Answer to Question 1

C, D
Feedback:
The neuropathologic hallmarks of Alzheimer's disease are neuritic plaques and neurofibrillary tangles. Gliomas, meningiomas, and AVMs are not associated with Alzheimer's disease.

Answer to Question 2

B
Feedback:
Sitagliptin (Januvia) minimizes the rate of inactivation of the incretin hormones to increase hormone levels and prolong their activity. Sitagliptin does not block the S phase of the cell cycle. Sitagliptin is not a synthetically prepared monosodium salt. Sitagliptin does not inhibit hydrogen, potassium, and ATPase.
