Hematology Flashcards
Anemia
Dec. RBC, Blood Loss, Inc. RBC destruction
- Deficient nutrients (iron/folic acid), Dec. erythropoietin, dec. iron availability.
- Chronic versus Acute (duodenal ulcer/liver disease versus acute trauma)
- HGB
Manifestations of Anemia
Tissue Hypoxia In effect of how quickly anemia occured. Mild: 10-12 Mod: 6-10 Severe: 0-6
Skin-pale and jaundiced and puritis and cold
Cardio-tachycardia, inc. pulse pressure, HF, claudication
Iron Deficiency Anemia
Gi patients
Chronic Kidney
GI bleeds
Manifest: sx later on, lips and tongue swell.
Dx: Hgb & Hmct
Endoscopy/Colonoscopy
Implement: bleed=cauterize, nutrient=iron dense food! (beans), take with orange juice…better absorbed. Laxative.
Evaluation: hgb? 2-3 months to go back to normal.
Anemia of Chronic Disease
1-2 months after disease, underproduction of RBC.
becomes
Anemia of inflammation…cancer, infectious disease, hepatitis, TB,
Dx-underproduction of RBC…usually mild…1-2 months after.
Implementation: treat underlying condition.
Evaluation: Labs
Aplastic Anemia
Peripheral blood pancytopenia and drop in platelets. Deadly.
Caused by autoimmune disorder…caused by medications and radiation.
Manifest: Happens over a few days or flowly.
Signs of bruising, neutropenia, bleeding, fatigue,
Dx: check labs!
Risk for bleeding and infection
Implementation: Identify and prevent….hematapoetic stem cell transplant or steroids.
Eval: WBC, hgb, platelets.
Anemia caused by blood loss
Assoc. with shock/surgery/hemorrhage.
Signs: Clammy cool skin,
Dx: Hgb, WBC, platelet
Do: Restore fluid, albumin, add volume, iron supplements,
Thrombocytopenia
BLEEDING AND BRUISING.
Worst case- brain bleed….internal bleeding anywhere.
Prolonged bleeding anywhere.
Dx- platelets below 20,000 (spont. bleed), below 10,000 (transfusion).
Massive bleeding- body will try to stop and overly produce thrombosis and then you have clotting.
Ddimer is a common dx.
Risk for bleeding
Deficient knowledge.
Impaired tissue perfusion.
Planning- vascular integrity and no bleeding.
Implementation: no aspirin or NSAIDS. Black tarry stools. Blacck vomit Blood in urine Abnormal bleeding Bruising Sudden headache (911) Prevent falling/no contact sports. If bleed = apply pressure for 10 min. No razor...gentle flossing and blowing nose. No suppositories/rectal temp! (don't damage rectal mucosa.
Prevent constipation and bleeding!!
Hgb, Hmct
ITP
Immune Thrombocytopenia!
- Most common acquired.
- Body attacks itself, destroys platelets.
- Steroids
TTP
Thrombotic Thrombocytopenic Purpura
- Uncommon
- Anemia associated
- fever, no infection, renal abnormalities.
- caused by medication
- women prego…
- dangerous d/t clotting and bleeding.
Treatment: remove causative agent. Steroids, plasma pheresis.
HIT
Heparin-Induced Thrombocytopenia.
- r/t long term use of heparin.
- Thrombosis element.
- Monitor platelets before giving heparin.
- DVT–>PE
- NEVER get heparin again.
Neutropenia
Neutropenia-form of WBC.
Theme: pt. can’t fight infection and is at HIGH risk for infection. Leukopenia is drop in all WBC but neutropenia is a form of a WBC called neutrophils (phagocytosis).
Neutropenic-isolation!!
-Consequence of something else…chemotherapy, immunosuppressant therapy,
@ Risk if you…. have a fever, and abnormal flora.
Low-grade fever & neutropenia = medical emergency > 100.4
DX Blood culture from 2 sites of body BEFORE infusing antibiotics. Sore throat, diarrhea, SOB, cough,
WBC <4,000
neut<1,000
ANC <500 (actual neut)
Bone marrow Aspiration? Throat culture!
*Risk for infection
Intervene: start antibiotic therapy, get cultures. HAND hygiene, monitor signs/sx… screen visitors for infection. Educate pt. to contact provider if fever is over 100.4 and educate family on hygiene, avoid alcohol mouthwash (dry out mouth), no unwashed fruit or seafood or unwashed veggies or moldy cheese.
