Question 1

At what week of fetal development can the nurse expect to first hear fetal heart tones with an amplified stethoscope?

Accepted Answer

During week 16,the fetal heart can be heard with an amplified stethoscope.

Question 2

A woman asks the nurse about the safety of sexual intercourse during her pregnancy.Which response by the nurse is the most correct?

Accepted Answer

Sexual activity should be ceased in the case of vaginal bleeding as it could indicate potential problems with the pregnancy such as threatened miscarriage or placenta previa. Sexual intercourse during pregnancy is generally safe as long as there are no complications and both partners are comfortable. It is important to speak with a healthcare provider about any concerns or questions regarding sexual activity during pregnancy.

Question 3

How long does the embryonic stage of pregnancy typically last?

Accepted Answer

The embryonic stage of pregnancy typically lasts for 8 weeks. During this stage, the fertilized egg divides into multiple cells and begins to develop into various organs and body systems. By the end of the embryonic stage, the majority of the major organs and body parts have formed.

Question 4

Why is the nurse concerned about a patient in her first trimester of pregnancy being exposed to German measles?

Accepted Answer

German measles, also known as rubella, can cause birth defects if contracted during the early stages of pregnancy. This is because the virus can cross the placenta and affect the developing fetus, leading to congenital rubella syndrome. This can result in a range of problems including deafness, blindness, heart defects, and intellectual disabilities. Therefore, the nurse is concerned about the potential exposure of a patient in her first trimester to this disease.

Question 5

A woman entering the 22nd week of pregnancy complains that she has become unsightly because of chloasma.What should the nurse recommend to reduce the appearance of the chloasma?

Accepted Answer

Chloasma, also known as the "mask of pregnancy," is a common condition that causes the development of brownish patches on the face, particularly on the forehead, cheeks, and nose. Sun exposure can worsen chloasma, so the nurse should recommend avoiding exposure to the sun and using a broad-spectrum sunscreen with an SPF of at least 30 when outside. Heavy makeup may cover up some of the discoloration, but it is not a solution for reducing the appearance of chloasma. Taking extra doses of vitamin A and reducing caffeine intake have no proven benefits in reducing the appearance of chloasma and may actually be harmful to the developing fetus.

Question 6

The nurse assures an anxious primigravida that during fetal development from week 34 and beyond,maternal antibodies are transferred to the baby.How long will these antibodies provide the baby with immunity?

Accepted Answer

Maternal antibodies transferred to the baby during fetal development from week 34 and beyond provide immunity for approximately 6 months after birth.

Question 7

Which hormone is secreted by the placenta?

Accepted Answer

Human chorionic gonadotropin (HCG) is a hormone that is secreted by the placenta after implantation. HCG is commonly used as a marker of pregnancy and is also the hormone that is detected by at-home pregnancy tests.

Question 8

Which is a positive sign of pregnancy?

Accepted Answer

A positive sign of pregnancy is an ultrasonic tracing of the fetus.A positive pregnancy test,positive Chadwick sign,and positive Goodell sign are all probable signs of pregnancy.

Question 9

A woman who has just discovered she is pregnant states that the first day of her last menstrual period was July 10.What will be her expected date of birth (EDB)?

Accepted Answer

Assuming a 28-day menstrual cycle, the expected due date will be April 17, calculated by adding 280 days (40 weeks) to the first day of the last menstrual period (July 10).

Question 10

A pregnant teenager presents with the following complaints.Which complaint could be an indicator of a serious complication?

Accepted Answer

Visual disturbances during pregnancy, especially when accompanied by other symptoms such as headache and high blood pressure, could be an indicator of serious conditions such as preeclampsia or eclampsia, which require immediate medical attention. Painful hemorrhoids, linea nigra, and low back pain are common complaints in pregnancy but do not necessarily indicate a serious complication.

Question 11

During the final weeks of pregnancy,urinary frequency may return due to the enlarged uterus,compressing the bladder against the pelvic bones.What does the nurse suggest to aid in relieving the urinary frequency?

Accepted Answer

Sleeping on the side can help relieve the pressure of the uterus on the bladder and decrease urinary frequency. Decreasing fluid intake or avoiding fluid intake in the evening may not be recommended as adequate hydration is important during pregnancy. The knee-chest position may be uncomfortable and not practical for long periods of time.

Question 12

What is the cause of frequent urination in early pregnancy?

Accepted Answer

During early pregnancy, the body's circulating blood volume increases to support the growing fetus, which can lead to more frequent urination as the kidneys filter this increased volume of blood.

Question 13

Where does implantation of the fertilized ovum usually occur?

Accepted Answer

Implantation of the fertilized ovum usually occurs in the fundus of the uterus, which is the top portion of the uterus. This area is well-vascularized and provides a favorable environment for the developing embryo. The lower uterine wall, side of the uterus, and body of the uterus are less likely locations for implantation to occur.

Question 14

What does the increase in circulating blood volume during pregnancy cause in the mother?

Accepted Answer

Maternal circulating volume increases 30% to 40%,causing a virtual decrease in hemoglobin.

Question 15

During which gestational week can a primigravida expect to first feel fetal movement?

Accepted Answer

Fetal movement, also known as "quickening," is typically first felt by primigravida (first-time mothers) between 16 and 20 weeks of gestation.

Question 16

What protects the fetus from most bacterial infections?

Accepted Answer

The placental barrier separates the maternal and fetal blood supplies, and it is effective at preventing most bacteria from crossing over to the fetus. The yolk sac, cotyledons, and chorionic villa are not as effective at providing this protection.

Question 17

Early in the first trimester,a woman complains of morning sickness.What does the nurse suggest to aid with the discomfort?

Accepted Answer

Eating dry crackers before getting up has been shown to help alleviate morning sickness. Eating something with a high-fat content may actually worsen nausea. Eating three well-balanced meals is ideal, but may not necessarily relieve morning sickness. Getting rest and taking antiemetics may help, but should be recommended by a healthcare provider.

Question 18

A woman tells the nurse that this is her third pregnancy.She has had twin girls at full term and one miscarriage.How does the nurse record the information?

Accepted Answer

The correct way to record the woman's pregnancy history is G3, T1, A1, L2. G3 indicates this is her third pregnancy (two previous pregnancies plus the current one), T1 indicates she has had one term pregnancy (the twin girls count as one term pregnancy), A1 indicates she has had one miscarriage, and L2 indicates she has given birth to two living children (the twin girls).

Question 19

What period of the maternity cycle does the intrapartal period cover?

Accepted Answer

The intrapartal period covers the onset of labor through the delivery of the placenta, encompassing the entire process of childbirth.

Question 20

A patient has been diagnosed with a tubal pregnancy.What is the typical outcome of a tubal pregnancy?

Accepted Answer

A tubal pregnancy is an ectopic pregnancy that occurs when the fertilized egg implants in the fallopian tube rather than in the uterus. This is a medical emergency that requires immediate surgical intervention to prevent rupture of the fallopian tube and potentially life-threatening bleeding. Therefore, the typical outcome of a tubal pregnancy is that the patient will require surgery to remove the zygote.
