✅FINAL Flashcards
Wa are the two different phases of inflammation?
Vascular phase
Delayed phase
Vascular phase
Histamine is release, which causes vasodilation which allows all of the healing products and blood to get to the area
Occurs 10-15 mins post injury
Vasodilation, capillary permeability increase, blood substances move from plasma to injury
Why causes swelling
Delayed phase
Leukocytes infiltrate the tissues and tries to ingulf all the dead tissues to. Get rid of them
What are the chemical mediators that are relased during inflammatory response?
Prostaglandins
Cyclooxygenase (COX-1, COX-2)
Prostaglandins
Part of the histamine response as well, causes vasodilation, relaxation of smooth muscle, ↑capillary permeability(so all of those healing products can through the site of injury/infection), ↑ pain sensation (allow body to feel pain)
Cycloooxygenase
There are cox-1 & cox-2
A shorter pathway that causes inflammation and pain as well
Medications are used to inhibit these
COX-1
Protects the stomach lining, regulates platelets
COX-2
Triggers inflammation and pain
What is the problem when we use a medication that inhibits COX-1?
GI upset, clotting problems because the platelets aren’t being regulated
GI ulcers/ bleeding
If someone has GI problems or bleeding, we would want to use a med that doesn’t inhabit COX-1.
We want to use a med to only inhibit COX-2, because we would want to protect the stomach.
What are the different types of Non-steroidal anti-inflammatory Drugs (NSAIDs)?
1st generation Salicylates:
Aspirin,Diflunisal (Dolobid)
Salicylate Derivatives:
Dipentum, sulfasalazine
Parachlorobenzoic Acids (Indoles):
Indomethecin(Indocin), Clinoril, Tolectin
Phenylacetic Acid: Voltaren, Voltaren XR, Toradol
Propionic Acid:
Nalfon, Ansaid, Motrin, Advil, Naprosyn, Daypro
Anthranilic acids. (Fenemates):
Meclomen, ponstel
Oxicams:
Feldene, Mobic
Naphthylalkanones:
Relefan
COX-2 Inhibitors 2nd generation NSAIDs:
Celebrex
(Remeber if we onlyinhibit COX-2, doesnt inhibits COX-1, this will help protect the stomach or causes less damage to the stomach while relieving pain and inflammation)
Aspirin (ASA)
Class: anti-inflammatory , analgesic
Salicylates prototype: Aspirin(ASA), Bayer, Ecotrin, Astrin
Also known as an Antiplatlet, decreases fever
Reduces inflammation & fever and inhibits aggregation of platelets
MOA: inhibit prostaglandins synthesis, inhibits COX 1&2 (so we need to worry about ulcers and gastritis because of inhibit of COX-1), inhibition of hypothalamic heat regulator center
What are the contraindications of using Asprin?
Remebr if anyone has an allergy to salicylate; should not be using
If anyone is allergic to aleve, Motrin, ibuprofen, should not be using asprin
In children that are younge than 13 yrs old, we do not give them asprin; could be deadly, organ failure,
Also shouldn’t use in pregenat omen in their 3rd trimester
Caution in those who has renal failure
what are the side effects of Asprin
N/V/D, dizziness, confusion, hearing loss, heartburn, rash, stomach pains, drowsiness, anorexia
Advers: *tinnitus (could be a sign of asprin toxicity), urticaria , ulceration
Life threatening: *hemolytic anemia, *bronchospasm and *anaphylaxis if they an allergy, *thrombocytopenia, hepatotoxity, leukopeniam agranulocytosis
Why would someone experience drowsiness with Asprin?
Bleeding; someone can experience slow bleeds;if someone is taking it everyday , lead to bleeds and they can experience drowsiness and fatigue. Anemic
What are the nursing considerations of Salicylates ASA, Ecotrin, Bayer, Astrin?
Do not take with ETOH (its very irritating to the stomach; at risk for ulcers)
Discontinue 5-7 days prior to surgery (if indicated; especially if they have cardiovascular disease; we will continue to take med)
Keep out of reach of children
Do not give to children with flu-like symptoms (Reyes
syndrome can cause death)
May cause GI upset: take with food
Report side effects such as drowsiness, tinnitus, HA,
flushing, dizziness, GI symptoms
Ibuprofen (Advil, Motrin)
Class: non steroidal anti-inflammatory (NSAID), Propionic Acid derivative
Very good inflammatory
They still inhibit COX-1, however they do not inhibit that much and not as acidic as Asprin; this can be be less upsetting for someone that has gastritis or hxs of ulcers
MOA: inhibition of prostaglandins synthesis, relieve pain and inflammation, *less GI effects than ASA
Therapeutic effects: to reduce pain anti inflammatory effect of arthritic conditions, reduces fever
What are the contraindications of Ibuprofen (Advil, Motrin)
Severe renal or hepatic disease, asthma, peptic ulcer
Can go into renal failure
Caution: bleeding disorders, pregnancy/lactation, SLE (systemic lupus)
What is the BLACKBOX warning with Ibuprofen (Advil, Motrin)?
Pts that have a hxs of cardiovascular disease or strokes; shouldn’t be taking this because it will increase risk of getting a stroke or heart attacks.
Side effects of Ibuprofen (Advil, Motrin)
N/V/D, anorexia, tinnitus , fatigue, dizziness,lightheadedness, anxiety, confusion, fluid retention with edema, rash
Take with food to avoid GI upset
Adverse: GI bleed
Life threatening: blood dycrasias, cardiac dysrhythmias, nephrotoxicity, anaphylaxis
What are the nursing considerations of NSAID’s (Ibuprofen)?
Observe for signs of bleeding especially with AC use
Take with food to reduce GI discomfort Avoid concomitant use with ASA and acetaminophen
Avoid ETOH to reduce ulcer risk
Inform dentist or surgeon of use prior or procedures
Do not take if pregnant or breast feeding
Celebrex
Class: NSAID COX-2 inhibitor
(Doesn’t inhibit COX-1; it’ll be better for pts with hxs of gastritis or stomach ulcers).

Lower incidence of GI distress than other NSAID’s
May take effect after 1-2weeks of using
We can usually use corticosteroids to help the pt feel better ; usuallly have to taper them off
Immunoladulator (tumor necrosis factor blocker)
Changes the immune response; use for pts that have autoimmune disorder; decreases the inflammatory response by descresing the immune response
Ex: rheumatoid arthritis
Infliximab (Remicade)
Class: immunomodulator

Gout
Inflammatory condition that attacks joints, tendons and other tissues
/ basically arthritis in the smaller joints (ex:big toe)
Most common site of attack is the great toe
Increased uric acid levels due to:
Uric acid metabolism disorder
Defect in purine metabolism
Appears as bumps (tophi) in Hands elbows and large toe
Can evolve into gouty arthritis, urinary calculi, gouty neuropathy
What to do when have gOUT

Cant be around people for weeks if they just received a live vaccine
Cant be aroud people
Use aseptic techniques
Cant be around people that are sick
RBC and WBCs can be destroyed because of meds, consider giving blood
N/v
What is the big picture for ALL AntiCancer meds?
Drop in WBCs RBC & platelets (we would worry about infections; always have good hygiene)
Worry about the IV site; can cause necrosis if infiltrate
Cardio toxicity
Pregnancy category D
Nausea, vomiting and diarrhea (may have to give an antiemetic or Antidiarrheal)
Cyclophosphamide (Cytoxan)
Class: AntiCancer med
The big picture to remember is Cytoxan causes hemorrhagic Cystitis
Think of “Cytoxan Cystitis”
Means the bladder gets inflamed and starts to bleed;
What do we tell pts who are taking Cytoxan?
To urinate frequently, so the metabolized meds are not sitting in the bladder. Also, drink lots of fluid to dilute their urine so it wont be so irritating to the bladder.
What do we have to MAINLY look out for with Cyclophosphamide (Cytoxan)?
cardio toxicity in HIGH doses
We have to watch the heart function via Echo
Nursing considerations of Cyclophosphamide (Cytoxan)
Assess CBC, plts (may hold med if levels are too low)
Handle drug with care( avoid direct contact with skin, eyes, mucous)
Monitor IV site frequently for irritation and phlebitis
Administer Anti-emetic 30-60 mins before giving Drug
Hydrate pt with IV and oral fluids prior to administration
Monitor bun/cr
Dont give the drug at night; nocturia
What do we teach the pt taking Cyclophosphamide (Cytoxan)?
Maintain good hygiene Take early in the day to prevent accumulation of drug in bladder at night Consult with oncologist before getting vaccines Drug is excreted in breast milk
Testicular atrophy and reversible oligospermia/azoospermia may occur in men Avoid pregnancy for 3-4 months after completing treatment Avoid others with respiratory infections Report signs of infection immediately

We have to worry about peripheral neuropathy
And loss of DTR (deep tendon reflexes)
Liposomal Chemotherapy
AntiCancer
New med
Packed in a fat capsule and taking orally’ slow release
Allows drug to remain the system longer, decreased side effects ; increased. Therapeutic effects
Corticosteroids
Class: hormonal angent
Help slow the growth of a tumor through anti-inflammatory effects /decrease the inflammation of the tumor; and that can help prevent the tumor from hurting so much
Give pts a sense of euphoria; gives them energy.
Bio therapy agents
Monoclonal antibodies
Vaccines
Monoclonal antibodies
Help treat against cancers
It recognizes proteins on specific cancer cells
Vaccines
Used to prevent ca
Ex: he B, Gradisil, Cervarix
Fluorouracil, 5 fluorouracil, 5-FU (Adrucil)
Class: antimetabolites; AntiCancer
Worried about tots getting cardiotoxicity as well
rituximab (Rituxan)
Class: monoclonal antibody; AntiCancer
Cardiotoxicity we worry a bout as well
Biological Response Modifiers
These are med that will helo us increase those blood cells that were destroyed during chemotherapy
Enhance host immunologic function Destroy or interfere with tumor activities
Promote differentiation of stem cells
Erythropoietin (Epogen, Procrit, Eprex)
Class: biological response modifiers
Originally produced in the kidneys
Help increase the RBC and WBC
while on chemotherapy
We dont try to get them back to normal Hemoglobin levels, just to level 10 no higher than 12 ; If increased too high, risk for MI/CVA
/
Serious cardiovascular and thromboembolic events if target Hemoglobin of 12g/dl exceeded
Neurogenic/Neulasta
Class: Biological Response Modifiers
Increase the WBC
May use for pts who has leukopenia while taking chemotherapy meds
What do you need to worry about with pts who are taking Epogen?
SOB, fatigue, HTN, and seizures
Life therenating : MI, CVA
Nursing considerations for erythropoietin (Epogen)
DO NOT SHAKE bottle, shaking may denature the preparation
Vial has no preservatives only one use per vial/ one time use vials
Use smallest amount per injection
Do not use the same needle to draw or put through the stopper and inject medication.
Change needle in between.
