A client asks, "Why is my prescription being switched from furosemide to spironolactone?" What is the nurse's best response?
"You will lose less potassium with spironolactone than with furosemide."
"You will have greater potassium losses with spironolactone than with furosemide."
"You will have greater water losses with spironolactone than with furosemide."
"You will have greater sodium losses with spironolactone than with furosemide."
The Correct Answer is A
A. Spironolactone is a potassium-sparing diuretic, meaning it helps retain potassium while promoting sodium and water excretion. This makes it advantageous for clients who may be at risk for hypokalemia with furosemide, which can lead to significant potassium loss.
B. This statement is incorrect; spironolactone causes less potassium loss compared to furosemide, making it a better option for those needing to maintain potassium levels.
C. This statement is misleading; spironolactone does promote diuresis but does not cause greater water losses than furosemide.
D. This is incorrect; while spironolactone does promote sodium excretion, it does not do so to a greater extent than furosemide, which is a more potent diuretic.
