A 68-year-old woman presents to the clinic with symptoms and signs of CHF. Which of the following is a contraindication to use furosemide?
Furosemide is related to sulfonamide, and severe allergic reactions can occur. Furosemide is effective despite gross electrolyte disturbances or hypoalbuminemia. Excretion of large volumes of bicarbonate-poor urine leads to alkalosis, so an acidosis is not a contradiction in severe fluid and electrolyte depletion; a trial in oliguric states is often appropriate.
has hypoalbuminemia
is oliguric
has acidosis
had a rash with trimethoprim-sulfamethoxazole
