What effect can moderate to severe hypokalemia have on digoxin therapy?
A. Hypokalemia increases the excretion rate of digoxin; therefore, digoxin must be given twice each day.
B. Hypokalemia increases the half-life of digoxin; therefore, digoxin must be given every other day.
C. Hypokalemia increases the sensitivity of excitable membranes to digoxin; there-fore, toxic effects may occur with normal doses.
D. Hypokalemia decreases the sensitivity of excitable membranes to digoxin; there-fore, higher doses of digoxin are required to achieve a therapeutic effect.
C
Digoxin exerts its effects by binding to the potassium receptor site (competing with potassium) on the myocardial membrane. When serum potassium levels are below normal, more potassium receptor sites are bound with digoxin, allowing it to exert a greater effect at the same dosage.
