An amniocentesis is performed during the prenatal period. A needle is inserted to obtain a sample of amniotic fluid, which can be used to identify chromosomal abnormalities. L/S ratio compares lecithin– phosphatidyl choline to sphingomyelin to identify infant lung maturity. The oxytocin test measures fetal heart rate during contractions induced by oxytocin. A non-stress test measures fetal heart rate while baby is at rest and while baby is moving. Estriol levels in mother’s blood can be a marker for fetal well-being.
Cornell Note-Taking System Instructions:
- Record: During the lecture, use the note-taking column to record the lecture using telegraphic sentences.
- Questions: As soon after class as possible, formulate questions based onthe notes in the right-hand column. Writing questions helps to clarifymeanings, reveal relationships, establish continuity, and strengthenmemory. Also, the writing of questions sets up a perfect stage for exam-studying later.
- Recite: Cover the note-taking column with a sheet of paper. Then, looking at the questions or cue-words in the question and cue column only, say aloud, in your own words, the answers to the questions, facts, or ideas indicated by the cue-words.
- Reflect: Reflect on the material by asking yourself questions, for example: “What’s the significance of these facts? What principle are they based on? How can I apply them? How do they fit in with what I already know? What’s beyond them?
- Review: Spend at least ten minutes every week reviewing all your previous notes. If you do, you’ll retain a great deal for current use, as well as, for the exam.
