What types of over-the-counter drugs can worsen high blood pressure? a. Drugs for asthma b. Laxatives c. Cortisone creams d. Aspirin 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.

How do angiotensin-converting enzyme (ACE) inhibitors lower blood pressure? a. Preventing clots from forming b. Promoting water and potassium retention c. Relaxing blood vessel muscles d. Reversing atherosclerosis 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. DIF: Cognitive Level: Remembering REF: p. 257 6. Which side effect of ACE inhib [Show More]
