EXAM QUESTIONS AND CORRECT ANSWERS
TOP GRADE SCORE GUARANTEE, GRADED A+
encopresis - ANSWER>>a disorder characterized by repeated stool evacuation in
inappropriate places in children over the age of four
primary: children who never reached continence
secondary: children who reached continence for at least a year and are now
relapsed
sympathetic nervous system role - ANSWER>>*involuntary*
When the rectum is empty, the SNS inhibits the contraction of the rectal wall,
and contracts the internal anal sphincter (IAS) to prevent leakage
parasympathetic nervous system role - ANSWER>>when the rectum is filled post
mass transit, it stretches and the PNS sends information to the CNS to
coordinate bowel elimination. The rectum then contracts in conjunction with
the ENS and the IAS relaxes. Feces then moves down the anal canal to the
external anal sphincter (EAS)
enteric nervous system - ANSWER>>The intrinsic nervous system within the
bowel wall. This system responds to a variety of stimuli and generates
peristalsis
rectoanal inhibitory reflex - ANSWER>>the involuntary relaxation of the IAS
when the rectum is stretched that allows feces to move down anal canal
sampling reflex - ANSWER>>when rectal contents contact Anoderm (receptors
at distal anal canal) for differentiation
,allows squamous epithelium below the Denate Line with sensory receptors that
differentiate between solid, liquid, gaseous rectal contents
anal wink - ANSWER>>with cotton swab, swipe at 5 and 7 o'clock on the
buttocks with the patient in the modified lithotomy position
a focused physical exam that assesses prostate and pelvic muscle control and
verifies function of pudendal nerve
bulbocavernosus reflex - ANSWER>>in modified lithotomy position, squeeze
penis glans to verify external anal sphincter wink or flick the clitoris in females
a focused physical exam that assesses prostate and pelvic muscle control and
verifies function of pudendal nerve
5 factors that promote continence - ANSWER>>1: colonic transit, stool volume,
and consistency
2: sensory awareness
3: sphincter competence
4: rectal compliance and capacity
5: extrinsic factors
secretory diarrhea - ANSWER>>The absorptive capacity of the bowel is
overwhelmed by the volume of water and electrolytes that are secreted into it
osmotic (absorptive) diarrhea - ANSWER>>inadequate or reduced absorption of
the bowel
functional (motility) diarrhea - ANSWER>>Increased motility results in
decreased contact time of the stool with the lumen and intestinal mucosa
, external anal sphincter - ANSWER>>composed of smooth muscle that maintains
sphincter tone (contraction) and striated muscle that permits voluntary
control/contractility
parasympathetic nervous system - ANSWER>>part of the autonomic nervous
system that acts to promote colonic peristalsis and motility activity
sympathetic nervous system - ANSWER>>part of the autonomic nervous system
that acts to reduce intestinal motility and secretions
soluble fiber - ANSWER>>foods that contain soluble fiber have the ability to
absorb and retain water
*use to help resolve diarrhea
insoluble fiber - ANSWER>>foods that contain insoluble fiber add bulk to the
stool and do not absorb water
*use to help resolve constipation
irritable bowel syndrome - ANSWER>>cause is unknown but thought to be
multifactorial including: multifactorial: visceral hypersensitivity, enhanced GI
permeability known as "leaky gut", altered composition of the GI microbiota,
low-grade inflammation, altered immune response, autonomic nervous system
dysfunction, altered bile acid metabolism, and psychological distress
IBS s/s - ANSWER>>Abdominal pain, bloating and distention, feelings of
incomplete emptying, changes in stool frequency and consistency, pain relieved
by defecation, Abdominal pain associated with eating and intraluminal
stimulation such as gas, constipation and/or diarrhea
obstructed defecation syndrome - ANSWER>>disorders that are characterized
by the inability to eliminate normally, even when the stool is an ideal
