Q

Why is the TNM staging system not used in small-cell lung cancer?

how does a PET scan reveal lung cancer
measures metabolic activity in tissue. (Malignant tissue is more metabolicly active than normal tissue so it shows up readily

50%
39
when is radiation used as a primary therapy
in a patient who is unable to tolerate surgical resection due to comorbidities

45
what is the primary treatment for SCLC
chemotherapy (usually a combination of two or more drugs)
46
which chemotherapy drugs are frequently used to treat lung cancer
vepesid, paraplatin, platinol, taxol, navelbine, cytoxin, efex, taxotere, gemzar, alimta
47
what is "biologic and targeted" therapy
the use of drugs the block the growth of molecules involved in specific aspects of tumor growth (less toxic than chemotherapy)
48
MOA of tarceva (biologic and targeted therapy)
treatment of NSCLC by blocking growth stimulating signal
49
MOA of avastein (biologic and targeted therapy)
inhibits angiogenisis thereby preventing the growth of cancer cells
50
why is prophylactic cranial radiation important in addition to chemotherapy
because most chemotherapy agents do not cross the blood brain barrier
51
what is photodynamic therapy
photofrin is injected IV - percolates 48 hrs - laser light turns O2 toxic to destroy tumor - necrotic tissue removed via bronchoscope
52
priority goal in patient with lung cancer
1. effective oxygenation 2 pain management 3 realistic attitude
53
Nursing interventions should include
recognizing stresors/anxiety and offering support
54
what symptoms should a patient during treatment be taught to report

55
nursing goal should include
1 - cure 2 - control 3 - palliative
56
How will the nurse teach a quitting-smoker to avoid relapse?
Teach pt to recognize and avoid stressors.
57
How will the nurse teach quitting smoker to deal with the urge to smoke?
Teach distraction techniques (like shower or exercise)
