Answer to Question 1

B
When an increased PaCO2 is accompanied by acidemia (decreased pH), acute ventilatory failure, or respiratory acidosis, is said to exist. Clinically, this is a medical emergency that may require mechanical ventilation.

Answer to Question 2

B
Plasmapheresis can shorten a severe case of Guillain-Barr by removing the antibodies that attack the peripheral nerves.
