Why couldn't it be inhibition of gastric muscarinic (M1) receptors? Wouldn't that be the most effective overall?

In the question they also don't say whether the antibiotic is administered IV or orally. For an IV dose, F = 100%. For an oral dose, F is typically <100% (FA 2019 p. 233). Based on this, IV maintenance dose would be 25.92 mg/kg/day. However, it is possible that the antibiotic is being given orally and F is closer to 90% (just an example). If this is true, the maintenance dose would be 25.92/0.90 = 28.8. This is obviously based on assumptions, but hopefully another way to explain why the answer is not exactly 25.92.

Also you can extrapolate that the fibers causing his pain have already crossed over because this is a cervical spine section, and the pain he's having is thoracic/lumbar

Here's a picture that really helped:

Why couldn't it be retroperitoneal idiopathic fibrosis?

mcl  Oh! The article I found said that MRSA has been shown to colonize the saliva of bed bugs for up to like 15 days, and that they isolated MRSA from several specimens. Is it just more likely that the patient scratches it in since staph is e v e r y w h e r e ? +6  
chris07  I mean it’s possible. The last review course I took said that it wasn’t associated with anything. It may be, but either way...same answer :) +1  
frijoles  So bedbugs can't transmit HIV. Cool. #whatareyou #anidiotsandwich +8  
anechakfspb  @frijoles - Hey if it makes you feel any better I put HIV too, with my reasoning being that they feed on blood...and HIV is transmitted via bodily fluids. Whoops! +

I was duped; did anybody here get it wrong because they thought about the thyroid ima artery arising from the brachiocephalic trunk? No? Just me? Okay.

peridot  Ooh that is tricky tricky. In the question stem they said they already ligated that one ("a branch of the brachiocephalic trunk") and were wondering what else needs to be ligated in addition to that. Therefore the answer is the superior thyroid artery, which is coming from the external carotid. I don't think I knew any of this when I did the question though, cause I had to google all this just now. +1  
anechakfspb  In the stem they said they ligated a branch of the thyrocervical trunk, not the brachiocephalic. According to Wiki, the thyroid ima artery (which does arise from the brachiocephalic trunk) is only present in about 3-10% of the population. Therefore, while technically this answer could be correct, external carotid is "more correct". Source: +1
