Flashcards in Hematologic Disorders 3 Deck (20):
1
Special considerations for hematologic disorders: should make sure to look at changes with this
coagulation
2
consider these with respect to changes in coagulation in pts with hematologic disorders:
- increased risk of thrombus
- increased work for heart
- breathing
- tissue perfusion
3
Platelet disorders are very important to consider with respect to this! (PT)
exercise prescription
4
normal platelet range
150,000-400,000 per microliter of blood
5
PT prescription: platelet range = 40-60,000
- keep exercise in low-load (1-2#) resistance
- OK for walk, bike, ADLs
6
PT prescription: platelet range = 20-40,000 per microliter of blood
- low intensity
- no resistance
7
PT prescription: platelet range = below 10,000 per microliter of blood means the pt is at risk for
spontaneous bleed
8
Why must clotting precautions be taken with a pt who has splenomegaly?
Splenomegaly is usually associated with rapid destruction of blood cells
9
PT implications with splenomegaly
Avoid activities or positions that could traumatize abdomen or increase pressure
10
What can exercise and sports do with respect to blood volume and erythrocytes for pts with hematologic disorders?
- can increase blood volume (plasma) immediately
- increase erythrocytes over time
11
Blood doping through:
exogenous EPO
12
Blood doping through exogenous EPO can increase these in pts with hematologic disorders:
- blood viscosity
- thrombus formation
**risky process**
13
In general, there is a possible indication of hypovolemia any time there's a combination of:
- systolic BP drop of 20 points or more
- Increased HR of 15 BPM or more
14
What is the most likely cause of hypovolemia in pts with hematologic disorders?
dehydration
15
What are possible causes of hypovolemia in pts with hematologic disorders?
- dehydration (most likely)
- diarrhea
- slow GI bleed
- May be normovolemic but on antihypertensives
16
Blood transfusions: Modern techniques available to only administer the necessary component (what are they)
- Packed RBCs
- Plasma
17
Packed RBCs needed for
anemia
18
Plasma needed for
coagulation deficiencies
19
Recombinant human erythropoietin products:
- rHuEpo
- EPO
- Epogen
