NURSING MANAGEMENT ARF/CRF questions and answers with solutions 2025

A patient admitted with severe dehydration has a urine output of 380 ml over the next 24 hours and elevated blood urea nitrogen (BUN) and creatinine levels. A finding that the nurse would expect when reviewing the patient's urinalysis is a. proteinuria b. bacteriuria specific gravity. ar casts. - ANSWER Correct Answer: C Rationale: The patient's renal failure has been caused by the prerenal problem of hypovolemia. Prerenal oliguria is characterized by the ability of the kidneys to concentrate urine, resulting in a high urine specific gravity. The urinalysis in intrarenal failure would show proteins and tubular casts. Bacteriuria would be typical of a urinary tract infection (UTI), not renal failure. 2. A patient with acute renal failure (ARF) has an arterial blood pH of 7.30. The nurse will assess the patient for a. tachycardia. b. rapid respirations. c. poor skin turgor. d. vasodilation. - ANSWER Correct Answer: B Rationale: Patients with metabolic acidosis caused by ARF may have Kussmaul respirations as the lungs try to regulate carbon dioxide. Tachycardia and vasodilation are not associated with metabolic acidosis. Because the patient is likely to have fluid retention, poor skin turgor would not be a finding in ARF. 3. A patient with severe heart failure develops elevated BUN and creatinine levels. The nurse plans care for the patient based on the knowledge that collaborative care of the patient will be directed toward the goal of a. preventing hypertension. b. diluting nephrotoxic substances. c. replacing fluid volume. d. maintaining cardiac outpu
