IV certification - RWJIsotonic - ANS-No effect on cell volume
Hypotonic - ANS-Lower osmolality
Fluid will go into the cell, causing the cell to swell and burst
Hypertonic - ANS-Greater osmolality
Fluid will move out of the cell, causing the cell to shrink
Hypertonic solutions include: - ANS-D1/3NS
D10W, D50W
D1/2NS
D5NS
D5LR
Saline solutions >0.9% (NaCl 3%, NaCl 5%)
Hypotonic solutions include: - ANS-1/2 NS (0.9%)
D2.5W
1/4 NS (0.225%)
1/3 NS (0.33%)
Isotonic solutions include: - ANS-0.9% NS
LR
D5W
D5 1/4 NS
D10W - ANS-Hypertonic
D1/3NS - ANS-Hypertonic
D2.5%NS - ANS-Hypotonic
1/2NS - ANS-Hypotonic
D5W - ANS-Isotonic
Aldosterone - ANS-Released by the adrenal cortex
Na and water reabsorption at the renal tubules in exchange for potassium
, The effects of aldosterone release are to increase ___ and ____, but decrease ____ -
ANS-Na and water, K
Anti-diuretic hormone (ADH) - ANS-Stops diuresis causing water reabsorption in the
distal tubules
Released by the pituitary gland
Isotonic dehydration - ANS-The loss of sodium and water is equal
Caused by NG suctioning, hemorrhage, enemas, V/D
Treat with isotonic fluids
Hypotonic dehydration - ANS-More sodium is lost than water, resulting in low serum NA
levels resulting in water being drawn into cells
Cause: diuretics, sweating, vomiting, burns
Treat with hypertonic IVF or isotonic IVF
Hypertonic dehydration - ANS-More water is lost than sodium, resulting in higher Na
serum levels
Cause: DI, excess insensible water loss
Treat with D5W initially (isotonic), then switch to hypotonic (will draw fluid back into the
cells)
D5LR - ANS-Hypertonic
D50W - ANS-Hypertonic
D5 1/3 NS - ANS-Hypertonic
D5 1/2 NS - ANS-Hypertonic
NaCl 3% - ANS-Hypertonic
NaCl 5% - ANS-Hypertonic
1/4 NS (0.225%) - ANS-Hypotonic
1/3 NS (0.33% Nacl) - ANS-Hypotonic
LR - ANS-Isotonic
