A patient with acute decompensated heart failure receives an adequate intravenous loop-diuretic dose. Two hours later urine output is 70 mL and spot urine sodium is 34 mmol/L; congestion is unchanged and blood pressure is stable. What is the best diuretic response?

Correct answer: E — Escalated loop diuresis with sequential nephron blockade

The best answer is “Escalated loop diuresis with sequential nephron blockade”. Low early urine sodium and poor urine output indicate an inadequate natriuretic response, supporting prompt dose escalation and, if needed, addition of a mechanistically complementary diuretic. “Continue the same dose for three days before reassessing” is less appropriate because delayed reassessment prolongs congestion after an objectively poor response “Stop all diuretics because low urine sodium proves hypovolaemia” is less appropriate because low post-diuretic urine sodium reflects resistance rather than proving low circulating volume “Give a large crystalloid bolus to increase renal sodium delivery” is less appropriate because routine fluid loading worsens congestion “Start vasopressor therapy despite maintained blood pressure” is less appropriate because vasopressors are not indicated without hypotension or hypoperfusion
