chemo and radiation and pain Flashcards
chemo
Cytotoxic medications that damage a cell’s DNA or destroy rapidly dividing cells.
adverse effects of chemo- related to
related to the unintentional harm done to normal rapidly proliferating cells, such as those found in the mucous membranes of the gastrointestinal (GI) tract, hair follicles, and bone marrow.
Agents that protect healthy cells (cytoprotectants or chemoprotectants) are given before or with chemotherapy to decrease the effect on normal tissues are:
amifostine and mesna
zofran
gut proflaxis
special mouthwash
preparing chemo
- Most chemotherapy medications, including oral, are absorbed through the skin and mucous membranes.
- Anyone preparing, giving or disposing of these medications must wear proper personal protective equipment.
- cytotoxic: can cause birth defects, special gloves, urine and stool disposed in chemo bin
routes of chemo
- Topical
- Oral: Oral medications should not be crushed, split, broken or chewed.
- IV
- Intra abdominal, intrathecal (spine), intrapleural (pleural space),
Intra ventricular, intra bladder
lines for chemo
- A central catheter is usually placed for chemotherapy or laboratory blood testing.
- Chemo can cause serious damage to the skin and muscle tissue if it infiltrates.
- Two of the more commonly used included PICC lines and implanted port.
- The implanted port is used when therapy is intended to be given on a long-term basis.
- needs blood checked constantly
- more people die from sepsis than cancer
complication: Immunosuppression/neutropenia due to
- Due to bone marrow suppression by cytotoxic medications
- The most significant adverse effect of chemotherapy
- serious
Immunosuppression/neutropenia nursing considerations body wise
- Monitor temperature, white blood cell (WBC) count, and absolute neutrophil count (ANC).
- A fever greater than 37.8° C (100° F) should be reported to the provider immediately.
Neutropenia nursing actions
- Monitor skin and mucous membranes for infection (breakdown, fissures, and abscess).
- Cultures should be obtained prior to initiating antimicrobial therapy.
- The risk of serious infection increases as the ANC falls.
- The nurse should implement neutropenic precautions, including placing the client in a private room.
An ANC less than 1,000/mm3 indicates a
weak immune system
Neutropenic Precautions
- Protect the client from possible sources of infection (plants, change water in equipment daily).
- Have client, staff, and visitors perform frequent hand hygiene. Restrict visitors who are ill.
- Avoid invasive procedures that could cause a break in tissue (rectal temperatures, injections, indwelling urinary catheters) unless necessary.
- Keep dedicated equipment (blood pressure machine, thermometer, stethoscope) in the client’s room.
- negative airflow
- toothbrush in dishwasher
Client Education for neutropenic
- Encourage the client to avoid crowds while undergoing chemotherapy.
- Take temperature daily. Report fever greater than 37.8° C (100° F) or other manifestations of bacterial or viral infections immediately to the provider.
- Avoid food sources that could contain bacteria (fresh fruits and vegetables; undercooked meat, fish, and eggs; pepper and paprika).
- Wash all dishes in hot, soapy water or a dishwasher. Wash glasses and cups after each use.
- Wash toothbrush daily in the dishwasher or rinse in a bleach solution.
complications: anemia
- Monitor for fatigue, pallor, dizziness, and shortness of breath.
- Help the client manage anemia-related fatigue
- Administer darbepoetin alfa, epoetin, and ferrous sulfate as prescribed.
- Monitor Hgb values to determine response to medications. Be prepared to administer blood if prescribed.
complication: Thrombocytopenia
Monitor for petechiae, ecchymosis, bleeding of the gums, nosebleeds, and occult or frank blood in stools, urine, or vomitus.
thrombocytopenia Institute bleeding precautions.
- Avoid IVs and injections.
- Apply pressure for approximately 10 min after blood is obtained.
- Monitor platelet count, and be prepared to administer platelets if the count falls below 10,000/mm3.
thrombocytopenia client education
- Instruct the client and family how to manage active bleeding.
- Instruct the client to use electric razor and soft-bristled toothbrush, avoid blowing nose vigorously, ensure that dentures fit appropriately.
- Avoid the use of NSAIDs.
- Wear closed-toes shoes
- Remove tripping hazards in the home
complication: nausea, vomiting, anorexia meds
- Serotonin blockers, such as ondansetron, have been found to be effective and are often administered with corticosteroids, phenothiazines, and antihistamines. (always give before)
- Corticosteroids (dexamethasone, methylprednisolone) helps with inflammation
- Histamine blockers and proton pump inhibitors (omeprazole, ranitidine)
- Metoclopramide
- Lorazepam: keeps them calm
- Cannabinoids (dronabinol, nabilone): helps with eating
***All used for chemotherapy-induced nausea and vomiting, and should be given BEFORE treatment
side effects from zofran
- diarrhea
- headache: most common
- fever
- lightheadedness: not enough hemoglobin
- weakness
- constipation
- rash
- blurred vision
- muscle spasm
nausea and food
- Encourage the client to eat several small meals a day if better tolerated.
- Suggest that the client select foods that are served cold and do not require cooking. Cooking food can emit odors that stimulate nausea. cold foods and bland
- Encourage consumption of high-protein, high-calorie, nutrient-dense foods and avoidance of low- or empty-calorie foods. (continuous feeds, tpn, g/jtube)
complications: alopecia
- Discuss the effect of alopecia on self-image.
- Discuss options such as hats, turbans, and wigs to deal with hair loss.
- Inform clients that hair loss occurs 7 to 10 days after treatment begins (for some agents). Encourage the client to select hairpiece before treatment starts.
- Reinforce that alopecia is temporary, and hair should return about 1 month after chemotherapy is discontinued.
- The new hair can differ from the original hair in color, texture, and thickness.
complications: Mucositis and Stomatitis nursing actions
- inflammation, swelling, soares
- Examine the client’s mouth several times a day, and inquire about the presence of oral lesions.
- Avoid using glycerin-based mouthwashes or mouth swabs.
- Nonalcoholic, anesthetic mouthwashes are recommended.
- Administer a topical anesthetic prior to meals.
Discourage consumption of salty, acidic, or spicy foods. - Offer oral hygiene before and after each meal.
- ensure and boost: increase proteins
complications: Chemotherapy‑induced peripheral neuropathy nursing actions
- Loss of sensory or motor function of peripheral nerves
- Monitor in hands and feet, loss of taste, and constipation.
- Monitor for orthostatic hypotension.
- Teach the client how to prevent injury, including falls, and that loss of sensation makes the client unaware of heat, cold, or pressure.
- Inform regarding risk of erectile dysfunction and treatment options.
radiation
- One of the oldest nonsurgical methods of cancer treatment
- 50% of all cancer patients will receive radiation therapy at some point in their treatment
- Cells damaged by radiation either die or become unable to divide.
- Gamma rays are used most commonly because of their ability to penetrate tissues and damage cells.
radiation: teletherapy
distance treatment, the radiation source is external to the patient.
