Chapter 42 Fluid and Electrolytes Flashcards
Acidosis
Alkalosis
Anion Gap
Arterial Blood Gases (ABGs)
Autologous Transfusion
Buffers
Colloid Osmotic Pressure
AKA oncotic pressure. Inward pulling force caused by blood proteins that help move fluid from the interstitial area back into the capillaries.
Colloids
Proteins such as Albumin
Crystalloids
ECF Extracellular Fluids
Fluid outside the cells
ECV Deficit
Present when there is insufficient isotonic fluid int the extracellular compartment.
ECV Excess
Occurs when there is too much isotonic fluid in the extracellular compartment (edema)
Extravasation
Hydrostatic Pressure
Force of the fluid pressing outward against a surface.
Hypercalcemia
Hypercalcemia
High calcium; common in patients with lung and breast cancer because cancer cells secrete chemicals into the blood related to PTH.
Hyperkalemia
High potassium; at risk are patients with oliguria and patients that use salt substitutes.
Muscle weakness, life threatening dysrhythmias, cardiac arrest
Hypermagnesemia
Hypernatremia
Water deficit
Hypertonic
Fluid tonicity is more concentrated than the blood. Water from inside of the cell leaves to the outside causing the cell to shrink.
D5LR, 3%NS, NS With K
Hypocalcemia
Low calcium. Common in patients that have developed pancreatitis because calcium binds to undigested fat in feces and is excreted.
Examples:
Hypokalemia
Low potassium; common causes diarrhea, vomiting, k wasting diuretics.
Muscle weakness that can affect respiratory muscles, life threatening dysrhythmias.
Hypomagnesemia
Hyponatremia
Water intoxication
