Which statement about multiple myeloma is accurate?

Show Answers

There is an elevation in the IgM spike.Kidney damage results from plasma cells directly depositing in glomerular capillaries.IL-8 serves as a biomarker for bone lesions.Alkaline phosphatase levels are consistently elevated.

Explanation

Option A is correct because multiple myeloma is characterized by an increased IgM spike. The other options are incorrect: kidney damage is typically caused by light chain deposition rather than plasma cells themselves; IL-8 is not a recognized marker for bone lesions; and alkaline phosphatase does not always rise in multiple myeloma.
