An increase in the protein concentration in the plasma would allow more blood to remain in the interim statue fluid
False
As the pH value of a solution goes up, the hydrogen ion concentration goes
up.
False
A possible risk of severe, prolonged vomiting is metabolic acidosis.
False
ADH tends to increase the amount of urine produced.
False
A reduction in capillary blood pressure would allow more blood to be pushed
into the interstitial fluid.
False
A solution with a pH of 5.0 has 100 times more hydrogen ions than a solution
with a pH of 3.0.
False
A newborn can have a percentage of body water as high as
80%
A newborn can have a percentage of body water as high as
80%
A decrease in blood protein concentration would tend to
both a and b above
An increase in capillary blood pressure would tend to
increase interstitial fluid volume
Acidosis occurs when the
blood pH drops
A reduction in capillary blood pressure would allow more blood to be pushed
into the interstitial fluid.
False
ADH tends to increase the amount of water reabsorbed by the body.
True
Carbonic acid access can lead to respiratory alkalosis
False
An increase in capillary blood pressure would tend to
increase interstitial fluid volume
Carbonic anhydrase is an enzyme found in red blood cells.
True
Emphysema or pneumonia can lead to respiratory acidosis.
True
Hyperventilation can cause acidosis.
False
If the blood pH of 7.1 caused a person’s death, the cause of the person’s
death would be acidosis.
True
In the kidney, ammonia is exchanged for sodium bicarbonate.
True
In the blood, the total number of negative ions equals the total number of
positive ions.
True
Lactic acid is an example of a “fixed” acid.
True
Loss of skin elasticity is a clinical sign of overhydration.
False
One reason the amount of water per pound increases in the elderly is that
the muscle mass decreases and body fat increases.
False
One of the results of overhydration is to put too heavy of a burden on the kidneys
False
Overhydration
can be caused by giving intravenous fluids too rapidly
Potassium, calcium, and magnesium are examples of positive ions found in
the body.
True
Potassium, calcium, and magnesium are examples of positive ions found in
the body.
True
The compound glucose is an electrolyte.
False
The kidneys are able to remove base from the body, whereas the lungs can
remove only acid.
True
The enzyme carbonic anhydrase is found
in red blood cells
The compound sodium chloride is an electrolyte.
True
The kidney also can acidify the urine by
by converting an amino group to ammonia
The effect of aldosterone is to increase the volume of the extracellular fluid.
True
The amino group used by the kidney to help remove hydrogen ions is
contributed by a fatty acid molecule.
False
The proper ratio of the buffer pair would be 20 times more carbonic acid than
sodium bicarbonate.
False
The part of the nephron that secretes hydrogen ions into the urine is the
distal tubule
The chief mechanism for maintaining fluid balance is to
adjust fluid output so it equals fluid input
The main water-holding force in the blood capillaries is
protein in the blood plasma
The lungs remove just under 10 liters of carbonic acid from the venous blood
each day.
False
The pH of a solution indicates the solution’s hydrogen ion concentration.
True
Toxic chemicals, such as methanol, can cause respiratory acidosis.
False
The kidneys are able to remove base from the body, whereas the lungs can
remove only acid.
True
The body regulates the amount of fluid lost by increasing or decreasing the
amount of urine produced.
True
With slight variation, the amount of extracellular fluid equals the amount of
intracellular fluid.
False
When the kidney secretes hydrogen ions
None of the above
What term describes the set of processes that the body uses to try to restore
balance when acidosis or alkalosis occurs?
Compensation
When sodium bicarbonate buffers a strong acid, the hydrogen ion from the
acid replaces the carbon in the bicarbonate.
True
Which of the following organs does not contribute to fluid output from the
body?
All of the above organs contribute to fluid output from the body
Which of the following statements is correct?
Females have less water per pound than men
Water intoxication may result from rapidly drinking large volumes of water or
giving hypotonic solutions to persons unable to dilute and excrete urine
normally.
True
When the kidney secretes a hydrogen ion, it absorbs a sodium ion.
True
When the kidney secretes hydrogen ions, it lowers the pH of the urine.
True
What term describes the set of processes that the body uses to try to restore
balance when acidosis or alkalosis occurs?
Compensation
When sodium bicarbonate buffers a strong acid, the hydrogen ion from the
acid replaces the carbon in the bicarbonate.
False
When the kidney secretes hydrogen ions, it lowers the pH of the blood.
False
Where sodium goes, water follows
True
The end products of both aerobic and anaerobic catabolism of glucose can cause a drop in the blood pH.
true
Following cardiac arrest, there is almost an immediate development of
respiratory acidosis
The kidney also can acidify the urine by
by converting an amino group to ammonia
The most important regulator of the amount of sodium in the body is the
kidney
Increased arterial blood pressure causes the baroreceptors to stimulate the release of aldosterone.
false
