A decrease in blood pressure
A decrease in blood sugar
A decrease in urine output
A decrease in specific gravity
The Correct Answer is C
A. Vasopressin does not typically affect blood pressure significantly.
B. Vasopressin is not used to lower blood sugar levels; it is primarily used for water retention.
C. Vasopressin, also known as antidiuretic hormone (ADH), acts on the kidneys to decrease urine output, making this the expected outcome of therapy.
D. Specific gravity of urine may increase with vasopressin therapy due to decreased urine output, rather than decrease.

Explanation
A. Metabolic acidosis is characterized by a low pH and low bicarbonate levels (HCO3).
B. Metabolic alkalosis is characterized by a high pH and high bicarbonate levels (HCO3).
C. Respiratory alkalosis is characterized by a high pH and low PaCO2 levels.
D. The pH is below the normal range (7.35-7.45), indicating acidosis. The PaCO2 is elevated, indicating respiratory acidosis, as an increase in PaCO2 leads to an increase in carbonic acid and a decrease in pH.
