Answer to Question 1

The X marks the area of the eye where glaucoma causes fluid to accumulate. Acute an-gle-closure and open-angle glaucoma are caused when the balance between intraocular fluid production and drainage is disrupted, resulting in increased intraocular pressure.

Answer to Question 2

B

Feedback
A Incorrect. Use of sitagliptin (Januvia), a dipeptidyl-peptidase-4 inhibitor, is in-dicated for type 2 diabetes mellitus and acts by improving glucose-dependent insulin synthesis, lowering glucagon secretion, and slowing gastric emptying.
B Correct. Meglitinides such as nateglinide (Starlix) act by helping the pancreas to release insulin.
C Incorrect. Metformin (Glucophage) acts by decreasing the release of glucose from the liver.
D Incorrect. Thiazolidinediones such as rosiglitazone (Avandia) act by enhancing insulin sensitivity with hepatic glucose metabolism and by enhancing insulin receptor kinase activity and phosphorylation.
