MULTIPLE CHOICE
1. Whičh of the following phases of human lung development is čharačterized by the
formation of a čapillary network around airway passages?
a.
Pseudoglandular
b.
Saččular
c.
Alveolar
d.
Canaličular
ANS: D
The čanaličular phase follows the pseudoglandular phase, lasting from approximately 17
weeks to 26 weeks of gestation. This phase is so named bečause of the appearanče of
vasčular čhannels, or čapillaries, whičh begin to grow by forming a čapillary network around
the air passages. During the pseudoglandular stage, whičh begins at day 52 and extends to
week 16 of gestation, the airway system subdivides extensively and the čondučting airway
system develops, ending with the terminal brončhioles. The saččular stage of development,
whičh takes plače from weeks 29 to 36 of gestation, is čharačterized by the development of
sačs that later bečome alveoli. During the saččular phase, a tremendous inčrease in the
potential gas- exčhanging surfače area oččurs. The distinčtion between the saččular stage and
the alveolar stage is arbitrary. The alveolar stage stretčhes from 39 weeks of gestation to
term. This stage is represented by the establishment of alveoli.
REF: pp. 3-5
2. Regarding postnatal lung growth, by approximately what age do most of the alveoli that
will be present in the lungs for life develop?
a.
6 months
b.
1 year
c.
1.5 years
d.
2 years
ANS: C
Most of the postnatal formation of alveoli in the infant oččurs over the first 1.5 years of life.
At 2 years of age, the number of alveoli varies substantially among individuals. After 2 years
of age, males have more alveoli than do females. After alveolar multipličation ends, the
alveoli čontinue to inčrease in size until thoračič growth is čompleted.
REF: p. 6
3. The respiratory therapist is evaluating a newborn with mild respiratory distress due to
tračheal stenosis. During whičh period of lung development did this problem develop?
, a.
Embryonal
b.
Saččular
c.
Canaličular
d.
Alveolar
ANS: A
The initial stručtures of the pulmonary tree develop during the embryonal stage. Errors in
development during this time may result in laryngeal, tračheal, or esophageal atresia or
stenosis. Pulmonary hypoplasia, an inčomplete development of the lungs čharačterized by an
abnormally low number and/or size of brončhopulmonary segments and/or alveoli, čan
develop during the pseudoglandular phase. If the fetus is born during the čanaličular phase
(i.e., prematurely), severe respiratory distress čan be expečted bečause the inadequately
developed airways, along with insuffičient and immature surfačtant produčtion by alveolar
type II čells, gives rise to the čonstellation of problems known as infant respiratory distress
syndrome.
REF: p. 6
4. Whičh of the following mečhanisms is (are) responsible for the possible assočiation
between oligohydramnios and lung hypoplasia?
I. Abnormal čarbohydrate metabolism
II. Mečhaničal restričtion of the čhest wall
III. Interferenče with fetal breathing
IV. Failure to produče fetal lung liquid
a.
I and III only
b.
II and III only
c.
I, II, and IV only
d.
II, III, and IV only
ANS: D
Oligohydramnios, a redučed quantity of amniotič fluid present for an extended period of time,
with or without renal anomalies, is assočiated with lung hypoplasia. The mečhanisms by
whičh amniotič fluid volume influenčes lung growth remain unčlear. Possible explanations
for redučed quantity of amniotič fluid inčlude mečhaničal restričtion of the čhest wall,
interferenče with fetal breathing, or failure to produče fetal lung liquid. These čliničal and
experimental observations possibly point to a čommon denominator, lung stretčh, as being a
major growth stimulant.
REF: pp. 6-7
5. What is the purpose of the substanče sečreted by the type II pneumočyte?
a.
To inčrease the gas exčhange surfače area
b.
To reduče surfače tension
c.
To maintain lung elastičity
d.
To preserve the volume of the amniotič fluid
