The nurse is teaching parents about antepartum testing. Which statements should the nurse include?
Amniocentesis may be used to assess if you have preeclampsia.
A non-stress test may be used to measure fetal heart rate.
Chorionic villus sampling may be done to assess for neural tube defects.
You may need to fill up your bladder prior to an ultrasound.
Oral Glucose tolerance testing will measure fetal activity at certain intervals.
Correct Answer : B,D
Choice A rationale
Amniocentesis assesses fetal lung maturity, genetic disorders, and infections, not preeclampsia. Preeclampsia diagnosis involves blood pressure, proteinuria, and other lab tests. Normal blood pressure: <120/80 mm Hg. Proteinuria: >300 mg/day.
Choice B rationale
A 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 rationale
Chorionic 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 rationale
A 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 rationale
Oral glucose tolerance test assesses gestational diabetes by measuring blood glucose levels, not fetal activity. Normal fasting blood glucose: <95 mg/dL. 1-hour post-glucose: <180 mg/dL.

Correct Answer is D
Explanation
Choice A rationale
Evaluating the fetal heart rate does not address maternal symptoms of supine hypotensive syndrome. Moving the client first corrects the underlying issue. Fetal evaluation can follow once maternal circulation improves, ensuring both are assessed.
Choice B rationale
Checking recent food and fluid intake does not immediately address the likely cause of supine hypotensive syndrome. Correcting maternal positioning is urgent to improve venous return and prevent adverse effects, then other assessments can follow.
Choice C rationale
Measuring blood pressure and pulse can confirm hypotension but does not address its cause. Immediate repositioning to lateral position alleviates the compression on the inferior vena cava, improving blood flow before measuring vitals.
Choice D rationale
Turning to a lateral position relieves the vena cava from compression by the gravid uterus, reducing symptoms of supine hypotensive syndrome. This action improves venous return, stabilizing maternal hemodynamics and alleviating dizziness and pallor.
Correct Answer is ["A","B","C","D","E"]
Explanation
Choice A rationale
Calculating the estimated date of birth involves determining the gestational age. Gestational age is crucial for monitoring fetal development and timing prenatal care.
Choice B rationale
Obtaining the client’s personal and family medical history helps identify genetic risks, potential complications, and health conditions that may affect pregnancy and delivery.
Choice C rationale
Obtaining information about prior pregnancies provides insight into potential risks and outcomes. Previous pregnancy complications can indicate risks for the current pregnancy.
Choice D rationale
Checking the client’s urine with a reagent strip screens for urinary tract infections, protein, and glucose levels. UTIs can cause complications, while protein and glucose levels help monitor maternal health.
Choice E rationale
Scheduling the client for prenatal laboratory testing, such as blood work and ultrasounds, helps assess maternal and fetal health. Tests like blood type, Rh factor, and infectious diseases are essential for prenatal care.
Choice F rationale
Discussing chorionic villus sampling is not necessary at 18 weeks of gestation. CVS is typically performed between 10-13 weeks for early genetic testing.
