so , definition of PE = Hypoxemia

So you would see hypoxia and tachypnea = leading to resp alkalosis = low CO2 and increase in Ph.

Well , maybe it depends on the size of the embolus , i mean a really small PE wont cause that big of a problem, while Saddle embolus causes increase in A-a Gradient. Maybe you should keep that in mind when doing the question - If u could show me a question it would be easier to go through it with you.
