2. Copyright © 2007, Grant Iannelli, DC Course Questions, Problems & Issues

3. Copyright © 2007, Grant Iannelli, DC Fluid & Electrolyte Balance

4. Copyright © 2007, Grant Iannelli, DC What are the three main fluid compartments of the body? Which of these make up extracellular fluid? Fluids

5. Copyright © 2007, Grant Iannelli, DC Water What factors influence the percentage of water in the body?

6. Copyright © 2007, Grant Iannelli, DC Water Gain What are the three sources of water for the body?

7. Copyright © 2007, Grant Iannelli, DC Water Loss List the four organs from which fluid loss occurs.

8. Copyright © 2007, Grant Iannelli, DC Water Loss Why is the body unable to reduce its fluid output to zero no matter how dehydrated it is?

9. Copyright © 2007, Grant Iannelli, DC Electrolytes What is the difference between electrolytes and nonelectrolytes?

10. Copyright © 2007, Grant Iannelli, DC Electrolytes Name the three most important negative ions. Name three important positive ions.

11. Copyright © 2007, Grant Iannelli, DC How does aldosterone influence water movement between the kidney tubules and the blood? Aldosterone

13. Water Movement What is the role of capillary blood pressure in water movement between the plasma and interstitial fluid?

14. Copyright © 2007, Grant Iannelli, DC Water Movement What is the role of plasma proteins in water movement between the plasma and interstitial fluid?

15. Copyright © 2007, Grant Iannelli, DC Urine Regulation Where is each made and what is the specific effect each has on urine volume? Name the three hormones that regulate urine volume.

16. Copyright © 2007, Grant Iannelli, DC

17. Describe the common fluid imbalances. Dehydration Overhydration Edema Fluid Disturbances

18. Copyright © 2007, Grant Iannelli, DC Acid-Base Equilibrium

19. Copyright © 2007, Grant Iannelli, DC Acids and Bases What is an acid? A base?

20. Copyright © 2007, Grant Iannelli, DC What is the relationship between pH and the relative concentration of hydrogen and hydroxide ions in solution? The pH Scale

21. Copyright © 2007, Grant Iannelli, DC What is the chemical reaction that converts carbon dioxide and water to carbonic acid? Acid-Base Chemistry What enzyme catalyzes this reaction?

22. Copyright © 2007, Grant Iannelli, DC Acid-Base Chemistry What is a buffer?

23. Copyright © 2007, Grant Iannelli, DC

24. Acid-Base Chemistry How does a buffer pair react if more hydrogen ions are added to the blood?

25. Copyright © 2007, Grant Iannelli, DC Acid-Base Chemistry How does a buffer pair react if more hydroxide ions are added to the blood?

26. Copyright © 2007, Grant Iannelli, DC Acid-Base Chemistry What changes occur in the blood as a result of buffering fixed acids?

27. Copyright © 2007, Grant Iannelli, DC Acid-Base Balance Explain the respiratory mechanism of pH control.

28. Copyright © 2007, Grant Iannelli, DC Renal pH Control Explain how the kidney uses NaH2PO4 to remove hydrogen ions from the blood.

29. Copyright © 2007, Grant Iannelli, DC Disturbances Define acidosis and alkalosis.

30. Copyright © 2007, Grant Iannelli, DC Disturbances Explain disturbances of the buffer pair.

31. Copyright © 2007, Grant Iannelli, DC Case Study: Justin Peaks A mountain climber, Justin Peaks, spent several days camped at a very high altitude on a mountain. He noticed that he was breathing faster than normal and that he began to feel nervous, excitable, and his muscles were hyperactive. Suggest a reason for his symptoms.

32. Copyright © 2007, Grant Iannelli, DC Case Study: Justin Peaks Justin felt ill and vomited several times. How would this affect his alkalosis?

33. Copyright © 2007, Grant Iannelli, DC Case Study: Justin Peaks Because Justin didn’t feel well, he took several antacid tablets, which contained sodium bicarbonate. Was this a good idea? How would this affect his alkalosis?

34. Copyright © 2007, Grant Iannelli, DC Case Study: Justin Peaks How would his body work to control his alkalosis and maintain homeostasis of the pH of his body fluids?
