Despite oxygen therapy, he still has rapid respiration and feels as if he is not getting enough air because even though he is receiving enough oxygen, carbon dioxide and hydrogen ions accumulate in his blood and cause the respiratory rate to continue to increase.
This is the process which involves gaseous exchange in organisms. In humans, we inhale oxygen and exhale carbon dioxide gas.
The presence of the carbon dioxide and hydrogen ions will increase competition with oxygen thereby increasing respiratory rate and makes option D the most appropriate choice.

Despite oxygen therapy, the patient still has rapid respiration and feels as if he is not getting enough air because even though he is receiving enough oxygen, carbon dioxide and hydrogen ions accumulate in his blood and cause the respiratory rate to continue to increase; option D
Pneumonia is a severe inflammation of the lungs caused by a bacterial or viral infection.
The inflammation may occur in both or one of the lungs which which may fill with fluid or pus. This results in thickening of the respiratory membrane.
However, for efficient gaseous exchange, the respiratory membrane should be as thin as possible to allow for easy diffusion of oxygen into the blood and the outward diffusion of carbon dioxide out of the blood
In the case of the the patient who has severe pneumonia, which has thickened the respiratory membrane, there will be impaired gaseous exchange, Therefore, even though he is receiving enough oxygen, carbon dioxide and hydrogen ions accumulate in his blood and cause the respiratory rate to continue to increase.
In conclusion, pneumonia results in impaired gaseous exchange.
