At 35 weeks of pregnancy a woman experiences preterm labor. Tocolytics are administered and she is placed on bed rest, but she continues to experience regular uterine contractions, and her cervix is beginning to dilate and efface.

What would be an important test for fetal well-being at this time?
a. Percutaneous umbilical blood sampling (PUBS)
b. Ultrasound for fetal size
c. Amniocentesis for fetal lung maturity
d. Nonstress test (NST)

Question 2

A newly pregnant patient visits her provider's office for the first prenatal appointment.

To estimate accurate weight gain throughout the pregnancy, the nurse will be evaluating the appropriateness of weight for height using the body mass index (BMI). The patient weighs 51 kg and is 1.57 m tall.
The BMI is:

Answer to Question 1

ANS: C
Amniocentesis would be performed to assess fetal lung maturity in the event of a preterm birth. Indications for PUBS include prenatal diagnosis or inherited blood disorders, karyotyping of malformed fetuses, detection of fetal infection, determination of the acid-base status of a fetus with intrauterine growth restriction, and assessment and treatment of isoimmunization and thrombocytopenia in the fetus. Typically, fetal size is determined by ultrasound during the second trimester and is not indicated in this scenario. NST measures the fetal response to fetal movement in a noncontracting mother.

Answer to Question 2

ANS:
20.7
BMI = weight divided by height squared. BMI = 51 kg/(1.57m)2, or 20.7. Prepregnant BMI can be classified into the following categories: <18.5, underweight or low; 18.5-24.9, normal; 25-29.9 overweight or high; and >30, obese
