Question 16: Which of the following statements about case studies is the most correct?
A. Case studies can provide ideas for further research.
D. Results from a case study are able to be generalised in most situations.

I put D

(I only got 2,3 or 4 wrong and its like the questions everyone is arguing about so i'm kinda happy..)

It's not D, because case studies cannot be usually generalised to others.

Put they are (aren't they), that's what they are used for..
Indepth descriptions of an event, and researchers read over, and yeah it can be generalized to others ? its just heaps time confusing...

But I do think A is correct.. I had that first, then i thought just D was more correct..

Remember, whilst Phineas Gage may have had a pole stuck through his brain, it doesn't mean that if I got a pole stuck through my head, my personality would completely change.

Another way of thinking about this is consider me having a cold. After eating my faeces, I start feeling better. Therefore faeces can be used to treat colds.

Obviously, that's absurd. Just because I seemed to get better after being administered faeces, doesn't mean other would.

That is a very, very bizarre analogy...But we don't need to know any of this anymore because unit 3 IS OVER

the answer for 13 is B because PET scan patients can take the radiactivce substances orally in a capsule therefore avoiding invasive injections

Read the Grivas textbook again page 115

the question says Zoe, an elderly woman with a pacemaker needs to have a brain scan to investigate a possible brain abnormality- this is something that a CT can pick up.
My teacher told me that it's rate that the glucose is inserted orally and 99% of the time, it involves an invasive injection.

besides u need an injection to do CT scans

The CT scans require a noninvasive injection though-- just a contrast solution. But it only shows structure so it can't be CT.

sleep talking can occur during REM and NREM. its coherent in REM and incoherent in NREM.

for question 10, wouldnt it be D? because an increase in blood pressure is bad, not good. and during shock your bodys ability to cope falls below normal?

[wonkachic]

i got a few wrong.. like 4. if i do good in short answers and all my sacs are A+ .... can i still have a chance of getting A?
thanks guys.

Yes of course! We don't know how many marks you can afford to lose in the exam for this year for an A+, but some years you have been able to lose 8-11 marks and still get an A+.

My opinion is that this exam was more difficult than 2008, so I think the requirement for an A+ will be lower than last year's. But that's just a prediction, i could be completely wrong.

*BOO*

When someone surprises you like that, your blood pressure goes up because of the cortisol release right?

An increase of blood pressure isn't necessarily a bad thing, unless it is long term (so say getting to late-resistance, exhaustion stage). Whereas this is different. At shock your body initially isn't able to cope but there is a rapid build up of  the mechanisms to be able to fight this virus. High blood pressure and High body temperature are known to be some of these mechanisms.

[claireburum]

so the answer is D then???

[Glockmeister]

Nit it's C

During shock, those mechanisms I described earlier aren't activated. It is only when at counter-shock where the blood pressure and body temperature increase.

[jess3254]

so the answer is D then???

No, the body initially responds by dropping blood pressure in the 'shock' phase of alarm reaction. Then the body goes into 'counter shock', activates the sympathetic nervous system and causes an increase in blood pressure and body temperature

Just thought I would add about Question 13.
In the book that my school uses, there is absolutely no mention of the Radioactive Glucose being administered orally, only mentions injection.
Surely VCAA will just ignore this question.

I put D my reasoning behind it is quite weird
I noticed the questioned mentioned the fact that she has a pacemaker.
BUT, in the last part of the question all it mentions is without "invasive injections", so yeah.

[d0minicz]

i just put PET because thres absolutely no chance that the patient can have an MRI/fMRI, which is preferable over the doctor's preferences
