Question 1 of 5
A nurse is caring for a client who has acute dehydration and is receiving IV fluids. Which of the following laboratory values indicates to the nurse that the current treatment regimen is effective?
Correct Answer: C
Rationale: The correct answer is C: Urine specific gravity 1.020. This value indicates the concentration of solutes in the urine, with a higher value indicating more concentrated urine, which is expected in dehydration. If the urine specific gravity is closer to normal range (1.005-1.030), it suggests that the kidneys are conserving water properly and the IV fluids are effective.
Incorrect choices:
A: Sodium 165 mEq/L - High sodium levels indicate hypernatremia, not necessarily dehydration.
B: Hematocrit 62.5 - High hematocrit levels indicate hemoconcentration, which can occur in dehydration, but it's not as specific as urine specific gravity.
D: Potassium 3.2 mEq/L - Low potassium levels can be seen in dehydration, but it's not the most specific indicator of treatment effectiveness.
E: Potassium 3.2 mEq/L - Repeated choice.
In summary, urine specific gravity is the
