Q

What are 2 goals of Intravenous Therapy?

A
  1. To maintain fluid, electrolyte and energy demands when patients are limited in their intake
  2. To prevent or correct fluid and electrolyte disturbance from excess losses

Q

What is a crystalloid IV solution?

A

Solutions that contain small molecules that flow easily across semipermeable membranes.

Distinguished by relative tonicity to plasma:
Hypertonic- higher concentration of electrolytes compared to Extracellular fluid(ECF)
Isotonic- same concentration or tonicity compared to ECF
Hypotonic – lower concentration/tonicity compared to ECF

Q

What is a Colloid IV solution?

A

They contain protein or starch that does not cross semipermeable membranes, staying only in the intravascular space
They increase osmotic pressure, which then increases the vascular volume
Can be used for a profound bloodloss
