All are true regarding treatment of Guillain-Barre syndrome, EXCEPT: 
Select and explain. 
A. Coicosteroid are used for early recovery and to prevent complications, B. High-dose intravenous immune globulin can be initiated, C. Plasmapheresis can be indicated, D. High-dose intravenous immune globulin and plasmapheresis are equally effective
A: Coicosteroid are used for early recovery and to prevent complications
Answer: A: Coicosteroid are used for early recovery and to prevent complications 
Explanation: In the vast majority of patients with GBS, treatment should be initiated as soon after diagnosis as possible. 2 weeks after the first motor symptoms, immunotherapy is no longer effective. Either high-dose intravenous immune globulin (IVIg) or plasmapheresis can be initiated, as they are equally effective. A combination of the two therapies is not significantly better than either alone. Glucocoicoid administration does not shoen the course or prognosis of GBS.
