Cancer invading the bone marrow can cause which affects?
- Decreased RBCs
- pathologic fractures
- thrombocytopenia
Which type of cancer puts patients at greatest risk for infection?
Leukemia
Which statement about gastrointestinal functioning cancer are true?
- Tumors may increase the metabolic rate
2. the liver is a common sight of cancer metastasis
Which common hematologic conditions result from cancer made in the bone marrow?
Anemia and thrombocytopenia
A patient asked the nurse why untreated cancers cause gastrointestinal problems. Which responses are appropriate?
- A tumor in the bow can decrease your ability to absorb necessary nutrients
- it stops absorption of necessary fat and protein enzymes
- tumors my increased metabolic needs what you are unable to meet
Which factors determine the type of therapy for cancer
- Type and location of cancer
- overall health of patient
- whether the cancer has metastasized
- family history and genetics
Which examples illustrate appropriate prophylactic cancer surgery?
- Excision of lesion’s shown on biopsy to be precancerous
2. Removal of tissue which may predispose cancer development due to family history
What is the purpose of cytoreductive surgery for cancer?
Cancer control by reducing the size of the tumor
Palliative surgery may be performed for which reason reason?
Relieving pain and relieving in obstruction
For what purposes make cancer survivors need reconstructive surgery?
- Breast reconstruction
- Revision of scars and release of contractures
- Bowel reconstruction
What is the meaning of the inverse square law for radiation exposure?
The further away a person is from a radiation source the last radiation is absorbed
Which factors are used to terminal cancer patients absorbs radiation dose?
- Intensity of radiation exposure
- proximity of radiation source of cells
- duration of exposure
Which statement about stereotactic body radiotherapy are true?
- The greater number of normal cells are spared
- three-dimensional to my imaging is used
- Hi radiation doses maybe use
Was a therapeutic dose of radiation fractionated for cancer treatment?
to ensure a higher cancer cell kill with less damage than normal cells
At what point is a patient radioactive when receiving radiation treatment by telly therapy and therefore a potential danger to other people?
The patient is never radioactive
What are the side effects of radiation
