ONS Tx Managment Flashcards
What side effect does amifostine (Ethyol) help to prevent for patients undergoing radiation therapy?
Salivary gland damage. It is a type of radio protector.
What are the most common acute side effects of radiation therapy?
Fatigue, skin irritation, bone marrow suppression, urinary or bowel dysfunction. And sit specific problems.
What population is at highest risk for secondary cancers?
Children and adolescent diagnosed with cancer 
In radiation Saftey. What does ALRA stand for?
As low as reasonably achievable.
What are the 3 main factors included in ALARA?
1.) time of exposure.
- minimize
2.) distance between you and the radiation source.
-double the distance between you and the RT source. doing this reduces RT exposure by x4
3.) Using radiation shields
- Use absorber materials, such as plexiglass for beta particles. And lead for x-rays and gamma rays
Melphalan (EVOMELA) chemotherapy has what sE that requires what special nursing intervention?
Mucositis, and placing ice in the patients mouth before, enduring infusion 
During the process of stem cell therapy transplant, this is the point at which new blood cells start to grow after chemotherapy. This is called.
Engraftment
During the process of stem cell therapy transplant, this is the point at which chemotherapy is given to prep your body for the transplant. This step is called
Conditioning
How are donors matched for stem cell transplants? What factor is looked at primarily?
HLA (human leukocyte Antigens)
What is the primary treatment for graft versus host disease?
Steroids and or immuno suppressant drugs
How long does it take to infuse stem cells?
Approximately 1 to 5 hours
How long does it take for your immune system to fully recover from a stem cell transplant? Is this the same for both autologous and allogenic?
Several months for autologous. One to two years for allogenic.
What chromosome is genetic information for HLA stored on?
Chromosome 6
What are the advantages and disadvantages to bone marrow as a vehicle for stem cell collection?
advantage: less graph versus host disease
Disadvantage: surgery required, and longer process for engraftment
What are the advantages and disadvantages to peripheral blood as a vehicle for stem cell collection?
Advantage: shorter time for cell engraftment
Disadvantage: higher risk versus host disease
What are the advantages and disadvantages to umbilical cord as a vehicle for stem cell collection?
Advantage: high in stem cells and low risk for graft versus host disease
Disadvantage: duration of my suppression and time required for engraftment
Myeloablative regimen
Is the administration of lethal doses of therapy to severely immuno, suppress and eradicate cancer cells only used for very healthy patients
Non-myeloablative Regimen
A reduced dose of chemotherapy and comparison to a myeloablative regimen. Used for older patients or those with comorbid conditions the goal is to suppress the immune system and enhance engraftment of stem cells
What are some side effects specific to stem cell infusions?
1.) pink or red tinged urine from the breakdown of cells, generally resolving within one to two days.
2.) garlic, smell or taste in the mouth as a result of breakdown of DMSO.
3.) Nausea, vomiting diarrhea.
4.) standard infusion reaction s/s
What blood cell counts does the clinical team look for to define engraftment?
ANC greater than 500 and platelet count greater than 20,000
Define chimerism
A term meaning successful in graft for patients who have received allogenetic transplants. Only donor cells remain.
 how is graft versus host disease diagnosed
Biopsy of the affected organ
What are risk factors for the development of graft versus host disease?
Older patients, peripheral stem cell collection, and having unrelated donors
What defines acute versus chronic graft versus host disease?
Acute occurs during the first 100 days post transplant, chronic is anything there after
