In a healthy person at sea level, the oxygen saturation of haemoglobin in blood returning to the lungs is approximately:Question 44Answera.98%b.75%c.50%d.25%e.2%

) In arterial blood with a PO2 of 60 mmHg, which of the following situations will resultin the lowest blood oxygen saturation?a) decreased DPG with normal body temperature and blood pHb) increased body temperature, acidosis, and increased DPGc) decreased body temperature, alkalosis, and increased DPGd) normal body temperature with alkalosise) increased body temperature with alkalosis

5) Which of the following will cause the largest increase in systemic arterial oxygensaturation in the blood?a) an increase in red cell concentration (hematocrit) of 20%b) breathing 100% O2 in a healthy subject at sea levelc) an increase in arterial PO2 from 40 to 60 mmHgd) hyperventilation in a healthy subject at sea levele) breathing a gas with 5% CO2, 21% O2, and 74% N2 at sea level
