Renal Physiology Quiz

A person who chronically consumes large amounts of antacids to settle an upset stomach may risk

metabolic alkalosis.

Prolonged vomiting can result in

metabolic alkalosis.

When large amounts of pure water are consumed,

osmolarities of ECF and ICF decreases.

When the amount of sodium ion in extracellular fluid increases,

osmoreceptors are stimulated.

When water is lost, but electrolytes are retained,

osmosis moves water from the ICF to the ECF.

The primary function of the proximal convoluted tubule is

absorption of ions, organic molecules, vitamins, and water.

In which case is the pH lower? after hyperventilating or after hypoventilating

after hypoventilating

Which of the following is greater? -the amount of ADH released when blood osmolarity is high -the amount of ADH released when blood osmolarity is low

the amount of ADH released when blood osmolarity is high

When the level of sodium ion in extracellular fluid decreases,

the level of aldosterone will increase.

Drugs that promote fluid loss in urine are known as

diuretics.

When the level of ADH (antidiuretic hormone) increases,

less urine is produced.

In response to metabolic alkalosis, the

body retains more carbon dioxide.

The higher the plasma concentration of aldosterone, the more efficiently the kidney will

conserve sodium ions.

Consuming a meal high in salt will

increase the osmolarity of the blood.

Dehydration will cause

increased secretion of ADH.

Aldosterone

promotes sodium retention in the kidneys.

Hypoventilation would cause

respiratory acidosis.

Antidiuretic hormone

stimulates water conservation by the kidneys.
