| Question | Answer |
|---|---|
| Plant Alkaloids: Specific Drugs | Vinca alkaloids Taxanes Podophyllotoxins |
| Vinca alkaloids Specific Drugs | Interfere with amino acid production in S phase and formation of microtubules in M phase |
| Taxanes Specific Drugs | Interfere in M-phase with microtubules |
| Podophyllotoxins Specific Drugs | Cells are unable to divide since cells are stopped during S and G2 phases by the podophyllotoxins |
| Antimetabolites: Specific Drugs | Interfere with synthesis of RNA and DNA, make it impossible for cancerous cell to divide into two daughter cells |
| Drugs are used to treat: Specific Drugs | Leukemia, lymphoma, solid tumors, autoimmune diseases |
| Alkylating agents: Nonspecific Drugs | Change cell to more alkaline environment, which in turn damages the cell |
| Antineoplastic antibiotics: Nonspecific Drugs | Interfere with DNA and RNA synthesis, delaying or inhibiting cell division |
| Miscellaneous antineoplastic arugs: Nonspecific Drugs | Number of drugs are used for antineoplastic actions, do not belong to any one category |
| Nonspecific Drugs Adverse Reactions | Nausea and vomiting from highly emetic drugs or potential of IV extravasation of irritating solutions |
| Adverse reactions common to antineoplastic drugs: | Bone marrow suppression; Stomatitis; Diarrhea; Hair loss Leukopenia and thrombocytopenia may cause cycles of chemotherapy to be delayed until blood cell counts can be raised Damage gonads causing fertility problems |
| Contraindications: Antineoplastic drugs Nonspecific Drugs | Leukopenia; Thrombocytopenia; Anemia; Serious infections; Renal disease; Hypersensitivity to drug; During pregnancy or lactation |
| Precautions: Antineoplastic drugs Nonspecific Drugs | Renal or hepatic impairment; Active infection; Debilitating illnesses; Those who have completed treatment with other antineoplastic drugs or radiation therapy |
| Nursing Process: Assessment Preadministration assessment: | Type & location of the neoplastic lesion Stage of the disease. Pt’s general physical & emotional condition. Anxiety or fears the pt may have regarding chemotherapy. Previous, concurrent treatments. Current nonmalignant disease or disorder. The patient’s |
| Nursing Process: Assessment Ongoing assessment: | The patient’s general condition The patient’s individual response to the drug Adverse reactions that may occur Guidelines established by the primary health care provider or hospital Results of periodic laboratory tests and radiographic scans |
| Nursing Process: Nursing Diagnoses | Imbalanced nutrition: Less than body requirements Fatigue Risk for injury Risk for infection Disturbed body image Anxiety Impaired tissue integrity |
| Nursing Process: Planning Expected outcomes: | An optimal response to therapy Support of patient needs related to the management of adverse reactions Understanding of prescribed treatment modalities |
| Nursing Process: Implementation Promoting an optimal response to therapy: Guidelines established by the setting for care: | Increase vital signs, if patient’s condition changes Consult references to obtain information regarding preparation and administration of drug, average dose ranges, all adverse reactions, warnings and precautions given by manufacturer |
| Nursing Process: Implementation Promoting an optimal response to therapy: Protection of the Provider | The Occupational Safety and Health Administration (OSHA) guidelines Nurses need to be protected during administration and cleanup from accidental ingestion, inhalation, or absorption of drugs |
| Nursing Process: Implementation Promoting an optimal response to therapy: Oral Administration | Administer antineoplastic drugs orally GI tract functions normally when oral drugs are well absorbed |
| Nursing Process: Implementation Promoting an optimal response to therapy: Parenteral Administration | Give injection into large muscles using Z-track method Sites should be rotated, charted appropriately if the injections are given frequently |
| Nursing Process: Implementation Monitoring and Managing patient needs Imbalanced Nutrition: Less than body requirements | nutritional status of patient before and during treatment small, frequent meals to stimulate appetite eat healthy meals high in(protein) body weight weekly Provide soft or liquid food report white patches on tongue, throat, gums; Burning sensation; |
| Nursing Process: Implementation Monitoring and managing patient needs Fatigue, infection and injury: Myelosuppression | Help patient learn to prioritize activity to conserve energy Monitor patients with thrombocytopenia for bleeding tendencies Apply pressure to injection site for 3 to 5 minutes to prevent bleeding into tissue and formation of hematoma avoid use of ele |
| Nursing Process: Implementation Monitoring and managing patient needs Disturbed body image | Inform patient that hair loss may occur if hair loss is associated with antineoplastic drug being given Forewarn patient that hair loss may occur suddenly and in large amounts Assist in making plans for purchase of wig or cap to disguise hair loss until |
| Nursing Process: Implementation Monitoring and managing patient needs Anxiety | Offer empathetic, emotional support to patient, and family members |
| Nursing Process: Implementation Monitoring and managing patient needs Impaired tissue integrity | Instruct patient about adverse reaction as it can be both surprising and painful Ensure that extravasation protocol orders are signed and extravasation kit is on unit before vesicant drugs are administered Monitor IV site continuously and check for |
| Nursing Process: Implementation Educating the patient and family: | Take drug only as directed and do not alter the dose unless advised All recommendations given by the primary health care provider are important Effectiveness or action of the drug could be altered if these directions are ignored Keep all appointments |
| Nursing Process: Evaluation | The therapeutic effect is achieved Adverse reactions are identified, reported and managed Anxiety is reduced |
