The nurse is teaching parents about antepartum testing. Which statements should the nurse include?
Explanation & Rationale
Choice A rationaleAmniocentesis assesses fetal lung maturity, genetic disorders, and infections, not preeclampsia. Preeclampsia diagnosis involves blood pressure, proteinuria, and other lab tests. Normal blood pressure: 300 mg/day.Choice B rationaleA non-stress test measures fetal heart rate response to movements, evaluating fetal well-being. Normal fetal heart rate: 110-160 bpm. Accelerations: 15 bpm increase for at least 15 seconds.Choice C rationaleChorionic villus sampling assesses chromosomal abnormalities, genetic disorders, not neural tube defects. Neural tube defect screening: maternal serum alpha-fetoprotein levels, ultrasound. Normal alpha-fetoprotein: 0.5-2.5 MoM.Choice D rationaleA full bladder helps lift the uterus for better visualization during ultrasound, especially in early pregnancy. This improves image quality for assessing fetal development and other structures.Choice E rationaleOral glucose tolerance test assesses gestational diabetes by measuring blood glucose levels, not fetal activity. Normal fasting blood glucose:
