in metal needles, the butefly needle is more likely to infilarate (damgae the vein and allow fluid to leak inot the interstitial spaces)than a plastic chatheter
Indications for IV theraphy
- Expand intravascular volume
- Correct an underlying imblance in fluids or electrolytes
- Compensae for an ongoing problem that is affecting either fluid or electroytes
Signs ans symptroms of electrolyte imbalance

- mucle cramps or twitching
- Elevated temp
