Normal BUN is 10 to 20 mg/dL.Normal creatinine is 0.6 to 1.2 mg/dL (males)or 0.5 to 1.1 mg/dL (females).Creatinine is more specific for kidney function than is BUN because BUN can be affected by several factors (dehydration,high-protein diet,and others).This client's creatinine is normal,which suggests a non-renal cause of the elevated BUN.A common cause of increased BUN is dehydration,so the nurse should anticipate giving the client more fluids.
