Which response by the nurse is appropriate when caring for a patient with chronic inflammatory
demyelinating polyneuropathy (CIDP) who has been admitted to the intensive care unit whose
spouse asks why the patient is receiving high-dose IV immunoglobulin (IVIG)?
"Immunoglobulin therapy is the only way to treat CIDP."
"Patients with CIDP are unable to take oral medications, so we always use IV therapy."
"It is best to do this type of treatment first and then start corticosteroids."
"Immunotherapy is effective because they directly address the cause of the disease."
