The nurse is assessing a client who has hypovolemic shock. Which laboratory value indicates that the client is at risk for acidosis?
a. Decreased serum creatinine
b. Increased serum lactic acid
c. Increased urine specific gravity
d. Decreased partial pressure of arterial car-bon dioxide
B
The syndrome of hypovolemic shock results in inadequate tissue perfusion and oxygenation; thus some cells are metabolizing anaerobically. Such metabolism increases the production of lactic acid, resulting in an increase in hydrogen ion production and acidosis. Other laboratory values associated with acidosis include increased creatinine (impaired renal function) and increased par-tial pressure of arterial carbon dioxide. Urine specific gravity is not associated with acidosis.
