1. A 42-year-old female presents to the primary care clinic reporting a 3-month history of
fatigue, weight gain of 15 pounds, constipation, and cold intolerance. Her physical exam
reveals dry skin, delayed relaxation of deep tendon reflexes, and a heart rate of 54 beats
per minute. Laboratory evaluation demonstrates an elevated TSH and a low free T4.
Which of the following is the most appropriate initial pharmacological management?
A. Methimazole 10 mg orally daily
B. Levothyroxine 1.6 mcg/kg orally once daily
C. Liothyronine 25 mcg orally twice daily
D. Propylthiouracil 100 mg orally three times daily
Answer: B
Primary hypothyroidism is characterized by elevated TSH and low free T4, requiring thyroid
hormone replacement therapy; levothyroxine is the synthetic T4 of choice, dosed by weight or
starting at 25 to 50 mcg daily in older adults or those with cardiac disease, titrated every 4 to 6
weeks.
2. A 35-year-old male comes to the urgent care clinic complaining of a 2-day history of
severe, sharp right-sided chest pain that worsens with deep inspiration and coughing,
accompanied by mild dyspnea. He reports a long-haul airplane flight 4 days ago. His vital
signs are: BP 128/82, HR 108, RR 22, SpO2 93% on room air. An electrocardiogram shows
sinus tachycardia with no ST-segment elevations. What is the most appropriate next step in
clinical management?
A. Order a D-dimer blood test or a computed tomography pulmonary angiography (CTPA)
based on pretest probability
B. Prescribe a 7-day course of oral amoxicillin-clavulanate for acute bronchitis
C. Instruct the patient on incentive spirometry and discharge home with analgesics
D. Administer sublingual nitroglycerin and observe for 30 minutes
Answer: A
,This patient presents with classic signs of a pulmonary embolism (tachycardia, tachypnea,
pleuritic chest pain, and recent prolonged immobility); assessment using a validated clinical
decision rule (Wells score) coupled with D-dimer or diagnostic imaging (CTPA) is mandatory.
3. A nurse practitioner is evaluating a 55-year-old male with a 30 pack-year smoking
history who presents with a persistent cough, hemoptysis, and a 12-pound unintentional
weight loss over 2 months. A chest radiograph reveals a central hilar mass and mediastinal
widening. Which of the following diagnostic modalities is indicated next for definitive tissue
diagnosis and staging?
A. Repeat chest X-ray in 6 months
B. Bronchoscopy with biopsy and contrast-enhanced chest/upper abdomen CT scan
C. Serial sputum cytology alone for 3 consecutive mornings
D. Empiric treatment with a broad-spectrum fluoroquinolone
Answer: B
A central hilar mass with hemoptysis and weight loss strongly suggests bronchogenic
carcinoma; definitive diagnosis requires tissue acquisition via bronchoscopy or needle biopsy,
alongside staging CT scans of the chest and abdomen.
4. A 68-year-old female with a history of long-standing hypertension and type 2 diabetes
presents for a routine physical examination. Her blood pressure is 142/88 mmHg. She is
currently taking lisinopril 20 mg daily. According to current evidence-based guidelines,
which of the following is the most appropriate adjustment to her pharmacological
regimen?
A. Discontinue lisinopril and initiate a beta-blocker as monotherapy
B. Add a calcium channel blocker or thiazide-like diuretic to her current ACE inhibitor therapy
C. Double the dose of lisinopril to 40 mg daily
D. Advise lifestyle modifications exclusively without medication changes for 12 months
Answer: B
Combination therapy utilizing agents with complementary mechanisms (such as an ACE
inhibitor combined with a dihydropyridine calcium channel blocker or a thiazide diuretic) is
recommended when blood pressure remains above goal (130/80 mmHg in high-risk diabetic
patients).
,5. A 28-year-old female presents to the clinic with painful, swollen joints in both hands,
particularly the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints,
lasting for over 2 hours every morning. She also notes generalized fatigue and low-grade
fever. Laboratory tests reveal a positive rheumatoid factor (RF) and elevated anti-cyclic
citrullinated peptide (anti-CCP) antibodies. Which medication class is considered first-line
disease-modifying therapy for this condition?
A. Nonsteroidal anti-inflammatory drugs (NSAIDs) as monotherapy
B. Disease-modifying antirheumatic drugs (DMARDs), specifically methotrexate
C. Systemic high-dose long-term oral corticosteroids
D. Colchicine daily
Answer: B
Rheumatoid arthritis is characterized by symmetric inflammatory polyarthritis; early
introduction of conventional synthetic DMARDs, primarily methotrexate, is essential to
prevent joint destruction and deformity.
6. A 50-year-old male presents for an evaluation of recurrent, excruciatingly painful
attacks involving the first metatarsophalangeal joint of his right foot. The joint is
erythematous, warm, and exquisitely tender to light touch. Arthrocentesis of the joint fluid
reveals needle-shaped, negatively birefringent crystals under polarized light microscopy.
Which of the following is the most effective initial intervention for an acute attack?
A. Allopurinol 300 mg orally daily
B. Colchicine, NSAIDs, or oral corticosteroids
C. High-dose oral probenecid
D. Immediate surgical debridement of the joint capsule
Answer: B
Acute gouty arthritis flares are managed with anti-inflammatory agents such as colchicine,
NSAIDs, or corticosteroids; urate-lowering therapy like allopurinol should not be initiated
during an acute attack as it can exacerbate or prolong the flare.
7. A 62-year-old male with a history of chronic heart failure presents with worsening
dyspnea on exertion, paroxysmal nocturnal dyspnea, and bilateral lower extremity pitting
edema up to the knees. His current medications include furosemide, lisinopril, and
metoprolol succinate. On physical exam, he has jugular venous distention and an S3 gallop.
, Which diagnostic test is the gold standard for evaluating his current ventricular ejection
fraction and wall motion abnormalities?
A. 12-lead electrocardiogram
B. Transthoracic echocardiogram (TTE)
C. Serum N-terminal pro-B-type natriuretic peptide (NT-proBNP)
D. Right heart catheterization
Answer: B
Transthoracic echocardiography is the primary non-invasive imaging modality used to assess
left ventricular ejection fraction, chamber dimensions, and valvular or wall motion
abnormalities in heart failure.
8. A 19-year-old college student is brought to the university health center with a 1-day
history of high fever, severe headache, photophobia, and a non-blanching petechial rash on
her trunk and lower extremities. She has a positive Kernig and Brudzinski sign. What is
the most critical immediate clinical action?
A. Schedule an outpatient magnetic resonance imaging (MRI) scan for the following week
B. Immediately administer empiric intravenous broad-spectrum antibiotics and dexamethasone
before performing diagnostic lumbar puncture if delayed
C. Administer oral antipyretics and observe in the waiting room for 2 hours
D. Obtain a throat swab for viral culture and discharge with rest instructions
Answer: B
Suspected bacterial meningitis, particularly when accompanied by purpuric or petechial
rashes suggestive of meningococcemia, constitutes a medical emergency requiring immediate
parenteral antimicrobial therapy and adjunctive steroids.
9. A 45-year-old female presents with recurrent episodes of heartburn, acid regurgitation,
and a chronic dry cough, particularly when lying flat at night. Lifestyle modifications and
over-the-counter antacids have provided no relief. Which of the following is the most
appropriate initial pharmacotherapy?
A. Proton pump inhibitor (PPI) such as omeprazole 20 mg daily for 8 weeks
B. Sucralfate 1 gram orally four times daily
