Answer to Question 1

ANS: A
The alarm stage, the initial reaction, is manifested by arousal of the body's defenses that prepare the body to fight or flee from threat. This stage involves the secretion of hormones and cate-cholamines to support physiologic/metabolic activity and boosts the immune system to thwart infection. The stage of resistance/adaptation is the second step as the body attempts to sustain the challenge. Exhaustion marks the breakdown of compensatory mechanisms, when the response can no longer be sustained.

Answer to Question 2

ANS: A, C
The patient is experiencing type II hypersensitivity when experiencing anemia and lymphopenia. Seizures, facial rash, and photosensitivity are not associated with type II hypersensitivity reac-tions.
