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

Answer and Explanation

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.

Correct Answer is C

Explanation

Choice A reason: In the oliguric phase of acute kidney injury, the creatinine level is expected to increase, not decrease, due to impaired kidney function and decreased filtration.

Choice B reason: The GFR is expected to decrease in acute kidney injury, not increase, as the kidneys' ability to filter

blood is compromised.

Choice C reason: Hyperkalemia, or high potassium levels in the blood, is a common finding in the oliguric phase of acute kidney injury due to decreased excretion of potassium by the kidneys.

Choice D reason: Hypomagnesemia, or low magnesium levels, is not typically associated with the oliguric phase of acute kidney injury. Instead, hypermagnesemia may occur due to decreased excretion of magnesium.

A. "I will enjoy eating cantaloupe for my morning snack." B. "I can easily add baked potatoes to my diet." C. "Eating yogurt will be a new experience." D. "Adding pecans will be a change I can readily make."

Correct Answer is B

Explanation

The correct answer is choice D. “Adding pecans will be a change I can readily make.”

Choice A rationale: Cantaloupe is a fruit that is high in potassium. For individuals with acute kidney injury, it is important to limit potassium intake because their kidneys may not be able to effectively eliminate excess potassium from the bloodstream. Therefore, choosing cantaloupe for a snack would not indicate an understanding of the dietary restrictions necessary for managing potassium levels.

Choice B rationale: Baked potatoes are another food item that contains a significant amount of potassium. Similar to cantaloupe, consuming baked potatoes would not be advisable for someone who needs to control their potassium intake due to impaired kidney function. The client’s statement about adding baked potatoes to their diet does not reflect an understanding of the teaching provided.

Choice C rationale: Yogurt, while a nutritious food, also contains a considerable amount of potassium. For a client with acute kidney injury, eating yogurt could contribute to an undesirable increase in potassium levels, which the damaged kidneys may not be able to process efficiently. Thus, the client’s interest in eating yogurt does not demonstrate a correct understanding of the dietary guidelines given their condition.

Choice D rationale: Pecans are a low-potassium food option, making them a suitable choice for someone with acute kidney injury who needs to monitor and limit their potassium intake. The client’s willingness to add pecans to their diet indicates a proper understanding of the dietary changes necessary to manage their condition effectively. Therefore, this choice is the correct answer.
