Answer to Question 1

C
A lower than normal PaO2 of about 60 mm Hg or less will stimulate the peripheral chemoreceptors. These chemoreceptors will not be stimulated by pain or anxiety, normal PaCO2, or normal venous pH.

Answer to Question 2

D
While Guillain-Barr syndrome can be found in males and females of any age and ethnicity, individuals over 45 year of age are most frequently affected.
