List Four Indications for Vascular Access
|
Fluid or blood administration.
Medication administration. Blood sampling. Precautionary in a patient at risk of rapid deterioration. |
|
Peripheral venous access
|
Access into peripheral veins of the arms, legs, or the external jugular vein
|
|
List at least three examples of colloids
|
Plasma protein fraction (Plasmanate)
Salt-poor albumin Dextran Hetastarch (Hespan) |
|
Colloids
|
IV solutions containing large proteins. These remain in the vascular space for a longer time than crystalloids.
|
|
Why are colloids not typically used in the field?
|
Cost
Short shelf life Special storage requirements |
|
Crystalloids
|
IV solutions that contain electrolytes but lack larger proteins contained in colloids.
|
|
Isotonic
|
solutions on opposite side of a semi-permeable membrane are equal in concentration.
|
|
Hypertonic
|
State in which there is a higher solute concentration on one side of a semipermeable membrane than on the other side.
|
|
Hypotonic
|
State in which there is a lower solute concentration on one side of a semipermeable membrane than on the other side.
|
|
Lactated ringer's and Normal saline are considered ________________
(Isotonic, Hypertonic, or Hypotonic) compared to blood. |
Isotonic
|
|
D5W is considered ________________ (Isotonic, Hypertonic, or Hypotonic) compared to blood.
|
Hypotonic
|
|
List at least four items that must be checked when inspecting drugs and IV solution.
|
Clarity--no particles should be visible.
Color--no discoloration should be present. Packaging--should be intact and undamaged. Expiration date. |
|
Microdrop tubing administers ____ gtts/mL
|
60
60drops= 1 mL |
|
A venous constriction band should never be left on longer than _____ minutes.
|
2 minutes
|
|
Large gauge catheters are defined as all catheters ______ gauge or larger.
|
18 gauge
|
|
The larger the gauge number, the ____________ (larger, smaller) the catheter.
|
smaller
|
|
A cannula gauge of ______ or larger is required for blood administration.
|
16 gauge or larger
|
|
The most common factor affecting IV flow rates is:
|
Failure to remove the IV constricting band.
|
|
Extravasation
|
Leakage of fluid or medications from a blood vessel.
|
|
Infiltration
|
Accumulation within the body tissues of blood and fluid that has escaped from a blood vessel.
|
|
List 12 complications of peripheral IV access.
|
Pain
Allergic reaction Pyrogenic reaction Infection Catheter shear Inadvertent arterial puncture Circulatory overload Thrombophlebitis Thrombus formation Air embolism Necrosis Anticoagulants increase the risk of hematoma or infiltration. |
|
Hemoconcentration
|
Elevated number of red and white blood cells. Can be caused by leaving a constricting band on too long.
|
|
Hemolysis
|
Destruction of red blood cells. can be caused by vigorous shaking of blood tubes or using too small a catheter for blood draws.
|
|
List four contraindications to the use of intraosseous fluid administration.
|
Use of the IO is for unstable patients only.
Osteoporosis or osteogenesis imperfecta. Fracture of the extremity. Recent use of the site for IO. Insertion through cellulitis, burns, or infection should be avoided. |
|

|
Diffusion
|
movement of a solute (particle) from areas of higher concentration to areas of lower concentration across a semi-permeable membrane
|
|
Osmosis
|
Movement of water across a semi-permeable membrane from areas of lower solute concentration to areas of higher solute concentration.
|
|
