Isotonic
concentration of water and solutes= bloodstream values. Slowly increases H2O and Na+
0.9% NS and Lactated ringers
Isotonic fluids
Ringers lactate has a buffer (acidotic/alkalotic)- used in burn victims
Isotonic fluids
Only fluid that stays in the vascular space, does not have hypotonic or oncotic pressure
hydrostatic pressure
Pressure that tries to push out of the vessel

,NU 327 Pathophysiology Exam 2 2026-02-25
oncotic pressure
pressure created by protein, H2O and Na+ to get into the vessel
Homeostasis
Good fluid balance.
Moist membranes, normal HR and BP, no JVD, no tenting/edema, normal urine output
dehydration
cell shrinkage, dry mucous membrane, eyeballs sunken, low urine output, low BP/increased HR,
hypernatremic, decreased PaO2 (hypoxemia- low O2), decreased body function, tenting

Hypotonic fluid
Usually given incorrectly!
0.45% NS
0.225% NS
D5W (D5 or D5 water)- behaves as a hypotonic but labeled as isotonic.
D5 0.45% NS (1/2 D5, 1/2 NS)
D5 0.225%
Free water (drinking water)
hypotonic fluid overload
brain injury that cannot control fluid balance
drank a lot of water
near drowning in fresh water.
