Bone marrow suppression can lead to which of the following blood abnormalities?

• A. Hyperkalemia
• B. Anemia, thrombocytopenia, and leukopenia
• C. Thrombosis
• D. Hyperglycemia

Answer: (B)

Bone marrow suppression reduces the production of all blood cell lines, so red cells, white cells, and platelets all decline. This leads to anemia (low red blood cells), leukopenia (low white blood cells), and thrombocytopenia (low platelets). With anemia you may feel fatigue and shortness of breath; leukopenia increases infection risk; thrombocytopenia raises the chance of easy bruising and abnormal bleeding. The other options don’t fit because hyperkalemia isn’t a direct consequence of suppressed marrow, thrombosis isn’t typically caused by low blood cell production (it’s more associated with clotting disorders or endothelial injury), and hyperglycemia isn’t linked to bone marrow function.
