A

irritating substances (alc)
drugs (NSAIDs)
infectious agents (H.pylori)

27
Q

chronic gastritis

A

progressive disorder with chronic inflammation in the stomach

28
Q

complications of chronic gastritis

A

PUD
bleeding ulcers
anemia
gastric cancers

29
Q

A

1) autoimmune -> attacks the parietal cells
2) H.pylori infection

30

what can H.pylori cause

A

chronic gastritis
PUD
stomach cancer

31
Q

how is H.pylori transmitted

A

-person to person via salvia, fecal matter or vomit
-contaminated food or water

32
Q

acute or chronic gastritis sx

A

anorexia
N/v
postprandial discomfort
intestinal gas
hematemesis
tarry stools
anemia

33
Q

acute gastroenteritis

A

inflammation of the stomach & small intestine

34
Q

acute gastroenteritis etiologies

A

1) viral infections- norovirus & rotavirus

3) parasitic infections

35
Q

acute gastroenteritis clinical manifestations

A

-watery diarrhea (possibly w/ blood if bacteria)
-abdominal pain
-N/v
-fever, malaise

36
Q

acute gastroenteritis complication

A

fluid volume deficit because of mass amount of diarrhea

37
Q

acute gastroenteritis treatment

A

let the patient right it out but may need to give fluids

38
Q

when does PUD develop

A

when the GI tract is exposed to acid and h. pylori
(+NSAIDs, ASA, Alc)
+smoking
+stress bc inc gastric acid is a stress response

39
Q

why can NSAIDs induce PUD

A

they inhibit prostaglandins synthesis so the upper GI loses the mucus coating

40
Q

PUD clinical manifestations

A

-N/v
-anorexia
-wt loss
-bleeding
-burning pain (middle abdomen)

duodenal ulcer

A

CM: burning, cramping, gas like
location: epigastrium, back
timing: 2-4 hrs after eating

43

complications of PUD

A

hemorrhage
obstruction
perforation / peritonitis

Q

complications of appendicitis

A

gangrene
abscess formation
peritonitis

45
Q

key points of appendicitis

A

-RLQ pain
-rebound pain
-sudden relief of pain if it ruptures

46
Q

peritonitis

A

inflammation of the peritoneum that causes 3rd spacing which can lead to hypovolemic shock, sepsis, & decreased peristalsis -> paralytic ileus

47

48
Q

vitals/labs seen during peritonitis
