Homeostasis ABG

Living organisms maintain internal stability when encountering external stimuli by the self-regulating process of homeostasis.
Sodium is the primary cation in the ECF, and potassium is in the ICF.
Fluid overload may be caused by intravenous fluid therapy.
Crackles in the lungs can indicate fluid overload.
Hyponatremia is the most common electrolyte disturbance.
Clients who have kidney disease must be careful of their potassium intake.
Urine output should be evaluated before administering potassium.
Potassium should never be administered intravenously by IV push due to the risk of dysrhythmias and rebound hyperkalemia.
Three percent sodium chloride should be administered via an infusion pump for hyponatremia.
People 65 years and older are susceptible to fluid volume deficit due to less water volume, potential renal insufficiency, and prescribed medications.
Cardiac monitoring should be used when hyperkalemia or hypokalemia is present to detect dysrhythmias.
Urine output is decreased in SIADH, which makes it very concentrated. There is too much fluid in the blood and not enough urine output. This balance must be corrected to achieve homeostasis.
Urine output is increased in diabetes insipidus, which causes an increase in osmolality, due to a lack of antidiuretic hormone.
Vomiting and diarrhea can cause metabolic alkalosis.
A positive Chvostek’s sign and Trousseau’s sign indicate hypocalcemia.
Metabolic alkalosis occurs when the pH level is greater than 7.45 due to an increase in serum bicarbonate. Bicarbonate is an alkalotic substance, which acts as the primary pH buffer system. Carbon dioxide (CO2) is an acidic substance. The pH of the serum becomes alkalotic when there is an increase in bicarbonate due to malfunctions in the renal system reabsorption rates.
Pathophysiology
Bicarbonate is an alkalotic substance that acts as the primary pH buffer system. CO2 is an acidic substance. The pH of the serum becomes alkalotic when there is an increase in bicarbonate due to malfunctions in the renal system reabsorption rates. Metabolic alkalosis results when there is excessive renal hydrogen loss, intracellular shift of hydrogen ions, retention or addition of bicarbonate ions, or gastrointestinal loss of hydrogen ions.
Some processes that may result in metabolic alkalosis include vomiting, nasogastric suctioning, ingestion of exogenous sodium bicarbonate, and diuretic use. Bicarbonate is found in calcium antacids, and the excessive ingestion of the antacids may lead to kidney failure. Additionally, the antacids increase the risk of metabolic alkalosis because they increase the pH level.
The environment of the stomach is acidic with a pH of 1.5 to 3.5. Parietal cells in the mucosa of the stomach secrete hydrogen. Metabolic alkalosis may occur if large amounts of gastric secretions are lost such as vomiting or gastric suctioning because of the loss of hydrogen chloride, an acidic substance that is in gastric secretions. The loss of hydrogen chloride results in an increase in bicarbonate and metabolic alkalosis. Bicarbonate balance in the body is maintained when the renal system is functioning effectively, and excess bicarbonate is excreted. If renal dysfunction exists, metabolic alkalosis will occur as bicarbonate increases. The body’s self-regulating process for hypercarbia may increase bicarbonate. CO2 is retained when an individual experiences hypoventilation, and pH is decreased. The renal system attempts to compensate by retaining bicarbonate to raise the pH.
