Venous stasis, endothelial injury, hypercoagulability
Venous stasis, hypertension, hypercoagulability
Endothelial injury, stroke, hypertension
Hypercoagulability, myocardial infarction, stroke
What can cause endothelial injury, increasing the risk of pulmonary embolism?

Hypertension
What is the effect of increased pressure in the small circulatory system?
Decrease in pulmonary artery pressure
Increase in pulmonary artery pressure and right ventricular afterload
Decrease in pulmonary vascular resistance
Increase in oxygenation levels
What happens to pulmonary artery pressure during pulmonary embolism when more than 50% of the pulmonary artery tract is occluded?
Pulmonary artery pressure decreases due to vasodilation.
Pulmonary artery pressure remains unchanged.
Pulmonary artery pressure increases due to pulmonary vasoconstriction.
Pulmonary artery pressure increases due to reduced blood flow.
Which part of the heart is highly sensitive to pressure (PAP; afterload) but not very sensitive to volume (preload)?
Left atrium
Right ventricle
Left ventricle
Right atrium
What is the result of increased right ventricular afterload on the heart's function?
Increased right ventricular ejection
Reduced right ventricular ejection leading to acute right heart failure
Increased systemic blood pressure
Improved coronary perfusion pressure
What is the Bernheim effect in the context of increased pressure in the right ventricle?
The right ventricle shifts to the left side, improving left ventricular function.
The right ventricle shifts to the left side, causing severe diastolic dysfunction of the left ventricle.
The left ventricle shifts to the right side, reducing systemic blood pressure.
The left ventricle shifts to the right side, increasing cardiac output.
What happens to coronary perfusion pressure due to increased pressure in the right atrium?
Coronary perfusion pressure increases, improving heart function.
Coronary perfusion pressure decreases, aggravating right heart failure.
Coronary perfusion pressure remains unchanged.
Coronary perfusion pressure decreases, improving systemic blood pressure.
Which of the following is NOT a risk factor for thromboembolism?
Heart failure
Obesity
Nephrotic syndrome
Regular exercise
What is the main risk factor for thromboembolism in women of childbearing age?
Obesity
Oral contraception ("pill")
Nicotine abuse
Increased blood viscosity
At what percentage of pulmonary arterial vasculature occlusion does pulmonary arterial (PA) pressure start to increase?
10-20%
20-30%
30-50%
50-70%
What systolic blood pressure level is considered a sign of hemodynamic instability in patients with pulmonary embolism (PE)?
Less than 120 mmHg
Less than 100 mmHg
Less than 90 mmHg
Less than 80 mmHg
What is the recommended range of isotonic crystalloid volume to administer cautiously in hypotensive patients with suspected PE?
100-200 ml
200-300 ml

400-500 ml
What is the target mean arterial pressure (MAP) to maintain in patients with suspected PE?
MAP ≥ 55 mmHg
MAP ≥ 60 mmHg
MAP ≥ 65 mmHg
MAP ≥ 70 mmHg
What is the Bernheim effect?
A condition where the left ventricle enlarges due to increased blood flow.
A phenomenon where right ventricular pressure rises, causing the interventricular septum to bow toward the left ventricle.
A decrease in pulmonary arterial pressure due to reduced cardiac output.
A condition where the right ventricle fails to pump blood effectively.
Which of the following is a parenteral anticoagulant used for the initial treatment of acute pulmonary embolism (PE)?
Rivaroxaban
Enoxaparin
Apixaban
Warfarin
What is the preferred agent for the initial treatment of most hemodynamically stable PE patients?
Unfractionated Heparin (UFH)
LMWH and Fondaparinux
Oral Factor Xa Inhibitors
Warfarin
Why is Unfractionated Heparin (UFH) preferred in high-risk or unstable clinical situations?
It has a long half-life.
It requires minimal monitoring.
It has a rapid onset and short half-life, allowing for quick reversal.
It is cleared primarily by the kidneys.
Which anticoagulant is safer for patients with severe renal failure?
LMWH
Fondaparinux
Unfractionated Heparin (UFH)
Rivaroxaban
What is the rationale for using UFH in critically ill patients in the ICU?
It is cleared by the kidneys.
It allows for minute-to-minute dose adjustments.
It has a long half-life.
It is preferred for stable PE patients.
Which oral anticoagulants are used in stable patients for the initial treatment of acute PE?
Enoxaparin and Dalteparin
Fondaparinux and UFH
Rivaroxaban and Apixaban
Warfarin and Heparin
What is the primary reason LMWH and Fondaparinux are harder to reverse compared to UFH?
They have a longer half-life.
They are cleared by the liver.
They require intensive monitoring.
They are used only in unstable patients.
