Question 1 of 5
A nurse is reviewing the medical records of a client who has heart failure. The nurse should identify which of the following laboratory results as an indication that the client has fluid volume excess.
Correct Answer: D
Rationale: A urine specific gravity of 1.015 is within the normal range (1.005-1.030). While fluid volume excess may lead to a lower specific gravity due to urine dilution, this value does not indicate fluid overload and is considered normal. A hematocrit level of 42% is within the normal range for adults (men: 38-50%, women: 35-45%). Hematocrit levels tend to decrease in fluid volume excess due to hemodilution, but this value does not suggest fluid overload. A urine pH of 6.5 is within the normal range (4.5-8.0). Urine pH reflects the acid-base balance rather than fluid status and is not a reliable indicator of fluid volume excess. A BUN level of 5 mg/dL is below the normal range (10-20 mg/dL). In fluid volume excess, the dilution of blood plasma can lead to decreased BUN levels. This low BUN value, in conjunction with clinical symptoms, supports the diagnosis of fluid volume excess.
