Answer to Question 1

ANS: C
The machine should be set so that a breath can be initiated with minimal patient effort.

Answer to Question 2

ANS: C
A sensitivity or trigger level of 1 to 2 cm H2O is adequate for most patients. Initially, system pressure is set to between 10 and 15 cm H2O.

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.
