What are the 5 cardinal signs of inflammation? ✅heat, redness, swelling, pain, loss of
function
Function of the inflammation response: ✅Restitution of normal, functioning cells after
injury.

activation, and plasma clotting that attract white blood cells to the area.
Chronic inflammation systemic response= ✅-Neutrophilia
-Fever
-Malaise
-Loss of appetite
-Muscle catabolism
-Liver activates compliment system
In chronic inflammation how does tissue repair and healing occur? ✅Macrophages
typically will remove necrotic tissue and pathogen from the tissue - repair and healing
can occur
In chronic inflammation, how can tissue healing get interrupted? ✅by renewed injury or
reinjury causing a reactivation of the cycle without completing it.
What are consequences of an excessive or ineffective inflammatory response? ✅-
Local tissue damage from compression
-Development of chronic inflammation
-systemic: atherosclerosis, chronic renal disease, neurological disorders.

very old
uninsured
Individual: autoimmune, allergies, pathogen exposure, chronic disease, lack of proper
sanitation.

XRAY,US,CT
Pregnancy test (maybe for women of childbearing age to rule out ectopic pregnancy
and before x-rays are obtained)
C-reactive protein.
C-reactive protein ✅Protein produced by the liver when bacterial infections occur and
rapidly increases within the first 12 hours.

count shows an elevated WBC count, with an elevation of the neutrophils.

FVD
, Risk for infection
Goals for a patient with appendicitis= ✅Relieve pain

IBD (inflammatory bowel disease) ✅inflammation of the colon and small intestine.
is a term for two conditions (Crohn's disease and ulcerative colitis) that are

inflammation results in damage to the GI tract.
What abnormal response does IBD create in the body's immune system? ✅Mistakes
food, bacteria, and other materials for foreign substances.
IBD causes Increased WBC= ✅chronic inflammation
Chrohn's disease affects which part of the GI? ✅It can affect any part of the GI tract.
most often it affects the portion of the small intestine before the large intestine/colon.
inflammation may reach through the multiple layers of the walls of the GI tract.
Ulcerative colitis affects what part of the GI? ✅The large intestine (colon) and the
rectum.
inflammation only present only in the innermost layer of the lining of the colon.
Ulcerative colitis (UC): ✅A chronic condition of unknown cause usually starting in the
rectum and distal portions of the colon and possibly spreading upward to involve the
sigmoid and descending colon or the entire colon. It is usually intermittent (acute
exacerbation with long remissions), but some individuals (30%-40%) have continuous
