A nurse is assisting in the care of a male client who has a new prescription for furosemide. Which of the following client findings should the nurse identify as a contraindication to the administration of furosemide?
Correct Answer: A
Rationale: Furosemide, a loop diuretic, treats heart failure but depletes potassium, risking hypokalemia. A low potassium level (e.g., <3.5 mEq/L) contraindicates its use hypokalemia causes arrhythmias, especially with heart failure's cardiac strain, per pharmacology standards. Blood pressure matters hypotension may worsen with diuresis but isn't a direct contraindication unless extreme. Digoxin use heightens hypokalemia risk (enhancing toxicity), but potassium level drives the decision. The client's report of diarrhea and thirst suggests dehydration, a caution, not a strict contraindication. Low potassium demands correction (e.g., supplements) before furosemide, preventing lethal complications like ventricular fibrillation, making it the critical finding to identify.
