Your patient is breathing with a
increasing Ve that peaks then
apnea follows
a. Biots breathing
b. Apneustic breathing
c. Cheye-Stokes breathing
d. Central neurogenic
hypoventilation
A person who is sedated deeply
may breathe irregularly because
he is suffering from:
a. Biot’s breathing
b. Apneustic breathing
c. Cheye-Stokes breathing
d. Central neurogenic
hypoventilation
This abnormal breathing
pattern results from increased
intracranial pressure and
results in apnea periodically
between times of normal
breathing.

Review # 4
1.
The waste produces of metabolism
include excessive acids. To deal with these
acids, the renal system must:
a. excrete H+ and keep HC03b. excrete HC03- and keep H+
c. excrete both HC03- and H+
d. none of these
2.
The renal system's functional
unit, called the____, is
constructed of a series of blood
vessels surrounding a renal
tubular.
a. Alveoli
b. Capillary
c. Bowman's capsule
d. Nephron
3.
TRUE/FALSE Inside the
tubular, as the filtrate moves
along, the H+ are captured by
various substances [buffers] so
that they cannot return to the
blood stream.
4.
TRUE/FALSE The pH of the
blood rises as the H+ leaves the
filtrate.
5.
As C02 enters the renal cell,
HC03- and H+ are created by
the rapid increase of C02
hydrolysis in the presence of ----in the renal system.
a.
b.
c.
d.
Capillaries
Carbon dioxide
Carbamino
Carbonic anhydrase
Page 3
6.
TRUE/FALSE The renal cells
actively transport H+ into the
filtrate via counter transport in
which Na+ exchanges place with
the H+.
7.
TRUE/FALSE But HC03- can
return to the bloodstream, as
C02 due to the rapid hydrolysis
of C02 inside the renal cell.
8.
Once in the filtrate, ammonia
can accept H+ and the result is
[an ammonium ion.]
a.
b.
c.
NH4+
NHNaHC03-
9.
TRUE/FALSE Because it
captured the H+, ammonia is a
buffer.
10.
In the renal system, the H+ are
captured by:
a.
b.
c.
d.
11.
Ammonia
Phosphate
Both
None
The pH of the urine of the
normal person is about:
a. 8.0
b. 7.0
c. 6.0
d. 5.0
