19
Q

PT considerations

A

anemia

platelets

20
Q

anemias –> > 10

A

therapy as indicated

no distinct precautions

21
Q

what to expect from someone with >10 hemoglobin

A

anticipate poor cardiopulmonary reserve/limited endurance

monitor vital signs closely

22
Q

> 10 hemoglobin sxs

A

exercise intolerance

DOE

tachycardia

pallor

23
Q

hemoglobin <8

A

medically unstable

no tx

blood transfusion probable

24
Q

hemoglobin <5

A

leads to heart failure and death

25
Q

hemoglobin is 20

A

increased blood viscosity –> capillary blockage and tissue ischemia

26
Q

thrombocytopenia –> platelets 50-140

A

low intensity progressive resistive exercise

aerobic exercise

27
Q

thrombocytopenia –> platelets 30 to 50

A

AROM

walking ad lib

28
Q

thrombocytopenia –> platelets <20 –> risk of

A

spontaneous bleeding

petechia

ecchymosis

prolonged bleeding time

29
Q

thrombocytopenia –> platelets <20 –> therapy

A

contraindicated

minimal AROM

no brushing of teeth

30
Q

are there side effects of bed rest and immobility

A

yes there are many

31
Q

side effects of bed rest and immobility will occur

A

rapidly

only 1-2 weeks of immobility significantly reduces both metabolic and aerobic capacity

32
Q

consequences of bed rest and immobility

A

CV

hematologic

MS

pulmonary

metabolic/endocrine/ electrolytes
