A.
Intrarenal
B.
Postrenal
C.

ANS: A
Gentamycin is one of the aminoglycoside antibiotics, which are known to be nephrotoxic, leading to intrarenal kidney injury. Prerenal kidney injury is due to decreased perfusion. Postrenal kidney injury is obstructive in nature. Strep infections can cause damage to body systems, but there is no indication this child had a strep infection. Gentamycin is directly related to an intrarenal injury.
