What will happen to his electrolyte balance? The excess water will be excreted by his kidneys maintaining the electrolyte balance in his body fluids. The excess water his kidneys cannot excrete will dilute body fluids and lead to an imbalance in electrolytes. The excess water the patient drinks will increase the concentration of electrolytes in his extracellular fluid, leading to a balance of electrolytes in his urine. His kidneys will become concentrated by the loss of water and cause an electrolyte imbalance. The excess water his kidneys cannot excrete will dilute body fluids and lead to an imbalance in electrolytes. The bicarbonate ion is an example of a(n) __________. base base Which of the following dissociates into ions when placed in water? glucose electrolyte Which of the following statements about ECF is correct? It is found inside cells. It is made up of fluids such as plasma and interstitial fluid. It accounts for about 60% of the total body water. It has the same composition as the ICF. It is made up of fluids such as plasma and interstitial fluid. The following represents the main locations fluids are found in the human body. Rank these body fluids in order from the fluid that accounts for most in the human body to the fluid that accounts for the least. plasma, cytosol (intracellular fluid), interstitial fluid cytosol (intracellular fluid), plasma, interstitial fluid interstitial fluid, cytosol (intracellular fluid), plasma cytosol (intracellular fluid), interstitial fluid, plasma cytosol (intracellular fluid), interstitial fluid, plasma Art-based Question Chapter 25 Question 7 ... What is a major function of potassium ions in the body? activating enzymes forming hydroxyapatite salts in osseous tissue repolarization of neurons and muscle cells after action potential maintaining osmotic pressure in the extracellular fluid (ECF) repolarization of neurons and muscle cells after action potential What triggers the release of parathyroid hormone (PTH)? increasing calcium ion concentration of the blood decreasing sodium ion concentration of the blood decreasing calcium ion concentration of the blood increasing potassium ion concentration of the blood decreasing calcium ion concentration of the blood If you double the total amount of Na ions, but you also double the amount of water they are dissolved in, __________. Na ion concentration will stay the same Na ion concentration will decrease Na ion concentration will increase the concentrations of Na and water will double Na ion concentration will stay the same The pH of the blood primarily depends upon a normal concentration of: magnesium ions. hydrogen ions. Which hormone influences the concentration of hydrogen ions in the filtrate formed by the kidneys? vitamin D3 (calcitonin) parathyroid hormone atrial natriuretic peptide (ANP) aldosterone aldosterone Hypoventilation is the cause of an acid-base imbalance known as: respiratory acidosis. respiratory acidosis. Starvation would cause which of the following acid-base conditions? Also, determine what type of compensation (metabolic or respiratory) there would be. respiratory alkalosis with metabolic compensation metabolic alkalosis with respiratory compensation respiratory acidosis with metabolic compensation metabolic acidosis with respiratory compensation metabolic acidosis with respiratory compensation Diarrhea can lead to which acid/base disturbance? Assuming compensation, would it be a metabolic or respiratory compensation? metabolic acidosis with respiratory compensation respiratory alkalosis with metabolic compensation respiratory acidosis with metabolic compensation metabolic alkalosis with respiratory compensation metabolic acidosis with respiratory compensation Emphysema can lead to which acid/base disturbance? What would be the compensation? respiratory alkalosis; kidneys will retain more H+ and excrete HCO3 − respiratory acidosis; kidneys will retain more HCO3 − and excrete H+ respiratory acidosis; hyperventilation metabolic acidosis; hypoventilation by the lungs respiratory acidosis; kidneys will retain more HCO3 − and excrete H+ Angiotensin-II restores fluid-homeostasis when dehydration occurs due to inadequate fluid intake. Which of the following is NOT an effect of angiotensin-II? stimulation of aldosterone secretion stimulation of antidiuretic hormone (ADH) secretion vasodilation increase sodium ion reabsorption vasodilation The normal hydrogen ion concentration of body fluids is equal to a pH range of about 7.35-7.45. True true Predict what might be found in an arterial blood gases test for a patient who has asthma and has been suffering from pneumonia that has worsened over several days and is obstructing his airways. A patient with pneumonia and asthma is likely to have developed respiratory acidosis that is partially compensated. A patient with pneumonia and asthma is likely to have developed respiratory alkalosis that is partially compensated. A patient with pneumonia and asthma is likely to have developed metabolic acidosis that is partially compensated. A patient with pneumonia and asthma is likely to have developed metabolic alkalosis that is partially compensated. A patient with pneumonia and asthma is likely to have developed respiratory acidosis that is partially compensated. If the Pco2 in the plasma increases, what effect will this have on plasma pH? The pH will increase. The pH will decrease. What effect does an increase in antidiuretic hormone (ADH) have on the volume of extracellular fluid (ECF)? ECF increases when antidiuretic hormone (ADH) is present. ECF increases initially, and then decreases when antidiuretic hormone (ADH) is present. Antidiuretic hormone (ADH) has no effect on ECF. ECF decreases when antidiuretic hormone (ADH) is present ECF increases when antidiuretic hormone (ADH) is present. Increased water volume causes the hydrostatic pressure in plasma to increase and the osmotic pressure to decrease; as a result, water will __________. move from the ICF to the ECF move from the ECF to the ICF move from the interstitial fluid to the plasma not move in any of the listed directions move from the ECF to the ICF Water loss from the body that we do not notice is known as: nonsense water loss. insensible water loss Hyperventilation is the compensation for an acid-base imbalance known as: respiratory acidosis. metabolic acidosis. What leads to metabolic alkalosis? prolonged vomiting and the loss of acidic stomach contents diabetic ketoacidosis in which excess acids are produced visiting a high altitude location prolonged diarrhea in which bicarbonate ions are lost in the feces prolonged vomiting and the loss of acidic stomach contents The most common cause of this electrolyte imbalance is dehydration. hyperkalemia hypernatremia This electrolyte imbalance is normally caused by hyperparathyroidism. hypernatremia hyponatremia hypokalemia hyperkalemia hypercalcemia hypercalcemia This electrolyte imbalance is caused by an abnormal decrease in the plasma sodium ion concentration. hyperkalemia hypernatremia hypercalcemia hypokalemia hyponatremia hyponatremia This electrolyte imbalance can be caused by renal failure, aldosterone insufficiency, cellular destruction from severe burns or trauma, and accidental administration or ingestion of excess potassium salts. hypokalemia hypercalcemia hyponatremia hyperkalemia hypernatremia hyperkalemia This electrolyte imbalance is normally caused by diuretics. hypernatremia hyponatremia hyperkalemia hypokalemia hypercalcemia hypokalemia What would occur if the response to dehydration were regulated by a positive feedback loop rather than a negative feedback loop? After fluid balance was restored, the response would continue, leading to overhydration and other electrolyte and pH imbalances. The fluid balance would not be restored due to electrolytes being secreted continuously, leading to cellular death. The amount of water will be restored; however blood volume and blood pressure will not be restored due to low sodium ion secretion. Secretion of angiotensin-II will continue but ADH and aldosterone will decrease in secretion, leading to electrolyte and pH balance. After fluid balance was restored, the response would continue, leading to overhydration and other electrolyte and pH imbalances. What effect does an increase in ADH have on the volume of extracellular fluid?What effect does an increase in antidiuretic hormone (ADH) have on the volume of extracellular fluid (ECF)? ECF increases when antidiuretic hormone (ADH) is present. Decreased volume and increased concentration of the extracellular fluid (ECF) is defined as: dehydration.
Which hormone promotes the reabsorption of water from the kidneys back into the ECF by osmosis?Water levels in the body are controlled by antidiuretic hormone (ADH), which is produced in the hypothalamus and triggers the reabsorption of water by the kidneys.
When ADH levels rise less water is reabsorbed?When the antidiuretic hormone (ADH) level rises, less water is reabsorbed via the kidneys, the ECH volume decrease, and urine production increases.
Which type of extracellular fluid solution will cause a cell to gain water?If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.
