Exam 32: Fluid and Electrolyte Balance

The mechanism of action for aldosterone and the mechanism of action for ADH differ because ADH regulates water whereas aldosterone regulates:

In parenteral therapy,it is equally important that both intravenous and subcutaneous solutions be isotonic to plasma.

The body fluid that stays constant as a percent of body weight throughout life is:

The major organ that balances sodium and potassium in the body is the:

The two factors that determine urine volume are:

The volume of interstitial fluid is greater than the volume of plasma.

The most important difference between blood plasma and interstitial fluid,when compared chemically,is:

Match each term related to abnormal conditions with its corresponding definition or explanation. -an expansion of fluid volume in the body; a fluid volume excess

In young adults,the percentage of body weight composed of water will average about _____ for males and _____ for females.

Extracellular fluid depletion is the last line of defense against dehydration.

Whereas sodium is the predominant cation in blood plasma,potassium is the predominant cation in intracellular fluid.

The plasma membrane separates the intracellular and extracellular fluid compartments.

Skin "tenting" is a sign of possible dehydration.

When the adrenal cortex is stimulated to increase its secretion of aldosterone,the first thing that happens is a(n):

Match each term with its corresponding definition. -within the cell

A normal saline solution consists of a 9.0% solution of NaCl.

Match each term with its corresponding definition. -force that acts to move fluid out of the tissue space and back into the blood

Because of unknown mechanisms,the secretion of saliva generally increases when there is a decrease in the total volume of body water.

Osmoreceptors assist in controlling homeostasis of body fluids by:

A decrease in solute concentration in the extracellular fluid will cause water to leave the cell in an attempt to compensate.
