Chapter 41: Fluid and Electrolyte & Acid Base Balance Definitions Flashcards
This body fluid compartment is inside the cell. What is this defined as?
Intracellular fluid (ICF)
This is a fluid that fills the spaces between most of the cells of the body and provides a substantial portion of the liquid environment of the body.
Interstitial fluid
When there is any direct increase of (bicarbonate) base or a decrease of metabolic acid which increases blood (bicarbonate) base by releasing it from it’s buffering function. What is this defined as?
Metabolic Alkalosis
Ex. Common causes include vomiting and gastric section. The respiratory compensation for metabolic alkalosis is hypoventilation. The decreased rate and depth of respiration allows carbonic acid to increase in the blood as seen by increased PaCO2. The need for oxygen may limit the degree of respiratory compensation for metabolic alkalosis.
This is a technique in which a vein is punctured through the skin by a sharp rigid stylet. Purpose is to collect a blood specimen, start an IV infusion, provide vascular access for later use, instill a medication, or inject a radiopaque or other tracer for special diagnostic examinations.
Venipuncture
Ex. Contraindicated in a site has signs of infiltration, thrombosis, or infection. S/Sx: red, tender, swollen, and possibly warm to the touch because exudate may be present.
If incompatible blood is transfused (a patient’s RBC antigens differ from those transfused) the patients antibodies trigger RBC destruction in a potentially dangerous immune response to the transfused blood components. What is this defined as?
Transfusion Reaction
This is a reflection of unmeasured anions in plasma. Healthcare providers use this lab test to help identify the specific cause of a patient’s acid-base imbalance. Where is this defined as?
Anion Gap
During alveolar hyperventilation, the lungs excrete too much carbonic acid (CO2 and water). The PaCO2 falls creating a deficit of carbonic acid in the blood which increases pH. This is usually short-lived, thus the kidneys do not that have time to compensate. what is this defined as?
Respiratory Alkalosis
Ex. When the pH of blood, CSF, and ICF increases acutely, cell membrane excitability also increases giving rise to neurological symptoms such as excitement, confusion, and paresthesias. If the pH rises high enough CNS depression may occur.
Negatively charged electrolytes. What is this defined as?
Anions
This test is used to monitor the patient’s acid-base balance. This test is this sample of arterial blood. What is this defined as?
Arterial blood gases (ABGs)
These are pairs of chemicals that work together to maintain normal pH of body fluids. What is this defined as?
Buffers
Ex. If there are too many free H+ ions, a buffer take them up so they no longer are free. If there are too few H+ ions, a buffer can release H+ ions to prevent an acid-base imbalance. Buffers work rapidly within seconds.
Fluid in each compartment exerts _______ an inward pulling force caused by particles in the fluid. What is this defined as?
Osmotic Pressure
These are positively charged electrolytes. What is this defined as?
Cations
This is a charged particle. What is this defined as?
Ions
Parenteral replacement therapy includes parenteral nutrition, IV fluid and electrolyte therapy (________), and blood and blood component (colloid) administration.
Crystalloids
This is the net effect of four forces, two that tend to move fluid out of capillaries and small venules and two that tend to move back into the capillaries and small venules. This is how fluid moves into and out of capillaries between the vascular and interstitial compartments. What is this defined as?
Filtration
Hypernatremia may occur in combination with ECV deficit, this combined disorder is called?
Clinical Dehydration
This is an element or compound that when melted or dissolved in water or other solvent dissociates into ions and can carry an electrical current. What is this defined as?
Electrolytes
This describes a condition that tends to make the blood relatively too acidic. There are two types respiratory and metabolic. What is that defined as?
Acidosis
These are also called IV pumps or infusion pumps, they deliver an accurate hourly IV infusion rate. These use positive pressure to deliver a measured amount of fluid during a specific unit of time ex. 125 mL/hr. What is this defined as?
Electronic Infusion Devices (EID)
This body fluid compartment is outside of the cell. What is this defined us?
Extracellular Fluid (ECF)
