Answer to Question 1

A
The cause of MS is not known, but it is attributed to an environmental factor (bacteria, virus, or chemical) combining with a genetic predisposition for the disease. Current thought also includes the hypothesis that MS is an autoimmune disease where the immune system attacks healthy cen-tral nervous system tissues.

Answer to Question 2

D
These findings are normal. The nurse should document the normal recovery assessment and con-tinue to monitor. There is no indication of chilling, hemorrhage, or respiratory distress, which respectively would require blanket application, charge nurse notification, or raising the head of the bed.
