1. A 45-year-old male presents to the primary care clinic complaining of a 3-week history of
worsening left-sided lower back pain that radiates down the posterior aspect of his left thigh and
calf to the foot. He reports numbness in the lateral aspect of his left foot. Physical examination
reveals diminished ankle jerk reflex on the left, weakness when walking on his toes, and a
positive straight leg raise test at 35 degrees. Which lumbar nerve root is most likely involved in
this patient's pathology?
A. L3 nerve root
B. L4 nerve root
C. S1 nerve root
D. L2 nerve root
CORRECT ANSWER : C
Rationale: Involvement of the S1 nerve root typically manifests as posterior leg and calf pain,
diminished or absent ankle jerk reflex, weakness in plantarflexion (walking on toes), and sensory
loss along the lateral/posterior foot. Option A involves the anterior thigh and knee reflex. Option
B affects the anterior-medial shin and knee jerk reflex. Option D involves proximal hip flexion
and anterior thigh sensation.
,2. A 32-year-old female presents with recurrent episodes of intense, throbbing unilateral headaches
accompanied by nausea, vomiting, photophobia, and phonophobia lasting approximately 18
hours each. These episodes are frequently triggered by stress and menstruation and are severely
debilitating. She has tried over-the-counter analgesics with no relief. Which of the following is
the most appropriate first-line abortive pharmacotherapy for moderate-to-severe migraine attacks
in this patient?
A. Propranolol hydrochloride daily
B. Sumatriptan succinate oral tablet at onset of headache
C. Amitriptyline nightly
D. Topiramate daily maintenance
CORRECT ANSWER : B
Rationale: Triptans, such as sumatriptan, are specific serotonin receptor agonists used as first-
line abortive therapy for moderate-to-severe acute migraines. Options A, C, and D are
prophylactic medications used to reduce attack frequency, not acute abortive agents.
3. A 68-year-old male with a history of hypertension, type 2 diabetes mellitus, and hyperlipidemia
presents for an annual wellness exam. His current blood pressure is 142/88 mmHg. His estimated
glomerular filtration rate (eGFR) is 58 mL/min/1.73m2, and urine albumin-to-creatinine ratio is
elevated at 45 mg/g. According to current ADA and JNC 8 guidelines, which pharmacological
agent should be initiated as first-line therapy to provide both blood pressure control and renal
protection?
A. A thiazide diuretic like chlorthalidone
B. An Angiotensin-Converting Enzyme (ACE) inhibitor or Angiotensin Receptor Blocker
(ARB)
C. A dihydropyridine calcium channel blocker like amlodipine
D. A beta-blocker like metoprolol tartrate
CORRECT ANSWER : B
Rationale: ACE inhibitors or ARBs are the preferred first-line agents for patients with
hypertension and chronic kidney disease or albuminuria because they reduce intraglomerular
pressure and slow the progression of renal disease. Options A and C lower blood pressure
effectively but lack the specific nephroprotective anti-proteinuric efficacy of renin-angiotensin
system blockade. Option D is not first-line for uncomplicated hypertension or primary renal
protection.
,4. A 55-year-old postmenopausal female presents with insidious onset of right knee pain that
worsens with prolonged standing and weight-bearing activities and improves with rest. She notes
mild morning stiffness lasting less than 15 minutes. Examination reveals crepitus, bony
enlargement, and reduced range of motion without significant joint effusion or erythema.
Weight-bearing radiographs show joint space narrowing and osteophytes. What is the most
appropriate initial management strategy?
A. Immediate referral for total knee arthroplasty surgery
B. A comprehensive regimen combining structured low-impact aerobic exercise, weight
management, and topical NSAIDs
C. High-dose oral systemic corticosteroid therapy
D. Intra-articular methotrexate injections
CORRECT ANSWER : B
Rationale: First-line management for osteoarthritis emphasizes non-pharmacological modalities
including physical therapy, weight reduction, and topical NSAIDs or acetaminophen. Option A is
premature until conservative options fail or functional impairment is severe. Option C and D are
indicated for inflammatory arthritides like rheumatoid arthritis, not primary osteoarthritis.
5. A 24-year-old female presents with a 4-day history of dysuria, frequent urination, and suprapubic
discomfort. She denies fever, flank pain, or vaginal discharge. Urinalysis reveals positive
leukocyte esterase, positive nitrites, and numerous white blood cells. She has no known drug
allergies and no recent antibiotic exposure. Which of the following is the most appropriate
empirical first-line antibiotic regimen?
A. Ciprofloxacin 500 mg orally twice daily for 7 days
B. Nitrofurantoin monohydrate/macrocrystals 100 mg orally twice daily for 5 days
C. Azithromycin 1 gram orally as a single dose
D. Amoxicillin-clavulanate 875 mg orally twice daily for 10 days
CORRECT ANSWER : B
Rationale: Nitrofurantoin is a recommended first-line agent for uncomplicated lower urinary
tract infections in females, given for 5 days. Option A is a fluoroquinolone, which should be
reserved for complicated UTIs or second-line use due to adverse effect profiles. Option C treats
chlamydia rather than typical uropathogens. Option D is broader spectrum than necessary for
standard uncomplicated cystitis.
, 6. A 50-year-old male presents with acute onset of severe, excruciating pain, redness, and swelling
in the first metatarsophalangeal joint of his right foot, starting overnight. He reports a recent
heavy seafood dinner and alcohol consumption. Serum uric acid is elevated. Arthrocentesis
reveals negatively birefringent needle-shaped crystals under polarized light microscopy. What is
the preferred first-line pharmacotherapy for treating this acute gout flare?
A. Allopurinol daily maintenance therapy
B. Colchicine or NSAIDs (such as indomethacin) initiated promptly
C. Probenecid daily
D. High-dose systemic loop diuretics
CORRECT ANSWER : B
Rationale: Acute gout flares are managed with anti-inflammatory agents such as NSAIDs,
colchicine, or corticosteroids to suppress acute inflammation. Option A and C are urate-
lowering therapies and should not be initiated during an acute flare as they can precipitate or
prolong the attack.
7. A 60-year-old male with a 40 pack-year smoking history presents with a 3-month history of
progressive shortness of breath, chronic cough productive of white sputum, and wheezing.
Spirometry demonstrates a post-bronchodilator FEV1/FVC ratio of 0.65 and an FEV1 of 52% of
predicted. According to GOLD guidelines, how is this patient's chronic obstructive pulmonary
disease classified?
A. GOLD 1 (Mild)
B. GOLD 2 (Moderate)
C. GOLD 3 (Severe)
D. GOLD 4 (Very Severe)
CORRECT ANSWER : B
Rationale: GOLD classification based on post-bronchodilator FEV1 defines GOLD 2
(Moderate) as an FEV1 between 50% and 79% of predicted in the presence of an FEV1/FVC
ratio below 0.70. Option A requires FEV1 $\ge$ 80%. Option C requires FEV1 between 30%
and 49%. Option D requires FEV1 < 30%.
8. A 19-year-old college student presents with a 1-week history of severe fatigue, low-grade fever,
sore throat, and posterior cervical lymphadenopathy. Physical examination reveals marked
pharyngeal erythema and tender posterior cervical nodes, along with mild splenomegaly. A
