2. What condition is a major cause of long-term high blood pressure?

ANS:  A

High blood pressure causes arterial walls to thicken and harden. With atherosclerosis plaques are formed inside the walls of arteries. As arterial walls harden and thicken, the arteries become narrow resulting in increased blood pressure over time.

3. What types of over-the-counter drugs can worsen high blood pressure?

ANS:  A

Patients with hypertension should not take over-the-counter drugs (such as drugs for appetite control, asthma, colds, and hay fever) without asking their prescriber. These drugs can cause worsening of high blood pressure because they all constrict blood vessels.

5. How do angiotensin-converting enzyme (ACE) inhibitors lower blood pressure?

ANS:  C

ACE inhibitors block production of substances that constrict (narrow) blood vessels. They also help decrease the buildup of water and salt in the blood and body tissues. The exact way that these drugs work is not known but they block an enzyme in the body that is necessary for production of angiotensin II (a substance that causes blood vessels to tighten or constrict). The result is that blood vessels relax and blood pressure is decreased.
