Quizplus · Accepted Answer

All three options are normal characteristics of arterial blood. The partial pressure of oxygen (PO₂) in arterial blood is typically around 100 mmHg, the oxyhemoglobin saturation is typically around 97-98%, and the oxygen content is typically around 20 ml O₂ / 100 ml blood. Therefore, the best choice is D, which includes all three options as normal characteristics of arterial blood.
