NBME 12 SECTION 01

1 B
2 A
3 I do not know (B is wrong for sure), may be E because the doctor should be sure that his patient want to quite before giving him advices ?? who knows??
4 D (selectin loose binding on endothelial cells.. See FA pathology section)
5 F (riketssia Rx tetracycline)
6 E
7 B (horner syndrome)
8 B (avascular necrosis--medial femoral circumflex = memorisation)
9 C (why not anticholinergic?? cause vagus stimulate G cell by GRP= gastrin releasing petptide, not ACTh see FA gastroenterlogy section).
10 D spherocytosis. not pale centre in RBC+ unconjugated bilirubin
11 B (vinblastin+ vincristine + paclitaxel work on microtubules first two decreasepolymerisation , taxols does not let microtubules break down so the cell is fixed in metaphase I think :) )
12 B
13 B (avoid eye contact = kind of autist but normal inteligence, asperger is kind of autism )
14 F not sure( NNT = 1 / (Control Event Rate) - (Experimental Event Rate) -->
1/(0.023-0,013)
15 E
16 A
17 A
18 D (cigarette smokes in winter so i guess windows are close CO poisening)
19 A parietal cell destruction ---> intrinsic factor low ---> megaloblastic anemia.
20 A (not sure , D is wrong for sure)
21 A (klinfelter)
22 E
23 A (it"s an antagonist of acethylcholine uses in asthma)
24 E
25 A leuprilide continous stimulation of gonad lead to decrease secretion of sexe hormone (androgene is our cible in this case)
26 C
27 E (first see PH, is decreased means acidosis, she is hyperventilation means respiration started the compensatory process, after 2 days I think, the kidney will start also puting HCO3 in the blood and sectreting with the urine H+ .. NH4CL is a titrable acide means like a boat to put H+ in to send out of the body)
28 mystery question for me I could not even know the diagnosis (A is wrong) may be C just because intestine are involved :), no rational reason , please hepl to figure out the diagnosis.
29 C 2 isoenzyme means the work on the same familly of molecules . enzyme 1 is faster (300) than enzyme 2 (30) . why ? becasue the affinity of enzyme 1 is greater than enzyme 2. mmeans you need less amount of enzyme 1 then enzyme 2 (Km)
30 C
31 A
32 F (it is about apoptosis BCL2/Akt. you can google it but I am not sure)
33 B almost sure (external validity means can you generate the result to all patients in this study the reaaly choose a very representative population with inssurance and without, different gendre different socioeconomic status. so you ac apply the result of the study on all type of patients).
34 B (infliximab is MAB for TNF)
35 C (I think in spontaneus pneumothorax you will not hear respiration at all and why will be wheezes?)
36 E (transpantation ---> CMV= virus = T lymphocytes)
37 A
38 may be D (C is wrong) 3 years 20 words: there is a prob here. MRI is expensive to start with I think :-)
39 A
40 D angiotensine converting enzyme is synthesises in the lung (I think the buzz word here is directly mediated may be...)
41 D
42 E (it is not about humerus or shoulder:so B or E she did not fall just grabbed hand and no edema)
43 D not sure ( portal hypertention )
44 C (nitroglycerine dilate veins ans arteriol via NO)
45 C alzheimer
46 C
47 E (no change after desmopressin )
48 F (weekness = motor, atrophy = lower MN . left =left decussation of pyramid al tract is in the medullae)
49 D (no mitosis no necrosis+ most common GYN tumor )
50 F (steroid liposoluble acces to the cell and the nucleous).

NBME 12 SECTION 02

1 E Normal renal architecture (tubular re-epithelization after ATN)
2 B E-cadherin
3 A Bromocriptin (increase Dopamine=Prolactin inhibitor)

  section 1, question 43:
the answer is D) short gastric vein because of portal hypertension.
the arrow is pointing to the portal vein, and the only one of those veins that drain to the portal vein is short gastric (via splenic vein)

  This is funny, does larva think that the test #s are in the same order on his exam than everyone elses? This ABACCDAEBBEAC garbage is pretty much worthless if you don't have the actual questions.
