Definition of isotonic solution?
Fluid that goes into the vascular space and stays there.
Example of isotonic solution?
0.9% NS,D5W, Lactated ringers
What is hypotonic solutions?
Used if isotonic solutions are contraindicated (ie. renal disease or cardiovascular disease). Causes water to go into vascular space and enter into cells to rehydrate.
Examples of hypotonic solutions?
0.45% NS, 0.33% NS
What are hypertonic solutions?
CONCENTRATED solutions (high alert medications). Water is REMOVED from cells back into the vascular space.
Example of hypertonic solutions?
3%NS, TPN, albumin, D10W, D5W, D5LR.

What does the RR do in acidosis?
Increases to excrete acids.
What does RR do in alkalosis?
Decreases to retain acids.
What can cause metabolic alkalosis?
GI suctioning or severe vomiting.
What can cause respiratory alkalosis?
Overstimulation of respiratory system = hyperventilation, hysteria, over ventilation.
Formula for medication dosages?
Desired dose/dose on hand x mL
