Narcotic use for acutely painful conditions is both reasonable and important. Short-term use (immediately post-surgical) does not lead to long-term dependence (or so people have thought…). And yes, drugs addicts should also receive narcotics to control pain.

drdoom  prefer “patients with hx of substance abuse” over more conveniently typed but less redemptive “drug addict” +3  
sugaplum  I don't see why switching her to oral pain meds when she is ready would be incorrect. Clearly she is worried about being on the pain meds, I feel making a proclamation that she has a low risk of addiction would be profiling just because she doesn't have a history. The opioid epidemic also affects people who didn't have a previous history of drug abuse. Just a thought, not trying to push any buttons. Maybe I am thinking to hard about this, but I don't see the clear A vs B line for this question. +6  
nbme4unme  @sugaplum I thought the exact same thing as you and chose the acetaminophen answer accordingly. I maintain that I am correct, my score be damned! +2  
sushizuka  I had a similar question on UW and the explanation stated that the correct answer choice was the only one that addressed the patient's concern and answered her question. The rest were just alternative treatments, so they were incorrect. But I too answered with oral pain meds. +  
angelaq11  couldn't agree more with you all. I chose acetaminophen because opioid abuse is NO joke. The crisis is still going strong because of answers like this... +  
houseppary  I ruled out oral acetaminophen because they described in great detail the severity of her injuries, and indicated that she wasn't even fully conscious/aware when she asked this question about opioids. Rather than expose her to more pain, and possibly worsen her long-term pain prognosis, by switching to acetaminophen too early, in this case it makes sense to keep her comfortable because she's very seriously injured and not even fully lucid. It's kind to reassure her in this case. +

Incase anyone else was thinking the same:
I was stuck between this and variant of unknown significance. However, variant of unknown significance is a sequence not a single nucleotide

nbme4unme  Thank you for explaining, I selected the unknown significance answer as well! +

The stem is describing sequelae of posterior inferior cerebellar artery occlusion, resulting in Wallenberg syndrome. Here’s a nice schematic of the affected nuclei and brain stem regions:

... and a 6-minute YouTube video that walks you through it:

nbme4unme  Great video! Very, very solid review of brainstem anatomy. +

Falling on outstretched hand: scaphoid is most common one to be fractured, lunate is most common to be dislocated. Lunate dislocation can cause acute carpal tunnel syndrome.

Think of the mnemonic "Straight Line To Pinky, Here Comes The Thumb" for the bones of the palm, drawing a football shape starting below the thumb MCP joint adjacent to the radius, then moving to your medial wrist, and then back to the thumb.

Scaphoid, lunate, triquetrum, pisiform, hamate, capitate, trapezoid, trapezium. The lunate looks like it's posteriorly dislocated here.

sympathetikey  Yep. I didn't even look at the X-ray. +1  
dr.xx  loonies love lunate +1  
wes79  she landed on her "right hand", but the X-ray is showing a left hand?? +  
wes79  i legit have no idea whats going on in that xray lol +1  
nbme4unme  X-ray confused the hell out of me, I was going to put lunate based on Q stem but ended up putting Pisiform because it looks like that's what's messed up in the photo? Should have ignored the picture haha. +  
nwinkelmann  for @dr.xx, love your mnemonic. I added to it, or at least found an explanation on why it works. "loonies love lunate" and "loonies" are "dislocated" from reality. +1  
doctorevil  She Looks Too Pretty, Try To Catch Her is a mnemonic that works for me. +

Can someone explain why the answer couldn’t be phenylalanine?

donutsnduodenums  The kid has albinism, which is due to decreased tyrosinase activity. If he has a problem metabolizing Phenylalanine, he would be presenting with the PKU sx like intellectual disability, musty body odor, etc., in addition to his fair complexion. +3  
zelderonmorningstar  I see, so if it was PKU he wouldn’t just be presenting for a routine examination. It would be one of those “oh crap what’s wrong with my baby” ones. +2  
wowo  FA2019 p83 +  
nbme4unme  Just a note that UWorld says phenylketonuria patients ALSO have albinism, it's just that the neuro sx and musty order are giveaways. +1
