Q

intestinal obstruction

Study These Flashcards
A
  • flow of intestinal contentes is blocked
  • sbo: small bowel obstruction
  • lbo: large bowel obstruction

mechanical:

  • blockage occurs within the intestine
  • tumor adhesion
  • as a result of something putting pressure

non- mechanical

  • peristalsis is impaired
  • partial or complete
22
Q

intestinal obstruction clinical manifestations

Study These Flashcards
A
  • abdominal pain
  • blood and mucus per rectum
  • feces and flatus cease
  • fecal committing may occur
  • bowel sounds high pitched/ tinkling or absent
  • abdominal distention
  • fluid/ electrolyte imbalance
23
Q

appendicitis’s

Study These Flashcards
A

inflammation of appendix

patho

  • infection triggers localized edema
  • fluid builds inside the appendix
  • appendix fills with purulent exudate
  • pressure inside the appendix escalates causing reputure
24
Q

appendicitis’s clinical manifestations

Study These Flashcards
A
  • fever
  • pain
  • n/v
  • anorexia
  • pressure make it better
  • check for rebound tenderness
25
peritonitis
- inflammation of infection of peritoneal cavity - system wide infection - thick sticky exudate that bonds nearby structures and temporally seals them off - peristalsis may slow down in a response to the inflammation, decreasing spread of toxins, bacteria
26
peritonitis signs and symptoms
- abdominal pain - abdominal rigidity - nausea/ vomiting - fever need antibiotic iv fluid
27
chrons
inflammatory bowel disease - any part of the intestine - remissions and exacerbations - slow developing often develops in adolescence - intestinal wall a cobblestone appearance - decreased ability to digest and absorb etiology - unknown - hereditary
28
chrons clinical manifestation
- abdominal pain or cramping - weight loss - diarreha - fluid and electrolyte imbalance
29
ulcerative colitis
inflammatory bowel disease - progressive conditon: more serve autoimmune - usually develops in 20s- 30s - inflammation causes epithelium loss, surface erosion, and ulceration - affects large intestines and rectum
30
ulcerative colitis clinical manifestations
- ab pain - 5 to 20 stools daily, 30-40 times - rectal bleeding - fecal urgency - anorexia and weight loss - cramping - dehydration - difficultly maintaining jobs/ school
31
diverticular disease
diverticulum=1 - out pouching of bowel mucous membrane - happens as a result of bowel weakening from low fiber diet and poor bowel habits such as chronic constipation diverticulosis- does not cause symptoms - multiple diverticula diverticulitis- something lodged in hole - inflammation/ infection of diverticulum
32
diverticular disease
- diarrhea/ constipation | - cramps/llq pain: comes and goes
33
colorectal cancer
cancer or large intestines or recum etiology - lack of dietary fiber - ulcerative colitis - family hx clinical manifestations - change in bowel habits - blood or mucous in stools - abdominal or rectal pain - weight loss - anemia - obstruction - reastomic- put colon back together
34
gallbladder disorders: - cholecystitis - cholelithiasis - choledocholithiasis
three disorders - cholecystitis- inflammation of galbladder - cholelithiasis- stones - choledocholithiasis- stones in CBD- common bile duct (first two happen independtly)
35
gallbladder disorders risk factors
- age - obesity - diet (increase fat, increase cholesterol, decrease fiber) - pregnancy: after delivery= change in nutritional status - chronic diseases (of hypatbillary system)
36
gallbladder disorders clinical manifestations
- biliary colic- specific pain in RUQ radiates to shoulders and back after fatty meal - RUQ pain - n/v when stone lodged: - jaundice - chronic disease
37
hepatitis
inflammation of live etiology - viral or bacterial infections - drugs - alcohol - hepatotoxic drugs - metabolic/ vascular disorders
38
hepatitis types
- HAV- most common transmitted tru frcal oral route - HBC- transited thru blood, sexually transmited fluids: blood, stool, urine, saliva - HCV- transmitted thru blood, Iv drug use (not really seen anymore) use to associated with blood tranfusions - HDV- extremely rare - HEV- extremely rare
39
hepatitis prevention
- hand hygiene | - vaccines: hav, hbc
40
hepatitis symtoms
prodromal stage: 1 week - flu like symptoms: 1 week icteric stage: 2 to 6 weeks - jaundice, worsening symptoms convalescent: 2 to 6 weeks - returning to normal liver function (don't need to know)
41
cirrhosis
progressive, irreversible replacement of healthy tissue with scar tissue - 12th leading cause of death in US
42
cirrhosis etiology
- chronic alcohol use- most common - hepatotoxins drugs - hepatitis- left untreated - gallbladder obstruction- prolonged - heart failure
43
cirrhosis patho
- inflammation of liver cells - infiltration with fat and wbc - fibrotic scar tissue replacements liver tissue - abnormal regeneration - impaired liver blood flow and function
44
cirrhosis complication
- clotting defects - encephalopathy: elevation of ammonia portal hypertension - varices: enlarged vessels- risk for rapture: coughing/ vomitting can cause repture - ascites: fluid accumulation in addomen: fluid not being held in vascular system
45
pancreatitis
acute or chronic inflammation of pancreas patho: - autodigestion: pancreatic enzymes - pancreatic tissue is replacement by fibrosis: dysfunction of the islets of langerhans: exocrine and endocrine change
46
pancreatitis etiology
alcohol biliary disease trauma certain drugs
47
pancreatitis manifestations of acute pancreatitis
- sudden and severe - upper abd pain worsens after eating g - nausea and vomiting - mild jaundice - low grade fever - blood pressure and pulse changes
48
pancreatitis manifestations of chronic pancreatitis
- upper ab pain - ingestion - losing weight without trying - steatorrhea- oily/ fatty stool (floating poop) - constipation - flatulence
49
liver cancer
ca of the liver - commonly occurs as secondary tumor risk factors - chronic hepatitis - alcoholism - hepatotoxins clinical manifestations - similar to hepatitis and cirrhosis
50
pancreatic cancers
ca of the pancreases - metasiszes quickly risk factors - smoking - obesity - dm - pancreatitis - alcoholism - diet increase red meat clinical manifestations - weight loss - abd pain - n/v anorexia - jaundice
