Answer to Question 1

ANS: D
Autoimmune disorders are failures of the tolerance to self. B and T cells produce autoantibodies that can cause pathophysiologic tissue damage. Autoimmune disorders may be described as an immune attack on the self and result from the failure to distinguish self protein from foreign protein.

Answer to Question 2

ANS: B
Provision of oxygen is the initial primary intervention. Anaphylaxis may advance very rapidly and the patient may have to be intubated. Covering the patient with a warm blanket is not wrong, but not an initial intervention.
