Final answer:
Patients with class-IV CHF often have a medication regimen consisting of metoprolol
Step-by-step explanation:
The statement that a patient with class-IV CHF has a medication regimen consisting of metoprolol is true. Metoprolol is a medication commonly used in the management of congestive heart failure (CHF). It is a beta-blocker that helps reduce the workload on the heart, improve symptoms, and decrease the risk of hospitalization in patients with CHF. Therefore, in class-IV CHF, metoprolol is often prescribed to help manage the condition.
