Exam 43: Fluid and Electrolyte Balance

A 70-kg (154-lb) adult has a total body sodium pool of approximately 2800 to 3000 mEq.

The amounts of antidiuretic hormone and aldosterone secreted determine the amount of water reabsorbed in the tubules.

In recent years, Ringer solution has frequently been used instead of normal saline.

A person who is dehydrated will need replacement of water and electrolytes.

Milligram percent is the most common unit used to measure electrolyte concentration.

Edema is defined as abnormally large amounts of fluid in the:

What is the most abundant cation in intracellular fluid?

As related to the Starling law, which of the following is the greatest pressure at the arterial end of the capillaries?

Ingested liquids are the major source of water for the body, followed by water formed from a catabolism, with a smaller amount coming from water in foods.

Which of the following is true of total body water?

What are two means of obligatory water loss?

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

Angiotensin I and angiotensin II increase the secretion of aldosterone.

Match each term related to abnormal conditions with its corresponding definition or explanation. -A condition of decreased serum sodium concentration below the normal range

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

Match each term related to abnormal conditions with its corresponding definition or explanation. -A serum potassium level substantially above normal

List the four pressures associated with the Starling law of the capillaries. Explain what the effects are of these pressures in terms of moving fluid into or out of the capillaries.

Both a decrease in potassium ions and a decrease in blood pressure will stimulate the release of aldosterone.

When chloride is secreted in the urine, it is often linked with sodium.

Edema can be defined as the presence of an abnormally large amount of intracellular fluid.
