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.

Answer and Explanation

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

Enlarged uterus is a probable sign of pregnancy, often caused by uterine growth. Probable signs are those observed by the examiner but not definite.

Choice B rationale

Positive fetal cardiac activity on ultrasound is a positive sign of pregnancy. Positive signs are definitive proof of pregnancy, observed via imaging or hearing fetal heart tones.

Choice C rationale

Auscultation of fetal heart tones is a positive sign of pregnancy, indicating fetal presence. Positive signs confirm pregnancy through direct observation or hearing the fetus.

Choice D rationale

Amenorrhea is a presumptive sign of pregnancy, commonly due to hormonal changes. Presumptive signs are subjective symptoms experienced by the woman, like nausea or breast tenderness.

A. A high-protein, low-carbohydrate diet may help keep your weight gain under control. B. You are eating for two now, but breastfeeding can help you lose excess weight later. C. Gaining 1 lb (0.5 kg) per week in this stage of pregnancy is important and expected. D. You can exercise daily, so you don’t have to worry about weight gain.

Correct Answer is C

Explanation

Choice A rationale

High-protein, low-carbohydrate diets are not recommended during pregnancy as they can lead to ketone production, which may harm fetal development. A balanced diet is crucial for maternal and fetal health.

Choice B rationale

Although breastfeeding can help with postpartum weight loss, it is not advisable to use pregnancy as a reason to overeat. Healthy weight gain during pregnancy is essential for fetal development.

Choice C rationale

Gaining 1 lb (0.5 kg) per week is recommended during the second trimester for a client with a normal BMI to ensure proper fetal growth and development.

Choice D rationale

Exercise is beneficial, but it cannot prevent all weight gain during pregnancy. Appropriate weight gain is necessary for fetal health and development.
