1. A 55-year-old male with a history of hypertension presents with sudden onset of
severe chest pain that radiates to his back. His blood pressure is 160/90 mmHg in
the right arm and 110/70 mmHg in the left arm. Which of the following is the most
likely diagnosis?
A. Myocardial infarction
B. Pulmonary embolism
C. Aortic dissection
D. Aortic dissection
Correct Answer: D. Aortic dissection.
Rationale: The classic presentation of aortic dissection includes sudden, severe
chest or back pain and a discrepancy in blood pressure between the arms. This
occurs due to a tear in the aortic intima, allowing blood to enter the media and
create a false lumen. Myocardial infarction typically presents with crushing chest
pain and ECG changes. Pulmonary embolism presents with pleuritic chest pain,
dyspnea, and tachycardia. Pericarditis presents with sharp chest pain that is worse
with inspiration and lying flat.
2. A 68-year-old female with a history of heart failure is prescribed furosemide.
Which of the following electrolyte imbalances is most commonly associated with
this medication?
A. Hyperkalemia
B. Hypokalemia
,C. Hypokalemia
D. Hypernatremia
Correct Answer: C. Hypokalemia.
Rationale: Furosemide is a loop diuretic that acts on the ascending limb of the loop
of Henle to inhibit sodium-potassium-chloride cotransport. This leads to increased
excretion of sodium, chloride, and potassium, commonly causing hypokalemia. It
can also cause hyponatremia, hypomagnesemia, and hypocalcemia.
3. In a patient with chronic obstructive pulmonary disease (COPD), which of the
following laboratory findings is most indicative of chronic hypoxemia?
A. Decreased hematocrit
B. Increased hemoglobin
C. Increased hemoglobin
D. Decreased white blood cell count
Correct Answer: C. Increased hemoglobin.
Rationale: Chronic hypoxemia stimulates the kidneys to produce erythropoietin,
which in turn stimulates the bone marrow to increase red blood cell production.
This results in secondary polycythemia, characterized by an increased hemoglobin
and hematocrit. The elevated hemoglobin is a compensatory mechanism to
increase the oxygen-carrying capacity of the blood.
4. A patient is diagnosed with left-sided heart failure. Which of the following
findings is most characteristic of this condition?
A. Jugular venous distention
B. Peripheral edema
C. Pulmonary congestion
D. Pulmonary congestion
Correct Answer: D. Pulmonary congestion.
,Rationale: Left-sided heart failure results in the inability of the left ventricle to
effectively pump blood forward, causing blood to back up into the left atrium and
pulmonary veins. This leads to increased pulmonary capillary hydrostatic pressure,
resulting in pulmonary congestion and edema. Jugular venous distention and
peripheral edema are hallmarks of right-sided heart failure.
5. Which of the following is the primary pathophysiological mechanism
responsible for the development of atherosclerosis?
A. Vasospasm of coronary arteries
B. Endothelial injury and inflammation
C. Endothelial injury and inflammation
D. Decreased platelet aggregation
Correct Answer: C. Endothelial injury and inflammation.
Rationale: Atherosclerosis begins with endothelial injury, which can be caused by
risk factors such as hypertension, hyperlipidemia, smoking, and diabetes. This
injury triggers an inflammatory response, leading to the recruitment of monocytes
and the formation of fatty streaks. Over time, this progresses to fibrous plaques that
can occlude vessels. Vasospasm is characteristic of Prinzmetal's angina, not the
primary mechanism of atherosclerosis.
6. A 72-year-old male with a history of chronic atrial fibrillation is admitted with a
sudden onset of severe, sharp chest pain and hemoptysis. He is tachycardic and
tachypneic. A D-dimer is elevated. What is the most likely diagnosis?
A. Myocardial infarction
B. Pulmonary embolism
C. Pneumothorax
D. Pericarditis
Correct Answer: B. Pulmonary embolism.
Rationale: Atrial fibrillation is a significant risk factor for the formation of thrombi
in the left atrium. If a thrombus embolizes to the pulmonary circulation, it can
, cause a pulmonary embolism. The classic presentation includes sudden-onset
pleuritic chest pain, dyspnea, tachypnea, tachycardia, and hemoptysis. An elevated
D-dimer is a sensitive but non-specific test for thromboembolism.
7. A patient has a blood pressure of 150/95 mmHg. Which of the following
accurately describes this condition?
A. Isolated systolic hypertension
B. Prehypertension
C. Stage 1 hypertension
D. Stage 2 hypertension
Correct Answer: C. Stage 1 hypertension.
Rationale: According to the ACC/AHA guidelines, Stage 1 hypertension is defined
as a systolic blood pressure between 130-139 mmHg or a diastolic blood pressure
between 80-89 mmHg. Stage 2 hypertension is defined as a systolic pressure ≥140
mmHg or a diastolic pressure ≥90 mmHg. Isolated systolic hypertension is
characterized by a systolic pressure ≥130 mmHg with a diastolic pressure <80
mmHg.
8. In aortic stenosis, which of the following compensatory mechanisms initially
helps to maintain cardiac output?
A. Increased peripheral vascular resistance
B. Left ventricular hypertrophy
C. Decreased heart rate
D. Dilation of the aorta
Correct Answer: B. Left ventricular hypertrophy.
Rationale: Aortic stenosis increases the afterload on the left ventricle because the
left ventricle must generate higher pressure to overcome the stenotic valve and
eject blood. This chronic pressure overload leads to concentric left ventricular
hypertrophy (LVH). LVH initially helps to maintain cardiac output by increasing
