1. A 45-year-old male presents to the primary care clinic complaining of a sudden, severe headache
described as "the worst headache of my life" accompanied by acute neck stiffness and
photophobia. What is the most critical initial diagnostic action?
A. Prescribe oral sumatriptan and schedule an outpatient neurology follow-up in one week
B. Order an emergent non-contrast head CT followed by a lumbar puncture if imaging is
negative
C. Perform a physical exam focusing solely on cranial nerves and provide reassurance
D. Initiate a 5-day course of high-dose oral corticosteroids for suspected tension headache
CORRECT ANSWER : B
Rationale: A sudden, severe "thunderclap" headache is a red-flag symptom indicative of a
subarachnoid hemorrhage or other intracranial vascular emergency. An emergent non-contrast
head CT is the gold standard initial imaging modality, and a lumbar puncture is required if the
CT is negative but clinical suspicion remains high.
,2. A 68-year-old female with a history of hypertension and type 2 diabetes mellitus presents with
progressive dyspnea on exertion, orthopnea, and bilateral lower extremity pitting edema. An
echocardiogram reveals an ejection fraction of 35%. Which pharmacological class serves as a
foundational cornerstone of therapy to reduce mortality and morbidity in this condition?
A. Non-dihydropyridine calcium channel blockers
B. Angiotensin-Converting Enzyme (ACE) Inhibitors or Angiotensin Receptor-Neprilysin
Inhibitors (ARNIs)
C. Short-acting beta-2 adrenergic agonists
D. First-generation antihistamines
CORRECT ANSWER : B
Rationale: ACE inhibitors or ARNIs (such as sacubitril/valsartan) block detrimental
neurohormonal activation of the renin-angiotensin-aldosterone system, significantly reducing
mortality, hospitalizations, and ventricular remodeling in heart failure with reduced ejection
fraction.
3. A nurse practitioner is evaluating a 55-year-old male for chronic stable angina. He has a
documented severe true allergy to aspirin. Which alternative antiplatelet agent is recommended
for secondary prevention of cardiovascular events?
A. Low-dose ibuprofen taken twice daily
B. Clopidogrel 75 mg PO daily
C. Warfarin titrated to a target INR of 2.0 to 3.0
D. High-dose acetaminophen daily
CORRECT ANSWER : B
Rationale: For patients with established cardiovascular disease who cannot take aspirin due to
hypersensitivity or severe allergy, clopidogrel is the recommended P2Y12 inhibitor monotherapy
alternative for secondary prevention.
4. A 24-year-old female presents with acute onset dyspnea, dry cough, and wheezing that
consistently worsen during physical exercise and exposure to cold air. Spirometry reveals a post-
bronchodilator improvement in FEV1 of 15%. What is the primary pathophysiology underlying
this condition?
A. Permanent destruction of alveolar walls and loss of elastic recoil
, B. Chronic airway inflammation, hyperresponsiveness, and reversible airflow obstruction
C. Fixed fibrotic narrowing of the terminal bronchioles
D. Accumulation of purulent secretions in large central airways
CORRECT ANSWER : B
Rationale: Asthma is characterized by chronic airway inflammation, bronchial
hyperresponsiveness, and episodic bronchoconstriction that is characteristically reversible with
bronchodilator therapy, distinguishing it from fixed obstructive disorders like COPD.
5. A 70-year-old male presents for an annual wellness exam. He has a 30 pack-year smoking
history and quit smoking 5 years ago. According to current U.S. Preventive Services Task Force
(USPSTF) guidelines, what is the appropriate lung cancer screening recommendation for this
patient?
A. No screening is necessary since he successfully quit smoking over 4 years ago
B. Annual screening with low-dose computed tomography (LDCT)
C. Biennial chest radiography (X-ray) starting at age 75
D. Sputum cytology testing every six months
CORRECT ANSWER : B
Rationale: USPSTF guidelines recommend annual lung cancer screening with LDCT in adults
aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit
within the past 15 years.
6. A 50-year-old female presents with fatigue, cold intolerance, weight gain, and constipation.
Laboratory evaluation reveals a significantly elevated TSH and a low free T4 level. Which
medication regimen is indicated?
A. Methimazole daily with monitoring of white blood cell counts
B. Levothyroxine initiated at a low dose and titrated based on TSH levels every 6 to 8
weeks
C. Propylthiouracil divided twice daily
D. Liothyronine monotherapy at high loading doses
CORRECT ANSWER : B
, Rationale: Primary hypothyroidism is treated with synthetic levothyroxine replacement. Therapy
is initiated conservatively and adjusted incrementally every 6 to 8 weeks according to serum
TSH levels until a euthyroid state is achieved.
7. A 32-year-old female presents with palpitations, heat intolerance, fine tremors, and unexplained
weight loss. Laboratory results show suppressed TSH and elevated free T4 and T3 levels. Which
diagnostic test is most appropriate to differentiate Graves' disease from subacute thyroiditis?
A. Complete blood count with differential
B. Radioactive iodine uptake (RAIU) scan
C. Magnetic resonance imaging of the brain
D. Fasting blood glucose and HbA1c
CORRECT ANSWER : B
Rationale: A radioactive iodine uptake and scan helps determine the etiology of thyrotoxicosis;
Graves' disease demonstrates diffuse increased uptake, whereas subacute thyroiditis shows near-
absent uptake due to leakage of stored hormone.
8. A 60-year-old male with type 2 diabetes mellitus and hypertension is found to have a persistent
microalbuminuria on random spot urine testing. Which drug class should be prioritized in his
management plan to provide renal protection?
A. Thiazide diuretics
B. ACE inhibitors or Angiotensin Receptor Blockers (ARBs)
C. Loop diuretics
D. Dihydropyridine calcium channel blockers
CORRECT ANSWER : B
Rationale: ACE inhibitors or ARBs reduce intraglomerular pressure by preferentially dilating
the efferent arteriole, which slows the progression of diabetic nephropathy and reduces urinary
albumin excretion.
9. A 28-year-old pregnant patient at 28 weeks gestation is diagnosed with gestational diabetes
mellitus managed initially with diet and exercise. After two weeks, blood glucose logs
consistently exceed target ranges. Which pharmacological agent is considered the preferred first-
line medical therapy in pregnancy?
A. Glyburide
