Answer to Question 1

C
Feedback:
The GI system is the only system that is open to the external environment. The definition of a system is multiple organs working together to perform a function or functions. Many systems are lined with epithelial tissue. The GI tract is not sterile and does contain bacteria.

Answer to Question 2

D
Feedback:
Acute salicylate toxicity may occur at doses of 20 to 25 g in adults or 4 g in children. Options A, B, and C would not be high enough to indicate salicylate toxicity.
