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 BUN,because BUN can be affected by several factors (dehydration,high-protein diet,and catabolism).This client's creatinine is normal,which suggests a non-renal cause for the elevated BUN.A common cause of increased BUN is dehydration,so the nurse should anticipate giving the client more fluids,not placing the client on fluid restrictions.Hemodialysis is not an appropriate treatment for dehydration.The lab results do not indicate an infection; therefore,a urine culture and sensitivity is not appropriate.
