B) The drugs work by crossing the bloodbrain barrier and cure the disease in the brain.
C) The drugs work by increasing ACh levels in the brain and reverse the progression of the disease.
D) The drugs work by crossing the bloodbrain barrier and decreasing ACh levels in the neuromuscular junctions.

Answer to Question 1

A
Feedback:
Acetylcholinesteras e inhibitors that cross the bloodbrain barrier are used to manage Alzheimer's disease by increasing ACh levels in the brain and slowing the progression of the disease. Decreasing ACh levels in the brain does not slow the progression, reverse the progression, or cure the disease. Decreasing ACh levels at the neuromuscular junctions has no effect on Alzheimer's disease.

Answer to Question 2

B
Feedback:
Knowledge of recent travel can help the nurse to pinpoint potential exposure to helminths, parasites, or other infection exposure common in the area visited. The nurse should specifically ask about foreign travel to countries where malaria or parasitic roundworms are common. Sexual history, dietary habits, or any blood transfusions that the patient may have had before would not be adequately explored by questioning travel history.
