantoin
Rationale: The patient's clinical presentation of dysuria, frequency, and urgency, combined with a
urinalysis positive for leukocyte esterase and nitrites, is highly suggestive of uncomplicated acute cystitis
(lower urinary tract infection). According to the Infectious Diseases Society of America (IDSA) guidelines,
first-line empirical antibiotic therapy for uncomplicated cystitis in women includes nitrofurantoin,
trimethoprim-sulfamethoxazole, or fosfomycin. Fluoroquinolones like ciprofloxacin are highly effective
but are reserved as alternative agents due to concerns about collateral damage and adverse effects.
Intravenous ceftriaxone is used for severe infections or pyelonephritis. Azithromycin is used for
chlamydia, which typically presents with cervicitis rather than acute cystitis.
Question 8: A 50-year-old male with a history of alcohol use disorder presents to the emergency
department with confusion, ataxia, and ophthalmoplegia. His family reports that he has been drinking
heavily for the past week and has barely eaten. On physical examination, he is lethargic but
arousable, has bilateral lateral rectus palsies, and exhibits a wide-based, unsteady gait. His blood
glucose level is 85 mg/dL. Which of the following is the most critical immediate intervention for this
patient?
A. Intravenous haloperidol B. Intravenous thiamine C. Intravenous flumazenil D. Intravenous naloxone
CORRECT ANSWER: B. Intravenous thiamine
Rationale: The patient's clinical triad of confusion, ataxia, and ophthalmoplegia in the context of chronic
alcohol use and poor nutrition is classic for Wernicke's encephalopathy, a neurological emergency
caused by severe thiamine (vitamin B1) deficiency. The most critical immediate intervention is the
administration of intravenous thiamine to prevent permanent neurological damage, such as Korsakoff's
syndrome. It is crucial to administer thiamine before or concurrently with glucose, as glucose
metabolism can rapidly deplete remaining thiamine stores and precipitate or worsen Wernicke's
