Question 1

The patient at 14 weeks' gestation has undergone a transvaginal ultrasound to assess cervical length. The ultrasound revealed cervical funneling. How should the nurse explain these findings to the patient? "Your cervix:

Accepted Answer

Cervical funneling is when the cervical opening widens at the end near the baby, creating a cone-shape. This can be a concern for premature labor, but it does not necessarily mean that the patient will deliver early.

Question 2

The nurse knows that a lecithin/sphingomyelin (L/S) ratio finding of 2:1 on amniotic fluid means:

Accepted Answer

A L/S ratio of 2:1 on amniotic fluid indicates that fetal lungs are mature.

Question 3

The pregnant patient and her partner are both 40 years old. The nurse is explaining the options of chorionic villus sampling (CVS) and amniocentesis for genetic testing. The nurse should correct the patient if she states:

Accepted Answer

Amniocentesis results typically take 1-2 weeks, while CVS results can be available within a few days to a week, making the statement that amniocentesis results are available sooner incorrect.

Question 4

The nurse anticipates that the physician will most likely order a cervico-vaginal fetal fibronectin test for which patient?

Accepted Answer

The cervico-vaginal fetal fibronectin test is used to assess the risk of preterm labor in women experiencing regular uterine contractions before 37 weeks' gestation. Therefore, the patient at 32 weeks' gestation with regular uterine contractions is the most likely candidate for this test.

Question 5

The patient and her partner are carriers of sickle-cell disease. They are considering prenatal diagnosis with either amniocentesis or chorionic villus sampling (CVS). Which statements indicate that further teaching is needed on these two diagnostic procedures?

Accepted Answer

The answer of The patient and her partner are carriers...

Question 6

A 28-year-old woman has been an insulin-dependent diabetic for 10 years. At 36 weeks' gestation, she has an amniocentesis. A lecithin/sphingomyelin (L/S) ratio test is performed on the sample of her amniotic fluid. Since she is a diabetic, the 2:1 ratio obtained indicates that the fetus:

Accepted Answer

The L/S ratio is a measure of fetal lung maturity. A ratio of 2:1 or greater indicates that the fetal lungs are mature enough to function outside of the womb. However, since the mother is a diabetic, there may be an increased risk of fetal lung immaturity. Therefore, it is important to monitor the fetus closely and be prepared to provide respiratory support if necessary.

Quiz 21: Assessment of Fetal Well-Being

The patient at 14 weeks' gestation has undergone a transvaginal ultrasound to assess cervical length. The ultrasound revealed cervical funneling. How should the nurse explain these findings to the patient? "Your cervix:

The nurse knows that a lecithin/sphingomyelin (L/S) ratio finding of 2:1 on amniotic fluid means:

The pregnant patient and her partner are both 40 years old. The nurse is explaining the options of chorionic villus sampling (CVS) and amniocentesis for genetic testing. The nurse should correct the patient if she states:
