Which of the following is incorrecta)Increase in RBC count is polycyth...
Explanation:A: Increase in RBC count is polycythemia- This statement is correct because polycythemia refers to an increase in the number of red blood cells (RBCs) in the blood, which can lead to increased blood viscosity and the possibility of blood clots.B: Decrease in leucocyte count is called as leucopenia- This statement is also correct. Leucopenia refers to a decrease in the number of white blood cells (leucocytes) in the blood, which can make a person more susceptible to infections.C: Decrease in Thrombocyte count is called as Thrombocytopenia- This statement is correct as well. Thrombocytopenia refers to a decrease in the number of platelets (thrombocytes) in the blood, which can lead to issues with blood clotting and an increased risk of bleeding.D: Purpura a group of bleeding disorders is due to increase in platelet count- This statement is incorrect. Purpura is a group of bleeding disorders characterized by the appearance of purple or red spots on the skin due to bleeding underneath the skin. However, purpura is not caused by an increase in platelet count; rather, it is usually caused by a decrease in platelet count (thrombocytopenia), issues with blood clotting factors, or damage to blood vessels.
Which of the following is incorrecta)Increase in RBC count is polycyth...
Explanation:
The incorrect statement is option 'D': Purpura, a group of bleeding disorders, is due to an increase in platelet count.
Purpura:
Purpura is a condition characterized by purple or red discoloration of the skin or mucous membranes, resulting from bleeding underneath the skin. It is caused by various factors, including platelet abnormalities, vascular disorders, and coagulation disorders. However, an increase in platelet count is not the cause of purpura.
Polycythemia:
Polycythemia is a condition characterized by an increase in the number of red blood cells (RBCs) in the blood. It can be primary (polycythemia vera) or secondary to other conditions. An increase in RBC count leads to an increase in blood viscosity and can cause complications such as clot formation.
Leucopenia:
Leucopenia is a condition characterized by a decrease in the number of white blood cells (leucocytes) in the blood. It can be caused by various factors, including bone marrow disorders, viral infections, autoimmune diseases, and certain medications. Leucopenia weakens the immune system, making individuals more susceptible to infections.
Thrombocytopenia:
Thrombocytopenia is a condition characterized by a decrease in the number of platelets (thrombocytes) in the blood. It can be caused by factors such as bone marrow disorders, immune system disorders, medications, and certain infections. Thrombocytopenia can result in abnormal bleeding and easy bruising.
Conclusion:
In summary, the incorrect statement is option 'D', which states that purpura, a group of bleeding disorders, is due to an increase in platelet count. Purpura is not caused by an increase in platelet count but rather by various factors, including platelet abnormalities, vascular disorders, and coagulation disorders.
