Question

Compare the changes in percent hemoglobin saturation that would occur in the two following situations: I. The blood PO2 drops from 100 mm Hg to 80 mm Hg. II. The blood PO2 drops from 40 mm Hg to 20 mm Hg. Select one: a. In both situations, the percent hemoglobin saturation would decrease by 20%. b. There would be very little reduction in percent hemoglobin saturation in situation I but a large reduction in situation II. c. There would be a large reduction in percent hemoglobin saturation in situation I but very little reduction in situation II. d. In both situations, the percent hemoglobin saturation would increase.

Answer 1

Compare the changes in percent hemoglobin saturation that would occur in the two following situations: I. The blood PO2 drops from 100 mm Hg to 80 mm Hg. II. The blood PO2 drops from 40 mm Hg to 20 mm Hg. Select one:

a. In both situations, the percent hemoglobin saturation would decrease by 20%, option (a) is not correct answer because in 1 sutiation percentage decrese is 20% and in 2nd case is 50%.

. b. There would be very little reduction in percent hemoglobin saturation in situation I but a large reduction in situation II. option (b) is correct answer. in first little reduction occur about 20% and in second case large reduction about 50%

c. There would be a large reduction in percent hemoglobin saturation in situation I but very little reduction in situation II. option (c) is not correct option because only 20% decrease in 1st case and 50% in second case.

d. In both situations, the percent hemoglobin saturation would increase. option (d) is not correct becasue in both hemoglobin % is decreases.

FOR ANY DOUBT POST A QUESTION, IT WILL BE HIGHLT APPRECIATED.
