Venous Thromboembolism - The Quiz About Blood Clots In Viens
Venous thromboembolism (VTE), a term referring to blood clots in the veins, is an underdiagnosed and serious, yet preventable medical condition that can cause disability and death. This is a quiz on general knowledge of risks, treatment and preventative measure of Venous Thromboembolism
- 1.
VTE is term for what type of condition/s?
- A.
Pulmonary Hypertension and Post Thrombotic Syndrome
- B.
Ventricular Tachycardia
- C.
Deep Vein Thrombosis and Pulmonary Embolism
- D.
Vancomycin Resistant Enterococcus
Correct Answer
C. Deep Vein Thrombosis and Pulmonary EmbolismExplanation
VTE stands for Venous Thromboembolism, which is a term used to describe the condition of having both Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE). DVT refers to the formation of blood clots in the deep veins, usually in the legs, while PE occurs when one of these clots breaks loose and travels to the lungs. Therefore, the correct answer is Deep Vein Thrombosis and Pulmonary Embolism.Rate this question:

- 2.
How does a thrombus or clot develop?
- A.
From Alterations to blood flow which cause venous stasis
- B.
Injury to the vascular endothelium
- C.
Alterations to the constitution of blood which causes hypercoagulability
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
A thrombus or clot can develop through a combination of factors. Alterations to blood flow, such as venous stasis, can slow down the movement of blood, increasing the chances of clot formation. Injury to the vascular endothelium can also trigger the clotting process, as it exposes the underlying tissue and activates clotting factors. Additionally, alterations to the constitution of blood, such as hypercoagulability, can make the blood more prone to clotting. Therefore, all of the mentioned factors can contribute to the development of a thrombus or clot.Rate this question:

From which vein is a DVT considered to be proximal? (Please choose the most correct answer)
- A.
Posterior Tibial Vein
- B.
Deep Femoral Vein
- C.
External Iliac Vein
- D.
Popliteal Vein
- E.
Great Saphenous Vein
Correct Answer
D. Popliteal VeinExplanation
A deep vein thrombosis (DVT) is considered to be proximal when it occurs in the larger veins closer to the center of the body. The popliteal vein is located behind the knee and is considered a proximal vein. This means that if a DVT is found in the popliteal vein, it is considered to be a more serious condition compared to a DVT in a more distal vein. The other veins listed in the options are either more distal or not considered to be proximal veins.Rate this question:

Which of the following is of the greatest VTE risk to an individual? (please choose the most correct answer)
- A.
Immobility
- B.
History of VTE
- C.
Dehydration
- D.
Long Haul Flight
- E.
Oral Contraception (The Pill)
Correct Answer
B. History of VTEExplanation
A history of VTE (venous thromboembolism) is the greatest VTE risk to an individual. VTE refers to the formation of blood clots in veins, which can lead to serious complications such as deep vein thrombosis (DVT) or pulmonary embolism (PE). Having a previous history of VTE increases the likelihood of developing another episode in the future. This is because certain factors that contribute to VTE, such as genetic predisposition or underlying medical conditions, may still be present. Therefore, individuals with a history of VTE should take extra precautions and follow appropriate medical advice to minimize their risk.Rate this question:

Which of the following reduces the risk of developing a VTE? (please tick more than one box)
- A.
Anticoagulant medications
- B.
Calf massage
- C.
Mobilising
- D.
Mechanical Compression with graduated compression stockings &/or intermittent pneumatic compression
- E.
Deep breathing exercises
Correct Answer(s)
A. Anticoagulant medications
C. Mobilising
D. Mechanical Compression with graduated compression stockings &/or intermittent pneumatic compressionExplanation
Anticoagulant medications, mobilizing, and mechanical compression with graduated compression stockings and/or intermittent pneumatic compression can all reduce the risk of developing a VTE. Anticoagulant medications help to prevent blood clot formation, mobilizing helps to improve blood flow and prevent stagnant blood, and mechanical compression with stockings and/or intermittent pneumatic compression helps to prevent blood pooling and promote circulation. Deep breathing exercises and calf massage may have some benefits but are not as effective in reducing the risk of developing a VTE as the other options mentioned.Rate this question:

Which patients should recieve extended VTE prophylaxis of up to 35 days?
- A.
Total hip artroplasty
- B.
Fractured Neck of Femur
- C.
Ischaemic stroke
- D.
Major Surgery Age> 60yrs
- E.
Major curative cancer surgery
Correct Answer(s)
A. Total hip artroplasty
B. Fractured Neck of Femur
E. Major curative cancer surgeryExplanation
Patients who undergo total hip arthroplasty, have a fractured neck of femur, or undergo major curative cancer surgery should receive extended VTE prophylaxis of up to 35 days. This is because these procedures are associated with a higher risk of developing venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE). Extended prophylaxis helps to prevent the formation of blood clots and reduce the risk of VTE complications in these high-risk patients. Ischaemic stroke and major surgery in patients aged over 60 years are not specifically mentioned as indications for extended VTE prophylaxis in this question.Rate this question:

Which of the following is a contraindication to mechanical prophylaxis? (please choose the most correct answer)
- A.
Varicose veins
- B.
Superficial thrombo-phelbitis
- C.
Severe peripheral arterial disease
- D.
Obesity
- E.
Previous history of VTE
Correct Answer
C. Severe peripHeral arterial diseaseExplanation
Severe peripheral arterial disease is a contraindication to mechanical prophylaxis because it can impair blood flow to the extremities. Mechanical prophylaxis, such as compression stockings or intermittent pneumatic compression devices, work by enhancing blood circulation and preventing blood clots. However, in severe peripheral arterial disease, there is already compromised blood flow, and the use of mechanical prophylaxis may further restrict blood flow, potentially causing harm to the patient. Therefore, it is not recommended in this condition.Rate this question:

What is the appropriate dose of prophylactic Enoxaparin for a medical patient?
- A.
5000u BD
- B.
60mg OD
- C.
1mg/Kg BD
- D.
40mg OD
- E.
20mg OD
Correct Answer
D. 40mg ODExplanation
The appropriate dose of prophylactic Enoxaparin for a medical patient is 40mg OD. This means that the patient should take 40mg of Enoxaparin once daily. Enoxaparin is a blood thinner used to prevent blood clots in patients who are at risk, such as medical patients. The dosage of 40mg OD is a standard prophylactic dose for these patients to reduce the risk of blood clots.Rate this question:

LWhen a patient has a confirmed acute DVT what should they wear on their legs?
- A.
Anti-thrombotic stockings
- B.
Intermittent pneumatic compression device
- C.
Nothing
- D.
Class 2 graduated compression stockings
Correct Answer
D. Class 2 graduated compression stockingsExplanation
Patients with a confirmed acute DVT should wear Class 2 graduated compression stockings on their legs. These stockings help to improve blood flow and prevent blood clots from forming or worsening. The compression provided by these stockings helps to reduce swelling and discomfort, and promotes healing and recovery. Anti-thrombotic stockings and intermittent pneumatic compression devices are also used for preventing blood clots, but in the case of a confirmed acute DVT, Class 2 graduated compression stockings are the appropriate choice. Wearing nothing on the legs would not provide any benefits in terms of preventing complications associated with DVT.Rate this question:

What are the signs & symptoms of DVT? (Please tick more than one box)
- A.
Pain
- B.
Swelling
- C.
Redness
- D.
Bruising
- E.
Heat
Correct Answer(s)
A. Pain
B. Swelling
C. Redness
E. HeatExplanation
The signs and symptoms of deep vein thrombosis (DVT) include pain, swelling, redness, and heat. Pain is commonly experienced, usually in the affected leg. Swelling occurs due to the blood clot blocking proper blood flow. Redness and heat are also present as a result of inflammation in the affected area. Bruising, however, is not typically associated with DVT and is not listed as a symptom.Rate this question:
