Exam 4 Flashcards
Cancer risk factors
smoking, alcohol, obesity, oral contraceptive use, diet high in fat and low in fiber, uncontrolled DM, frequent sun exposure
Cancer prevention-primary
diet high in fruits and vegetables and complex carbohydrates, exercise, smoking cessation, control weight, stay out of the sun during peek hours and use sunscreen daily, PPE at work
Cancer prevention-secondary
Self examination practices: skin(annually by provider), oral cavity(dippers), lymph nodes, breasts(Once a month after period)/chest walls, testicles(in shower, once a month), penis
Cancer prevention-tertiary
Screening test:
Mammogram, PSA levels, prostate exams, papsmear (21 y/o and every 3 hours if normal)

ASAP- young age
When is secondary cancer prevention started?
ASAP-never too young
When is tertiary cancer prevention started?
Mammogram at 40 and then annually (high risk individuals= 35), PSA at 50 and then every 2-3 years (high risk at 40), prostate exam 55-69 y/o
Lung cancer review
If not a smoker, radon is #1 cause
Heavy smokers= small cell carcinoma (oat-cell(
Non-small-cell carcinoma(bronchogenic carcinoma)= most common type of malignant lung cancer

Breast cancer S/S
Most common malignancy in women, second leading cause of cancer death in women
-asymptomatic, mass in breast or Axillary that is hard, uneven edges, usually painless, change in size, shape, feel of breast in nipple, nipple drainage that may be bloody, clear to yellow, green, or purulent
Breast cancer risk factors
Rates higher in Caucasian women, African American women more likely to die
Age, early onset of menstruation, family Hx, genetic predisposition (BRCA1,BRCA2), obesity, chest wall radiation, excessive alcohol cosumption, exogenous estrogen exposure
Breast cancers are
Estrogen dependent (mostly), originate in duct system, may arise in lobules, early the tumor is freely moving, tumor becomes fixed as cancer progresses
Metastasis occur to nearby lymph nodes, lungs, brain, bone and liver
Skin cancer risk factors
Males, Caucasian, fair complexion, family Hx, UV exposure (natural or artificial)= most significant risk factor
Skin cancer types
Basal cell carcinoma (most common), rarely metastasizes
Squamous cell carcinoma (middle layer of epidermis)
Melanoma (melanocytes), least common type but most serious, often metastasizes
Skin cancer appearance
Small, shiny, waxy, scaly, rough, firm, red, crusty, bleeding
-asymmetry, border irregularity, color variations, diameter larger than 6mm, any skin growth that bleeds or will not heal, any skin growth that changes in appearance over time
Prostate cancer
Most common cancer in men, particularly African Americans
-slow growing with unknown cause, obstructs urethra
Prostate cancer risk factors
History of STI’s, family Hx, high-fat diets, androgen hormone replacement, African american
Prostate cancer S/S
Urinary difficulties, erectile dysfunction, bloody semen, hematuria
Acute myeloid leukemia (AML)
Unknown cause, rarely occurs before 40, peaks at 67 y/o
-immature myeloblasts in bone marrow
-WBC may be low, normal, high
Prognosis depends on pt
S/S AML
Result from insufficient blood cells
-fever and infection (neutropenia)
-fatigue and weakness (anemia)
-bleeding tendencies (thrombocytopenia)
-painful enlarged liver/spleen(engorgement)
-hyperplasia of gums

AML Dx and tx
CBC: dec RBC and PLT
BMA: excessive immature blast cells sitting in marrow
Tx: induce remission
Aggressive- cytarabine
Elderly pts can take hydroxyurea
BMT last resort
Tumor Lysis syndrome
Complication of cancer treatment
large amounts of tumor cells destroyed and components in blood stream
-hyperuricemia,hyperkalemia,hyperphosphatemia, hypocalcemia
Nurse role:
Monitor for bleeding, infections, pain, end of life issues
Chronic leukemia
Less likely to be terminal
Two types:
Chronic lymphocytic leukemia
Chronic myelogenous leukemia
Chronic leukemia…
Progresses more slowly
-longer life expectancy
-cells better differentiated
-unknown cause
Link between Epstein Barr virus
Predisposition in families
Chronic lymphocytic leukemia
Older person (>72 usually)
-malignant transformation of B cells
“B symptoms”: fevers, night sweats, unintentional weight loss, and infections
CLL S/S
Weak, fatigue, painful lymphadenopathy
Anemia
Thrombocytopenia (depending on stage)
Enlarged spleen
Elevated WBC
CLL Dx and tx
Bone marrow biopsy
Tx not started until S/S appear severe
Not curable, only induce periods of remission
-combo therapy
-radiation to thymus, spleen, entire body
-older person have heightened risk of second malignancy with radiation
CLL progression requires…
Nutritional support, pain control ,skin care, emotional support
Chronic myelogenous leukemia
Overproduction of abnormal myeloid/blast
-uncontrolled proliferation of granulocytes
-causes bone marrow and organs to enlarge (pain)
Risk dramatically increases with age, if in chronic stage life expectancy >5 yrs
No known cause except ionizing radiation
CML S/S
Philadelphia chromosome- good Dx marker in 95% pts
-asymptomatic with leukocytes is
Classic chronic symptoms:
-fatigue, weakness, anorexia, weight loss, splenomegaly
-SOB, confusion with high leukocyte counts
-hepatomegaly, but functional
-fever and adenopathy in blast stage
WBC 15,000-500,000
Tx CML
Therapeutic blood draws to draw out some WBCs (dec blood viscosity)
Goal= control proliferation of WBC/induce remission
-bone marrow transplants
-leukophoresis (>300,000)
-hydroxurea
Nursing care for pts with leukemia
Know potential effects of leukemia and of tx and assess
-manage mucositis
-control pain and discomfort
- risk of dehydration
-weakness and fatigue (fall risk)
-rest between activities
-assist with self care
- anxiety/grieg
-hospice/ home health
Hodgikin’s lymphoma
More common in immunosuppressant pts
Reed-sternburg cells
Hodgkin’s lymphoma S/S
First sign= enlarged cervical node
-one or more enlarged painless lymph node(s)
“B” symptoms
-fatigue, pruritus, early mild anemia then worsens and accompanies with weight loss (poor prognosis)
-inc ESR, leukocytosis eosinophilia, leukopenia, PLT normal
-impaired cellular immunity so dec response to skin testing
Multiple myeloma
Worst cancer, most aggressive
5 year survival for new Dx pts
Infiltrates bone marrow and aggregates into tumor masses in skeletal system
MM presentation
Bone pain , bone lesions (destruction of bone tissue, inc calcium form reabsorption of bone by osteoclasts)
RF secondary to hypercalcemia
Anemia d/T inhibited erythropoiesis
MM S/S
Pathological fx
Back pain/ribs pain
Repeated infection form suppressed humoral response (pneumonia/phyelonephritis)
-fever wight loss, night sweats, breakdown of bone can lead to RF
Dx of multiple myeloma
Blood test, sudden inc in protein in blood/urine
CRAB
C=elevated calcium (bone breakdown )
R=renal insufficiency
A=anemia
B=bone lesion
BMA
X-ray
Nuclear bone scan
tx of MM
No cure, poor prognosis
Chemo-treat immediate and high grade
Radiation
Plasmapheresis-when blood viscosity is high
-mostly end of life care
Caution-cancer
Things to look out for
C=change in bowel and bladder habits
A= A sore that does not heal
U= Unusual bleeding or discharge (women after menopause should NOT bleed)
T= thickening or a lump in breast or elsewhere
I= Indigestions or difficulty swallowing
O= Obvious change in wart or mole
N=nagging cough or hoarseness
Major treatment modalities- chemo
Systemic form of tx->destroys greatest number of cancer cells (goal= w/o irreversible damage to normal cells)
- destroys rapidly growing cells; interferes w/ cell growth and division
-nurse must be educated to administer
-same nurse who prepares dose does not administer
-another nurse must check MD order and IV contents
Major treatment modalities-radiation
Damage cancer cells during different phases of cell division
-duration= once/day for 5 days for 2-8 weeks (must give cancer cells time to reoxygenate)
-internal/external
Markings made on skin (with marker to mark location-most precise)
External radiation
Treat superficial lesions and deeper structures
Skin care: inspect for redness, ask about changes in sensation
No lotions, ointment, powders, or soaps
Do not wash off skin marking
internal radiation
Brachytherapy- high dose to localized area via implants, needles, seeds, beads, catheters
Pt=reverse isolation- protect pts and visitors (pt emits radiation)
S/e of tx- neutropenia
Depleted WBC, high risk of infection
-chemo not given if ANC= <1,500/cmm
-precautions for ANC= <1,000/cmm
-avoid animal contact
-no rectal exams/procedures
-no fresh flowers
-private room desirable
-use fresh ground pepper
-low microbial diet
- reverse isolation if ANC= <500
-STRICT HANDWASHING BY ALL STAFF AND FAMILY
S/e of tx of thrombocytopenia
Depleted platelets, high risk of bleeding
-chemo not given if PLT= <100,000cmm
-hold all sticks for 5 min
-use electric razors only
-no rectal temps, enemas, suppositories, or examinations
-no IM injections
-use stool softeners (avoid straining)
-no aspirin or aspirin-containing products/anticoagulants
-observe daily for petechia, ecchymosis, hematuria and inc ICP
Common physiologic complications-superior vena cava syndrome
Most often associated with lung cancer, lymphoma, metastases
-compression.invasion of SVC by tumor, enlarged lymph nodes
SVCS
Superior vena cava syndrome-oncologic emergency
S/S SVCS
Progressive SOB, cough, facial swelling, edema of neck, arms, hands, thorax, tightness and difficulty swelling, engorged and distended jugular
management of SVCS
Radiation-shrink tumor and relieve symptoms
-chemotherapy, oxygen therapy, anticoagulant therapy, diuretics
Nursing care for SVCS
Identify at risk pts
-check CV and neuro status
-position for easier breathing, minimize energy expenditure
-watch fluid balance, admin fluids with caution
-assess for dysphagia, esophagitis r/t radiation
Common physiologic complications-tumor lysis syndrome
Develops when cytotoxic therapies (chemo/irradation) cause destruction (lysis) of large number of rapidly dividing malignant cells
-lysis of fast growing cells is greater than the body’s capacity to excrete the end-products of cell death
What is released when cells die
Potassium,phosphorus, nucleic acids into general circulation
-results in hyperkalemia, hyperuricemia, hyperphosphatemia w/ secondary hypocalcemia
-puts pt at risk for renal failure and alterations in cardiac function
How is superior vena cava syndrome treated
Radiation to shrink tumor and relieve symptoms, chemotherapy, oxygen therapy, anticoagulative therapy, and diuretics
Fluid management for superior vena cava complication
Electrolyte imbalances, administer fluids with caution, assess for dysphagia, esophagitis r/t radiation
EOL management for superior vena cava complication
Manage pain and symptoms, oxygen therapy , prevent bleeding with anticoagulant therapy and prevent infection.
What meds are used in tumor lysis syndrome
Allopurinol(urinary alkalization, prevents kidney stones and kidney damage leading to RF)
Client education-tumor lysis syndrome
Hydration is IMPORTANT, keep UOP at least 150mL/hr
Allopurinol given orally 2-4 days prior to chemo
Osteoporosis
Porous bones, osteoclast activity greater than osteoblast activity leading to a decrease in bone density/mass-> risk for fx
