Correct Answer
B. It's the Superior of two venae cavae

Explanation
The Superior venae cavae refers to one of the two major veins that carry deoxygenated blood from the body back to the heart. It is located in the upper part of the body and is responsible for returning blood from the head, neck, upper limbs, and upper chest to the right atrium of the heart. The other major vein is called the Inferior vena cava, which carries blood from the lower part of the body.

What is CVA?
- A.
  
  Central Venae access
- B.
  
  Control venous access
- C.
  
  Central Venous Access
- D.
  
  None of the above
Correct Answer
C. Central Venous Access

Explanation
CVA stands for Central Venous Access. This refers to a procedure in which a catheter is inserted into a large vein, usually in the neck, chest, or groin, to allow for the administration of medication, fluids, or blood products directly into the bloodstream. It is commonly used in critically ill patients who require frequent or long-term intravenous access.

How many diameter is the Superior Vena Cava?
- A.
  
  12mm
- B.
  
  24mm
- C.
  
  28mm
- D.
  
  32mm
Correct Answer
B. 24mm

Explanation
The correct answer is 24mm. The Superior Vena Cava is a large vein that carries deoxygenated blood from the upper body back to the heart. It has a diameter of 24mm, which allows for efficient blood flow and transport. A larger diameter would result in slower blood flow, while a smaller diameter would impede blood flow. Therefore, a diameter of 24mm is optimal for the function of the Superior Vena Cava.

  All of the above
Correct Answer
B. Two BrachiocepHalic veins

Explanation
The Superior Cava is formed by two Brachiocephalic veins. These veins are responsible for draining blood from the upper body, including the head, neck, and upper limbs, and then merging together to form the Superior Cava. This major vein then carries the deoxygenated blood from the upper body to the right atrium of the heart.

No valve divides the Vena Cava.
- A.
  
  True
- B.
  
  False
- C.
  
  Sometimes
- D.
  
  I don't know
Correct Answer
A. True

Explanation
The statement "No valve divides the Vena Cava" is true. The Vena Cava is a large vein that carries deoxygenated blood from the body back to the heart. Unlike other veins in the body, the Vena Cava does not have valves. Valves are present in veins to prevent the backflow of blood and ensure that it flows in one direction. However, in the case of the Vena Cava, it does not require valves as the blood flow is facilitated by the pumping action of the heart.

- B.
  
  The obstruction of the Cava
- C.

- D.
  
  None of the above
Correct Answer
B. The obstruction of the Cava

Explanation
Superior Vena Cava obstruction refers to the blockage or obstruction of the superior vena cava, which is a large vein that carries deoxygenated blood from the upper body back to the heart. This obstruction can be caused by various factors such as tumors, blood clots, or inflammation. It can lead to symptoms like swelling of the face, neck, and arms, difficulty breathing, and coughing. Therefore, the correct answer is "The obstruction of the Cava".

Correct Answer
B. Cancer

Explanation
Cancer is also known as the obstruction of the Vena Cava. This is because cancerous tumors can grow and block the Vena Cava, which is a large vein that carries deoxygenated blood from the lower body back to the heart. When the Vena Cava is obstructed, it can lead to serious complications such as swelling, pain, and blood clot formation. Therefore, cancer is the correct answer in this case.

  Surgery

  Pills
- D.
  
  Vaccine
Correct Answer
A. Chemotherapy

Explanation
Chemotherapy is a treatment option for Superior Vena Cava (SVC) obstruction. SVC obstruction occurs when the superior vena cava, a large vein that carries deoxygenated blood from the upper body to the heart, becomes blocked. Chemotherapy involves the use of drugs to kill or slow down the growth of cancer cells, which can be a cause of SVC obstruction. By targeting and reducing the size of the cancerous tumor causing the obstruction, chemotherapy can help alleviate the symptoms and restore proper blood flow through the superior vena cava.
