When a premature newborn is showing signs of developing respiratory distress syndrome or bronchopulmonary dysplasia, which of the following treatments is most likely given to reduce the chance of the infant having these problems?
a. exogenous surfactant therapy c. hyperbaric chamber treatments
b. oxygen therapy d. light therapy
A
Feedback
A Correct. Surfactant production begins around 24 weeks of gestation. Preterm infants lack adequate surfactant for effective lung functioning. Without adequate surfactant, these infants are at high risk for developing respiratory distress syndrome or bronchopulmonary dysplasia. Treatment with exogenous surfactant therapy at birth effectively decreases the incidence of these respiratory alterations.
B Incorrect. Treatment with humidified oxygen therapy is secondary to the administration of exogenous surfactant therapy.
C Incorrect. Hyperbaric chamber treatments are not indicated to increase the surfactant level adequate for effective lung functioning.
D Incorrect. Light therapy is not indicated to increase the surfactant level adequate for effective lung functioning.
