A nurse is caring for a client who has lung cancer and is receiving combination chemotherapy with cisplatin and etoposide. Which of the following interventions should the nurse implement to prevent nephrotoxicity from cisplatin?
Administering mannitol as prescribed before cisplatin infusion can prevent nephrotoxicity by increasing urine output and reducing the concentration of cisplatin in the kidney. Mannitol is an osmotic diuretic that draws water from the extracellular space into the tubular lumen, thereby increasing urine volume and flow rate. Mannitol can also scavenge free radicals and reduce oxidative stress induced by cisplatin⁴.
Monitoring serum creatinine and blood urea nitrogen levels daily can prevent nephrotoxicity by detecting early signs of renal impairment and adjusting the dose of cisplatin accordingly. Serum creatinine and blood urea nitrogen are markers of kidney function that reflect the glomerular filtration rate (GFR). An increase in these levels indicates a decrease in GFR and a loss of kidney function. The dose of cisplatin should be reduced or withheld if serum creatinine or blood urea nitrogen levels rise above a certain threshold⁴.
Encouraging fluid intake of at least 3 L per day during treatment can prevent nephrotoxicity by maintaining adequate hydration and preventing dehydration. Hydration is essential for preventing cisplatininduced renal toxicity, as it dilutes the concentration of cisplatin in the kidney and enhances its elimination. Dehydration can increase the risk of nephrotoxicity by reducing renal blood flow and causing tubular obstruction by uric acid crystals. Fluid intake can be oral or intravenous, depending on the patient's condition⁴.
These are all interventions that can prevent nephrotoxicity from cisplatin, which is a potent and valuable chemotherapy drug that can cause kidney damage or failure. Nephrotoxicity is one of the most serious and doselimiting adverse effects of cisplatin, which can affect up to 30% of patients. Nephrotoxicity is caused by the accumulation of cisplatin in the renal tubular cells, leading to cell injury, inflammation, and ischemia³.
