Which statement below is incorrect about a deep vein thrombosis (DVT)?
Veins that are most susceptible to a deep vein thrombosis are the peroneal, posterior tibial, popliteal and superficial femoral
DVTS tend to mostly occur in the lower extremities but can occur in the upper extremities too
A DVT is a type of venous thromboembolism (VTE), which is a blood clot that starts in the vein
A deep vein thrombosis in the lower extremity has a low probability of becoming a pulmonary embolism
The Correct Answer is D
A. Veins that are most susceptible to a deep vein thrombosis are the peroneal, posterior tibial, popliteal and superficial femoral: This statement is correct. These veins are indeed among the most common sites for the development of DVT.
B. DVTs tend to mostly occur in the lower extremities but can occur in the upper extremities too: This statement is also correct. While DVTs primarily occur in the lower extremities, they can occur in the upper extremities as well, particularly in individuals with risk factors such as central venous catheters or certain medical conditions.
C. A DVT is a type of venous thromboembolism (VTE), which is a blood clot that starts in the vein: This statement is correct. DVTs are indeed classified as venous thromboembolism, which refers to blood clots that form in the venous system.
D. A deep vein thrombosis in the lower extremity has a low probability of becoming a pulmonary embolism: This statement is incorrect. A deep vein thrombosis in the lower extremity has a significant risk of becoming a pulmonary embolism if a thrombus dislodges and travels to the pulmonary circulation. It is essential to monitor and treat DVTs to reduce the risk of complications like pulmonary embolism.

Correct Answer is B
Explanation
A. Septal: Septal cardiomyopathy typically refers to abnormalities in the interventricular septum and does not specifically address the rigidity and noncompliance of the myocardium that affects diastolic filling.
B. Restrictive: Restrictive cardiomyopathy is characterized by a rigid and noncompliant myocardium that impedes ventricular filling during diastole. This results in elevated pressures in the ventricles and may lead to heart failure symptoms due to poor filling capacity.
C. Infiltrative: Infiltrative cardiomyopathy involves the deposition of abnormal substances (such as amyloid or sarcoid) within the myocardial tissue, which can lead to stiffness. While this may contribute to restrictive physiology, "restrictive" is the more precise term for the condition described.
D. Hypertrophic: Hypertrophic cardiomyopathy is characterized by an abnormal thickening of the heart muscle, particularly the left ventricle. While this condition can affect diastolic filling, it is primarily due to muscle hypertrophy rather than rigidity and noncompliance of the myocardium.
Correct Answer is A
Explanation
A. Controlling the blood pressure: Controlling blood pressure is crucial for reducing the risk of developing coronary artery disease (CAD). Even with a normal lipid panel, hypertension can significantly contribute to cardiovascular risk, and managing blood pressure helps protect against the development of CAD.
B. Moderate alcohol use: While moderate alcohol consumption may have some potential benefits for heart health, it is not a primary risk factor reduction strategy. The focus should be on more impactful lifestyle changes, particularly for individuals with normal lipid levels.
C. Eating a low-fat diet: Although a balanced diet is important for overall health, a low-fat diet specifically is not necessary for everyone, especially those with normal lipid levels. The emphasis should be on a heart-healthy diet that includes healthy fats, such as those from fish, nuts, and olive oil, rather than simply reducing fat intake.
D. Avoiding air pollution: Avoiding air pollution can have health benefits, but it is not a primary strategy for individuals seeking to reduce the risk of CAD. Addressing more direct risk factors, such as blood pressure management, is more critical in this context.
