Question 1

All early pregnancy tests are based on:

Accepted Answer

Early pregnancy tests detect the presence of human chorionic gonadotropin (hCG) in a woman's urine or blood, which is produced by the placenta after a fertilized egg implants in the uterus.

Question 2

Three of your co-workers are pregnant.(It must be the water!)Jan is very thin; Betty is average weight; Ellen is plump.How much weight should Jan _____; Betty _____; and Ellen _____ each gain?

Accepted Answer

The guidelines for healthy weight gain during pregnancy vary depending on pre-pregnancy weight. Jan, being thin, should aim to gain around 40 pounds; Betty, being of average weight, should aim to gain between 25-35 pounds; Ellen, being plump, should aim to gain around 15 pounds. It is important to gain a healthy amount of weight during pregnancy to support the growth and development of the baby. Option A (each should gain all the weight she wants) and option E (each should gain as little as possible) are not healthy choices as they do not take into consideration the individual's pre-pregnancy weight and health. Option D (45: 20; lose 10) is not a healthy choice as losing weight during pregnancy is not recommended.

Question 3

Darkening of vaginal tissues and of cervical mucous membranes is a/an _____ sign of pregnancy?

Accepted Answer

Darkening of vaginal tissues and cervical mucous membranes is a probable sign of pregnancy, as it can be observed by a healthcare provider and is an indication of physiological changes associated with pregnancy.

Question 4

Although exposure at any time prenatally is potentially harmful,the baby is most vulnerable to the effects of teratogens:

Accepted Answer

During the first 2 to 3 months of pregnancy, the baby's major organs are developing and are thus most vulnerable to the harmful effects of teratogens. After this period, the organs and systems are more fully formed, so the risk of major structural damage decreases. However, exposure to teratogens later in pregnancy can still have negative effects on the baby's functioning and development.

Question 5

Morning sickness is a/an _____ sign of pregnancy?

Accepted Answer

Morning sickness is a presumptive sign of pregnancy, which means it indicates that a woman may be pregnant but does not confirm it.

Question 6

The due date for a pregnancy is calculated from the ______.

Accepted Answer

The due date for a pregnancy is calculated from the first day of the last menstrual period. This is because it is difficult to accurately determine the date of conception, but the first day of the last menstrual period is a date that most women can easily remember and track. The due date is estimated to be 40 weeks (or 280 days) from this date.

Question 7

According to U.S.Census statistics,

Accepted Answer

Women who intended to become pregnant are more likely to seek early prenatal care because they are more prepared and proactive about their pregnancy, unlike those with unwanted pregnancies who may delay seeking care.

Question 8

What percentage of women have their babies within a two-week period before or after the anticipated day of birth?

Accepted Answer

About 80% of women give birth within two weeks before or after their due date, as this is a common range for full-term pregnancies.

Question 9

Suzie should have started her menstrual period two days ago; she wonders if she is pregnant.She takes a home pregnancy test and gets a negative result.What does this mean?

Accepted Answer

It is possible that the test was taken too early to detect pregnancy hormones. Suzie should wait a few more days and then retest to ensure accuracy.

Question 10

Which ethnic/racial group has the highest rate of late/no prenatal care?

Accepted Answer

Native American women have the highest rate of late or no prenatal care compared to other racial/ethnic groups in the United States. This can be due to a variety of factors such as geographical isolation, cultural barriers, and lack of access to healthcare services in some rural areas.

Question 11

Ordinarily,which period of development is considered the MOST crucial to the good health of the fetus?

Accepted Answer

During the first 3 months of development, vital organs are forming and the fetus is most vulnerable to teratogens that can disrupt the development and result in birth defects. It is crucial for the mother to maintain good health practices such as nutrition, avoiding harmful substances, and managing stress during this period.

Question 12

Using Naegele's formula for calculating the expected date of birth involves:

Accepted Answer

Naegele's formula for calculating the expected date of birth involves subtracting 3 months from the first day of the last menstrual period and then adding 7 days.

Question 13

Presumptive signs of pregnancy include all EXCEPT which of the following?

Accepted Answer

Enlargement of abdomen and uterus is considered a positive sign of pregnancy, indicating that the fetus is growing and developing. Cessation of menstruation, frequent urination, and sleepiness are all presumptive signs, meaning they suggest the possibility of pregnancy but can also be caused by other factors.

Question 14

HCG is secreted by the placenta during pregnancy, making it a reliable indicator for pregnancy tests. It is not secreted by the other options listed.

Question 16

Any agent that disrupts prenatal development is called a:

Accepted Answer

A teratogen is any agent that can disrupt prenatal development and cause birth defects. Preeclampsia is a medical condition that occurs during pregnancy and is not a disruptor of prenatal development. Transverse agent and prepartum disruptor are not commonly used terms in the field of developmental psychology.

Question 17

Cessation of menstruation is a _____ sign of pregnancy.

Accepted Answer

Cessation of menstruation is considered a presumptive sign of pregnancy, as it can suggest pregnancy but is not definitive on its own, since there are other conditions that can cause a woman to miss her period.

Question 18

A positive sign of pregnancy is:

Accepted Answer

The fetal heartbeat is a positive sign of pregnancy because it is a definitive indication that a fetus is developing in the uterus. Positive pregnancy tests, enlargement of the abdomen and uterus, and Chadwick's sign are considered presumptive or probable signs of pregnancy, but they are not definitive because they can be caused by conditions other than pregnancy.
