Pharm & IV · Cardiac

1 / 4

A client with heart failure is started on furosemide 40 mg IV daily. Which laboratory value is most important for the nurse to monitor?

Not quite — here's why

Furosemide is a loop diuretic that increases renal excretion of potassium, so hypokalemia is the most common and dangerous electrolyte disturbance — it potentiates dysrhythmias, especially if the client is also on digoxin. Calcium, albumin, and bilirubin are not directly affected by loop diuretic therapy.

The product

What's inside.

A question bank, timed exam mode, and flashcards built from your own mistakes. The pieces every NCLEX candidate needs, in one place.

Next Gen NCLEX: every item is written to drill the clinical judgment the NGN leans on — read the cues, prioritize, choose the safest action — and every choice gets a rationale, not just the right one. Item types are four-option, single-answer today; NGN case studies and extended items aren't in the bank yet.

Question bank

NCLEX-style practice questions with full rationales. Answer, check your reasoning, and Scruba tracks what you keep missing.

Exam mode

A timed run on the same bank — no feedback until the end, then a full review of every item, scored against the 75% target exam mode holds you to.

Flashcards from your misses

Every question you get wrong becomes a flashcard automatically, so you revise the concepts you actually missed instead of the ones you already know.

Missed-question review

Go back through everything you got wrong with the full reasoning, the correct answer, and the takeaway — all in one place.

Recall drills
