Q13  C or D is incorrect. Its just D

If you have a pacemaker you can't undergo an MRI Scan due to the magnetic shit

[samikk]

according to you i got about 3 or 4 wrong is taht good or bad???

[sophx]

but u also cant undergo a fmri if u have a pacemaker can u ?

My guess it that they'll have to accept both due to the wording of the question. But I don't know.

Whoops I meant B or D, not C or D

[jiaptial]

crap. i missed the bit about function.

[jess3254]

but u also cant undergo a fmri if u have a pacemaker can u ?

Yeah. That's why there were no correct answers. So my guess is that they'll have to accept both PET and fMRI, because they specified that it had to be the 'function' of the brain.

but u also cant undergo a fmri if u have a pacemaker can u ?

yeah i think your right. I said 'A' because you dont always need an injection for CT and if you do its only die.

Yeah, but the question specified he needs information about 'brain function'. CT only shows anatomy.

Don't worry yet! These are only suggested according to me. There may be a couple of correct responses to some questions (usually happens every year). Also double check over the exam and let me know if you disagree with any of the suggested answers.

For question 39 could it possibly be D because there is some very small muscle movement during REM sleep?

[fossil]

does sleep talking occur in both rem and nrem? i always thought it only happend in stage 3/4 nrem.

[Ripe.Banana]

question 43 is C not D.

Sleep talking can only occur during stages 3 and 4 of NREM and never occurs in REM sleep

[fossil]

For question 39 could it possibly be D because there is some very small muscle movement during REM sleep?

yeah, what about the movement of muscles around the eyes that an EOG measures?

Question 13 should be A.

CT uses X-rays.

It can't be PET because of injections, it can't be MRI due to MAGNETIC Resonance Imaging, and it can't be fMRI for the same reason, as well as the fact that injections are used in fMRI too.


Question 17 should be D. The patient MUST be conscious for it to be effective, so therefore mild electrical corrent is MOST correct.

Apart from that it is all good.

The only mark I dropped was on the camouflage question, I misread it and chose A instead of C.

Sigh.
