Q

Liver

A

Main functions

  1. Metabolize carbohydrates, protein, and fats
  2. Metabolize medications to prepare them for excretion
  3. Synthesize glucose, protein (Albumin), cholesterol, triglycerides, and clotting factors.
  4. Detoxify blood of potentially harmful chemicals
  5. Maintain intravascular fluid volume – Colloidal ONCOTIC PRESSURE (Albumin)!
  6. Produce bile
  7. Remove damaged or old erythrocytes to recycle iron and protein (this cycle produces the waste product bilirubin).
  8. Serve as a blood reservoir-VERY VASCULAR

Q

Involuntary vomiting sequ

A

A deep breath is taken.
The glottis closes and the soft palate rises.
Respirations cease to minimize the risk of aspiration.
The gastroesophageal sphincter relaxes.
Abdominal muscles contract, squeezing the stomach against the diaphragm and forcing the chyme upward into the esophagus.
Reverse peristaltic waves eject chyme out of the mouth.

A

The lining of your esophagus is more delicate than the lining of your stomach. So, the acid in your esophagus causes a burning sensation in your chest.

128
Q

Constipation (symptom)

A
Change in bowel pattern characterized by infrequent passage of stool in reference to the individual’s typical bowel pattern
Causes:
Low-fiber diet
Inadequate physical activity,
Insufficient fluid intake,
Delaying the urge to defecate,
Laxative abuse
Stress
Travel
Bowel diseases
Chronic constipation also greatly increases the patient’s risk of colon cancer!
129
Q

A

pain during the passage of a bowel movement,
inability to pass stool after straining or pushing for more than 10 minutes,

decreased bowel sounds from decreased peristalsis.

130
Q

Constipation treatment

A

increasing dietary fiber
increase in hydration

A

Usually sudden and severe
Classical manifestation = abdominal rigidity (hardening)

Nausea and vomiting
Decreased peristalsis
Intestinal obstruction
Indicators of infection (e.g., fever, malaise, and leukocytosis)
Indications of sepsis and shock

137
Q

Loss of fluid in the GI Tract

A

Turnover of fluid in the bowel is large; about 9 to 10 liters
of fluid enter the gut each day:

Water Turnover in the Bowel
Water from diet
2000-3000 mls/day
Saliva
1000-2000
Gastric juice
1000-2000
Bile
500-1000
Pancreatic juice
1000-2000
Intestinal secretions
1000-2000
138
Q

Inflammatory Bowel Disease (IBD)

A

Chronic inflammation of the GI tract, usually the intestines
Includes Crohn’s disease and ulcerative colitis
Exacerbations and remissions
Thought to be caused by a genetically associated autoimmune state that has been activated by an infection
Fluid, electrolyte, and pH imbalances develop
Can be painful, debilitating, and life threatening
Cause malabsorption of nutrients, leading to multiple problems

139
Q

Crohn’s Disease

A

Insidious, slow-developing, progressive condition
Often develops in adolescence
Manifestations:
Abdominal cramping and pain (typically in the right lower quadrant)
Diarrhea
Constipation
Abdominal mass
Melena
Anorexia and weight loss
Indications of inflammation (e.g., fever, fatigue, arthralgia, and malaise)
Strictures, fissures, abscesses occur

140
Q

Ulcerative Colitis

A

Progressive condition of the rectum and colon mucosa
Usually develops in the 2nd or 3rd decade of life
Manifestations:
Diarrhea (usually frequent [as many as 20 daily]
Watery stools with blood and mucus
Abdominal cramping
Nausea and vomiting
Weight loss
Indications of inflammation (e.g., fever, fatigue, arthralgia, and malaise)

141
Q

Stages of stomach cancer

A

Stage 0-4

142
Q

Irritable Bowel Syndrome (IBS) manifestations

A

Chronic and frequent constipation or diarrhea, usually accompanied by pain
Non-bloody stool that may contain mucus
Bowel urgency
Emotional distress
Anorexia

143
Q

A

Conditions related to the development of diverticula, outwardly bulging pouches of the intestinal wall that occur when mucosa sections or large intestine submucosa layers herniate through a weakened muscular layer

144
Q

Diverticulosis

A

Asymptomatic diverticular disease - chronic

Usually there are multiple diverticula present

145
