MULTIPLE CHOICE

1. Which of the following phases of human lung development is characterized bythe formation of a
J J J J J J J J J J J J J J J J




capillary network around airway passages? J J J J



a. Pseudoglandular
b. Saccular
c. Alveolar
d. Canalicular
ANS: D J




The canalicular phase follows the pseudoglandular phase, lasting from approximately 17 weeks
J J J J J J J J J J J J




to 26 weeks of gestation. This phase is so named because of the appearance of vascular channels,
J J J J J J J J J J J J J J J J J




or capillaries, which begin to grow by forming a capillary network around the air passages.
J J J J J J J J J J J J J J J




During the pseudoglandular stage, which begins at day 52 and extends to week 16 of gestation,
J J J J J J J J J J J J J J J J




the airway system subdivides extensively and the conducting airway system develops, ending
J J J J J J J J J J J J




with the terminal bronchioles. The saccular stage of development, which takes place from
J J J J J J J J J J J J J




weeks 29 to 36 of gestation, is characterized bythe development of sacs that later become alveoli.
J J J J J J J J J J J J J J J J J




During the saccular phase, a tremendous increase in the potential gas- exchanging surface area
J J J J J J J J J J J J J J




occurs. The distinction between the saccular stage and the alveolar stage is arbitrary. The
J J J J J J J J J J J J J J




alveolar stage stretches from 39 weeks of gestation to term. This stage is represented by the
J J J J J J J J J J J J J J J J




establishment of alveoli. J J




REF: pp. 3-5 J J




2. Regarding postnatal lung growth, byapproximately what age do most of the alveoli that will be
J J J J J J J J J J J J J J J J




present in the lungs for life develop? J J J J J J



a. 6 months J



b. 1 year J



c. 1.5 years J



d. 2 years J




ANS: C J




Most of the postnatal formation of alveoli in the infant occurs over the first 1.5 years of life. At 2
J J J J J J J J J J J J J J J J J J J J




years of age, the number of alveoli varies substantiallyamong individuals. After 2 years of age,
J J J J J J J J J J J J J J J J




males have more alveoli than do females. After alveolar multiplication ends, the alveoli
J J J J J J J J J J J J J




continue to increase in size until thoracic growth is completed.
J J J J J J J J J

3. The respiratorytherapist is evaluating a newborn with mild respiratorydistress due to tracheal
J J J J J J J J J J J J J J




stenosis. During which period of lung development did this problem develop?
J J J J J J J J J J

, a. Embryonal
b. Saccular
c. Canalicular
d. Alveolar
ANS: A J



The initial structures of the pulmonary tree develop during the embryonal stage. Errors in
J J J J J J J J J J J J J J




development during this time may result in laryngeal, tracheal, or esophageal atresia or
J J J J J J J J J J J J J




stenosis. Pulmonaryhypoplasia, an incomplete development ofthe lungs characterized byan
J J J J J J J J J J J J




abnormally low number and/or size of bronchopulmonary segments and/or alveoli, can develop
J J J J J J J J J J J J




during the pseudoglandular phase. If the fetus is born during the canalicular phase (i.e.,
J J J J J J J J J J J J J J




prematurely), severe respiratory distress can be expected because the inadequately developed
J J J J J J J J J J J




airways, along with insufficient and immature surfactant production by alveolar type II cells,
J J J J J J J J J J J J J




gives rise to the constellation of problems known as infant respiratory distress syndrome.

4. Whichofthe following mechanisms is (are) responsible for the possible association between
J J J J J J J J J J J J J




oligohydramnios and lung hypoplasia? J J J




I. Abnormalcarbohydrate metabolism J J




II. Mechanical restriction of the chest wall J J J J J




III. Interference with fetal breathing J J J




IV. Failure to produce fetal lung liquid J J J J J



a. I and III only
J J J



b. II and III only
J J J



c. I, II, and IV only
J J J J



d. II, III, and IV only
J J J J




ANS: D J



Oligohydramnios, a reduced quantityof amniotic fluid present for an extended period of time, J J J J J J J J J J J J J J




with or without renal anomalies, is associated with lung hypoplasia. The mechanisms by which
J J J J J J J J J J J J J J




amniotic fluid volume influences lung growthremain unclear. Possible explanations for reduced
J J J J J J J J J J J J




quantity of amniotic fluid include mechanical restriction of the chest wall, interference with fetal
J J J J J J J J J J J J J J




breathing, or failure to produce fetal lung liquid. These clinical and experimental observations
J J J J J J J J J J J J J




possibly point to a common denominator, lung stretch, as being a major growth stimulant.
J J J J J J J J J J J J J




REF: pp. 6-7 J J




5. What is the purpose of the substance secreted bythe type II pneumocyte?
J J J J J J J J J J J J



a. To increase the gas exchange surface area
J J J J J J



b. Toreduce surface tension
J J J



c. To maintain lung elasticity
J J J



d. To preserve the volume of the amniotic fluid
