A client who is receiving sodium bicarbonate for an acid–base imbalance should also have blood levels monitored for which drug?
1. Digoxin (Lanoxin)
2. Spironolactone (Aldactone)
3. Potassium supplement
4. Lithium (Eskalith)
Correct Answer:
Rationale 1: Digoxin (Lanoxin) is incorrect because digoxin levels should be monitored for clients taking diuretics.
Rationale 2: Spironolactone (Aldactone) is a potassium-sparing diuretic, and potassium supplements should be initiated in clients taking a loop or thiazide diuretic.
Rationale 3: Potassium supplement is incorrect because spironolactone is a potassium-sparing diuretic, and potassium supplements should be initiated in clients taking a loop or thiazide diuretic.
Rationale 4: Sodium bicarbonate can increase the elimination of lithium, and blood levels should be monitored in clients taking this drug to maintain therapeutic levels.
