Q

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, tripyrifuck (d ko mbsa ulit) basta TPTZ or bathophenanthroline

23
Q

Processes in which electrolytes are essential.

A
Volume and osmotic regulation
Myocardial rhythm and contractility
Cofactors in enzyme regulation
Regulation of ATPase ion pumps
Acid-base balance
Blood coagulation
Neuromuscular excitability
Production and use of ATP from glucose
24
Women have lower average water content than males bec?
Higher fat content
25
Average water content of the human body
40-75% but also depends on body weight
26
Fluid inside the cells
Intracellular fluid
27
Water that Surrounds the cells in the tissue
Interstitial cell fluid
28
With energy; acts against concentration gradient
Active transport
29
Accounts for about 1/3 of total body water
Extracellular fluid
30
The passive movement of ions across a membrane
Diffusion
31
Percentage of water in normal plasma
93%
32
Water in plasma
Intravascular extracellular fluid
33
Normal plasma osmolality
Approx. 275-295m Osm/kg of plasma H2
34
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)
Osmolality
35
Measured in millimoles per liter (w/v)
Osmolarity
36
Osmolarity is inaccurate in cases of:
Hyperlipidemia and hyperproteinemia For urine specimens In presence of osmotically active substances (ex. alcohol and mannitol)
37
Enumerate the transport processes
Active transport | Passive transport
38
High osmolality means that there is less water than solute
Water deficit
39
Low osmolality means that there is more water than solute
Water excess
40
Hypernatremia means that there is less water than sodium
Water deficit
41
Hyponatremia means that there is more water than sodium
Water excess
42
ADH effect on water
ADH prevents water loss
43
ADH is produced where?
Hypothalamus but stored and released by the posterior pituitary gland
44
Explain osmolality regulation/correlation
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.
45
It is the parameter to which the hypothalamus responds
Osmolality
46
Sodium concentration in plasma is affected by:
Osmolality | Blood volume
47
Clinical significance of osmolality
- the parameter to which hypothalamus responds | - affects the sodium concentration in plasma
48
Shits that have Normally high osmolality
Sodium, urea, glucose
49
How: Calculation of osmolality
D ko rin maintindihan, pakibasa na lang tapos explain niyo sakin. Thanks.
50
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
Calculation of osmolality????
51
Reference ranges of water
``` Serum: 275-295 mOsm/kg Urine (24hr): 300-900 mOsm/kg Urine/serum ratio: 1.0-3.0 Random urine: 50-1200 mOsm/kg Osmolal gap: 5-10 mOsm/kg ```
