GI AP Feed UGI Flashcards
What is the best position to give enema?
left lateral d/t the positioning of sigmoid colon
What might happen is the vagal nerve is simulated?
decrease HR and BP
For what conditions is rectal temperature contraindicated?
Cardiac disease such as MI r/t risk of brady arrythmias, recent rectal, vaginal and prostate surgery r/t surgical incision
Liver function
Synthesis of glucose, protein & blood-clotting factors
Produces bile to digest and absorb fats
Should not be able to palpate
Kupffer cells
phagocyte bacteria that enters the liver
pancreas function
Endocrine: insulin, glucagon, somatostatin
Exocrine: secrete pancreatic enzymes into GI tract through pancreatic duct (amylase, lipase, trypsin)
Spleen function
Filters antigens from the blood
Removes old or abnormal RBCs
Responsible for the immune response to infection because it is rich with B and T lymphocytes
Gallbladder functions
Storage tank for bile
Bile salts emulsify fat in the distal ileum
What is bilirubin converted to
urobilinogen and either excreted in feces or returned to portal circulation where it is re-excreted into the bile
What happens when bile is impeded due to gall stones or tumor?
Biliruben does not enter the intestine
- jaundice
- Icterus
- Renal excretion of the bilirubin (dark color urine)
- —-> Frothy when agitated since bile is a soap
- Clay colored stools because bile is not entering the small intestine
- Pruritus
- —-> Bile salts are irritating to the skin
Gero: Oral cavity, pharynx, esophagus
Chewing swallowing
Reflux (heartburn)
Decreased peristalsis
Gero: Stomach, small intestine, large intestine
Gastric mucosal degeneration
Decreased HCL production
Decreased B12 absorption leads to anemia)
Loss of sphincter control
Gero: liver
Increased drug toxicity
Decrease phagocytosis by Kupffer cells
What are things you want to consider when performing an abdominal assessment?
Hepatoxic substances Pain Dyspepsia Gas N/V Bowel habirs Color/consistency (BM, emesis) Soft, flat, rounded/soft, rounded/firm Jaundice Ascites Vein enlargement
What order of business do we use when doing a physical examination of the abdomen?
Inspection
Auscultation
Percussion
Palpation
Cullen sign
Bruising around umbilicus
- often seen in pancreatitis
Murphy sign
Patient unable to take a deep breath when examiners fingers are pressed below the right costal margin
Blumberg sign
Rebound tenderness
– seen in peritonitis
Rectal examination is done when?
usually performed when someone has fecal impaction
Dx: stool
multiple dif. tests for stool
Dx: Breath
H. Pylori (bacteria that can invade stomach)
Dx: imaging - upper GI tract study - barium swallow
Barium becomes like concrete in the GI tract - it will discolor stool. Push fluids and stool softener after
can inject through ostomy or rectum as well as PO
Endoscopy
Direct visualization of structure through a lighted endoscope
Gastric pH and esophageal pH ranges?
Gastric pH: 1-2
Esophageal pH: 5-6
