Type II alveolar cells are among the last cells to mature during fetal development.In babies born prematurely,type II alveolar cells are often not ready to perform their functions.Which of the following drugs would be most likely to help an infant with immature type II alveolar cells?

Question

Quizplus · Accepted Answer

Pulmonary surfactant helps in reducing surface tension in the alveoli, which is necessary for efficient gas exchange. Premature infants with immature type II alveolar cells often do not produce enough pulmonary surfactant, leading to respiratory distress syndrome. Administering exogenous pulmonary surfactant can help improve lung function in these infants. Beta-adrenergic agonists, muscarinic agonists, and histamine are not directly related to surfactant production and may not be effective in treating this condition. Beta-adrenergic antagonists can actually worsen respiratory distress by decreasing bronchodilation.
