A nurse is caring for a 68-kg (150-lb) client who has dehydration. Which of the following manifestations is an indication of effective treatment?
Urine specific gravity 1.005 to 1.030
Decreased pulse pressure
Lightheadedness
Urine output 75 mL in 1 hr
The Correct Answer is D
The correct answer is D. Urine output 75 mL in 1 hr.
Adequate urine output (at least 30 mL/hr) indicates effective hydration, showing that the kidneys are functioning properly and fluid balance is improving. A urine output of 75 mL in 1 hour suggests sufficient fluid replacement.
Here’s why the other options are incorrect:
-
A. Urine specific gravity 1.005 to 1.030 – This range covers both normal and abnormal values. In dehydration, urine specific gravity is usually high (>1.030) due to concentrated urine. Effective treatment should lead to lower urine specific gravity, but the full range does not confirm improvement.
-
B. Decreased pulse pressure – Pulse pressure is the difference between systolic and diastolic blood pressure. Dehydration typically causes a narrowed pulse pressure, so improvement should lead to a normal or increased pulse pressure rather than a decrease.
-
C. Lightheadedness – Dizziness and lightheadedness are signs of dehydration-related hypotension. Effective hydration should resolve these symptoms, not maintain them.

Choice C reason: Bananas are known to be high in potassium and should be limited or avoided in clients with chronic kidney disease.
Choice D reason: Tomatoes and tomato products are high in potassium and should be avoided to maintain safe
potassium levels.
Choice E reason: Green beans are not considered high in potassium and do not typically need to be avoided by clients with chronic kidney disease.

Choice C reason: Long-term use of ibuprofen can affect kidney function but is not a direct cause of pyelonephritis.
Choice D reason: Genetic diseases can affect kidney health, but there is no common genetic disease that directly causes pyelonephritis.
