What is a hypotonic IV solution?
- -More water than electrolytes
- -Water moves from ECF to ICF by osmosis
- -Usually maintenance Fluids
What is an isotonic solution?
- -Expands only ECF
- -No net loss or gain from ICF
What is a hypertonic solution?
- -Initially expands and raises the osmolality of ECF
- -Requires frequent monitoring of BP, lung sounds, and serum sodium levels
What is D5W?
- -Provides 170 cal/L
- -Free water, moves into ICF, increases renal solute to excretion
- -Used to replace water loss and hyponatremia
- -Does not provide electrolytes
What is Normal Saline (NS)?
- -No calories
- -More NaCl than ECF
- -30% stays in IV
- -70% moves out of IV
- -Does not change ICF
- -preferred fluid for immediate response, risk for fluid overload
- -Compatible with most meds
What is Lactated Ringer's?
- -More similar to plasma than NS
- -Has less NaCl, had K, Ca, Po34, lactate
- -Expands ECF
What is D5(1/2)NS
- -Common maintenance fluid
- -KCl added for maintenacne or replacement
What is D10W?
- -Provides 340 kcal/l
- -Free water
- -Limit of dextrose concentration may be infused peripherally
