A patient with severe dehydration receives gentamicin and later develops rising serum creatinine and granular casts in the urine. Which type of acute kidney injury is most likely?
Correct answer: B. Intrinsic injury caused by damage to renal tubules
- A. Prerenal injury caused by reduced circulating volume
- B. Intrinsic injury caused by damage to renal tubules
- C. Postrenal injury caused by ureteric obstruction
- D. Functional injury caused by temporary urinary retention
Explanation
Gentamicin can injure renal tubular cells, causing intrinsic acute kidney injury and granular casts. Prerenal injury results from reduced renal perfusion, while postrenal injury results from obstruction rather than direct tubular damage.
