The most important factor influencing the survival of a 30-week fetus born prematurely is
a. deficient surfactant levels c. pronounced throm-bocytopenia
b. inadequate thermal stimuli d. reduced capillary permeability
A
Deficient surfactant levels is the most important factor influencing the survival of a 30-week fetus born prematurely. Although surfactant normally begins to be secreted in the lungs at 28 weeks gestation, it takes at least another 8 weeks for sufficient surfactant to be secreted and distributed throughout the alveoli. Hypothermia frequently is manifested as neonatal respiratory distress. However, this is not the major problem for the 30-week preterm neonate. Pronounced thrombocytopenia and reduced capillary permeability are not appropriate causes for neonatal respiratory distress.
