The nurse is caring for a patient who received a bone marrow transplant 10 days ago. The nurse would monitor for which of the following clinical manifestations that could indicate a potentially life-threatening situation?

A) Mucositis
B) Confusion
C) Depression
D) Mild temperature elevation

During the first 100 days after a bone marrow transplant, patients are at high risk for life-threatening infections. The earliest sign of infection in an immunosuppressed patient can be a mild fever. Mucositis, confusion, and depression are possible clinical manifestations but are representative of less life-threatening complications.
