Question 67

ACE inhibitors are medications that usually end in '-pril' and are used to relax the blood vessels.

ACE inhibitors, such as lisinopril and enalapril, are specifically designed to inhibit the angiotensin-converting enzyme, leading to the relaxation of blood vessels and a reduction in blood pressure.

A) Beta blockers

Beta blockers are a class of medications that primarily work by blocking the effects of adrenaline on the beta-adrenergic receptors, which slows down the heart rate and reduces blood pressure. They do not typically end in '-pril' and do not primarily function by relaxing blood vessels.

B) Calcium channel blockers

Calcium channel blockers are used to relax blood vessels by preventing calcium from entering the cells of the heart and blood vessel walls. However, they do not end in '-pril' and are a different class of medications, making this option incorrect.

C) ACE inhibitors

ACE inhibitors are the correct choice as they are specifically known for ending in '-pril', such as ramipril and captopril. These medications effectively relax blood vessels by inhibiting the angiotensin-converting enzyme, which lowers blood pressure and decreases the workload on the heart.

D) Statins

Statins are primarily used to lower cholesterol levels in the blood and do not typically have any effect on blood vessel relaxation. They also do not end in '-pril', which makes this option incorrect for the question asked.

Conclusion

ACE inhibitors are the only medications listed that end in '-pril' and are specifically used to relax blood vessels. The other options either belong to different classes of medications or do not share the characteristic of ending with '-pril', confirming that ACE inhibitors are the definitive correct answer.
