Answer to Question 1

ANS: C
Parkinson's disease (PD) is characterized by an imbalance of dopamine (DA) and acetylcholine (ACh) caused by an unexplained degeneration of the dopaminergic neurons allowing the excitatory response of acetylcholine to exceed the inhibitory response of dopamine. Alzheimer's disease (AD) may result from decreased ACh, degeneration of cholinergic neurons, and neuritic plaques. Dopamine does not appear to play a role in Alzheimer's disease.

Answer to Question 2

ANS: C
Magnesium sulfate is used to control seizures during eclampsia.
