. Why do you think a weak acid/weak base chemical buffer system is effective at regulating blood pH?
General Blood Urine BP: 95/58 pH: 7.1 Odor: "fruity acetone" HR: 110 bpm Glucose: 345 mg/dl pH: 4.3 Ketone bodies: 22 mg/dl Glucose: Strongly positive Blood alcohol: 110 mg/dl 4. Explain how the pH of Mr. Bouchard's blood and urine is related to the ketone bodies measured in each of these fluids. 5. Provide a possible "alternative" explanation for Mr. Bouchard's erratic behavior and high blood alcohol concentration. Think outside the box. 6. What metabolic disease do you suspect Mr. Bouchard suffers from?
Metabolic alkalosis refers to a process whereupon decreased hydrogen ion, or increased bicarbonate, concentrations occur in the body, and the blood pH becomes too basic. Answer the following questions: How does the body regain its acid-base equilibria/balance? What happens when that balance does not happen? Will a buffer system still work under these conditions?
At a pH of 7.40, the carbonic acid ratio is a.35:1 b. 4:1 C. 20:1 d. 3:1
Case Study: Bob is a 64-year-old male admitted to the emergency room for asthma. His laboratory results are as follows: pH 7.31, pCO2 higher than normal, and total HCO3– also higher than normal. Classify his acid-basebalance as acidosis or alkalosis, and as metabolic or respiratory. Is there evidence of compensation? Propose the mechanism by which asthma contributed to the lab results seen.
