also, guys, if she is receiving morphine via a patient-controlled pump, it wouldn't allow her to get more than what she should be getting, so I think tolerance would be hard to develop in this scenario + opioids are completely justified in this case

this is actually a UW question (14992) Peripartum cardiomyopathy manifests as a dilated cardiomyopathy, can occur during last month of pregnancy or within 5 months after delivery, pathogenesis poorly understood, but may be related to impaired function of angiogenic growth factors (e.g VEGF) or predisposed by mutations in cardiac structural proteins.

question #15553 in UW explains this one well. Basically, C5 branches innervate Deltoid (abduction) and Infraspinatus(external rotation) and C6 Biceps (forearm flexion), so the right option should be abduction of the upper extremity.

I got it wrong though lol

per UWorld Id 2127:

PCA supplies CN III and IV, thalamus, medial temporal lobe, splenium of the corpus callosum, parahippocampal gyrus, fusiform gyrus, and occipital lobe.

Besides the contralateral hemianopia with macular sparing... a PCA stroke can cause contralateral paresthesias and numbness(involvement of lateral thalamus), dyslexia, visual agnosia (impaired visual recognition of objects) and prosopagnosia (inability to recognize faces)

can we consider the overdose as a suicidal attempt? if so... wouldn't she be considered as without decision-making capacity?

em_goldman  People who are suicidal still have decision-making capacity; it's not equivalent to advanced dementia or other situations where decision making is impaired. Laws vary by state; I know in my state that the maximum time for holding someone against their will is 48 hours unless a court has deemed them incompetent and designated another person as their legal decision maker, including people who are actively suicidal. My understanding of the law as a layperson is that her living will was signed along with people bearing witness to the fact that she was the one who signed it, and it was what she wanted. Ethics aside, it would be almost impossible to prove that she legally initiated a DNR in a state of suicidality that was intense enough to interfere with her decision-making capacity in that moment. +1

poisonivy  this makes sense to me, X cannot be Km!! because if it was Km then line B would be showing a "competitive inhibitor" effect, which cannot be the case since they state that the enzyme activity increases to normal after B6 administration so it favors the reaction instead of decreases it. I got this one wrong of course, too tricky for me! +

hungrybox  Just checking in so I could feel smart about getting this right despite bombing the rest of the test lmao +4  
usmleuser007  can someone please explain the median in this +  
nala_ula  The median can be known by first assembling the numbers in order from least to greater. If it's an uneven number set, the number in the middle is the median (for example: 4, 10, 12, 20, 27 = median is 12 since this is the number in the middle); if the numbers are even then you have to take the two values in the middle, add them up and divide them by 2 [for example: 4, 10, 12, 12, 20, 27 = (12+12)/2 = 12]. Page 261 on FA 2019 explains it as well. Not sure if I explained it well... good luck on the test, people! +  
dubin johnson  Can someone please explain how the mode for Y than X. Not sure how we got the values above. Thanks! +  
dubin johnson  I mean how is the mode for Y greater than mode for x? +1  
sgarzon15  Mode is the one that repeats the most once you list them in order +  
usmile1  Median would be the BP value that the person in the 50th percentile of each group would have. So for group X, to find the 50th percent value, I added 8 + 12 + 32 = 52, which is right above 50, so the median would be 70 mmHg for group X. Doing the same thing for group Y, 2+8+10+20+ 18 = 58; the 50th percentile would fall in group that had a BP of 90 mmHg. which makes the median higher for group Y. hope that isn't wrong, and helps someone! +4  
poisonivy  I did it the same way! not pretty sure if it is the right way to do it, but it gave me the right answer! +

cienfuegos  UW explanation regarding the genes upregulated 1.

poisonivy  The MCV is normal, thalassemias are microcytic anemias, that hint helps to rule out the thalassemias. However, I got it wrong, not sure why it cannot be a homozygous mutation in the ankyrin gene +2
