A nurse is reviewing a client's medication administration record. Which of the following medications should the nurse recognize as potentially interacting with the client's prescribed lithium?

A. Furosemide, a loop diuretic, can increase lithium levels by reducing renal clearance of lithium, leading to lithium toxicity. Monitoring lithium levels and adjusting the dose as necessary is essential when co-administered with furosemide. B. Gentamicin, an aminoglycoside antibiotic, is not known to interact significantly with lithium. C. Alprazolam, a benzodiazepine, is not known to interact significantly with lithium. D. Warfarin, an anticoagulant, is not known to interact significantly with lithium.
