Quizplus · Accepted Answer

The L/S (lecithin-sphingomyelin) ratio is used to assess lung maturity. A ratio of 2:1 or greater indicates sufficient surfactant production for neonatal lung function, making option A the correct choice. White blood cells and leukocyte esterase are not indicative of lung maturity. Lamellar bodies, while an indirect measure of lung maturity, do not provide a specific threshold for sufficient lung function.
