Exam 43: Fluid and Electrolyte Balance

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

The nephron has the ability to produce almost sodium-free urine.

Match each term with its corresponding definition. -Specialized cells in the hypothalamus that detect increased solute concentration in extracellular fluid caused by water loss

Angiotensinogen is converted to angiotensin I in the:

Acidosis can be treated rapidly by the intravenous administration of ammonium chloride.

If the other three forces that determine fluid movement were unchanged, an increase in blood hydrostatic pressure would cause edema.

Both ADH and aldosterone cause fluid retention.

Match each term with its corresponding definition. -Unit measuring the number of ionic charges or electrocovalent bonds in a solution; measure of reactivity of a particular electrolyte solution

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