Q

Erythropoietin client teaching

A

Monitoring BP
correct injection technique
reporting side effects

22
Q

Clients Receiving Epoetin Alfa what to monitor

A
BP
seizure activity
H+H
signs of thrombosis
dietary intake for essential nutrients
23
Q

Granulocyte CSF (G-CSF) function

A

colony stimulating factor

increases production of neutrophils

24
Q

Granulocyte/macrophage CSF (GM-CSF) function

A

colony stimulating factor

stimulates production of both neutrophils and macrophages

25
Colony-Stimulating Factors considerations
monitor for hypertension, bone pain, respiratory distress and ST-segment depression
26
Avoid Colony-Stimulating Factors with
clients with kidney and liver impairment
27
Colony-Stimulating Factors teaching
how to avoid infections and to report adverse symptoms
28
What to monitor in clients on Filgrastim (Neupogen)
``` VS S/Sx of infection CBC hepatic status bone pain ```
29
Platelet Enhancers cautions
use in caution in PT's with cardiac disease withhold 12 hours before and after radiation avoid injury
30
What to monitor with Platelet Enhancers
Monitor clients with hx of edema | Report Edema; change in urinary output or body weight or Bleeding; difficulty breathing
31
Anemia
Blood has reduced capacity to carry oxygen
32
Anemia can cause
Hemorrhage Excessive erythrocyte destruction Insufficient erythrocyte synthesis
33
Anemia symptoms
``` Pallor Decreased exercise tolerance Fatigue, dizziness and fainting Increased RR and HR Heart failure ```
34
Antianemic Agents
Vitamins and minerals | Enhance oxygen-carrying capacity of blood
35
Antianemic Agents examples
Most common are cyanocobalamin (B12), folic acid, and ferrous sulfate
36
Intrinsic Factor
Protein secreted by stomach cells | Required for vitamin B12 metabolism
37
Pernicious Anemia
Vitamin B12 deficiency | Sx can be reversed but nervous system damage may be permanent
38
Pernicious Anemia treatment
cyanocobalamin
39
Pernicious Anemia causes
Chronic alcoholism, fad diets, absorption diseases
40
Folic acid deficiency in pregnancy
linked to neural-tube defects
41
Cause of Folic acid deficiency
lack of sufficient dietary intake
42
Folic acid anemia absorption
does not need intrinsic factor to be absorbed | linked to pernicious anemia (decreased B12 causes decreased folic acid)
43
Antianemic Agents—Vitamin B12 and Folic Acid considerations
assess cause of anemia monitor RR and cardiac monitor K+ report SOB and edema
44
Iron uses
Essential for metabolism and energy
45
Ferritin and hemosiderin
maintain iron inside cells
46
Transferrin
transports iron to other body sites
47
Free iron
toxic | binds to protein complexes
48
Iron Deficiency tx
iron supplements
49
Iron Deficiency cause
Acute or chronic blood loss, peptic ulcer | Heavy menstruation, pregnancy, intensive athletic training
50
Iron supplements teaching
Take iron with food **Use straw to prevent staining teeth Report signs of bleeding
