Exam 32: Fluid and Electrolyte Balance

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

Blood hydrostatic pressure tends to force fluid out of capillaries and into interstitial fluid.

The body tissue with the least amount of water is bone.

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?

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

When comparing the volume of the various body fluids,the correct order going from highest to lowest in total volume would be:

The most accurate measurement of the body's store of potassium is an arterial blood sample.

In infants,total body water constitutes approximately 40% of body weight.

Match each term related to abnormal conditions with its corresponding definition or explanation. -condition when fluid output exceeds fluid intake and results in a decrease in total body water

The most crucial mechanisms for maintaining fluid balance adjust output to intake,as in the aldosterone mechanism and the renin-angiotensin mechanism.

When compared chemically,intracellular fluid and plasma are almost identical.

The dissociated particles of an electrolyte are called ions.

Strenuous physical activity on a hot day can generate as much as 5 L of sweat a day.

Positive ions of electrolytes are cations and are attracted to a cathode.

When the posterior lobe of the pituitary is stimulated to increase its secretion of ADH,the first event to occur is a(n):

If a solution of sodium (Na⁺,atomic weight = 23)and a solution of calcium (Ca²⁺,atomic weight = 40)had equal mg%,what would be the mEq/L of each?

Burns,infections,and shock may lead to an increase in plasma proteins,which then causes fluid imbalance.

The total body potassium content may be 1000 times greater than the serum potassium level.

Osmoreceptors associated with thirst are located in the gastrointestinal tract.

In patients with severe burn injuries,what mechanism is responsible for the increased risk of hypovolemic shock?
