Which of the following tests is used to assess fetal lung maturity?
- A. Non-stress test
- B. Biophysical profile
- C. Amniocentesis
- D. Lecithin-sphingomyelin (L/S) ratio
Correct Answer: D
Rationale: The correct answer is D: Lecithin-sphingomyelin (L/S) ratio. This test is used to assess fetal lung maturity by measuring the ratio of two substances found in the amniotic fluid. An L/S ratio greater than 2:1 is indicative of mature fetal lungs. This test is crucial in determining if a baby can breathe adequately after birth. The other choices are incorrect because: A) Non-stress test monitors fetal heart rate and movements, B) Biophysical profile assesses fetal well-being, and C) Amniocentesis is a procedure to collect amniotic fluid for genetic testing.
