Final answer:
The nurse would expect the provider to order an Aldosterone antagonist to counter the fibrotic changes in the heart and vessels caused by heart failure and the use of an ACE inhibitor.
Step-by-step explanation:
The nurse would expect the provider to order an Aldosterone antagonist to counter the fibrotic changes in the heart and vessels caused by heart failure and the use of an ACE inhibitor. Aldosterone antagonists block the action of aldosterone, a hormone that promotes sodium and fluid retention, which can contribute to fibrotic changes.
