Neoplasms #1 (1) Flashcards
Benign Tumor
Cells grow only locally and cannot spread by invasion or metastasis
Malignant Tumor
Cells invade neighboring tissues, enter blood vessels, and metastasize to different sites
Neoplasm
An abnormal growth of tissue, benign or malignant, that serves no physiologic function. AKA tumor
Ondanestron (Zofran)
Use: Treatment and prevention of nausea and vomiting. Often used for postoperative nausea and for nausea related to chemotherapy or radiation therapy.
**Action: **Blocks the effects of serotonin at 5-HT3 receptor sites located in vagal nerve terminals and the chemoreceptor trigger zone in the CNS.
Side/Adverse Effects: headache, dizziness, drowsiness, constipation, diarrehea, abdominal pain, dry mouth, extrapyramidal reactions (involuntary movement of eyes, face, limbs)
**Nursing Implications: **
- Administer prior to emetrogenic event when possible (chemo, radiation, anesthesia induction)
- Assess daily bowel activity and stool consistency
- Teach patient to notify health care provider is extrapyramidal symptoms occur
- SAfety precautions for dizziness and drowsiness
Fatigue
- Most frequently experienced symptom of cancer and cancer treatment, regardless of the treatment protocol being utilized
- Universal symptom affects 70-100% of cancer patients
- Alters functional and cognitive status, sense of well-being, and relationships
- Receives little attention and priority from the health care team. Consider this nursing diagnosis when you assess you patient
Fatigue r/t increased waste production of cell destruction
Definition: An overwhelming, sustained sense of exhaustion and decreased capacity for physical and mental work at the usual level that is not relieved by rest.
Assessment Findings:
- inability to restore energy even after sleep
- lack of energy
- increase in rest requirements
- tired
- inability to maintain usual routines
- increase in physical complaints
- drowsy
- compromised concentration
Outcomes:
- Verbalizes increased energy and improved well-being
- Describes factors that cause or increase fatigue
- Describes factors that conserve energy
Nursing Interventions:
- Provide information about fatiguee
- Assess fatigue using 0-10 scale, ability to perform ADLs, mood and concentration abilities
- Allow patient time to express feelings, concerns about fatigue
- Help patient establish small, easily achievable short-term goals
- Help patient identify essential and nonessential tasks, prioritize as needed and determine what can be delegated. schedule priority activities at times of peak energy
- Teach strategies for energy conservation
- Assist to follow health lifestyle- adequate nutrition and rest, appropriate exercise
- Give patient permission to limit social and role demands
- Manage pain, N/V, other symptoms
Chemotherapy
The use of medications or chemical agents to destroy or interfere with the replicaiton of cancer cells. Normal and malignant cells are affected. Systemic treatment: travels through the bloodstream to affect cancer cells.
What cells in the body divide rapidly?
hair follicles, mucous membranes, GI mucosa, and bone marrow
What cells are the most severly affected by chemotherapy?
Normal cells that rapidly divide. the basis for many of the side effects experienced.
What is the goal of chemotherapy?
to destory cancer cells while doing minimal damage to normal cells and to cure the individual. If cure is impossible, control or palliation become the goal.
Neoadjuvant
may be given prior to primary treatment to shrink the tumor
Chemotherapy use
may be used as a primary treatment, an adjuvant modality (combined with surgery, radiation, biologic-therapy) or a pallative therapy
Combination Chemotherapy Protocols
Using two or more chemotherapies together
- Kills more cancer cells (improved tumor response)
- Reduces likelihood that cancer cells will become resistant
- Different mechanisms of action and different toxicities limit the severity of side effects
Preparation of chemotherapy
Class II biological safety cabinet or laminar airflow hood for all preparation by pharmacist or trained RN
Administration of Chemotherapy
- Double glove with disposable, non-powdered, thick latex gloves (or gloves manufactured as chemo resistant)
- Long sleeve disposable gowns with elastic/knitted cuffs
- Absorbent, plastic backed liner under work surface
- Disposable-puncture proof, shatter proof, leak proof plastic container for waste
- Leur-Lok fittings for syringes, tubings
- Double bag contaminated linen
- keep “spill kit” available (biohazard)
