White Blood Cells Disorders Flashcards
1
Q
Leukemia - Pathophysiology
A
-
Uncontrolled WBC production
> Cx occurs in stem cells of bone marrow; overcrowded w/ nonfunctional cells - Overproduction of Blasts cells (immature WBC)
- Exact cause unknown: many genetic & envir’t facotrs involved
> 50% of pts have abnormal chromosomes -
Normal cell production DCRD
> Pancytopenia: CMs; neutropenia, anemia, thrombocytopenia infiltration tissue/organ
2
Q
Leukemia - Classifications
A
-
Acute
> sudden onset abnormal blood cells -
Chronic
> abnormal cells replicate slowly -
Classified by Cell Type
> Lymphoid cells: Lymphocytic
> Myeloid cells: Myelogenous
3
Q
Acute Leukemia Types
ages
A
-
Acute Lymphocytic Leukemia (ALL)
> most common type in young children -
Acute Myelogenous Leukemia (AML)
> most common type in all adults
4
Q
Chronic Leukemia Types
ages
A
-
Chronic Lymphocytic Leukemia (CLL)
> most common chronic adult leukemia -
Chronic Myelogenous Leukemia (CML)
> asymptomatic for yrs before entering a fast growth phase
5
Q
Leukemia - Risk Factors
A
-
Prior exposure chemotherpay or ionizing radiation
> prevous cancer - Bone marrow hypoplasia
-
Genetic factors
> downs - Immune deficiency
- Virus
6
Q
Leukemia - Diagnosis
A
-
CBC
> abnormal WBC; high blast cells poorer prognosis
> low Hgb & Hct and platelets -
Bone Marrow Biopsy
> definitive test - Chromosome analysis
- Other X-rays, CAT scans, MRI
7
Q
Leukemia - CMs
psychological
lymph nodes
spleen/liver
A
-
Psychological
> fatigue
> loss of appetite -
Lymph Nodes
> swelling -
Spleen and/or Liver
> enlargement
8
Q
Leukemia - CMs
skin
systemic
A
-
Skin
> night sweats
> easy bruising & bleeding
> purplish patches or spots -
Systemic
> weight loss
> fever
> frequent infections
9
Q
Leukemia - CMs
lungs
muscular
bones/joints
A
-
Lungs
> easy SOB -
Muscular
> weakness -
Bones or Joints
> pain or tenderness
10
Q
Leukemia - Diagnosis: Bone Marrow Aspiration
A
- Provides info abt blood cells & production
-
Nursing
> teach pt what to expect
> position: prone or side-lying
> sedative provided
> local anesthetic injected -
Follow-Up Care
> control bleeding
> inspect site every 2hrs
> pain control
11
Q
Leukemia - Medical Treatment
A
-
Induction Therapy
> intense chemotherpay started as soon as diagnosis confirmed
> hospitalized 2-3wks in protective isolation
> Side Effects: severe bone marrow suppression, alopecia, N/V, stomatitis, organ toxicity -
Consolidation Therapy
> after recovery
> repeat drugs or bone marrow transplant -
Maintenance Therapy
> months to yrs to maintain remission
12
Q
Lymphomas
A
- Cancer of lymphocytes
-
2 main types:
> Hodgkin’s Lymphoma (HL): “curable”, teens & adults in 50-60s
> Non-Hodgkin’s Lymphoma (NHL): “non-curable”, all other lymphomas (over 60 types), older adult men
> many subtypes of both
13
Q
Palpable Nodes
cervical
A
-
Cervical
> posterior cervical
> pre-auricular
> upper cervical
> median or lower cervical
> supraclavicular
14
