What signs and symptoms noted by the nurse are characteristic of renal failure?

A nurse is caring for an 80-year-old patient who was admitted to the hospital with a diagnosis of dehydration. The patient stated he had been vomiting for 2 days and had been unable to take food or fluids. He has been healthy and currently takes only a diuretic for his blood pressure. On physical examination, the nurse notes that the patient’s skin is dry with decreased turgor, oral mucous membranes are dry, heart rate is 100, and blood pressure is 90/60. The patient’ urine is dark amber with a specific gravity of 1.028. His urine output was 30cc/hr for the past 4 hours since admission. 1.
