The following questions I had difficulty in understanding:
1.) During the early stages of an asthmatic attack:
Airway resistance decreases
lung compliance increases
the equall pressure point moves towards the mouth
arterial oxygen tension increases
arterial carbon dioxide tension decreases (this was the answer)
2.) A 12 year old girl has been severely anemic (Hg=6 g/dl)for several months. Which of the following is most likely to be decreased during resting conditions?
2-3 DPG
CO
RBC H+ concentration
Mixed venous p02 (answer)
arterial po2
I thought that pO2 does not change (whether its venous or arterial) but that the oxygen content changes. This one really threw me off.
Thanks in advance.
