A nurse in a provider's office is caring for a client who is at 36 weeks of gestation and scheduled for an amniocentesis. The client asks why she is having an ultrasound prior to the procedure. Which of the following is an appropriate response by the nurse?
"This will determine if there is more than one fetus."
"It assists in identifying the location of the placenta and fetus."
"This is a screening tool for spina bifida."
"It is useful for estimating fetal age."
The Correct Answer is B
Choice A: An ultrasound can indeed determine the number of fetuses if a client is carrying multiples, but this is not the primary reason for performing an ultrasound before amniocentesis.
Choice B: An ultrasound is typically done before an amniocentesis to visualize the location of the placenta and fetus. This information is important to ensure that the amniocentesis needle is safely inserted away from the placenta and the fetus.
Choice C: The primary purpose of an amniocentesis is to obtain a sample of amniotic fluid to screen for genetic conditions, not specifically for spina bifida.
Choice D: Fetal age can be estimated through an ultrasound, but this is not the primary reason for performing an ultrasound before an amniocentesis. The main goal of the procedure is to obtain a sample of amniotic fluid for genetic testing.

Correct Answer is A
Explanation
A) Quickening: Quickening is the term used to describe the first perception of fetal movements by the pregnant woman. It typically occurs between 16 to 20 weeks of gestation, which aligns with the client's statement about feeling fluttering movements at 18 weeks.
B) Ballottement: Ballottement is a physical examination technique performed by a healthcare provider to assess the fetus's position in the uterus. It is not related to the client's perception of fetal movement.
C) Chloasma: Chloasma refers to hyperpigmented skin areas that can appear during pregnancy due to hormonal changes. It is not related to fetal movement.
D) Lightening: Lightening refers to the descent of the fetal head into the maternal pelvis, which typically occurs in the third trimester. It is not related to the feeling of fetal movements by the mother.
Correct Answer is D
Explanation
Choice A: Smoking is not directly associated with the development of type 1 diabetes mellitus in the baby.
Choice B: While smoking during pregnancy can have various effects on the baby's health, hearing loss is not one of the common complications.
Choice C: Although smoking during pregnancy is associated with an increased risk of congenital heart defects, intrauterine growth restriction is a more likely complication based on the client's smoking history.
Choice D: Smoking during pregnancy is associated with various adverse outcomes for both the mother and the baby. It can cause intrauterine growth restriction (IUGR), where the baby does not grow at the expected rate and has a lower birth weight. Smoking reduces blood flow to the placenta, which can affect the baby's growth and development.
