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 C
Explanation
A: Administering glucocorticoids intramuscularly is indicated for enhancing fetal lung maturity in cases of anticipated preterm birth. However, the client is at 38 weeks of gestation, which is not considered preterm, and the elevated temperature is the main concern.
B: Preparing the client for an emergency cesarean section based solely on an elevated temperature is not an appropriate action. There may be other factors contributing to the temperature elevation, and further assessment is needed.
C: An elevated temperature during pregnancy can indicate infection, which is a concern when the client's membranes have ruptured (premature rupture of membranes or PROM). Before any
interventions are initiated, the nurse should assess the odor of the amniotic fluid as it can provide important information about possible infection. If the amniotic fluid has a foul odor or appears
cloudy, it may indicate infection and require prompt medical attention.
D: Rechecking the client's temperature in 4 hours is not the appropriate immediate action when an elevated temperature is observed, especially in a pregnant woman.
Correct Answer is D
Explanation
A) Retained bile in the liver results in delayed digestion: This statement is not related to the cause of heartburn.
B) Increased estrogen production causes increased secretion of hydrochloric acid: While hormonal changes during pregnancy can contribute to heartburn, it is specifically increased progesterone that leads to relaxation of the cardiac sphincter and delayed gastric emptying, which are more directly linked to heartburn.
C) Pressure from the growing uterus displaces the stomach: Uterine pressure on the stomach can lead to a feeling of fullness, but it is not the primary cause of heartburn during pregnancy.
D) Increased progesterone production causes relaxation of the smooth muscle relaxation of the cardiac sphincter and delayed gastric emptying: This is the correct answer. Increased progesterone levels during pregnancy relax the lower esophageal sphincter, leading to gastric acid reflux into the esophagus and causing heartburn.
