Chemotherapeutic Drugs Biologic and Immune Modifiers Flashcards
Block hormone receptors on hormone-sensitive tumors to stop or slow cancer growth rate - specific cancers r/t some type of hormone
Used in treatment of breast cancer, prostate cancer, etc.
Cancers hormonal related
Cancer treatments: hormonal manipulation
Competes with estrogen binding sites in target tissue; antiestrogen - help growth cancer because r/t estrogen activty
MoA: - Hormone Modulators: Prototype: Tamoxifen
breast cancer; prophylactic breast cancer - certain breast cancers r/t hormonal activity: block hormones thus reduce cancer growth; specific cancer
Indications: - Hormone Modulators: Prototype: Tamoxifen
oral (may take for sev years) - may go through antineoplastic and may be on this drug for long-period time for number yrs after
Route: - Hormone Modulators: Prototype: Tamoxifen
r/t antiestrogen effects [blocking receptor sites] (menopausal like symps: needs much edu and if not gone through it: hot flashes, menstrual irregularities); Masculinizing effects in women; risk DVT
AE: - Hormone Modulators: Prototype: Tamoxifen
pregnancy; breastfeeding, anticoagulants; hx blood clots
Contraindications: - Hormone Modulators: Prototype: Tamoxifen
comfort measures to help client cope with menopausal signs and symptoms such as hygiene measures, temperature control, and stress reduction
Nursing: - Hormone Modulators: Prototype: Tamoxifen
Aka chemotherapy drugs
General
Goals of treatment
Caution
Routes
Antineoplastic agents
Harmful to all rapidly growing cells
Narrow therapeutic index/window:
Fine line between toxic & therapeutic levels - little margin of room; monitored closely; frequent lab monitoring
General
Limit cancer cells to degree that immune system can then eliminate without causing too much toxicity to the host - kill cells; prob not specifically rapidly growing cancer cells; affect all rapidly growing cells of body - numerous AE to numerous sys in body; kill enough cells that immune sys can finish up killing up rest
Goals of treatment
Pregnancy / lactation - killing rapidly growing cells: fetus rapidly trying to grow: complicates treatment if pregnant
Bone marrow suppression: antineoplastic sig suppression and decrease cell count; giving if already suppression problematic
Hepatic or renal impairment - toxic to all sys
CNS disorders
Caution
Variety routes: Oral, SQ, IM, IV, Topically, Intracavity, Intrathecal
Frequent and prolonged admin: Central vascular access devices are common: PICC line/port placed: easy access and last longer period of time; often caustic to veins to central access imp
Nurse require certification to administer chemotherapy - lot for safety
Routes
Monitor and intervene AE, hydration/nutritional/labs
Complicates growth and development if frequently hospitalized - high risk for infection: tricky to interact with kids appropriately: figure out good ways to assist fam so learn and play and explore appropriately for age and development
Needs support, comfort, to explore and learn like other children
Body image, lack of energy, parental need to protect child-isolate
Risk for infection diff; body image diff if lose hair; challenge for variety reasons
Children - Antineoplastics across the lifespan
Monitor and intervene AE, hydration/nutritional/labs/status
Body image (hair loss - some shave head); fear of diagnosis, treatment, job (not able work because too ill can be financial strain - very expensive so depending on insurance is financial strain; trying deal with diagnosis and other social things), financial strains, social issues
Need networking support systems, teaching, reassurance, and comfort
Adults - Antineoplastics across the lifespan
Monitor and intervene AE, hydration/nutrition/labs
More susceptible to the CNS, GI, renal, liver effects – may need reduced dose - toxicities of drugs - might need lower dose
Older adults - Antineoplastics across the lifespan
Diff classifications because affecting cancer in diff ways; target cell in diff ways
EX of antineoplastic drugs: classifications/prototypes
kills cancer cells
MoA: - Alkylating Agents: Prototype: Cyclophosphamide (Cytoxan)
antineoplastic; treats cancer
Indication: - Alkylating Agents: Prototype: Cyclophosphamide (Cytoxan)
toxic increase in uric acid level, CNS toxicity, hemorrhagic cystitis - bleeding in the urine - imp encourage adequate hydration to prevent it
AE: - Alkylating Agents: Prototype: Cyclophosphamide (Cytoxan)
Encourage hydration to prevent cystitis; see general
Nursing: - Alkylating Agents: Prototype: Cyclophosphamide (Cytoxan)
kills cancer cells; some autoimmune disease
MoA: - Antimetabolites: Prototype: Methotrexate (Rheumatrex)
antineoplastic; treats cancer
Indication: - Antimetabolites: Prototype: Methotrexate (Rheumatrex)
Gastrointestinal ulceration, bone marrow suppression

See general
Nursing: - Antimetabolites: Prototype: Methotrexate (Rheumatrex)
kills cancer cells
MoA: - Antitumor Antibiotics: Prototype: Doxorubicin (Adriamycin)
antineoplastic; treats cancer
Indication: - Antitumor Antibiotics: Prototype: Doxorubicin (Adriamycin)
injection site extravasation (vasocostic: monitor IV site closely - cause localized tissue necrosis if not careful); cardiotoxic (montior cardiac func closely)
AE: - Antitumor Antibiotics: Prototype: Doxorubicin (Adriamycin)
see general
Nursing: - Antitumor Antibiotics: Prototype: Doxorubicin (Adriamycin)
Affecting all rapidly growing cells
Alopecia – hair loss
CNS/PNS: neuropathy/cognitive dysfunction, headache, dizziness
CV/Pulmonary – risk toxicity
Myelosuppression – leukopenia, anemia, thrombocytopenia
GI: N/V, anorexia, diarrhea/constipation; mucous membrane deterioration (stomatitis)
Liver/renal – risk toxicity
Skin reactions: rashes; blisters; photosensitivity
GU/reproductive risks – cystitis; dysfunction
Gen antineoplastic AE
Assessment
Nursing Diagnosis
Outcomes: what achieve: The client will receive:
Nursing: antineoplastic assessment/diagnosis/outcome
H&P, Contraindications (pregnancy/ lactation, etc.), monitor labs: CBC (imp - weekly), renal/liver functions regular basis - see if decline - see if getting toxic; respiratory or cardiac disease (status of these)
Head to toe - note any AE happening for pat
Assessment - Nursing: antineoplastic assessment/diagnosis/outcome
Fatigue R/T drug effects (anemia) disease effects
Disturbed body image related to alopecia, skin effects …
Risk for injury
Risk for infection - HUGE; neutropenic
Nursing Diagnosis - Nursing: antineoplastic assessment/diagnosis/outcome
Best therapeutic effect - killing the cancer; cancer cells die and tumor shrink; hope to remission; take antineoplastic drugs, surgery, and radiation
Limited adverse effects - hard goal; most become pretty ill at some point because nature drugs; try intervene to lessen severity AE
Understanding or drug therapy, AE, comfort measures
Outcomes: what achieve: The client will receive: - Nursing: antineoplastic assessment/diagnosis/outcome
Do for all pats receiving antineoplastic drugs
Schedule blood tests to monitor bone marrow function, liver, renal
Monitor AE, pt. response
Adm. meds (anti-nausea, antidiarrheal, etc.)- intervene as appropriate to AE and meds to treat AE
Ensure hydration to decrease risk of renal toxicity - sometimes hydration can be hard
Provide small freq. meals instead larger (harder digest and provoke nausea), good mouth care imperative to prevent effects, dietary consult to maintain nutrition - visit with dietician on good path to maintain nutrition
Arrange for proper head covering for alopecia-temp. control; esp if really cold; hair does a lot insulation
Avoid exposure to infection - measures take to avoid infection; imp to avoid
Observe for signs of bleeding - suffer from thrombocytopenia; report so intervene
Energy conservation - suffer from fatigue from antineoplastics and/or cancer and/or anemia; discuss this
Barrier contraception - utilized for pats getting antineoplastic drugs and having sex protect partner from from agents, excreted in bodily fluids up to 48 hours; neeed best protect partner from agents; child-bearing age: cogniscent to prevent pregancy because hinders growth of fetus
Nursing: antineoplastic: gen implementation
Alopecia
Skin probs/effects
Nursing management: alopecia/skin
Begins 2 to 3 weeks after start of tx with antineoplastic drugs
Obtain wig/scarves/caps/hats
Avoid vigorous brushing hair
Shave head once hair loss begins and get covering
Re-growth begins 2 to 3 month after treatment ends; May be different thickness and texture than old hair
Alopecia - Nursing management: alopecia/skin
Diff types of rashes/blisters
Protective clothing
sun-burn easily - protection from sun; reduce impact to skin as best can
Skin probs/effects - Nursing management: alopecia/skin
Sig role in preventing nausea
Goal: prevent with very first treatment; then have anticipatory and feel it coming and more likely experience it again - want to stay ahead of it
Chemotherapy pattern of nausea
Prevention
Nursing management GI effects: treatment induced nausea
Early: first 12 hours
Delayed: 2 to 5 days
Anticipatory (goal: no nausea from first dose)
Chemotherapy pattern of nausea - Nursing management GI effects: treatment induced nausea
Bland diet before and after chemo (not spicy, heartburn, upset stomach, easily digestable); adequately hydrate before chemo - less likely experience dehydration after if vomit after
Pre-medication 30 min prior to chemo: ondansetron
Around the clock dosing of antiemetics for 48 hours after admin of antineoplastic
Prevention - Nursing management GI effects: treatment induced nausea
Causes (varies): N/V/D/constipation/fatigue/pain
Individualize plan to address all contributing factors - figure out exact cause - if cannot use gen measures to ensure getting nutrition needed
Nursing management GI effects: anorexia
Control N&V
Good oral care
Pain meds prior to eating
Conserve energy so not too tired to eat
Small, freq. meals high in calories and protein - real dense
Avoid noxious stimuli (odors/visual/conversations)
Nutritional Supplements-Ensure; high protein/calorie milkshakes
Treat constipation/diarrhea
Appetite stimulants - stimulate wanting to eat; more severe cases anorexia
Last resort- PEG tube/NG tube enteral feedings/TPN (ABSOLUTE LAST RESORT: not great source nutrition) - diff kinds feeding
Individualize plan to address all contributing factors - figure out exact cause - if cannot use gen measures to ensure getting nutrition needed
Stomatitis
Mucositis
Ulcers diff - painful; hard eat and drink; maintaining hydration imp; imp assess and find ulcers early on
Teach pt. to report early signs of dryness of mouth, tenderness of mouth/with eating, lesions
Pain medication needed!
Good oral hygiene - good thing do to prevent them
Maintain hydration
Mouth rinses – Magic mouthwash - not want alcohol mouthwashes; lidocaine in there, provider tells what to be included
No smoking/alcohol/spicy or acidic foods - avoid irritation: burn and pain
Liquid supplements for nutrition - best intake to deal with mouth sores so can heal
Nursing management: GI effects: stomatitis/mucositis
Ulceration of oral mucous membranes
Stomatitis - Nursing management: GI effects: stomatitis/mucositis
