This is when you have a high concentration of solute (ie. Na) in your blood in contrast to a low concentration of water in the blood.

What is the Pathophysiology of hypernatremia?
--> causes of hypernatremia --> increased serum osmolality --> water shifts from cell to plasma --> cells shrink ---> manifestation
What factors stimulate an increase in ADH secrection?
ADH secretion is stimulated by increase in plasma osmolarity. Example:ingestion of Na+ will cause the plasma osmolarity to increase and trigger the pituitary gland to produce ADH.
Is a solution outside of a cell contains a greater concentration of dissolved particles than the contents of the cell the solution is said to be what?
Hypo-osmotic, it depends on the osmolality, if the osmolality is higher inside the cell its called hypotonic.
What test to determine high protein in blood?
There are three tests that can be carried to determine the high protein in bloods. These tests includes: Erythrocytedimentation rate, C-reactive protein, and Plasma viscosity.
When was plasma discovered?
Plasma was discovered by using a Crookes tube, wherein air is ionized in an electrical discharge tube, through the application of a high voltage. It was discovered by Sir William Crookes in 1879.
What is the osmolality of an isosmotic solution with plasma?
The osmolality of isosmotic solution is 300milliosmolar.
What is the purpose of measuring plasma osmolality?
you seriously don't know this??
What stimulates adh secretion from the posterior pituitary?
increased plasma osmolality
What is mannitol therapy?
Mannitol is used to treat cerebral edema (swelling of brain cells - this does not make you smart, this makes you have coma). Mannitol has the ability to increase plasma osmolality but cannot pass through cell membrane. When plasma ormolality is higher than the cell osmolality due to Mannitol in plasma, the cell tries to balance it by letting water pass through cell membrane into plasma. This reduces edema.
What is the Pathophysiology of hypernatremia?
--> causes of hypernatremia --> increased serum osmolality --> water shifts from cell to plasma --> cells shrink ---> manifestation
Why does IV contrast cause fluid shifts?
its to do with osmotic pressure and osmolality of the iv contrast, usually when a hypertonic solution is injected it pushes the ECF (extra cellular fluid) into blood plasma, this is because the solution has a greater osmotic pressure and osmolality than normal fluid.
What is the urine osmolality test?
Urine osmolality test. Urine osmolality is a measurement of the number of dissolved particles in urine.
Will glucose effect osmolality?
Glucose is a substance that will increase a solutions osmolality.
What is the difference between high definition and plasma television?
High definition refers to the quality of the picture, and plasma refers to the type of screen. All plasmas will be high definition, but not all high definition TVs will be plasma.
What are osmoles?
Osmosis? Osmolality? Osmolarity?
What factors stimulate an increase in ADH secrection?
ADH secretion is stimulated by increase in plasma osmolarity. Example:ingestion of Na+ will cause the plasma osmolarity to increase and trigger the pituitary gland to produce ADH.
What is hocm?
HOCM is an acronym for several different things such as Hypertrophic Cardiomyopathy and Hypertrophic Obstructive Cardiomyopathy. It also stands for High Osmolar Contrast Medium and High Osmolality Contrast Medium.
