A patient with hypertension is taking furosemide (Lasix) for congestive heart failure. The prescriber orders digoxin to help increase cardiac output. What other medication will the nurse expect to be ordered for this patient?
a. Bumetanide (Bumex)
b. Chlorothiazide (Diuril)
c. Hydrochlorothiazide (HydroDIURIL)
d. Spironolactone (Aldactone)
ANS: D
Spironolactone is used in conjunction with furosemide because of its potassium-sparing effects. Furosemide can contribute to hypokalemia, which can increase the risk of fatal dysrhythmias, especially with digoxin administration. The other diuretics listed are all potassium-wasting diuretics.
