The nursing instructor is talking with her clinical group about the hypothalamic–pituitary axis (HPA) and what happens when a need arises to interact with the total system. The instructor explains that this can create what?
A) A negative feedback system
B) Homeostasis
C) Complications
D) Maximum efficiency
C
Feedback:
This system (i.e., the HPA) also can create complications, especially when a need exists to override or interact with the total system, as is the case with replacement therapy or treatment of endocrine disorders. Interactions with the total system cannot create a negative feedback system, homeostasis, or maximum efficiency. The other options are incorrect.
