1. A patient presents with severe, crushing chest pain that radiates to the jaw and left ar
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
m. An ECG reveals ST-segment elevation in leads V1-
hg hg hg hg hg hg hg hg
V4. Which of the following is the most likely diagnosis?
hg hg hg hg hg hg hg hg hg
A. Unstable Angina
hg hg
B. Non-ST Elevation Myocardial Infarction (NSTEMI)
hg hg hg hg hg
C. ST-Elevation Myocardial Infarction (STEMI) - Anteroseptal
hg hg hg hg hg hg
D. ST-Elevation Myocardial Infarction (STEMI) - Inferior
hg hg hg hg hg hg
Correct Answer: C hg hg
Rationale: ST-segment elevation in the precordial leads V1-
hg hg hg hg hg hg hg
V4 indicates an anteroseptal wall MI, typically caused by occlusion of the left anterior descendi
hg hg hg hg hg hg hg hg hg hg hg hg hg hg
ng (LAD) coronary artery. Pain radiating to the jaw and left arm is classic for cardiac ischemia.
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
Unstable angina (A) and NSTEMI (B) do not present with ST-
hg hg hg hg hg hg hg hg hg hg
elevation. Inferior STEMI (D) would show changes in leads II, III, and aVF.
hg hg hg hg hg hg hg hg hg hg hg hg
2. A 65-year-
hg hg
old patient with a history of heart failure is prescribed furosemide. Which of the followi
hg hg hg hg hg hg hg hg hg hg hg hg hg hg
ng electrolyte imbalances is a primary concern with this medication?
hg hg hg hg hg hg hg hg hg
A. Hyperkalemia
hg
B. Hypernatremia
hg
C. Hypokalemia
hg
D. Hypercalcemia
hg
Correct Answer: C hg hg
Rationale: Furosemide is a loop diuretic that inhibits the Na-K-
hg hg hg hg hg hg hg hg hg
2Cl cotransporter in the thick ascending limb of the loop of Henle. This leads to increased excr
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
etion of sodium, chloride, and potassium, often resulting in hypokalemia. Hyperkalemia (A) is a
hg hg hg hg hg hg hg hg hg hg hg hg hg hg
concern with potassium-sparing diuretics. Hypernatremia (B) is not a typical side effect.
hg hg hg hg hg hg hg hg hg hg hg
,3. A patient with chronic obstructive pulmonary disease (COPD) has chronic hypoxemia.
hg hg hg hg hg hg hg hg hg hg hg hg
This leads to which of the following long-term compensatory mechanisms?
hg hg hg hg hg hg hg hg hg
A. Decreased erythropoietin production
hg hg hg
B. Decreased red blood cell mass
hg hg hg hg hg
C. Increased erythropoietin production and secondary polycythemia
hg hg hg hg hg hg
D. Increased oxygen saturation of hemoglobin
hg hg hg hg hg
Correct Answer: C hg hg
Rationale: Chronic hypoxemia stimulates the kidneys to produce more erythropoietin, which in
hg hg hg hg hg hg hg hg hg hg hg h
turn stimulates the bone marrow to increase red blood cell production (secondary polycythemi
g hg hg hg hg hg hg hg hg hg hg hg hg
a). This is a compensatory attempt to increase the oxygen-carrying capacity of the blood.
hg hg hg hg hg hg hg hg hg hg hg hg hg
4. A patient is diagnosed with type 1 diabetes mellitus. The underlying pathophysiology
hg hg hg hg hg hg hg hg hg hg hg hg hg
involves:
A. Insulin resistance at the cellular level
hg hg hg hg hg hg
B. Autoimmune destruction of pancreatic beta cells
hg hg hg hg hg hg
C. Impaired glucose uptake in skeletal muscle
hg hg hg hg hg hg
D. Deficiency of glucagon
hg hg hg
Correct Answer: B hg hg
Rationale: Type 1 diabetes is an autoimmune disease where the body's immune system attack
hg hg hg hg hg hg hg hg hg hg hg hg hg
s and destroys the insulin-
hg hg hg hg
producing beta cells in the pancreas. Insulin resistance (A and C) is the hallmark of type 2 diab
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
etes. A deficiency of glucagon (D) is not the cause.
hg hg hg hg hg hg hg hg hg
5. Which of the following best describes the pathophysiology of septic shock?
hg hg hg hg hg hg hg hg hg hg hg
A. Massive vasoconstriction leading to hypertension
hg hg hg hg hg
B. Decreased cardiac output due to pump failure
hg hg hg hg hg hg hg
C. Systemic vasodilation, increased capillary permeability, and maldistribution of blood flow
hg hg hg hg hg hg hg hg hg hg
D. Obstruction of blood flow in the pulmonary vasculature
hg hg hg hg hg hg hg hg
Correct Answer: C hg hg
Rationale: Septic shock is characterized by a massive systemic inflammatory response to infecti
hg hg hg hg hg hg hg hg hg hg hg hg
on. This causes widespread vasodilation (decreased systemic vascular resistance), increased capi
hg hg hg hg hg hg hg hg hg hg
llary permeability (leading to third-
hg hg hg hg
spacing of fluid), and maldistribution of blood flow, resulting in tissue hypoperfusion and hypot
hg hg hg hg hg hg hg hg hg hg hg hg hg
ension.
,6. In liver failure, why does hyperammonemia occur?
hg hg hg hg hg hg hg
A. Increased breakdown of proteins by the liver
hg hg hg hg hg hg hg
B. Failure of the liver to convert ammonia to urea
hg hg hg hg hg hg hg hg hg
C. Decreased renal excretion of ammonia
hg hg hg hg hg
D. Increased absorption of ammonia from the GI tract
hg hg hg hg hg hg hg hg
Correct Answer: B hg hg
Rationale: The liver's primary role in ammonia metabolism is to convert it into urea via the ure
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
a cycle, which is then excreted by the kidneys. In liver failure, this detoxification process is impa
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
ired, leading to a buildup of ammonia in the blood (hyperammonemia), which can cross the bl
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
ood-brain barrier and cause hepatic encephalopathy.
hg hg hg hg hg
7. A patient with a history of peptic ulcer disease develops a sudden onset of severe, sha
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
rp abdominal pain. On exam, the abdomen is rigid and board-
hg hg hg hg hg hg hg hg hg hg
like. Which complication is most likely?
hg hg hg hg hg
A. Gastric outlet obstruction
hg hg hg
B. Upper GI bleeding
hg hg hg
C. Perforation
hg
D. Penetration into the pancreas
hg hg hg hg
Correct Answer: C hg hg
Rationale: A sudden onset of severe, sharp pain with a rigid, board-
hg hg hg hg hg hg hg hg hg hg hg
like abdomen is the classic presentation of a perforated peptic ulcer. This allows gastrointestina
hg hg hg hg hg hg hg hg hg hg hg hg hg
l contents, including air and acid, to enter the peritoneal cavity, causing a chemical peritonitis t
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
hat leads to guarding and rigidity.
hg hg hg hg hg
8. The pathophysiological mechanism responsible for the development of atherosclerosis
hg hg hg hg hg hg hg hg hg h
begins with:
g hg
A. Plaque rupture and thrombus formation
hg hg hg hg hg
B. Smooth muscle cell proliferation in the tunica media
hg hg hg hg hg hg hg hg
C. Endothelial injury and dysfunction
hg hg hg hg
D. Deposition of calcium in the arterial wall
hg hg hg hg hg hg hg
Correct Answer: C hg hg
Rationale: The initiation of atherosclerosis is widely accepted to be endothelial injury or dysfun
hg hg hg hg hg hg hg hg hg hg hg hg hg
ction caused by factors like hypertension, hyperlipidemia, smoking, and diabetes. This injury inc
hg hg hg hg hg hg hg hg hg hg hg hg
reases vascular permeability, allowing LDL cholesterol to enter the intima, where it becomes oxi
hg hg hg hg hg hg hg hg hg hg hg hg hg
dized and triggers an inflammatory response.
hg hg hg hg hg
, 9. A patient has a cerebrovascular accident (CVA) affecting the left hemisphere. Which of
hg hg hg hg hg hg hg hg hg hg hg hg hg
the following deficits is most characteristic?
hg hg hg hg hg hg
A. Left-sided hemiparesis and neglect
hg hg hg hg
B. Aphasia and right-sided hemiparesis
hg hg hg hg
C. Ataxia and dysmetria
hg hg hg
D. Bilateral blindness and confusion
hg hg hg hg
Correct Answer: B hg hg
Rationale: The left hemisphere is dominant for language in most individuals. A stroke in the lef
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
t middle cerebral artery territory will typically cause aphasia (difficulty with language) and right-
hg hg hg hg hg hg hg hg hg hg hg hg hg
sided motor and sensory deficits (right hemiparesis/hemiplegia) because the motor and sensor
hg hg hg hg hg hg hg hg hg hg hg
y tracts decussate at the medulla.
hg hg hg hg hg
10. Which of the following is the primary mechanism of tissue injury in ischemic stroke?
hg hg hg hg hg hg hg hg hg hg hg hg hg hg
A. Excitotoxicity due to glutamate release
hg hg hg hg hg
B. Direct physical compression of brain tissue
hg hg hg hg hg hg
C. Formation of an amyloid plaque
hg hg hg hg hg
D. Demyelination of neurons
hg hg hg
Correct Answer: A hg hg
Rationale: In ischemic stroke, the lack of oxygen and glucose leads to a failure of the Na+/K+
hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg hg
ATPase pump, causing depolarization and massive release of the excitatory neurotransmitter gl
hg hg hg hg hg hg hg hg hg hg hg
utamate. Glutamate overstimulates NMDA receptors, leading to a lethal influx of calcium into t
hg hg hg hg hg hg hg hg hg hg hg hg hg
he neuron, initiating a cascade of cell death (excitotoxicity).
hg hg hg hg hg hg hg hg
11. A patient with asthma is experiencing an acute exacerbation. Which of the following
hg hg hg hg hg hg hg hg hg hg hg hg hg hg
pathophysiological changes is most responsible for the expiratory wheezing? hg hg hg hg hg hg hg hg
A. Constriction of pulmonary arterioles
hg hg hg hg
B. Narrowing of the airways due to bronchospasm, edema, and mucus
hg hg hg hg hg hg hg hg hg hg
C. Collapse of the alveoli due to surfactant deficiency
hg hg hg hg hg hg hg hg
D. Fluid accumulation in the alveolar spaces
hg hg hg hg hg hg
Correct Answer: B hg hg
Rationale: Wheezing, particularly on expiration, is a hallmark of asthma. It is caused by turbule
hg hg hg hg hg hg hg hg hg hg hg hg hg hg
nt airflow through narrowed airways. The narrowing is due to a combination of bronchospasm,
hg hg hg hg hg hg hg hg hg hg hg hg hg hg
mucosal edema, and increased mucus production. Airway obstruction is worse during expiratio
hg hg hg hg hg hg hg hg hg hg hg
n because positive intrathoracic pressure compresses the airways further.
