A nurse is analyzing the laboratory data on a client who has dehydration. Which finding should the nurse anticipate in a client who has fluid volume deficit?
Decreased serum osmolarity
Decreased hematocrit
Elevated blood urea nitrogen (BUN)
Lower urine specific gravity
The Correct Answer is C
A. Decreased serum osmolarity: Fluid volume deficit typically leads to an increase in serum osmolarity due to concentration of solutes in the blood, not a decrease.
B. Decreased hematocrit: Dehydration causes hemoconcentration, leading to an increase in hematocrit, not a decrease.
C. Elevated blood urea nitrogen (BUN): Dehydration results in decreased renal perfusion and concentration of urea in the blood, leading to elevated BUN levels.
D. Lower urine specific gravity: Dehydration causes increased urine concentration, resulting in higher urine specific gravity, not lower.
