PhysioEx Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1 In cases of acidosis, the pH of the blood is You correctly answered: less than 7.35. 2 Carbon dioxide and water form You correctly answered: carbonic acid (a weak acid). 3 Which of the following is true of respiratory acidosis? You correctly answered: The amount of carbon dioxide in the blood is greater than normal. 4 Rebreathing You correctly answered: is exemplified by breathing into a paper bag. Stop & Think Question 1 Which of the following can cause respiratory acidosis? You correctly answered: airway obstruction. Experiment Data Condition Normal Min. P CO2 (mm Hg) 40 Rebreathing 40 Max. P CO2 (mm Hg) 40 53.95 Min. pH 7.39 7.24 Max. pH 7.39 7.42 Normal Breathing Rebreathing Post-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1 Rebreathing simulates You correctly answered: hypoventilation and respiratory acidosis. 2 Hypoventilation results in You correctly answered: an accumulation of carbon dioxide in the blood. The renal system can compensate for respiratory acidosis by You correctly answered: excreting H and +retaining bicarbonate ion. 4 Respiratory acidosis can be caused by all of the following except You correctly answered: an anxiety attack. Review Sheet Results 1 Describe what happened to the pH and the carbon dioxide levels during rebreathing. How well did the results compare with your prediction? Your answer: Min Pco2 stayed the same and the Min pH decreased Max Pco2 and Max pH increased. 2 Describe some possible causes of respiratory acidosis. Your answer: airway obstruction, lung disease, drug overdose. 3 Explain how the renal system would compensate for respiratory acidosis. Your answer: the renal system would compensate for respiratory acidosis by excreting H+ and retaining bicarbonate (HCO3).
