1If the H   + concentration in the blood increases, bicarbonate ions act as buffers by

combining with Cl  −.

releasing H  + into the plasma.

dissociating into H+ and CO  3  −.

removing excess H  + from the plasma.         

2Which of the following is not a function of the carbonic acid/bicarbonate system?

Regulating pH changes of the blood during exercise.

Regulation of blood pH in coordination with the respiratory system.

Regulation of the pH of the intracellular environment.

Regulation of blood pH during elevated fat metabolism.

3 Urine is prevented from flowing back into the ureters from the bladder by __________.

the internal urethral sphincter

the ureteral sphincters

compression of the ureteral openings

the external urethral sphincter

4Once alkalosis has occurred, which of the following would you expect to happen?

A plasma pH less than 7.40

10Which of the following regulatory mechanisms would be stimulated as a result of the increased osmolality that results from a Na   + level of 152 mEq/L?

An increased release of ADH

An increase in the secretion of aldosterone

An increase in renin production

11The increase in extracellular osmolality would cause

water to move out of the cells.

no change in the net movement of water into or out of the cells.

water to move into the cells.

12The K   + level of 2.8 mEq/L indicates hypokalemia. Low plasma K   + levels will cause__________.

thirst

muscle weakness

tremors, tetany, and convulsions

increased body temperature

13Decreased blood colloid osmotic pressure affects renal function by

increasing capsular pressure.
