Replace the tubing every ___
72 hours
Replace solution bottle (or bag) every ___
24 hours
Change blood tubing every ___ or after ___ units
4 hours; 2 units
2 types of IV solutions
crystalloid and colloid
These solutions stay in the vascular compartment expanding vascular volume
isotonic solution
used to provide free water and treat cellular dehydration. These solutions promote waste elimination by the kidneys.
hypotonic solution
draw fluid out of the intracellular and interstitial compartments into the vascular compartment, expanding vascular volume
hypertonic solution
this isotonic solution should not be given to patients with liver disease or blood pH > 7.5
lactated ringer’s
this isotonic solution should not be given to patients at risk for increased ICP
D5W / 5% dextrose in water
Do not administer to clients at risk for increased intracranial pressure or third-space fluid shift, hypotension, neurosurgery, burns, trauma, or low serum protein levels from malnutrition or liver disease
0.45% and 0.33% NaCl
Do not administer to clients with kidney or heart disease or clients who are dehydrated. Watch for signs of hypervolemia
D5NS, D5 1/2 NS, D5LR
- Contain large molecules such as proteins that do not readily pass through the capillary membrane.
- referred to as volume expanders
- expensive, short half-lives, require refrigeration
colloid solutions
These solutions are commonly used to:
- Increase blood volume following severe blood loss
- Replace blood components
- Supplementation of nutrients / needs
colloid solutions
Consists of an insertion spike, a drip chamber, a roller valve or screw clamp, tubing with secondary ports, and a protective cap over the connecter to the IV catheter
infusion administration sets
The insertion spike is kept ___
sterile
A macrodrip drip chamber delivers between ___ drops (abbreviated gtts) per milliliter of solution.
