A nurse is caring for a client with diabetes who is scheduled for a radiographic study requiring contrast. Which should the nurse expect the health care provider to prescribe?

ExplanationA. Acetylcysteine (Acetadote) is an antioxidant that scavenges oxygen free radicals, which are released when contrast medium causes cell death to renal tubular tissue; it also induces slight vasodilation. B. Contrast that is renal friendly does not exist. C. Mannitol (Osmitrol) is not necessary. Saline alone provides better protection of the kidneys from contrast-induced nephropathy. D. Hydration with saline, not dextrose and water, affords some protection from kidney damage caused by contrast media; dextrose will increase the glucose level in an individual with diabetes and thus is contraindicated.
