Question

1. which of the following cardiac disease drugs work by dilating the arteries and making it easier for the heart to pump blood? a○alpha blockers b○anti - arrhythmias c○beta blockers d○calcium channel blockers

Explanation:

Calcium channel blockers work by blocking the entry of calcium into the cells of the heart and blood - vessel walls, which causes the arteries to dilate, reducing the workload on the heart and making it easier for the heart to pump blood. Alpha - blockers mainly work on blocking alpha - adrenergic receptors to relax blood vessels. Anti - arrhythmics are used to treat abnormal heart rhythms. Beta - blockers block the effects of adrenaline on the heart.

Answer:

D. Calcium channel blockers
