NUR 209 Lecture Notes - Lecture 22: Magnesium Sulfate, Fluid Compartments, Extracellular Fluid
Document Summary
6: anticipate, identify, respond to possible imbalances. Fluid: approximately 60% of typical adult is fluid, varies with age, body size, gender, intracellular fluid, 2/3 of body fluid, skeletal muscle mass, extracellular fluid, intravascular: plasma, erythrocytes, leukocytes, thrombocytes, interstitial: lymph, transcellular: cerebrospinal, pericardial, synovial. 8: electrolyte concentrations differ in fluid compartments. Systemic routes of gains and losses: gain. Healthy people gain fluids by drinking and eating. Daily i&o of water are equal: loss. Skin loss: sensible due to sweating and insensible due to fever, exercise, and burns. Lungs: 300 ml everyday, greater with increased rr. Gi tract: large losses due to diarrhea and fistulas. 12: delirium, fluid overload, renal function, dehydration. Fluid volume imbalances: fluid volume deficit (fvd): hypovolemia, fluid volume excess (fve): hypervolemia. Causes of fvd: abnormal fluid losses, vomiting, diarrhea, sweating, gi suctioning, decreased intake, nausea, lack of access to fluids, third-space fluid shifts, due to burns, ascites, additional causes, diabetes insipidus, adrenal insufficiency, hemorrhage.
