PART I: NUTRITION ASSESSMENT

1. Pepsinogen is converted to pepsin when it comes in contact with
a. enterokinase.
b. trypsinogen.
c. hydrochloric acid.
d. peptidases.
ANS: c
Pepsinogen is secreted in the stomach and converted to its active form
by the acid environment of the stomach. Enterokinase is secreted by the
brush border of the small intestine in response to the presence of chyme.
Trypsinogen is secreted by the pancreas and activated by enterokinase.
Various peptidases are secreted by the either brush border or the
pancreas.
PTS: 1
2. Which of the following is formed by bacterial synthesis in the colon?
a. Vitamin K
b. Vitamin D
c. Vitamin B6
d. Niacin
ANS: a
Colonic bacteria produce vitamin K, vitamin B12, thiamin, and riboflavin.
Vitamin D may be metabolized by exposure of precursor vitamin D in
the skin to ultraviolet light. The human body can synthesize niacin from
the amino acid tryptophan. Vitamin B6 must be obtained from dietary
sources such as meats, whole grains, vegetables, and nuts.
PTS: 1
3.After surgical removal of a large portion of the small intestine, what
functional complication is most likely to develop?
, a. Changes in dietary habits
b. Impaired digestion
c. Loss of absorptive tissue
d. Elimination of dietary residue
ANS: c
The small intestine is the primary site of nutrient absorption because of
its large absorption surface area. Secretions from the liver, gallbladder,
and pancreas can still contribute to digestion of intestinal contents.
However, decreased absorption of nutrients and food components may
result in more intestinal remains and residue. A patient may change
dietary habits as a result of gastrointestinal discomfort experienced after
intestinal resection, but this is not a functional complication.
PTS: 1
4.The sight or smell of food produces vagal stimulation of the parietal
cells of the gastric mucosa, resulting in the increased production of
what?
a. Motilin
b. Gastrin
c. Cholecystokinin
d. Secretin
ANS: b
Parasympathetic innervation that causes secretion of gastrin and release
of hydrochloric acid helps prepare the stomach for the potential of
receiving food. After food chyme is passed into the small intestine from
the stomach, secretin and cholecystokinin are secreted to stimulate
pancreatic secretion of water and bicarbonate. They also signal
gallbladder contractions and colonic motility, all resulting in reductions
in stomach emptying and duodenal motility. Motilin is secreted from the
duodenal mucosa during fasting to stimulate gastric emptying and
intestinal motility.
PTS: 1
5. If a patient experiences malabsorption of fat resulting from an
