0-20
increases with age
4
Q
WBC
A
45000-10000
5
Q
Na
A
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
6
Q
K
A
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
7
Q
Cl
A
96-106 gastric juice (hydrochloric acid) with Na, regulates plasma osmolality participates in the chloride shift chemical buffer
8
Q
Ca
A
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
9
Q
PO4
A
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
10
Q
Mg
A
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’
11

BUN
A
8-20
critical >100
12
