Question 1 pts
pH is a measurement of the:
➔ hydrogen ion concentration of a solution.
hydroxide ion concentration of a solution.
amount of buffer needed in a solution.
amount of electrolytes in a solution.
DIF: Remembering
REF: p. 476
OBJ: 1
TOP: pH of body fluids
Question 2 pts
A solution with a pH of 7.0:
would have more hydrogen ions than hydroxide ions.
would have fewer hydrogen ions than hydroxide ions.
➔ would have an equal number of hydrogen and hydroxide ions.
, would be an acid solution.
DIF: Applying
REF: p. 476
OBJ: 1
TOP: Using the pH scale
Question 3 pts
A solution with a pH of 9.0 would:
be an acid solution.
➔ have fewer hydrogen ions than hydroxide ions.
be neutral.
have more hydrogen ions than hydroxide ions.
DIF: Applying
REF: p. 476
OBJ: 1
TOP: Using the pH scale
Question 4 pts
A solution with a pH of 5.0 would:
be a basic solution.
➔ have more hydrogen ions than hydroxide ions.
be neutral.
have more hydroxide ions than hydrogen ions.
DIF: Applying
REF: p. 476
OBJ: 1
TOP: Using the pH scale
Question 5 pts
A solution with a pH of 7.0 would:
have more hydrogen ions than hydroxide ions.
be an acid solution.
➔ be a neutral solution.
have more hydrogen ions than hydroxide ions and be a neutral solution.
DIF: Remembering
REF: p. 476
OBJ: 1
TOP: Using the pH scale
, Question 6 pts
If saliva has a pH of 7.7, arterial blood has a pH of 7.45. That means:
arterial blood is more alkaline than saliva.
➔ arterial blood is more acidic than saliva.
saliva has more hydrogen ions than arterial blood.
saliva has the same hydrogen ions as arterial blood.
DIF: Applying
REF: p. 476
OBJ: 1
TOP: Using the pH scale
Question 7 pts
The mechanism used by the body to regulate body pH is:
the buffer system only.
the respiratory mechanism only.
the urinary mechanism only.
➔ the buffer system, respiratory mechanisms, and urinary mechanisms.
DIF: Remembering
REF: p. 477
OBJ: 2
TOP: Mechanisms that control pH of body fluids
Question 8 pts
The slightly lower pH of venous blood compared to arterial blood is caused by:
the lower oxygen level of venous blood.
the influx of lactic acid in venous blood.
➔ the influx of carbon dioxide in venous blood.
the influx of carbon dioxide in arterial blood.
DIF: Remembering
REF: p. 477
OBJ: 2
TOP: Mechanisms that control pH of body fluids
r•ii+H
Question 9 pts

have minimal effect on the pH of a solution.
DIF: Remembering
REF: p. 478
OBJ: 2
TOP: Chemical pH control mechanisms
Question 11 pts
Metabolism tends to add:
more bases than acids to the blood.
➔ more acids than bases to the blood.
about an equal amount of acids and bases.
only neutral substances to the blood.
DIF: Remembering
REF: p. 478
OBJ: 2
TOP: Chemical pH control mechanisms
Question 12 pts
The results of metabolic processes usually add:
relatively weak bases to the blood.
relatively strong bases to the blood.
relatively weak acids to the blood.
