The specific gravity (relative density) of
A. Red cells is less than that of plasma.
B. Plasma is due more to its protein than to its electrolyte content.
C. Plasma decreases as extracellular fluid and electrolytes are lost.
D. Blood is higher on average in women than in men.
E. Urine can fall below 1.000 in a water diuresis
A. Incorrect – Red cells have a higher specific gravity than plasma. B. Correct – Plasma’s specific gravity is influenced more by protein content. C. Generally correct – Plasma volume decreases with the loss of extracellular fluid and electrolytes. D. Incorrect – Blood specific gravity is typically higher in men than in women. E. Correct – Urine can have a specific gravity below 1.000 during water diuresis.
