Question

A condition in which there is severe loss of extra-cellular fluid due to hemorrhage, diarrhea, severe vomiting or sweating followed by shrinkage of blood volume, reduction of venous inflow to the heart, reduction of cardiac output and fall of blood pressure is known as:

• A. Hypovolemic shock
• B. Anaphylactic shock
• C. Septic shock
• D. Cardiogenic shock

Answer 1

The Correct Option is A

The condition described in the question refers to a severe loss of extracellular fluid due to several possible reasons like hemorrhage, diarrhea, severe vomiting, or sweating. This subsequently leads to a reduction in blood volume, decreased venous return to the heart, lowered cardiac output, and ultimately a drop in blood pressure. These symptoms collectively describe a medical condition known as Hypovolemic shock.

Let's analyze each of the options to understand why Hypovolemic shock is the correct answer:

1. Hypovolemic Shock:
   • Caused by a significant loss of blood or fluids, which leads to a decrease in blood volume.
   • This loss of volume results in insufficient blood flow to organs, causing the symptoms described such as reduced venous return, decreased cardiac output, and lowered blood pressure.
   • This condition requires immediate medical intervention to prevent organ failure.
2. Anaphylactic Shock:
   • Caused by a severe allergic reaction to a substance (such as food, insect stings, or medication).
   • Primary symptoms include difficulty in breathing, drop in blood pressure, and swelling. Although there is a drop in blood pressure, it stems from a different cause than fluid loss.
3. Septic Shock:
   • Due to severe infection leading to overwhelming immune response throughout the body.
   • Characteristics include a significant drop in blood pressure due to the dilation of blood vessels and poor organ perfusion, rather than fluid loss.
4. Cardiogenic Shock:
   • Occurs when the heart fails to pump blood efficiently, usually because of damage to the heart muscle, often due to a severe heart attack.
   • The problem here lies within the heart pumping mechanism rather than the loss of fluid volume.

In summary, Hypovolemic shock is characterized by severe fluid loss and fits the description given in the question's scenario, such as shrinkage of blood volume and reduction in cardiac output and blood pressure.
