      Hemolysis

    • B.

      Hematoma

    • C.

      Homestasis

    • D.

      Hemoconcenstration

    Correct Answer
    A. Hemolysis
    Explanation
    Hemolysis refers to the destruction of red blood cells. This can occur due to various factors such as infections, autoimmune disorders, or certain medications. When red blood cells are destroyed, they release their contents, including hemoglobin, into the surrounding fluid. This can lead to the release of free hemoglobin into the bloodstream, causing various symptoms such as anemia, jaundice, and organ damage. Hemolysis can be diagnosed through blood tests that measure the levels of free hemoglobin and other markers. Treatment depends on the underlying cause and may involve addressing the underlying condition, providing supportive care, or in severe cases, blood transfusions.
