A client with a 16-year history of diabetes mellitus is having renal function tests because of recent fatigue, weakness, elevated blood urea nitrogen, and serum creatinine levels. Which finding should the nurse conclude as an early symptom of renal insufficiency?
Stomatitis and Diarrhea
Dyspnea and Anuria
Confusion and Vomiting
Nocturia and Oliguria
The Correct Answer is D
Choice A rationale: These are symptoms of advance renal failure. Stomatitis and diarrhea are signs of uremia, which is the accumulation of waste products in the blood.
Choice B rationale: Dyspnea and anuria are signs of fluid overload and kidney shutdown and indicate advanced renal failure.
Choice C rationale: Confusion and vomiting are signs of acidosis and electrolyte disturbances and occur in advanced stages of renal failure.
Choice D rationale: One of the early symptoms of renal insufficiency is nocturia, which is the need to urinate frequently at night. This occurs because the kidneys are unable to concentrate urine during the day and produce more urine at night. Another early symptom is oliguria, which is the production of less than 400 mL of urine per day. This occurs because the kidneys are unable to excrete enough urine to maintain fluid balance.

Choice C rationale: Horner's syndrome is caused by damage to the sympathetic nerve fibers in the neck or chest, resulting in drooping eyelid, constricted pupil, and lack of sweating on one side of the face.
Choice D rationale: Brown-Séquard syndrome is caused by hemisection of the spinal cord, resulting in ipsilateral loss of motor function and proprioception and contralateral loss of pain and temperature sensation below the level of the lesion.
