Unformatted text preview: therefore it’s more likely to bind protons. c) Venous blood has a higher carbon dioxide capacity than arterial blood. d) Hemoglobin acts as a buffer. e) All of the above are descriptions of the Haldane effect. Type B Multiple Choice: More than one choice may be correct. Select the correct combination of choices according to the pattern below: 1) a, b, and c 2) a and c 3) b and d 4) d 5) All OR none of the above 5) A patient is presented to you who breathes slowly. You believe they are mildly hypoventilating and estimate their alveolar PO2 to be 85 mmHg. If so, what are the possible consequences on their blood gas content compared to an arterial PO2 of 100 mmHg? a) Lower arterial oxygen content. b) Patient is hypoventilating, but not enough to change CO2 content significantly c) Lower arterial CO2 content. d) No major change in arterial O2 content. 6) Which of the following produce the Bohr Effect: a shift of the oxygen‐hemoglobin dissociation curve to the right? a) Lower pH b) Higher temperature c) Higher PCO2 d) Higher hemoglobin concentration Short Answer 7) How does the oxygen‐hemoglobin dissociation curve (see question 5) change when there is a decrease in concentration of hemoglobin in the blood? 8) What are the three forms in which CO2 is transported in the blood? 9) Using the oxygen‐hemoglobin dissociation curve (see question 5), explain how more oxygen will reach tissues with higher oxygen consumption. 10) Explains what occurs between diffusion of CO2 into red blood cells until after HCO3‐ exit from the cells....
