2. Furosemide (Lasix) produces rapid diuresis and blocks reabsorption of sodium and water in renal tubules.
3. Spironolactone (Aldactone) is a maintenance diuretic that is potassium-sparing. Hypokalemia would increase the risk of Lanoxin toxicity.
4. Angiotensin-converting enzyme (ACE) inhibitors promote vascular relaxation.
