Chapter 26, Problem 22RAC
Summary Introduction
Introduction:
Urine is a waste product that is produced to excrete cellular waste. It also helps in regulating the amount of water, the blood volume and blood pressure of the body which is a part of homeostasis. There are some other factors that are also involved in regulating blood volume and urine formation such as renin-angiotensin system and anti-diuretic hormone feedback system.

If an ARB is prescribed, you would likely expect which one of the following?
●A. the production of angiotensin II would decrease
●B. the amount of aldosterone released would decrease
●C. this drug would affect the heart but not blood vessels
●D. there would be a persistent cough in your patient
Both ADH and aldosterone act to a.increase urine volume. b.increase blood volume. c.increase total peripheral resistance. d.produce all of these effects.
explain how/why diuretics that block ADH secretion would work to reduce blood pressure (ie, what ASPECT of blood pressure is affected, and how is it affected)
