Question

What is a condition that causes a decrease in platelet count?

A) Disseminated intravascular coagulation (DIC)
B) Vitamin K deficiency
C) Autoimmune thrombocytopenia purpura (ATP)
D) Heparin-induced thrombocytopenia (HIT)

Answer 1

Thrombocytopenia is a condition characterized by a decrease in platelet count. Conditions such as DIC, ATP, and HIT can cause a decrease in platelet count, leading to problems with blood clotting and an increased risk of excessive bleeding.

Step-by-step explanation:

Thrombocytopenia is a condition characterized by a decrease in platelet count. There are several conditions that can cause thrombocytopenia, including:

1. Disseminated intravascular coagulation (DIC): A disorder that leads to excessive blood clotting and subsequent depletion of platelets.
2. Autoimmune thrombocytopenia purpura (ATP): An autoimmune disorder in which the body's immune system mistakenly attacks and destroys platelets.
3. Heparin-induced thrombocytopenia (HIT): A condition in which the use of heparin, a blood thinner, triggers an immune response that leads to decreased platelet count.

These conditions can result in a decreased platelet count, leading to problems with blood clotting and an increased risk of excessive bleeding.
