INTRAVENOUS THERAPY Flashcards
Common method for replacing water, electrolytes and blood products and is also used for the continuous administration of drugs
Intravenous Therapy
- Continuous IV infusion
- Intermittent IV infusion
2 Methods are used to administer IV Fluids
Replaces fluid loss, maintains fluid balance, and serves as a vehicle for drug administration
Continuous IV infusion
Primarily to give IV drugs
Intermittent IV infusion
- Direct IV, IV push, IV bolus, IV infusion
- Most rapid route of absorption
Purposes of Intravenous Therapy
- Route that can be used for clients with compromised GI function or peripheral circulation
- Correct an underlying imbalance in fluids or electrolytes
Purposes of Intravenous Therapy
- Knowing IV sets and their drop factors
- Calculating IV flow rates
- Mixing and diluting drugs in IV fluids
- Gathering equipment
- Knowing the drugs and the expected and untoward reactions
Functions and Responsibilities of a Nurse during Drug Preparation
- Isotonic
- Hypertonic
- Hypotonic
TYPES OF IV FLUIDS
type of iv fluid that has no effects on the cell
- Isotonic
o NaCl or plain NSS or .9 NaCl
o The only compatible IVF in blood transfusion
o Restores circulatory volume, for hypovolemic hypotension and metabolic acidosis
Ex of Isotonic
type of iv fluid that causes cell to shrink
Hypertonic
type of iv fluid that causes cell to swell
Hypotonic
o D5W (carbohydrates in water)
o .45% NS
o .33% NS
o Treatment of cellular dehydration
o Note: NS = Normal Saline
Ex of Hypotonic
