Exam 43: Fluid and Electrolyte Balance

Match each term with its corresponding definition. -Substance that enters the body through injection and not through the alimentary canal

The milliequivalent is a measure of the weight of an electrolyte.

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

Hypochloremia is frequently linked to cases of potassium loss.

Urine volume is regulated mainly by hormones secreted by the posterior lobe of the pituitary gland and by the adrenal cortex.

Which of the following two forces tend to move fluid out of the blood vessel?

Cell breakdown may lead to a potassium deficiency in the body.

Describe the functioning thirst center. Where is it located?

Which of the following pairs are almost identical when compared chemically?

When the sum of the blood hydrostatic pressure and the interstitial fluid colloid osmotic pressure is greater than the sum of the interstitial fluid hydrostatic pressure and the blood colloid osmotic pressure, fluid shifts out of the interstitial fluid and into the blood.

Explain the relationship between the sodium concentration in the interstitial fluid and the chloride concentration, between the potassium concentration and the chloride concentration.

The only functionally important difference between blood plasma and interstitial fluid is the presence of more protein anions in plasma.

To be effective, a diuretic (drug that increases water loss through the kidneys) should not only increase water loss but also increase sodium loss. Why?

Which body location is not one that is usually impacted by edema?

Fluid tends to be pushed out of the blood vessels at the venous end and reabsorbed at the arterial end.

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

Intracellular fluid is the only fluid that usually contains protein.

Compare the volumes of the body fluid compartments in the infant, the adult male, and the adult female.

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

Hydrostatic pressure serves as the chief regulator of water transfer between intracellular and interstitial fluid.
