Study Notes
Fluid and Electrolyte Key Terms and Concepts
- Active Transport: Movement of ions/molecules across a cell membrane from lower to higher concentration, requiring energy (ATP).
- Blood Urea Nitrogen (BUN): Measures nitrogen in blood from waste product urea, used to assess kidney function.
- Cations and Anions: Cations are positively charged ions (e.g., Na+, K+), anions are negatively charged ions (e.g., Cl-, HCO3-).
- Buffers: Substances that maintain blood pH by neutralizing excess acids/bases.
- Creatinine: Muscle metabolism waste product, measured to assess kidney function.
- Diffusion: Passive movement of molecules/ions from higher to lower concentration.
- Extracellular Fluid (ECF): Fluid outside cells, including interstitial fluid, plasma, and transcellular fluid.
- Filtration: Process where water and solutes are forced through a membrane by hydrostatic pressure.
- Fluid Volume Deficit (FVD): Condition of decreased fluid volume, often due to dehydration or blood loss.
- Fluid Volume Excess (FVE): Condition of increased fluid volume, often due to heart failure or kidney disease.
- Homeostasis: Body's ability to maintain stable internal environment despite external changes.
- Hydrostatic Pressure: Pressure exerted by a fluid due to its weight, important in fluid movement between compartments.
- Hypertonic: Solution with higher solute concentration than another solution, causing cells to shrink.
- Hypotonic: Solution with lower solute concentration than another solution, causing cells to swell.
Additional Fluid/Electrolyte Concepts
- Hyperkalemia: Elevated potassium levels in the blood, often due to kidney failure or excessive potassium intake.
- Hypokalemia: Low potassium levels in the blood, often due to diuretics or excessive loss through vomiting/diarrhea.
- Hypercalcemia: Elevated calcium levels in the blood, often due to hyperparathyroidism or malignancy.
- Hypocalcemia: Low calcium levels in the blood, often due to hypoparathyroidism or vitamin D deficiency.
- Hyperphosphatemia: Elevated phosphate levels in the blood, often due to kidney failure or excessive phosphate intake.
- Hypophosphatemia: Low phosphate levels in the blood, often due to malnutrition or alcohol abuse.
- Hypermagnesemia: Elevated magnesium levels in the blood, often due to kidney failure or excessive magnesium intake.
- Hypomagnesemia: Low magnesium levels in the blood, often due to malnutrition or chronic alcoholism.
- Hypovolemia: Decreased blood plasma volume, often due to dehydration or blood loss.
- Hypervolemia: Increased blood plasma volume, often due to heart failure or kidney disease.
- Interstitial Space: Space between cells in a tissue, filled with interstitial fluid.
- Intracellular Fluid (ICF): Fluid within the cells.
- Isotonic: Solution with same solute concentration as another solution, causing no net water movement.
- Oncotic Pressure: Osmotic pressure exerted by proteins (primarily albumin) in blood plasma, pulling water into the circulatory system.
- Osmosis: Movement of water across a semipermeable membrane from lower to higher solute concentration.
- Osmotic Pressure: Pressure needed to prevent water flow across a semipermeable membrane.
- Passive Transport: Movement of ions/molecules across a cell membrane without energy, driven by concentration gradients.
Acid-Base Imbalances
- Acid: Substance that releases hydrogen ions (H+) in solution.
- Base: Substance that accepts hydrogen ions (H+) in solution.
- Bicarbonate (HCO3-): Major buffer in the blood that helps maintain pH balance.
- Carbon Dioxide (CO2): Metabolism waste product that combines with water to form carbonic acid.
- Hydrogen Ions (H+): Positively charged ions that determine solution acidity.
- Metabolic Acidosis: Condition with decreased blood pH due to acid accumulation or bicarbonate loss.
- Metabolic Alkalosis: Condition with increased blood pH due to bicarbonate accumulation or acid loss.
- Respiratory Acidosis: Condition with decreased blood pH due to CO2 accumulation from hypoventilation.
- Respiratory Alkalosis: Condition with increased blood pH due to CO2 decrease from hyperventilation.
- Arterial Blood Gas (ABG): Test measuring oxygen, carbon dioxide, and pH in arterial blood to assess respiratory and metabolic function.
Fluid and Electrolyte Imbalance Clinical Manifestations
- Hypernatremia: Thirst, confusion, muscle twitching, and seizures.
- Hyponatremia: Nausea, headache, confusion, and seizures.
- Hyperkalemia: Muscle weakness, cardiac arrhythmias, and fatigue.
- Hypokalemia: Muscle weakness, cramps, and cardiac arrhythmias.
- Hypercalcemia: Nausea, vomiting, constipation, and confusion.
- Hypocalcemia: Muscle cramps, tingling, and seizures.
- Hypermagnesemia: Nausea, vomiting, and muscle weakness
- Hypomagnesemia: Muscle cramps, seizures, and cardiac arrhythmias
Intravenous Fluids (IVF)
- Isotonic Fluids: (e.g., 0.9% NaCl, Lactated Ringer's) Have same osmolarity as blood. Used for fluid volume deficit, dehydration, and shock.
- Hypertonic Fluids: (e.g., 3% NaCl, Dextrose 10%) Have higher osmolarity than blood. Used to treat severe hyponatremia and cerebral edema.
- Hypotonic Fluids: (e.g., 0.45% NaCl) Have lower osmolarity than blood. Used to treat hypernatremia and intracellular dehydration.
Note: This summary covers many of the primary concepts. For a thorough understanding, additional research and class materials are recommended.
