Body Fluid | Fluid Balance | Edema | Dehydration and IV Solution | Acid-Base balance Acidosis Alkalosis |
---|---|---|---|---|
What is Homeostasis
A self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival
|
What is Osmosis
The force that draws water from a less concentrated solute through a selectively permeable membrane to a more concentrated solute
|
What is Edema
Accumulation of fluid in the interstitial space that can be localized or generalized
|
What is Hypotonic Dehydration
This type of dehydration consists of low serum osmolality causing fluid to leak from the vascular space into the interstitial space and cells causing the cells to swell.
|
What is Metabolic Acidosis
Decreased pH and decreased HCO3 is seen in severe diarrhea, diabetic ketoacidosis and lactic acidosis and causes which type of acid-base imbalance?
|
What is Extracellular
The name of the fluid compartment that is responsible for storage of 30% of body fluid
|
What is Diffusion
Particles or Solutes of liquids, gases, or solids move from an area of higher concentration to lower concentration
|
What is 3+ Deep pitting edema
The number on the scale used to describe pitting that takes 1-2 minutes for an indentation to return to normal
|
What is Hypotonic IV Solution
When fluid has been drawn out of the cells into the vascular space (causing cell shrinkage), this type of IV solution is used to rehydrate cells.
|
What is Respiratory Alkalosis
Increased pH and decreased PaCO2 is seen with hyperventilation and causes which type of acid-base imbalance?
|
What is Intracellular
The name of the fluid compartment that is responsible for storage of 70% of body fluid
|
What is Osmotic Pressure
The Pressure that pulls fluids into the vascular system so fluids and wastes can be excreted
|
What is 1+ Mild Pitting Edema
The number on the scale used to describe pitting that takes 1-6 seconds for an indentation to return to normal
|
What is Isotonic
Normal Saline, Lactated Ringers, and D5W are all what type of IV solution?
|
What is Respiratory Acidosis
Decreased pH and increased PaCO2 is seen with hypoventilation and respiratory failure and causes which type of acid-base imbalance?
|
What is Interstitial
The name of the fluid that is "between the cells"
|
What is Third Spacing
The accumulation of trapped extracellular fluid in a body space that is not perfused; and represents fluid loss because it is unavailable in the vascular system
|
What is 4+ Very Deep Pitting Edema
The number on the scale used to describe pitting that takes greater than 2 minutes for an indentation to return to normal
|
What is Hypertonic IV solution
D5NS, D5 1/2NS, and D5LR are all what type of IV solution?
|
What is Metabolic Alkalosis
Increased pH and increased HCO3 is seen with excessive vomiting, NG drainage, or excessive use of diuretics and causes which type of acid-base imbalance?
|
What is Transcellular fluid
The fluid compartment that consists of cerebral spinal fluid, synovial fluid, peritoneal fluid, pleural fluid
|
What is Thoracentesis
The name of the process that is used to remove fluid from the third space in the chest pleural space
|
What is 2+ Moderate Pitting edema
The number on the scale used to describe pitting that takes 10-25 seconds for an indentation to return to normal
|
What is Isotonic Dehydration
What type of dehydration is caused when the patient loses water and sodium equally?
|
What is renal and respiratory
What two regulatory systems are involved with compensation?
