B, C, E
A patient who is undergoing cancer chemotherapy asks the nurse why she is taking three different chemotherapy drugs. What is the nurse's best response? A. "Your cancer was very advanced and therefore requires more medications." B. "Each drug attacks the cancer cells in a different way, increasing the effectiveness of the therapy." C. "Several drugs are prescribed to find the right drug for your cancer." D. "One drug will cancel out the side effects of the other."
B. "Each drug attacks the cancer cells in a different way, increasing the effectiveness of the therapy. "Effectiveness of chemotherapy is increased by use of multiple drugs from different classes that attack cancer cells at different points in the cell cycle. Thus, lower doses of each individual agent can be used to reduce side effects. A third benefit of combination chemotherapy is reduced incidence of drug resistance. Options 1, 3, and 4 are incorrect. A combination of drugs is given for most cancers regardless of how advanced the cancer is. The multi-drug is not given to find the right drug because many may exert therapeutic effects. The drugs do not "cancel out" each other but work together.
The nurse notes that the patient has reached his nadir. What does this finding signify? A. The patient is receiving the highest dose possible of the chemotherapy. B. The patient is experiencing bone marrow suppression and his blood counts are at their lowest point. C. The patient has peaked on his chemotherapy level and should be going home in a few days. D. The patient is experiencing extreme depression and will be having a psychiatric consult.
B. The patient is experiencing bone marrow suppression and his blood counts are at their lowest point. The nadir is the point of greatest bone marrow suppression, as measured by the lowest neutrophil count. Options 1, 3, and 4 are incorrect. The nadir does not refer to chemotherapy dose, level, or client symptoms.
What is the most effective treatment method for the nausea and vomiting that accompanies many forms of chemotherapy? A. Administer an oral antiemetic when the patient complains of nausea and vomiting. B. Administer an antiemetic by intramuscular injection when the patient complains of nausea and vomiting. C. Administer an antiemetic prior to the antineoplastic medication. D. Encourage additional fluids prior to administering the antineoplastic medication.
C. Administer an antiemetic prior to the antineoplastic medication. For maximum effect, patients should be given an antiemetic prior to the start of treatment. Options 1, 2, and 4 are incorrect. Waiting to give an antiemetic until after the chemotherapy has started may result in a delay in treatment of the nausea and vomiting. IM injections are usually avoided during chemotherapy because of an increased risk of infection. Fluids are encouraged throughout chemotherapy but will not prevent or treat the nausea and vomiting that may occur.
Nursing care of patients undergoing chemotherapy
Collaborative with MD and pharmacist Educate pt and family - drug therapy - SE to report (chills, fever, mouth sores, n/v, D, neuropathy)... report even with no fever - adequate nutrition for n/v or healing of tissues - plan of care to prevent and control s/s - follow-up for labs
A nurse is preparing to administer leucovorin to a client who has cancer and is receiving chemotherapy with methotrexate. Which of the following responses should the nurse use when the client asks why leucovorin is being given? a. "Leucovorin reduces the risk of a transfusion reaction from methotrexate." b. "Leucovorin increases platelet production and prevents bleeding." c. "Leucovorin potentiates the cytotoxic effects of methotrexate." d. "Leucovorin protects healthy cells from methotrexate's toxic effect."
D
Which of the following statements by a patient who is undergoing antineoplastic therapy would be of concern to the nurse? (Select all that apply.) A. "I have attended a meeting of a cancer support group." B. "My husband and I are planning a short trip next week." C. "I am eating six small meals plus two protein shakes a day." D. "I am taking my 15-month-old granddaughter to the pediatrician next week for her baby shots." E. "I am going to go shopping at the mall next week."
D. "I am taking my 15-month-old granddaughter to the pediatrician next week for her baby shots." E. "I am going to go shopping at the mall next week." Patients and family members should avoid receiving live virus vaccinations or exposure to chickenpox. The patient could have an exacerbation or a more pronounced episode of the disease. The patient should not care for the granddaughter if vaccination with live viruses is planned. The patient should also avoid crowds, especially in enclosed spaces when possible, to minimize exposure risk. The nurse should discuss measures to minimize the risk of infections if the patient desires to go shopping. Options 1, 2, and 3 are incorrect. Attending a support group, maintaining normal activities when possible, and eating small, frequent meals with sufficient protein are routine care measures during chemotherapy.
TARGETED THERAPIES: PROTEIN KINASE INHIBITORS
Don't memorize IMATINIB (GLEEVEC) - A TYROSINE-KINASE INHIBITOR USED IN THE TREATMENT OF MULTIPLE CANCERS, MOST NOTABABLY CHRONIC MYELOGENOUS LEUKEMIA (CML). - KILLS CANCER CELLS BY TURNING OFF TYROSINE KINASES. IN ORDER TO SURVIVE, CELLS NEED SIGNALING THROUGH PROTEINS (SIGNAL CASCADE) TO KEEP THEM ALIVE. - BECAUSE TYROSINE KINASE ENZYME EXISTS ONLY IN CANCER CELLS AND NOT IN HEALTHY CELLS, IMATINIB WORKS AS A TARGETED THERAPY—ONLY CANCER CELLS ARE KILLED THROUGH THE DRUG'S ACTION - THE 5 YEAR SURVIVAL RATE WITH CML INCREASED FROM 31% IN 1993 (BEFORE GLEEVEC'S 2001 FDA APPROVAL) TO 59% IN 2009 - FEW SIDE EFFECTS - AVERAGE = $120,000 A YEAR IN 2016
TARGETED THERAPY: MONOCLONAL ANTIBODIES (MAB)
ENGINEERED TO ATTACK ONLY 1 SPECIFIC TYPE OF TUMOR CELL; ONCE MAB BINDS TO ITS TARGET CELL, THE CANCER CELL DIES, OR IS MARKED FOR DESTRUCTION • RITUXIMAB (RITUXAN) - SES: ANAPHYLAXIS, PRURITUS • BEVACIZUMAB (AVASTIN) - BLOCKS ANGIOGENESIS BY INHIBITING VASCULAR ENDOTHELIAL GROWTH FACTOR A (VEGF-A) - USED FOR METASTATIC COLORECTAL, NSCLC, OVARIAN CANCER - SES: LIFE-THREATENING: HEMORRHAGE, GI PERFORATION & WOUND DEHISCENCE, ARTERIAL CLOTS, HYPERTENSIVE
Neutropenia: absolute neutrophil count
Identify the risk for infection by looking at WBC indices and calculation the absolute neutrophil count (ANC) ANC: WBCxneutrophils +bands ANC of <1000= high risk ANC of <500= very high risk for infection -can get an infection from themselves
Treatment of neutropenia
In addition to neutropenic precautions: Medication- biological response modifiers -to stimulate neutrophil production -prototype: filgrastim (Neupogen) SC SE: fever, alopecia, N/V/D, bone pain, HA, rash - discontinue when ANC is increased 10,000.. want is to be 2,000-3,000
Genomics
Match a cancer to the gene and then match a gene to the med.. everyones cancer is different ex. lung cancer is Dif for everyone
Problems and risks with neutropenia
NEUTROPENIC INFECTION IS A PROBLEM!!! • OCCUR IN 50% - 80% OF PATIENTS WITH CANCER • RESULT IN HOSPITALIZATION FOR 60,000 PATIENTS ANNUALLY • 1 IN 14 PATIENTS WILL DIE OF SEPTIC SHOCK IDENTIFY YOUR PATIENT'S RISK FOR INFECTION RISK FACTORS: • AGE >65 YEARS • WOMAN > MEN • LOW BODY MASS INDEX • PRESENCE OF COMORBIDITIES • LABORATORY ABNORMALITIES • POOR NUTRITIONAL STATUS • OPEN WOUND, OR RECENT SURGERY • ADVANCED DISEASE STAGE • BONE MARROW INVOLVEMENT • TYPE OF CANCER (IE, HEMATOLOGIC, LUNG, BREAST, COLORECTAL, OR OVARIAN) • GENOTYPE
Alopecia
Primary prevention: cold cap (makes head cold during chemo bc it causes vasoconstriction and the chemo is running through blood) could chew ice also to prevent mouth sores Secondary Interventions: -avoid washing hair every day -avoid use of hairdryers -cut long hair/shave early -wig (choose early) -head covering Hair is rapidly dividing cells and chemo kills cells
Bone marrow suppression: thrombocytopenia (PLTS < 150,000)
Safety: nurses should institute bleeding precaution - For platelets <50,000 Avoid trauma -touch pt gently, use lift sheet when repo -avoid IM injections and venipunctures ... if necessary, use smallest gauge needle.... apply firm pressure to site for 5-110 minutes -no sharp edge razors- use electric razors -no rectal tamps -no enemas Assess for s/s of bleeding -test all urine and stool for blood -observe IV sites for bleeding Petechiae can occur with thrombocytopenia
Rapid recap
SIDE EFFECTS OF CHEMOTHERAPY (AND RADIATION WHEN TARGETS BONE MARROW) • DOSE DEPENDENT • BONE MARROW SUPPRESSION • 1) DECREASED WBC (NEUTROPENIA OR LEUKOPENIA) • 2) DECREASED ERYTHROCYTES (ANEMIA) • 3) DECREASED PLATELETS (THROMBOCYTOPENIA) NADIR - TIME WHEN BONE MARROW ACTIVITY

How is chemotherapy given?
SYSTEMIC CHEMOTHERAPY: IV OR PO. ENTER BLOODSTREAM AND REACH ALL AREAS OF BODY - USED FOR CANCERS THAT HAVE SPREAD (METASTASIZED) REGIONAL CHEMOTHERAPY: INJECTED DIRECTLY INTO/CLOSE TO TUMOR. • INTRAVESICULAR - BLADDER • INTRAVENTRICULAR - BRAIN • INTRAPERITONEAL - OVARIAN CANCER • CONCENTRATES THE DOSE OF CHEMO REACHING THE CANCER CELLS. REDUCES SIDE EFFECTS BY LIMITING THE AMOUNT OF DRUG REACHING THE REST BODY. IN CYCLES - TREATMENT FOLLOWED BY A REST PERIOD TO GIVE THE BODY TIME TO RECOVER. GENERALLY LAST ABOUT 2 TO 4 WEEKS, USUALLY GET AT LEAST SEVERAL CYCLES
Antiemetics
Serotonin antagonists - odansetron (zofran) -BBW for prolonged QT interval Phenothiazides - prochlorperazine (compazine) ... antipsychotic for nausea Benzodiazepines - lorazepam (Ativan) Metochlopromide (reglan) Steroids - decadron
Targeted therapies
TARGETS SPECIFIC GENES OR PROTEINS TO STOP CANCER GROWTH - CAN BLOCK OR TURN OFF THE SIGNALS THAT ARE ALLOWING CANCER CELLS TO DIVIDE - FOUND IN OR ON CANCER CELLS, OR IN CELLS RELATED TO CANCER GROWTH LIKE BLOOD VESSELS • OFTEN USED WITHWITH CHEMO • TWO MAIN TYPES: MONOCLONAL ANTIBODIES OR SMALL MOLECULE DRUGS • DO NOT WORK FOR EVERYONE! - NEED TO TEST THE PATIENT FOR TYPES OF PROTEINS, MUTATIONS OF THE CANCER • RESPONSE TO THESE MEDS CAN BE TEMPORARY - CANCER CELLS CAN MUTATE - CANCER CELLS FIND A NEW PATHWAY TO GROW • SIDE EFFECTS DIFFERENT FROM CHEMO: SKIN, HAIR, EYE PROBLEMS
CAR-T THERAPY (CHIMERIC ANTIGEN RECEPTOR T-CELL THERAPY)
Take blood out, take abcs, use a virus and inject a new antibody to new T cells, making medicine for each person... grow new T cells and then infuse it back into the body and divide with the anticancer so the T cells swarm the tumor and kill is... indication is for blood cancers.. one time infusion cure even if cancer s=comes back the T cells are still there • INDIVIDUALIZED TREATMENT FOR SOME BLOOD CANCERS, 50-60% CURECURE • TAKE SAMPLE OF PT'S BLOOD, MODIFY THOSE T-CELLS IN LAB WITH VIRUSES, GIVE CHEMO TO LOWER IMMUNE SYSTEM, 3 WEEKS LATER INFUSE GENETICALLY MODIFIED T-CELLS BACK TO PT. • SIDE EFFECTS: - CYTOKINE RELEASE SYNDROME COMMON IN 80% OF PTS (FEVER, LOWER BLOOD PRESSURE, AND SHORTNESS OF BREATH). FREQUENT VS, APPLY O2 - NEUROTOXICITY COMMON (FORGETFULNESS, VIOLENT SEIZURES) FREQUENT NEURO ASSESSMENTS, HAVE PT WRITE A SENTENCE. USUALLY REVERSIBLE WITH STEROIDS.
