The home care nurse is providing teaching to the family of a patient with multiple myeloma. Which nursing diagnosis should guide the nurse for this teaching?

A. Vascular occlusion is not a common complication in multiple myeloma; the focus is usually on bone and renal issues. B. Multiple myeloma causes bone destruction and weakness, increasing the risk for fractures and injury. Teaching should emphasize safety measures to protect bones at home. C. Airway clearance is not typically compromised in multiple myeloma unless there is a rare mediastinal mass. D. Fluid volume deficit related to bleeding is not a primary concern in multiple myeloma; anemia and bone lesions are more significant issues.
