Welcome to your 6. 🩸 Venous Thromboembolism: Deep Vein Thrombosis & Pulmonary Embolism Arena — 40 Integrated MCQs
1.
A 45-year-old woman has unilateral calf pain and swelling. Compression ultrasonography demonstrates normal compressibility of the examined deep vein, but the overall clinical suspicion remains important. What is the best interpretation?
2.
A patient has unilateral leg swelling together with sudden dyspnea and pleuritic chest discomfort. What is the most appropriate clinical interpretation?
3.
Which clinical feature in a patient with suspected pulmonary embolism most strongly suggests severe hemodynamic compromise?
4.
A 60-year-old man with suspected PE has tachycardia and hypoxemia. Echocardiography shows right ventricular strain. What is the most appropriate interpretation of this finding?
5.
A 71-year-old hospitalized patient with reduced mobility develops calf swelling and later sudden dyspnea with pleuritic chest pain. Which sequence best explains the progression?
6.
A patient presents with sudden dyspnea, tachycardia and pleuritic chest pain. Chest radiography shows no major abnormality. Pulmonary embolism remains clinically likely. What is the most appropriate interpretation of the chest radiograph?
7.
A patient with confirmed DVT has no major contraindication to treatment. What is the principal therapeutic approach?
8.
A patient with acute DVT has a major contraindication to anticoagulation. Which intervention may be considered in selected patients to reduce further embolization?
9.
A postoperative patient develops confirmed DVT and is started on anticoagulation. Which complication should be specifically monitored as a consequence of treatment?
10.
A patient with malignancy and recent hospitalization presents with unilateral leg swelling. D-dimer is elevated. Why should the clinician avoid diagnosing DVT from this result alone?
11.
A patient with confirmed pulmonary embolism is tachycardic but normotensive and has no evidence of circulatory collapse. Which management principle is most appropriate?
12.
A 67-year-old man has been confined to bed for several days after major surgery. He develops unilateral calf swelling and discomfort. Which mechanism most directly increases his risk of venous thrombosis?
13.
A patient with suspected lower-limb DVT undergoes compression ultrasonography. Which finding most strongly supports the diagnosis?
14.
A hemodynamically stable patient has symptoms strongly suggestive of pulmonary embolism and sufficient clinical probability to require definitive imaging. Which test best demonstrates the suspected vascular lesion?
15.
A patient treated for DVT returns with new sudden dyspnea and syncope. Blood pressure is low. Which interpretation best integrates the new presentation?
16.
Which investigation is most useful for identifying the likely venous source of embolism in a patient with suspected pulmonary embolism and unilateral leg swelling?
17.
What is the main therapeutic effect of anticoagulation in acute venous thromboembolism?
18.
A thrombus from a deep vein in the lower limb becomes detached. Which complication is most directly related to its migration through the venous circulation?
19.
A 45-year-old woman with recent surgery suddenly develops breathlessness and pleuritic chest pain. Which diagnosis is most important to consider?
20.
A patient with confirmed proximal DVT has active major bleeding that prevents safe anticoagulation. Which intervention may be considered to reduce the risk of embolization?
21.
What is the most useful role of D-dimer testing in a patient with a low clinical probability of venous thromboembolism?
22.
A patient with pulmonary embolism remains hypotensive despite initial supportive measures. Which change in management is most appropriate compared with a stable patient?
23.
A patient with confirmed DVT asks why the medical team is interested in whether the event followed surgery or occurred without an obvious trigger. Why is this distinction clinically relevant?
24.
Which combination best represents Virchow's triad in venous thromboembolism?
25.
A hemodynamically stable patient has a high clinical suspicion of pulmonary embolism. Which investigation is most commonly used to confirm the diagnosis?
26.
A patient has an elevated D-dimer level during evaluation for suspected DVT. Which statement best describes this result?
27.
A patient with acute pulmonary embolism becomes hypoxemic despite adequate ventilation of parts of the lung. Which disturbance best explains this finding?
28.
A 64-year-old woman develops painful swelling of one leg 5 days after abdominal surgery. The limb is edematous and warmer than the opposite side. She has no chest symptoms. Which next step best follows the diagnostic approach taught for suspected DVT?
29.
A medical team is caring for a hospitalized patient at high risk of venous thromboembolism but without current DVT or PE. Which strategy best reflects the prevention principles taught in the learning material?
30.
CT pulmonary angiography in a breathless postoperative patient demonstrates an intraluminal filling defect in a pulmonary arterial branch. What does this finding represent?
31.
Pulmonary embolism can cause hypoxemia primarily because obstruction of pulmonary blood flow produces which physiological disturbance?
32.
A patient with pulmonary embolism develops a large obstruction of the pulmonary arterial circulation. Which cardiac effect is most likely?
33.
Which finding on CT pulmonary angiography most strongly supports pulmonary embolism?
34.
A 62-year-old man with pulmonary embolism develops hypotension and distended neck veins. Which physiological change most directly links the embolus to his circulatory deterioration?
35.
A patient receiving treatment for acute venous thromboembolism asks why anticoagulation is needed if it does not immediately dissolve the existing clot. Which explanation is most accurate?
36.
A 52-year-old woman presents with sudden swelling and pain of the left leg after prolonged immobility. Which diagnosis should be considered first?
37.
A patient with confirmed pulmonary embolism develops shock and persistent hemodynamic instability. Which additional treatment principle should be considered urgently?
38.
A 58-year-old man with unilateral calf swelling has a low clinical probability of DVT. His D-dimer is negative. Which interpretation is most appropriate?
39.
A woman presents with painful unilateral leg swelling. The limb is erythematous, and examination reveals an obvious skin infection with no major VTE risk context. Which diagnostic principle is most important?
40.
Which patient has the strongest recognized risk context for developing venous thromboembolism?
