Lab Values Flashcards
(36 cards)
RBC
male 4.6-6.2
female 4.2-5.2
or memorize 4.2-6.2
Hgb
male 14-18
female 12-16
ESR -erythrocyte sedimentation rate
0-20
increases with age
WBC
45000-10000
Na
135-145 most abundant cation in ECG plasma osmolality maintains blood volume assists in nerve transmission and muscle contraction Aldosterone causes Na retention ANP causes NA excretion
K
3.5-5.0 most abundant cation in ICF ICF osmolality nerve conduction and muscle contraction metabolism of CHO, fats, proteins Aldosterone causes K excretion ACIDOSIS promotes exchange of K for H in the cell
Cl
96-106 gastric juice (hydrochloric acid) with Na, regulates plasma osmolality participates in the chloride shift chemical buffer
Ca
8.5-10 mainly in bones and teeth muscular contraction and relaxation cardiac function blood clotting enzyme activation nerve function Ca absorbed in intestine with help Vit D PTH increases Ca absorption Calcitonin decreases plasma CA
PO4
2.5-4.5 major anion in ICF component of bone ATP-adenosine triPHOSPHATE, DNA, RNA PTH decreases plasma PO4 Calcitonin increases plasma PO4??? this true
Mg
1.5-2.5
enzyme activation reactions, CHO metabolism
intracellular production+ utilization of ATP
protein + DNA synthesis
sedation effect on CNS
causes neuromuscular irritability think ‘reflexes’
BUN
8-20
critical >100
Cr
0.6-1.2
platelets
150000-400000
PT
11-15 seconds
INR
1 “normal”
2-3 (sometimes 4) therapeutic
PTT
60-70 seconds
1.5-2.5 x normal is considered therapeutic
aPTT
30-45 seconds
1.5-2.5 x normal is considered therapeutic
total cholesterol

30-70
LDL
under 130
triglycerides
under 200
pH
7.35-7.45
PaO2 partial pressure of oxygen
80-100
