Thrombocytopenia predisposes to which complication?

Thrombocytopenia predisposes to which complication?

• A. Infection
• B. Bleeding
• C. Seizures
• D. Edema

Answer: (B)

Low platelet count reduces the body's ability to form a proper platelet plug after vessel injury, so hemostasis is impaired. Platelets are essential for the initial hemostatic response: they adhere to the damaged endothelium, aggregate to form a plug, and release substances that help stabilize the clot. When platelets are scarce, even minor injuries can lead to bleeding, and spontaneous mucosal bleeding can occur. That’s why thrombocytopenia most directly predisposes to bleeding. Infections relate to white blood cells, seizures aren’t a direct consequence of low platelets, and edema comes from fluid balance issues rather than a bleeding risk.
