Answer to Question 1

ANS: B
Hypokalemia may occur as a natural consequence of increased erythrocyte production. As large numbers of new erythrocytes are produced, levels of free potassium may fall, resulting in hypokalemia.
Hypokalemia, not hyperkalemia, may occur as a consequence of increased erythrocyte production.
Monitoring of calcium is not indicated.

Answer to Question 2

ANS: B
Given the patient's symptoms, and because the individual is postop, the risk for bleeding exists, and measurement of the hemoglobin and hematocrit is a good means of detecting this.
Stool tests for guaiac are not indicated unless GI bleeding is suspected.
A platelet count would be indicated, but not before measurement of Hgb and Hct, which are the best indicators of bleeding.
Hypertonic fluids are not indicated, although isotonic fluids may be indicated.
