DRUGS AFFECTING GI MOTILITY CH 58 NUR187 EXAM
QUESTIONS AND ANSWERS WITH COMPLETE VERIFIED
SOLUTIONS
(?): drug that blocks the stimulation of the gastrointestinal (GI) tract, leading to
decreased activity and increased time for absorption of needed nutrients and
water
antidiarrheal
(?): agent that increases in bulk, frequently by osmotic pull of fluid into the feces;
the increased bulk stretches the GI wall, causing stimulation and increased GI
movement
bulk-forming laxatives
(?): agent that stimulates the normal GI reflexes by chemically irritating the lining
of the GI wall, leading to increased activity in the GI tract
chemical stimulant:
Ducosate is what drug class? What does it do?
lubricant: agent that increases the viscosity of the feces, making it difficult to absorb
water from the bolus and easing movement of the bolus through the intestines
What class is loperamide? What does it do?
antidiarrheal: drug that blocks the stimulation of the gastrointestinal (GI) tract, leading to
decreased activity and increased time for absorption of needed nutrients and water
, Drugs are used to affect the motor activity or motility of the gastrointestinal (GI)
tract can do so in several different ways. How can they treat constipation? How
do the treat diarrhea?
They can be used to speed up or improve the movement of intestinal contents along the
GI tract when movement becomes too slow or sluggish to allow for proper excretion of
wastes, as in constipation.
Drugs are also used to increase the tone of the GI tract and to stimulate motility
throughout the system.
They can also be used to decrease movement along the GI tract when rapid movement
decreases the time for the absorption of nutrients, leading to a loss of water and
nutrients and the discomfort of diarrhea
(?) or cathartic, drugs are for the short-term relief of constipation, to prevent
straining when it is clinically undesirable (such as after surgery, myocardial
infarction [MI], or obstetrical delivery) to evacuate the bowel for diagnostic
procedures, to remove ingested poisons from the lower GI tract, and as an
adjunct in anthelmintic therapy when it is desirable to flush helminths from the GI
tract
Laxatives
Most (?) are available in over-the-counter (OTC) preparations, and they have the
potential for overuse so that people become dependent on them for stimulation of
GI movement. Such people may develop chronic intestinal disorders as a result.
Measures such as instituting proper diet and exercise, adequate fluid intake, and
