, Which of the following types of diarrhea would most likely occur with a bacterial GI
infection?
a. Osmotic
b. Secretory
c. Hypotonic
d. Motility - ANSWERS--ANS: B
Bacterial infections lead to secretory diarrhea. A nonabsorbable substance in the
intestine leads to osmotic diarrhea. Hypotonic diarrhea is not a form of diarrhea.
Food is not mixed properly, digestion and absorption are impaired, and motility is
increased, leading to motility diarrhea.

A 20-year-old recently diagnosed with lactose intolerance eats an ice cream cone
and develops diarrhea. This diarrhea can be classified as _____ diarrhea.
a. osmotic
b. secretory
c. hypotonic
d. motility - ANSWERS--ANS: A
A nonabsorbable substance in the intestine leads to osmotic diarrhea. Infections lead
to secretory diarrhea. Hypotonic diarrhea is not a form of diarrhea. Food is not mixed
properly, digestion and absorption are impaired, and motility is increased leading to
motility diarrhea.

Assuming that midline epigastric pain is caused by a stimulus acting on an
abdominal organ, the pain felt is classified as:
a. visceral.
b. somatic.
c. parietal.
d. referred. - ANSWERS--ANS: A
Visceral pain arises from a stimulus (distention, inflammation, and ischemia) acting
on an abdominal organ. Somatic is a form of parietal pain. Parietal pain, from the
parietal peritoneum, is more localized and intense than visceral pain, which arises
from the organs themselves. Referred pain is visceral pain felt at some distance from
a diseased or affected organ.
REF: p. 909
The most common disorder associated with upper GI bleeding is:
a. diverticulosis.
b. hemorrhoids.
c. esophageal varices.
d. cancer - ANSWERS--ANS: C
Esophageal varices is the most common disorder associated with upper GI bleeding.
Diverticulosis could lead to bleeding, but it would be lower GI rather than upper.
Hemorrhoids can lead to bleeding, but they would be lower GI. Cancer could lead to
upper GI bleeding, but peptic ulcers and varices are identified as more common.
