Question 4 - Found this another forum:
-Statistical significance= Is determined by P value.....and as see the p value is less than .05....hence for sure there is a difference between the two interventions (NOT BY CHANCE ALONE).....If the P Value is greater than .05 u can SAY the difference in the two interventions is due to CHANCE ALONE .....So A is out

-Practical Importance means CLINICAL SIGNIFICANCE not Statistical....and clinical significance MUST ANSWER THE QUESTION ...how effective is the intervention or treatment in the CLINICAL SETTING....And the doctor made the CALL in this case not the researcher....And the way u measure CLINICAL SIGNIFICANCE IS by some of the following methods...EFFECT SIZE ,Number Needed to treat,and Preventive fraction.....

So answer is B (I picked B on mine but did not recall it tell I saw the above).

Question 5 - This has to be B. The reason for this is because if had HIV then either A or C could be correct, and that Toxo hits the frontal lobe not temporal lobe (from what I recall). All his symptoms point to problem in the Wernickes area which is in the temporal lobe. And HSV 1 is #1 causes of temporal encephalitis.

Question 20 - this deals with receptor sparring. Say you have 30 receptors and say Drug X only needs to bind to 15 of those to get the effect (hence the 1st graph on the left that has 0 Drug Y). Now you add Drug Y so some of those recptors taken by Drug Y so not you need more Drug X to get an effect so you see a right shift (since not all 30 are bound to Drug Y so Drug X will bind to free ones there that not taken by Drug Y, but you will need more of X to do it). Then when you give more Y (the last line on the right that has dropped in height) this is when say out of the 30 that 24 are bound. So now Drug X has only 5 to bind to so less effect seen by drug X administation. Hence Answer for this is D not A.

Question 31: Your correct is C. Malassezia like hit where you sweat the most and usually that is the back. And out of all the choices it is the only one that causes white spots on the back. (not sure why this person picked A).

Question 48: For this one I think D. Since Weber syndrome you hit CN III, Corticobulbar (which is the UMN of the face), and Corticospinal tract.
The reason why not D is because this patient has ptosis and a lesion to PICA (Which causes Wallenberg) does not produce ptosis. For choice A the patient should present with inablilty to recongize their own finger (so say you close your eyes you can touch your fingers and tell which one you are touching. In Gerstmann you cannot. Also with Gerstmann you also have dyscalculia and agraphia as well). For choice E not the answer since he has motor problems not just the ptosis.

If anyone can correct me on this one.
