hi! I'm Joe, just got accredited as an EMT-A last week. Learning a lot on this site already. =D

Yep! It was one of the more memorable days of school.

an example of an isotonic solution would be normal saline solution. Isotonic basically means the solute concentration in the saline and in the bloodstream are equal so there would not be a shift in the concentration gradient. hypertonic solution would be like D50W. Lots of sugar molecules in the D50W, not as many in the bloodstream. This will cause water to move from the interstitial spaces into the bloodstream in order to equalize solute concentration on both sides of the venous system. hypotonic solution would be one that has less molecules in the solution as opposed to the concentration of molecules in the interstitial space. This would cause the shift of water from the venous system into the interstitial space.. hope that makes sense =D
