Which statement by a client taking furosemide (Lasix) indicates a need for further instruction?

The statement indicating a need for further instruction is the one about expecting ringing in the ears. Furosemide, a loop diuretic, is known to have the potential side effect of ototoxicity, which can manifest as tinnitus or ringing in the ears, particularly when the medication is administered at high doses or rapidly via intravenous route. However, it is not a symptom that clients should anticipate as a normal effect of the medication; rather, it should be reported to their healthcare provider if it occurs.

The other statements reflect important aspects of managing treatment with furosemide. Monitoring weight daily helps in recognizing fluid retention, which is crucial for evaluating the drug's effectiveness. A diet high in potassium is typically advised because furosemide can lead to potassium depletion, making potassium-rich foods essential in maintaining normal levels and preventing hypokalemia. Experiencing increased urination is an expected outcome of taking a diuretic, as this medication works primarily by increasing urine output to reduce fluid overload. Each of these aspects is integral to proper patient education regarding the use of furosemide.
