38
what is bone marrow aspiration? what is a con to this procedure?
- procedure that takes a sample of your bone marrow for examination
- very painful
39
which diagnostic test is the most definitive means of diagnosing cancer?
- biopsy --> piece of tissue is surgically removed for histological examination
40
what are the 3 different types of a biopsy?
1. needle
2. incisional (only a sample of the lesion is removed)
3. excisional (entire lesion removed)
41
why is grading and staging of a cancer so important?

43
what are 6 different types of treatment for cancer
- surgery

- radiation
- hormonal therapy
- targeted therapy
- hematopoietic drugs
44
what is combination therapy?
- treatment whereas the patient is taking two or more drugs
45
why do we use combination therapy for cancer?
- so the drugs hit different parts of the cell cycle
- avoid resistance
- protect normal cells & allow them time to repair
46
what is the difference between radiation & chemo?
- radiation = more localized & targeted, damage to cells is permanent (ex. hair wont grow back)
- chemo = more systemic, hair recovers
47
does damage to other cells still occur with radiaition?
- yes, radiation will damage cells around the tumour
48
what type of cancer do you want to use chemo vs radiation for?
- solid cancer = radiation
| - dissemiated cancer = chemo
49
describe pain in relation to cancer treatment

50
what is a significant barrier to effective pain management?
- inadequate pain assessment
51
describe pain assessment related to cancer treatment
- vital signs & patient behavior do not provide enough data

63
which are killed from first to last order: RBC, WBC, platelets? how does this effect which conditions are most common regarding hematological effects of chemo?
- WBC then platelets then RBC
| = neutropenia, then thrombocytopenia, then anemia
64

- the lowest WBC we are willing to accept while giving chemo
- usually 7-14 days to reach nadir
65
describe the assessment for hematological conditions when giving chemo
- frequent lab work (CBC, WBC, Hgb, platelets)
- look for signs of infection
- signs of bleeding
- vitals
66
what specific vitals should we consider when assesing hematological system

69
describe alopecia during chemo vs radiation
- chemo = systemic
| - radiation = only in treatment area
70
what is extravasation? is this a problem with chemo?
- when the IV is no longer going into the vein & leaking onto the tissue around
- very very bad with chemo
71
what do you do if someone who is receieving chemo complaing of pain in their hand
- stop the IV!!!
72
what is desquamation? what are the 2 types that occur with radiation
