A nurse in a provider's office is caring for a client who is at 36 weeks of gestation and is scheduled for an amniocentesis.
The client asks why she is having an ultrasound prior to the procedure.
Which of the following responses by the nurse is appropriate?
"This is a screening tool for spina bifida.”.
"It is useful for estimating fetal age.”.
"It assists in identifying the location of the placenta and fetus.”.
"This will determine if there is more than one fetus.”. .
The Correct Answer is C
Choice A rationale:
"This is a screening tool for spina bifida.”. This statement is incorrect. An ultrasound performed before an amniocentesis is not primarily used as a screening tool for spina bifida. Spina bifida can be detected through other diagnostic tests.
Choice B rationale:
"It is useful for estimating fetal age.”. While ultrasounds can provide information about fetal age, it is not the primary reason for performing an ultrasound before an amniocentesis. The main purpose is to identify the location of the placenta and fetus, which is essential for safely performing the amniocentesis procedure.
Choice C rationale:
"It assists in identifying the location of the placenta and fetus.”. This is the correct answer. An ultrasound before amniocentesis is crucial for locating the fetus and the placenta accurately. This information helps healthcare providers ensure the safe and precise insertion of the needle into the amniotic sac.
Choice D rationale:
"This will determine if there is more than one fetus.”. Determining if there is more than one fetus is an important aspect of prenatal care but is not the primary reason for performing an ultrasound before amniocentesis. It is generally confirmed through earlier ultrasounds during routine prenatal care. .

Correct Answer is B
Explanation
Choice A rationale:
Maternal/newborn blood group incompatibility can lead to jaundice in newborns, but it typically occurs within the first 24 hours of life. In this scenario, the baby is delivered 12 hours ago, and the yellowing of the skin is described as "slight.”. Physiologic jaundice, which occurs in the majority of newborns, typically appears on the second or third day after birth, so this choice is less likely.
Choice B rationale:
Physiologic jaundice is the most likely cause of the slight yellowing of the newborn's skin. It typically appears on the second or third day after birth and is related to the immature liver's inability to efficiently process bilirubin. Physiologic jaundice is a common and self-limiting condition that does not usually require treatment.
Choice C rationale:
Maternal cocaine abuse can lead to various neonatal complications, but it is not typically associated with jaundice. The yellowing of the skin in this scenario is more likely related to another cause.
Choice D rationale:
Correct Answer is D
Explanation
Choice A rationale:
The instruction to "cover the cord with the diaper" is incorrect. It's essential to keep the umbilical cord stump dry and exposed to air to promote healing. Covering it with a diaper can trap moisture and increase the risk of infection.
Choice B rationale:
The recommendation to "wrap the cord in petroleum jelly gauze" is not appropriate. Applying petroleum jelly or other ointments to the cord stump is not recommended, as it can also trap moisture and create an environment for bacterial growth.
Choice C rationale:
The instruction to "bathe the newborn with a washcloth until the cord stump falls off" is not the best practice. It's advisable to give sponge baths and avoid submerging the cord stump until it has completely dried and fallen off. Using a washcloth may cause unnecessary friction and irritation.
Choice D rationale:
The advice to "wash the cord daily with mild soap and water" is the correct instruction. Cleaning the cord stump with mild soap and water and then gently patting it dry with a clean cloth is a standard practice for cord care. Keeping the area clean helps prevent infection and promotes healing.
