Aemt Test Flashcards
Phospholipid Bilayer
The cell membranes double layer.
Electrolyte
A charged atom or compound
Interstitial
Water between the vascular system and the surrounding cells.
Crystalloid solution
Iv solution that contains compounds that quickly disassociate in solution and can cross membranes.
Normal saline
.9% sodium chloride
Macrodrip Set
Allows for rapid fluid flow into vascular system
D5W
5% dextrose in water
Sclerosis
Hardening of a vein from scar tissue after repeated cannulation
Bolus
In one mass
Nebulizer
Device for producing a fine spray or mist
Sodium/potassium pump
The mechanism by which the cell brings in two k+ ions and releases Na+ ions
Osmotic pressure
Pressure created against the cell wall
Intravascular
Water portion of the circulatory system surrounding the blood cell
Colloid solution
Contains compounds that are too large to pass out of the capillary membranes
Homeostasis
The balance of all systems of the body
Ionic concentration
The amount of charged particles found in a particular area
Local reaction
Mild to moderate allergic reaction occurring in a localized area
Volume on hand
The amount of fluid you have an IV bag or a vial of medication
Third spacing
Shifting fluid into the tissues, creating edema.
Selective permeability
Allowing compounds into the cell based on the cells current needs.
Microdrip set
Allows for carefully controlled fluid flow
Contaminated sticks
The puncturing of an emergency care providers skin with a catheter that was used on a patient
Air embolus
The presence of air in the vein
Acidosis
Results from an accumulation of acids in the body
Lactated ringers solution
A sterile crystalloid isotonic iv solution
Flash chamber
Fills with blood to help indicate when a vein is cannulated
