In this concise instructional video, the presenter explains that furosemide is a potent loop diuretic that rapidly removes large volumes of fluid and electrolytes. The key adverse effects highlighted are hypotension and electrolyte deficiencies—including hyponatremia, hypocalcemia, hypochloremia, and hypokalemia—resulting from the drug’s aggressive diuresis. A high‑yield NCLEX focus is emphasized: tinnitus (ringing in the ears) is a classic side effect that exam writers frequently test. The speaker advises nursing students to consider both the fluid‑electrolyte shifts and the tinnitus risk when caring for patients on furosemide. The video concludes with a brief plug for a pharmacology study system available in the Nursing SOS shop.

Let's talk about some key side effects to know for furosemide. So furosemide is a very powerful diuretic. And what this medication is going to do is it's going to kick out a ton of fluid and electrolytes from the body. So side effects that can happen with furosemide is hypotension, so that because of that lack of fluid volume, the patient could have hyponatremia, hypocalcemia, hypochloremia, and hypokalemia. So think about this. When furosemide is kicking those electrolytes out, we're going to see those lower levels. So, so that makes sense. Now, another really key NCLEX point for you here. A side effect that the NCLEX really likes to test on is tinnitus. So that ringing in the ears. So when you think furosemide, think of tinnitus, because the NCLEX really, really likes to test on that one. But make sure you're also thinking about how it's going to alter the fluid and electrolyte status of your patient.
