VPY-0066

QUESTION

Ambient hypoxia occurs due to?

OPTIONS

(A) Low pO2 in atmosphere
(B) High pO2 in atmosphere
(C) Shortage of functional hemoglobin
(D) None of these

ANSWER

(A) Low pO2 in atmosphere

EXPLANATION

Low pO2 in the atmosphere is the correct option because ambient hypoxia results when the inspired partial pressure of oxygen is reduced, such as at high altitude. High atmospheric pO2 would not cause hypoxia, and shortage of functional hemoglobin produces anemic hypoxia rather than ambient hypoxia; therefore “None” is incorrect.
