Answer to Question 1

ANS: B
Persistent hypoxemia that occurs with tetralogy of Fallot stimulates erythropoiesis, which results in polycythemia, an increased number of red blood cells.

Answer to Question 2

ANS: B
A fall in the serum potassium level enhances the effects of digoxin, increasing the risk of digoxin toxicity. Increased serum potassium levels diminish digoxin's effect. Therefore, serum potassium levels (normal range, 3.55.5 mmol/L) must be carefully monitored.
