Q

Into plus Fe

Explain serum iron analysis

A

Acidification using HCl to convert ferrous ion to ferric ion. Addition of glycolic acid or ascorbic acid to reduce ferric ion to shit (d ko mbsa HO). Change in solution’s color as the color indicator, tripyridyltriazine (TPTZ) or bathophenanthroline

Q

Into plus Fe

Women have lower average water content than males bec?

A

Higher fat content

26
Q

Into plus Fe

Average water content of the human body

Water that Surrounds the cells in the tissue

A

Interstitial cell fluid

29
Q

Into plus Fe

With energy; acts against concentration gradient

A

30
Q

Into plus Fe

Accounts for about 1/3 of total body water

A

Extracellular fluid

31
Q

Into plus Fe

The passive movement of ions across a membrane

A

Diffusion

32
Q

Into plus Fe

Percentage of water in normal plasma

A

93%

33
Q

Into plus Fe

Water in plasma

A

Intravascular extracellular fluid

34
Q

Into plus Fe

Normal plasma osmolality

A

Approx. 275-295m Osm/kg of plasma H2

35
Q

Into plus Fe

A physical property of a solution that is based on the concentration of solutes per kilogram of solvent expressed as millimoles per kg of solvent (w/w)

A

Osmolality

36
Q

Into plus Fe

Measured in millimoles per liter (w/v)

A

Osmolarity

37
Q

Into plus Fe

Osmolarity is inaccurate in cases of:

A

Hyperlipidemia and hyperproteinemia
For urine specimens
In presence of osmotically active substances (ex. alcohol and mannitol)

38
Q

Into plus Fe

Enumerate the transport processes

A

Active transportPassive transport

39
Q

Into plus Fe

High osmolality means that there is less water than solute

A

Water deficit

40
Q

Into plus Fe

Low osmolality means that there is more water than solute

A

Water excess

41
Q

Into plus Fe

Hypernatremia means that there is less water than sodium

A

Water deficit

42
Q

Into plus Fe

Hyponatremia means that there is more water than sodium

A

Water excess

43
Q

Into plus Fe

ADH effect on water

A

ADH prevents water loss

44
Q

Into plus Fe

ADH is produced where?

A

Hypothalamus but stored and released by the posterior pituitary gland

45
Q

Into plus Fe

Explain osmolality regulation/correlation

A

If High osmolality is sensed, hypothalamus is stimulated to produce ADH and the sensation of thirst. Being thirsty, one is compelled to consume more fluids not unless one if of old age, an infant, with mental impairment or just lazy. Consuming more fluids will increase water content in ECF that will dilute elevated solute and will eventually lower osmolality.

46
Q

Into plus Fe

It is the parameter to which the hypothalamus responds

A

Osmolality

47
Q

Into plus Fe

Sodium concentration in plasma is affected by:

A

OsmolalityBlood volume

48
Q

Into plus Fe

Clinical significance of osmolality

A

-the parameter to which hypothalamus responds-affects the sodium concentration in plasma

49
Q

Into plus Fe

Shits that have Normally high osmolality

Q

Into plus Fe

How: Calculation of osmolality

A

D ko rin maintindihan, pakibasa na lang tapos explain niyo sakin. Thanks.

51
Q

Into plus Fe

An estimate of the true osmolality or to determine the osmolal gap -the difference bet the measurement and calculated osmolality -indirectly indicates the presence of the osmotically active substances other than sodium, urea or glucose

A
