a client develops acute renal failure (arf) after receiving iv therapy with a nephrotoxic antibiotic. because the client's 24-hour urine output totals 240 ml, the nurse suspects that the client is at risk for:

Nephrotoxicity is defined as a rapid decline in kidney function caused by the toxic effects of drugs and substances. There are numerous types, and some medications can have a negative impact on renal function.

The serum potassium level rises as urine output decreases; if it rises sufficiently, hyperkalemia may occur, potentially triggering a cardiac arrhythmia. Paresthesia is not caused by hyperkalemia (sensations of numbness and tingling). Dehydration does not occur during the oliguric phase of ARF, but it does occur during the diuretic phase. Pruritus in an ARF patient is caused by increased phosphates and is not associated with hyperkalemia.
