Ch 16:
1. What is the normal pH range of the blood, and what ratio of base to acid does this reflect?
a. 7.32 to 7.42; 25 to 2
b. 7.32 to 7.42; 28 to 2
c. 7.35 to 7.45; 20 to 1
d. 7.35 to 7.45; 30 to 1
2. What are the characteristics of the carbonic acid–bicarbonate buffer system (select all that
apply)?
a. The lungs eliminate CO2
b. Neutralizes HCl acid to yield carbonic acid and
salt
c. H2CO3 formed by neutralization dissociates into H2O and
CO2
d. Shifts H+ in and out of cell in exchange for other cations, such as
potassium and sodium
e. Free basic radicals dissociate into ammonia and OH−, which
combines with H+ to form water
3. What are characteristics of the phosphate buffer system (select all that apply)?
a. Neutralizes a strong base to a weak base and water
b. Resultant sodium biphosphate is eliminated by
kidneys
c. Free acid radicals dissociate into H+ and CO2, buffering excess base
d. Neutralizes a strong acid to yield sodium biphosphate, a weak acid,
and
salt
e. Shifts chloride in and out of red blood cells in exchange for sodium
bicarbonate, buffering both acids and bases
4. A patient who has a large amount of carbon dioxide in the blood also has what in the
blood?
a. Large amount of carbonic acid and low hydrogen ion concentration
b. Small amount of carbonic acid and low hydrogen ion concentration
c. Large amount of carbonic acid and high hydrogen ion
concentration
d. Small amount of carbonic acid and high hydrogen ion concentration
5. What is a compensatory mechanism for metabolic alkalosis?
a. Shifting of bicarbonate into cells in exchange for chloride
b. Kidney conservation of bicarbonate and excretion of hydrogen ions
