A nurse is assessing a client who has heart failure and is taking furosemide. Which of the following findings should indicate to the nurse that the client is experiencing fluid volume deficit?

A. Elevated hematocrit level can indicate hemoconcentration due to fluid volume deficit. When there is a decrease in plasma volume, the concentration of red blood cells increases, leading to a higher hematocrit level. B. Weight gain is typically associated with fluid retention, not fluid volume deficit. In heart failure, weight gain can indicate worsening fluid overload. C. Shortness of breath is a common symptom of fluid overload in heart failure, not fluid volume deficit. It occurs due to pulmonary congestion and edema. D. Distended neck veins are a sign of increased central venous pressure, often seen in fluid overload rather than fluid volume deficit.
