A patient showing symptoms of impaired renal function has a battery of tests performed.Results are:
Serum creatinine: 2.0 mg/dL
Urine creatinine: 150 mg/dL
Serum osmolality: 270 mOsm
Urine osmolality: 100 mOsm
24-hour urine volume: 2000 mL
-Based on the information provided,would increasing the patient's intake of fluids alleviate this problem?
A) Yes
B) No

Question

Quizplus · Accepted Answer

The low urine osmolality (100 mOsm) compared to serum osmolality (270 mOsm) and the relatively normal 24-hour urine volume (2000 mL) suggest that the kidneys are able to excrete water but are impaired in their ability to concentrate urine. Increasing fluid intake would not alleviate the underlying renal impairment and could potentially exacerbate symptoms by further diluting the urine.
