yes 3.
gold standard test for diagnosis is pulm angiog ( this is invasive so it is not the first test to be performed)
V/Q ratio is second best but the one we are more likely to perform first. if it dx PE, no need for angio. in the post op pt, do spiral CT cos v/q are usu abN in these pts.

the answer depends on the question (clinical setting), but as it is posted here, the answer is still V/Q scan...
maybe if you post the question completely, the answer can change...

If q simply states next step, then CXR and ABG´s is right. If q says "best", "most accurate", "next step in diagnosis" "most appropriate" then ur answer will change.

In this case "most appropriate in patient MANAGEMENT" is key. As you are taking a stepwise approach to an entire clinical situation not only a diagnosis. This type of Q is like ur actual ER rotation management. What would u get first for real?

I agree with 6.
But actualyquestion is not complete-how did we suspect? What do we have? On auscultation we may have normal sound. PE can mimic many heart disease, so we would probably see on ECG S1 Q3 T3 or only tachycardia.
After that we would probably do chest X ray and arterial blood gases.
Chest X ray may be normal in almost 10 %.
So, the next step is V/Q if O2 is low and D dimer.
Angio is gold standard , but in real too invasive and often not necessery, since patients usually get better after anticoagulant treatment had started.
