Realizing that chemotherapy can result in renal damage, the nurse should:

Rationale: A. Routine use of diuretics is not a standard preventative measure for chemotherapy-related renal damage. Diuretics can sometimes lead to fluid and electrolyte imbalances if used inappropriately and do not directly protect the kidneys from chemotherapy toxicity. B. Monitoring kidney function through lab tests (e.g., serum creatinine, BUN, electrolytes) and urine output is essential because many chemotherapy agents (like cisplatin or methotrexate) are nephrotoxic. Early detection of renal impairment allows timely interventions such as dose adjustments, hydration, or medications to prevent further damage. C. Caffeinated beverages do not provide renal protection and may increase dehydration or irritate the bladder, which can worsen kidney function. Proper hydration with water or prescribed fluids is recommended instead. D. Giving additional nephrotoxic drugs (like certain antibiotics or NSAIDs) while the client is receiving chemotherapy increases the risk of kidney injury and should be avoided unless specifically indicated and closely monitored.
