In severe hypoxemia, which may develop due to progressive loss of function?

• A. Loss of consciousness
• B. Weight gain
• C. Loss of judgement
• D. Heightened reflexes

Answer: (C)

Severe hypoxemia deprives brain tissue of oxygen, so brain cells can’t function normally. This cerebral hypoxia tends to show up first as changes in mental status—people become confused, have trouble thinking clearly, and their judgment deteriorates. That decline in judgment reflects the progressive loss of brain function as oxygen delivery remains impaired. If oxygen levels stay low, this deterioration can continue and consciousness may eventually be affected. Weight gain isn’t a direct or typical sign of acute brain hypoxia, and heightened reflexes don’t usually arise as a hallmark feature of this progression. So, impaired judgment best represents the early, progressive brain dysfunction caused by severe hypoxemia.
