Which term refers to a condition in which there is an abnormally low number of platelets, increasing bleeding risk?

• A. Remission
• B. Thrombocytopenia
• C. Osteoporosis
• D. Counterfeit medication

Answer: (B)

A low platelet count, known as thrombocytopenia, is the condition being tested. Platelets are essential for clotting, helping to seal vessels after injury. When their numbers drop, the body's ability to form clots diminishes, so bleeding risk rises. This can show up as easy bruising, tiny red or purple spots on the skin (petechiae), gum or nosebleeds, and longer bleeding after cuts. Normal platelet counts are typically around 150,000 to 450,000 per microliter; thrombocytopenia is diagnosed when counts fall below the lower end of that range. Causes vary, including bone marrow problems, certain medicines, autoimmune issues, or infections, and severe decreases can lead to spontaneous bleeding.

Remission describes a reduction or disappearance of disease symptoms, osteoporosis is a loss of bone density, and counterfeit medication refers to fake drugs—none of these describe an abnormally low platelets situation.
