  Hey borderline,

Could you explain why #9 is D (mitochondria); I am kinda lost with that question.

For number 28, the reason the answer is gout after occuring post-cholycysectomy is b/c people have to usually restrict their fluid intake before a surgery and that will lead to a concentrated uric acid level in the blood (esp since he has the 2 year history of gout). Remember that large meals and alcohol consumption can precipitate gout attacks as well.

Thanks for posting the answers.

  For the question 9 ;
goljan said in RR that aspirin is a mitochondrial (uncoupling) poison there is even a schema where he shows where it acting .
Seizure I think it is because of ATP depletion (I think the same mecanisme of melas syndrome

  @ sssdewi

for 26 :
nothing other feets actually ARS and pneumenia (lung are clear to auscultation)
respiration rate is very low (8), why you will have this in pulmonary embolism, you will have a shunt and hypoxia but why the respiration rate will decresed if any thing I guess it will increased because of the hypoxia (not sure)
upper airway obstruction you will hear minimal or no respoiration sure but it will be different hearing between the right and the left lung cause of this obstuction.
generally MS patients had congnitif decline and depression so.. I thing suicide attemps feets better .

for 30
do the change then transcript this DNA to mRNA and you will find out a stop codon (in thalassemia that what makes the globin not functional its translation is not completed)

for 42
youre right it is di georgi and it is A.
I just makes a mistake when tapping ... sorry .

  Hi I normally just lurk and dont have much to add cuz im not that good of a student, but i saw that answer 42 in the list is not correct....... i took the mock yesterday online and they give u the questions that u got wrong ..... I did not get #43 wrong otherwise it would have been in the 49 q's i missed .... I chose D respectively .... so it has to be the correct answer... its kinda an easy question so im certain u jus had a typo.... nothing groundbreaking on my part.. neways ive used the help from several pepl... drona maryam... borderline... in this forum.... my contribution... albeit.... microscopic in significance :) .... electron microscopic :)
