A. Increased blood pressure
B. Increased dependent edema
C. Increased urine concentration of potassium
D. Increased hematocrit and hemoglobin levels

The hypertonic saline will increase the osmolarity of the blood (and other extracellular fluids), causing fluid to remain in the plasma volume and drawing fluid from the interstitial space into the plasma volume. The expected early results of these responses are increased blood pressure and decreased edema.
