Systemic effects of diarrhea include..?
dehydration, electrolyte imbalance, & weight loss
(Disorders of the GI tractsigns and symptoms)
Which term refers to the lack of a desire to eat this nonspecific symptom is often associated with nausea, abdominal pain, diarrhea, and psychological stress?
Also, side effects of medications and disorders of other organ systems, including cancer, heart disease, and kidney disease, are often accompanied by this symptom.
Anorexia
(Disorders of the GI tract signs & symptoms) Which term refers to the forceful emptying of the stomach and intestinal contents (chyme) through the mouth? Nausea and retching (dry heaves) are distinct events that usually precede ___
Which can be due to extreme pain, stomach or duodenum distension, motion sickness, side effects of medications, the trauma of ovaries, testes, uterus, bladder or kidney
Vomiting (emesis)
(Disorders of the GI tract signs & symptoms) Which term refers to a subjective experience associated with various conditions, including abnormal pain and labyrinthine stimulation (i.e., spinning movement)? Also, hypersalivation & tachycardia are common associated symptoms
Nausea
(Disorders of the GI tract signs & symptoms) Which term refers to the muscular event of vomiting without the expulsion of vomitus?
Retching
(Disorders of the GI tract signs & symptoms) Which term refers to spontaneous vomiting not preceded by nausea or retching, caused by direct stimulation of the vomiting centre by neurological lesions (e.g., increased intracranial pressure, tumours, or aneurysms) involving the brainstem or can be a symptom of GI obstruction (pyloric stenosis)?
Projectile vomiting
(Disorders of the GI tract signs & symptoms) The metabolic consequences of vomiting & nausea are…?
- Fluid, electrolyte, and acid–base disturbances, including hyponatremia, hypokalemia, hypochloremia, & metabolic alkalosis
Which term refers to difficult or infrequent defecation, which is particularly prevalent among older adults, and usually means a decrease in the number of bowel movements per week, hard stools, and difficult evacuation?
Constipation
List the 3 categories of primary constipation
- Normal transit (functional)
- Slow transit
- Pelvic floor dysfunction or outlet dysfunction
Which term refers to a normal rate of stool passage, but there is difficulty with stool evacuation, associated with a sedentary lifestyle, low-residue diet (the habitual consumption of highly refined foods), or low fluid intake?
Normal-transit constipation
Which term refers to impaired colonic motor activity with infrequent bowel movements, straining to defecate, mild abdominal distension, and palpable stool in the sigmoid colon?
Slow-transit constipation
Which term refers to inability or difficulty expelling stool because of dysfunction of the pelvic floor muscles or anal sphincter? Examples including pelvic floor dyssynergia, rectal fissures, strictures, or hemorrhoids.
Pelvic floor dysfunction
Which term refers to constipation that can be caused by diet, medications, or neurogenic disorders (e.g., stroke, Parkinson’s disease, spinal cord lesions, multiple sclerosis, Hirschsprung’s disease) in which neural pathways or neurotransmitters are altered and colon transit time delayed?
Can also be caused by opiates, antacids, iron, that Inhibit motility, endocrine or metabolic disorders (hypothyroidism, Diabetes mellitus), diverticuli, irritable bowel syndrome, & pregnancy
Secondary constipation
Indicators of constipation include two of the following for at least 3 months:
(1-4) At least 25 % of the time
(5) fewer than __ bm per week
(1) Straining with defecation ; (2) lumpy or hard stools; (3) sensation of incomplete emptying ; (4) manual manoeuvres to facilitate stool evacuation; and (5) fewer than three bowel movements per week.
Which term refers to hard, dry stool retained in the rectum, associated with rectal bleeding, abdominal or cramping pain, nausea and vomiting, weight loss, episodes of diarrhea, hemorrhoids, itching, & anal fissures?
Fecal impaction
Which term refers to he presence of loose, watery stools?
Diarrhea
Acute diarrhea is ___
Persistent diarrhea lasts__
& chronic diarrhea lasts __
- more than 3 loose stools within 24 hours lasting less than 14 days
- between 14 to 30 days
- longer than 4 weeks
Diarrhea in which the volume of feces is increased is called__? And is generally associated caused by excessive amounts of water or secretions or both in the intestines
Diarrhea in which volume of feces is not increased, which usually results from excessive intestinal motility, is called?
- Large-volume diarrhea
- Small-volume diarrhea
The 3 major mechanisms of diarrhea are called?
Osmotic, secretory, & motile
Which term refers to excessive fluid drawn into the intestinal lumen by osmosis, caused by nonabsorbable sugars, full strength tube feeds, or dumping syndrome? (Producing large volume diarrhea)
Osmotic diarrhea
Which term refers to excessive mucosal secretion of fluid & electrolytes, which can be caused by infections or inflammatory disorders?
Secretory diarrhea
Which term refers to excessive GI motility which decreases transit time and opportunity for fluid absorption, resulting in diarrhea? Caused by resection of the small intestine (short bowel syndrome), or surgical bypass of an area of the intestine?
Motility diarrhea
Systemic effects of prolonged diarrhea include..?
Dehydration, electrolyte imbalance (hyponatremia, hypokalemia), & weight loss
Manifestations of acute bacterial or viral infection resulting in diarrhea include..?
Fever, with or without vomiting and cramping
Fever, cramping pain, and bloody stools accompany chronic diarrhea caused by..?
Inflammatory bowel disease (IBD) or dysentery
Steatorrhea (fat in the stools), bloating, and diarrhea are common signs of …?
Malabsorption syndrome
Which term refers to the presenting symptom of a number of GI diseases & can be acute or chronic?
Which can be caused by..?
Where abdominal organs are not sensitive to mechanical stimuli, such as cutting, tearing, or crushing, however, they are sensitive to..?
This pain is described as..?
- Abdominal pain
- Stretching (mechanical), inflammation, or ischemia (insufficient blood supply).
- Stretching & distension
- Sharp, dull, or colicky.
Abdominal pain can either..?
Parietal (somatic), visceral, or referred pain
(Abdominal pain) Which term refers from the parietal peritoneum, and is more localized and intense than visceral pain, which arises from the organs themselves?
Parietal pain
(Abdominal pain) Which term refers to pain arising from a stimulus (distension, inflammation, ischemia) acting on an abdominal organ, which is poorly localized, diffuse, or vague with a radiating pattern?
Visceral pain
