A nurse is teaching a class on Alzheimer's disease to a group of nurses. One of the nurses asks how a cholinesterase inhibitor drug works in the Alzheimer's patient. The nurse's best response would be
a. "It helps the healthier nerve cells transmit impulses better."
b. "It promotes excretion of neurotoxins."
c. "It reverses central nervous system cell degeneration."
d. "It helps grow new nerve cells to replace damaged ones in the brain."
ANS: A
Cholinesterase inhibitors prevent the breakdown of acetylcholine by acetylcholinesterase. In patients with Alzheimer's disease, the result is enhanced transmission by central cholinergic neurons that have not yet been destroyed.
A cholinesterase inhibitor does not promote the excretion of neurotoxins.
A cholinesterase inhibitor does not reverse central nervous system degeneration.
A cholinesterase inhibitor does not stimulate new nerve cell growth.
