Exam 43: Fluid and Electrolyte Balance

Movement of water and solutes between ECF and ICF spaces is influenced by all of the following except:

What is the most abundant anion in the extracellular fluid?

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

Chemical similarity predominates between the two extracellular fluids.

Which of the following is not considered an extracellular fluid?

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

If two electrodes charged with a weak current were placed in a solution of NaCl, the positive electrode would attract:

The tonicity of a solution is not important when it is administered subcutaneously.

The release of aldosterone can cause an increase in the blood colloid osmotic pressure.

Match each term with its corresponding definition. -Type of compound that dissociates into ions when dissolved in water

The thirst center is located in the hypothalamus and SFO of the brain.

Acidosis can be rapidly treated by the intravenous administration of lactate.

The chief means of regulating body sodium levels is through sweat loss.

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

Interstitial fluid contains an appreciable amount of protein anions, whereas blood contains hardly any.

Parenteral solutions are given to:

A change in electrolyte balance will have little effect on fluid balance.

Abnormal conditions that cause fluid and electrolyte output to exceed input include all the following except:

The reactivity or combining power of an electrolyte depends solely on the number of molecular particles present.

Thirst is associated with any condition that decreases total volume of body water, such as blood loss or hemorrhage.
