Aminoglycosides are nephrotoxic; nephrotoxic chemicals/drugs cause acute tubular necrosis (ATN), characterized by damage to the PCT. ATN causes the formation of brown, muddy, granular casts in the urine. The fact that this patient is a quadriplegic might be suggesting that they have a lower volume of distribution for the drug (and therefore higher blood concentrations).
mtkilimanjaroI would also like to add ATN is nephrotoxic ischemia and the two places in the tubule that are susceptible are the PCT (proximal straight part) and the thick ascending limb. The TAL is not labeled as a choice so that is why it has to be B (and why B is a little further down from the convoluted part)+4
mtkilimanjaroActually aminoglycosides might only affect the PCT idk :( +2
peridoton p. 591 of FA 2019, it talks about ATN. The two types are 1. ischemic - affects PCT and thick ascending limb because those two areas use ATP the most (think of all the ion pumps) and 2. nephrotoxic - PCT only (I think of it as that's the first part, so it's most exposed to toxins). Aminoglycosides fall under scenario 2.+3
