Question 1

The patient at 18 weeks' gestation thinks she might have been exposed to a toxin at work that could affect fetal development. The patient asks the nurse what organs might be affected at this point in pregnancy. The best response by the nurse is:

Accepted Answer

At 18 weeks' gestation, the fetal brain is still developing and could be affected by exposure to toxins. It is important for the nurse to provide accurate information to help the patient make informed decisions about her health and the health of her developing baby.

Question 2

The nurse educator is presenting a program to college students about factors that can cause congenital malformations. She will tell them that:

Accepted Answer

The fetus is most vulnerable to toxic agents during the first months of pregnancy, particularly during the first trimester. This is because during this time, the major organ systems are developing rapidly and are therefore more susceptible to damage. Spontaneous abortion may or may not occur, depending on the severity of the insult. Toxic substances can include drugs, environmental pollutants, and infectious agents, among others.

Question 3

The nurse is presenting a class to pregnant patients. The nurse asks, "The fetal brain is developing rapidly, and the nervous system is complete enough to provide some regulation of body function on its own, at which fetal development stage?" It is clear that education has been effective when a participant responds:

Accepted Answer

The fetal brain develops rapidly, and the nervous system begins to regulate some body functions around the 25th-28th week of gestation.

Question 4

The OB-GYN nurse teaches a first-time pregnant patient that functions of the amniotic fluid include:

Accepted Answer

The answer of The OB-GYN nurse teaches a first-time pregnant...

Question 5

The nurse is teaching the significance of good nutrition on fetal development to a group of young women. Factors discussed will include:

Accepted Answer

Vitamins and folic acid are crucial for fetal development even before conception. Glucose, amino acids, and fatty acids play a significant role in the development and growth of the fetus throughout pregnancy. A high-fat diet is not essential, and complex carbohydrates and proteins are also important, but not the only essential nutrients. It's essential to maintain a healthy diet throughout pregnancy for optimal fetal development.

Question 6

A woman pregnant with twins asks the nurse about differences between identical and fraternal twins. The nurse explains that since it has been determined that she is having a boy and a girl, they are fraternal, and there will be:

Accepted Answer

Fraternal twins develop from two separate eggs that are fertilized by two different sperm. Therefore, they will have two placentas, two amnions (fluid-filled sacs that surround each fetus), and two chorions (outer membrane that surrounds each amnion).

Question 7

The nurse is holding a class for newly pregnant couples, and discussing good and bad influences on their baby. Prenatal influences on the intrauterine environment include which of the following?

Accepted Answer

The use of saunas or hot tubs, drugs, maternal nutrition, and vitamins and folic acid are all factors that can influence the prenatal environment. Saunas and hot tubs can raise the mother's core temperature, potentially harming the developing fetus. Drug use can lead to a range of developmental issues and birth defects. Maternal nutrition directly impacts fetal growth and development, while vitamins and folic acid are essential for preventing certain birth defects. The quality of the sperm or ovum, while important for conception and genetic material, is not considered a prenatal influence on the intrauterine environment as it predates the actual pregnancy.

Question 8

At her first prenatal visit, a woman is discussing fetal development with the nurse. The patient asks, "When will my baby actually have a heartbeat?" The nurse should reply, "The heartbeat of an embryo is distinguishable by:

Accepted Answer

The heartbeat of an embryo is distinguishable by the fourth week.

Question 9

During a prenatal examination, an adolescent patient asks, "How does my baby get air?" The nurse would give correct information by saying:

Accepted Answer

During pregnancy, the placenta provides oxygen and nutrients to the fetus through the umbilical cord. The placenta allows for the exchange of gases, such as oxygen and carbon dioxide, between the maternal and fetal blood supplies. Therefore, the correct statement would be that "the placenta assumes the function of the fetal lungs by supplying oxygen and allowing the excretion of carbon dioxide into your bloodstream."

Question 10

The nurse educator is teaching student nurses what a fetus will look like at various weeks of development. Which descriptions would be typical of a fetus at 20 weeks' gestation?

Accepted Answer

The answer of The nurse educator is teaching student nurses...

Question 11

The nurse teaching the expectant parents about the placenta also talks about the circulation and how the fetus gets its oxygen. She will include in this teaching which important fact?

Accepted Answer

The placenta functions as the lungs for the fetus by exchanging oxygen and carbon dioxide with the maternal bloodstream.

Question 12

The patient has read that the placenta produces hormones that are vital to the function of the fetus. It is evident that that the patient understands the function of the placenta when she states, "The hormone primarily responsible for the maintenance of pregnancy past the 11th week is:

Accepted Answer

Progesterone is the hormone primarily responsible for the maintenance of pregnancy past the 11th week. It helps to maintain the uterine lining, prevents contractions of the uterus, and supports fetal growth and development. HCG is important in the early stages of pregnancy, but its role decreases as progesterone takes over. HPL and estrogen are also produced by the placenta, but they have different functions in pregnancy.

Question 13

The pregnant patient who is at 14 weeks' gestation asks the nurse why the doctor used to call her baby an embryo, and now calls it a fetus. What is the best answer to this question?

Accepted Answer

A fetus is the term used from the ninth week of gestation and onward. Prior to that, the developing baby is referred to as an embryo.

Question 14

The nurse is working with a patient who has experienced a fetal death in utero at 20 weeks. The patient asks what her baby will look like when it is delivered. Which statement by the nurse is best?

Accepted Answer

At 20 weeks, a fetus is typically covered in fine hair called lanugo. The other options do not accurately describe the appearance of a fetus at this stage of development.

Question 15

A pregnant patient at 28 weeks' gestation asks the nurse what her baby is like at this stage of pregnancy. The nurse responds that the baby:

Accepted Answer

The answer of A pregnant patient at 28 weeks' gestation...
