1. A 65-year-old male with a 40-pack-year smoking history presents with
hemoptysis, weight loss, and persistent cough. Chest X-ray reveals a 4 cm mass in
the right upper lobe with cavitation. Biopsy confirms malignant cells. Which
paraneoplastic syndrome is most commonly associated with this type of lung
cancer?
A. Cushing's syndrome
B. Hypercalcemia (squamous cell carcinoma)
C. SIADH (small cell carcinoma)
D. Eaton-Lambert syndrome
Rationale: Squamous cell carcinoma is the most common type of lung cancer associated
with hypercalcemia due to ectopic production of parathyroid hormone-related protein
(PTHrP). Small cell carcinoma is more commonly associated with SIADH, and both small
cell and squamous cell can cause other paraneoplastic syndromes .
2. A patient with chronic hypertension presents with progressive shortness of
breath and peripheral edema. Echocardiogram reveals concentric left ventricular
hypertrophy with normal chamber size. What is the most likely cellular adaptation
occurring in this patient's myocardium?
A. Eccentric hypertrophy
,B. Concentric hypertrophy
C. Physiologic hyperplasia
D. Metaplasia
Rationale: Concentric hypertrophy occurs in response to pressure overload (e.g.,
hypertension) where the ventricular wall thickens without chamber enlargement. Eccentric
hypertrophy, characterized by chamber dilation with wall thinning, occurs in volume
overload states .
3. A 45-year-old female with a history of systemic lupus erythematosus (SLE)
presents with acute confusion, hypertension, and oliguria. Urinalysis reveals
hematuria, proteinuria, and cellular casts. Which type of hypersensitivity reaction
is primarily responsible for lupus nephritis?
A. Type I hypersensitivity
B. Type II hypersensitivity
C. Type III hypersensitivity
D. Type IV hypersensitivity
Rationale: Type III hypersensitivity reactions are mediated by immune complex deposition.
In lupus nephritis, circulating immune complexes (antibody-antigen complexes) deposit in
the renal glomeruli, activating complement and causing inflammation. Type II is antibody-
mediated (e.g., myasthenia gravis). Type IV is T-cell mediated (e.g., contact dermatitis) .
4. A newborn infant presents with respiratory distress, cyanosis, and grunting
respirations within the first hour of life. Chest X-ray shows diffuse ground-glass
opacities and air bronchograms. Which of the following risk factors is most
strongly associated with this condition?
A. Maternal hypertension
B. Post-term delivery
C. Prematurity and maternal diabetes
D. Prolonged rupture of membranes
Rationale: Respiratory distress syndrome (RDS) of the newborn is caused by surfactant
deficiency, most commonly in premature infants. Maternal diabetes increases the risk by
delaying surfactant production .
,5. A 68-year-old male with a history of coronary artery disease presents with
progressive dyspnea, orthopnea, and paroxysmal nocturnal dyspnea. Physical
examination reveals S3 gallop, crackles in the lung bases, and jugular venous
distention. Which hemodynamic parameter is most elevated in this condition?
A. Systemic vascular resistance
B. Pulmonary capillary wedge pressure (PCWP)
C. Central venous pressure
D. Right ventricular systolic pressure
Rationale: Left-sided heart failure results in elevated left ventricular end-diastolic pressure,
which is reflected in increased pulmonary capillary wedge pressure (PCWP). This leads to
pulmonary congestion, dyspnea, and orthopnea. S3 gallop is a classic finding in heart
failure .
6. A patient with chronic hepatitis B develops cirrhosis. Laboratory studies reveal
elevated serum ammonia, prolonged prothrombin time, and decreased albumin.
Which hepatic function is most directly reflected by the prolonged prothrombin
time?
A. Bile production
B. Ammonia metabolism
C. Synthesis of clotting factors
D. Bilirubin conjugation
Rationale: The liver synthesizes all clotting factors except factor VIII. Prolonged
prothrombin time in cirrhosis reflects decreased synthesis of vitamin K-dependent clotting
factors (II, VII, IX, X). This indicates significant hepatic synthetic dysfunction .
7. A 32-year-old female presents with progressive proximal muscle weakness,
difficulty swallowing, and diplopia that worsens with repeated activity. Which
autoimmune antibody is most specific for this condition?
A. Anti-dsDNA
B. Rheumatoid factor
, C. Anti-acetylcholine receptor (AChR) antibody
D. Anti-Jo-1 antibody
Rationale: Myasthenia gravis is characterized by antibodies directed against the
acetylcholine receptor at the neuromuscular junction. The weakness worsens with
repetitive activity (fatigability) and improves with rest. Anti-AChR antibodies are present in
85-90% of patients .
8. A 55-year-old male with a 30-year history of type 2 diabetes presents with
progressive peripheral neuropathy, retinopathy, and microalbuminuria. Which
pathological process is most responsible for these complications?
A. Autoimmune destruction of beta cells
B. Non-enzymatic glycation and oxidative stress
C. Insulin resistance in peripheral tissues
D. Decreased glucose uptake
Rationale: Chronic hyperglycemia causes complications through multiple mechanisms
including non-enzymatic glycation of proteins (advanced glycation end-products),
oxidative stress, and activation of the polyol pathway. These processes damage small
blood vessels (microvascular complications) causing nephropathy, retinopathy, and
neuropathy .
9. A 70-year-old female with hypertension and hyperlipidemia presents with
sudden onset of severe headache, nausea, and photophobia. CT head reveals
subarachnoid hemorrhage. What is the most common cause of this type of
hemorrhage?
A. Hypertension
B. Arteriovenous malformation
C. Ruptured saccular aneurysm
D. Trauma
Rationale: Subarachnoid hemorrhage is most commonly caused by rupture of a saccular
(berry) aneurysm in the circle of Willis. Risk factors include hypertension, smoking, and
family history. Hypertension is the most common cause of intraparenchymal hemorrhage
(hypertensive hemorrhage) .
