Question

Quizplus · Accepted Answer

Furosemide is a loop diuretic that promotes the excretion of fluid and electrolytes, including potassium. The combination of furosemide and prednisone can increase the risk of hypokalemia, which can cause adverse effects such as cardiac arrhythmias. A potassium level of 3.0 mmol/L indicates hypokalemia and is a reason to withhold the next dose of furosemide. A potassium level of 5.5 mmol/L is within the normal range and does not require the drug to be held. Blood pressure of 166/88 is elevated, but it is not a reason to withhold furosemide. Urine output of 900 ml/24 hrs is low, but not a reason to withhold furosemide.
