Chapter 42 Fluid And Electrolytes Flashcards
pressure within the capillaries
pushes fluid out of capillaries into the interstitial space.
Hydrostatic pressure
large proteins (colloids-albumin) can't go through the membrane so the fluid is into the capillaries
Oncotic pressure
Sodium values
136 to 145
Hypernademia –> Tented skin turgor and thirst
Hyponatremia–> hyperactive bowel sounds
Potasium values
3.5 to 5
Addison’s disease high K
Magnesium values
- 3 to 2.1mEq/L
- 65 to 1.05 mmol/L
Hypermagnesemia (Areflexia)–>loss of deep tendon reflex,hot flushed skin and diaphoresis.
Avocado high in Mg
Hypomagnesemia–> seizures, dysrhythmias
Chloride values
98 to 106
Diffusion is passive movement of electrolytes or
other particles down a concentration gradient (from areas of higher
concentration to areas of lower concentration).
Diffusion
Movement of water (or other
solute) from an area of lesser to one of greater concentration
osmosis
Movement across a
membrane, under pressure,
from higher to lower pressure
Filtration
Water loss exceeds electrolyte loss
Hypertonic dehydration
Phosphate values
3.0 to 4.5
Electrolytes afecting nerves junction and muscles
hypomagnesemia
Hypocalcemia
Calcium lavels
9 to 10.5
Hypocalcemia –> + Trousseau’s , hypotension
