Correct Answer is C
Explanation
A. Increased blood pH: increased pH (alkalosis) shifts the oxyhemoglobin curve left, increasing Hb–O₂ affinity and decreasing O₂ release.
B. Decreased body temperature: lower temperature shifts the curve left (higher affinity), reducing O₂ release.
C. Increased blood PCO₂: higher PCO₂ (and associated lower pH) shifts the curve right (Bohr effect), reducing hemoglobin affinity and increasing O₂ release to tissues.
D. Decreased blood PCO₂: lower PCO₂ shifts the curve left, increasing affinity and decreasing O₂ release.
Correct Answer is A
Explanation
A. 7.3 to 7.5: Correct (closest choice) -normal arterial blood pH is about 7.35–7.45, so 7.3–7.5 best matches the normal range given.
B. 7.6 to 7.8: this is alkalotic and well above normal physiologic range.
C. 6.8 to 7.0: this is severely acidotic and below normal.
D. 7.0 to 7.2: still acidotic and below the normal physiological range.
