Clinical Lab Values and Diagnostic Testing, Bed Rest & Immoblity - Class 4 Flashcards
clinical lab values
electrolytes
hematology studies
electrolytes
changes in electrolytes values can cause a change in the pt’s presentation and our tx plan
sodium
hypernatremia
hyponatremia
potassium
hyperkalemia
hypokalemia
calcium
hypercalcemia
hypocalcemia
hematology studies
acid-base/arterial blood bass analysis
common hematology studies
blood values and common PT considerations
acid-base/arterial blood bass analysis
pH
partial pressure of oxygen
partial pressure of CO2
bicarbonate
what are acid-base/arterial blood bass analysis used for
used to check how well the lungs are available to move O2 into blood and CO2 out of the blood
pH
7.35 - 7.45
PaO2
80-100 mmHg
PaCO2
35-45 mmHg
HCO3-
22-28 mEq
common hematology studies
RBCs
hematocrit
hemoglobin
WBCs
platelets
RBCs
men: 4.2-5.4
women: 3.6-5.0
hematocrit
proportion of blood that is RBCs
men: 42-52%
women: 36-48%
hemoglobin
protein that carries O2
men: 14-17.4
women: 12-16
WBCs
immune system
4000-11000 per microliter
platelets
clotting/hemostasis
140-400
PT considerations
anemia
platelets
anemias –> > 10
therapy as indicated
no distinct precautions
what to expect from someone with >10 hemoglobin
anticipate poor cardiopulmonary reserve/limited endurance
monitor vital signs closely
> 10 hemoglobin sxs
exercise intolerance
DOE
tachycardia
pallor
hemoglobin <8
medically unstable
no tx
blood transfusion probable
hemoglobin <5
leads to heart failure and death
hemoglobin is 20
increased blood viscosity –> capillary blockage and tissue ischemia
thrombocytopenia –> platelets 50-140
low intensity progressive resistive exercise
aerobic exercise
thrombocytopenia –> platelets 30 to 50
AROM
walking ad lib
thrombocytopenia –> platelets <20 –> risk of
spontaneous bleeding
petechia
ecchymosis
prolonged bleeding time
thrombocytopenia –> platelets <20 –> therapy
contraindicated
minimal AROM
no brushing of teeth
are there side effects of bed rest and immobility
yes there are many
side effects of bed rest and immobility will occur
rapidly
only 1-2 weeks of immobility significantly reduces both metabolic and aerobic capacity
consequences of bed rest and immobility
