|
Classifications of cancer
chemotherapy drugs (2) |
1. Cell cycle specific 2. Cell cycle non specific
|
Cell cycle specific
|
Only have action during one specific phase of the cell cycle
|
Cell cycle non specific
|
Can have action during any phase of the cell cycle
|
Drug resistance
|
This limits the effectiveness of cancer chemotherapy. Similar phenomenon to antibiotics...
Most resistant cancer cells survive and cause tumor to become resistant to drug therapy. |
Common Chemo Side-Effects
|
Cancer cells replicate very rapidly as do some of the normal cells in the body. Chemotherapy
drugs cannot differentiate between cancer cells and normal cells in the body that replicate rapidly. This causes chemo side effects seen in the Bone marrow, GI tract cells, hair cells, gonads |
Low RBC
|
Anemia (need to follow hemoglobin and hematocrit... Need to transfuse if hematocrit falls
below 25%), nursing intervention: assess for anemia and monitor hemoglobin and hematocrit levels. Nursing diagnosis: fatigue. |
Thrombocytopenia
|
When platelet count of dips to 10,000 or below. Assess for bruising, petehaie, bleeding gums
(Pt should not use a toothbrush or dental floss with a low platelet count), nose bleeds, GI bleeding (black tarry stools, etc.), cerebral bleed. Nursing implication: put pressure on injection site to avoid hematoma (sometimes pressure dressing/sandbag is necessary) |
Stuff
|
Stuff
|
Nausea and vomiting
|
Administer anti-emetics PRN (Zofran, Etc.)
|
Diarrhea
|
Administer meds PRN. Nursing diagnosis: FVD, nutrition less than body requirements
|
Anorexia
|
Altered taste sensation, Nursing interventions: Nutritional supplements (Ensure), high calorie
foods |
Stomatitis / Mucosititis
|
Very painful. High risk for nutritional deficit. No treatment. Can sometimes see legions on the
lips. |
Alopecia (hair loss)
|
Not life threatening but can affect Pt psychologically. Good news is that the hair will grow back
but sometimes it grows back another color or texture. Nursing diagnoses: Distorted body image, self esteem. Nursing implication: discuss with Pt what they can do before the hair falls out. |
Fatigue
|
Major problem. Nursing diagnosis: activity intolerance... Fatigue can last for months after
chemotherapy has ended. |
