Question 3

Born in India, Vihaan's mother gives birth to him before the end of week 22.Vihaan will probably __________.

Accepted Answer

Babies born before 22 weeks have a very low chance of survival, often around 0-5%.

Question 4

Accepted Answer

The fetus's heartbeat can be heard with a stethoscope during the third month of pregnancy. This is typically around week 9-12. Hearing the heartbeat can provide reassurance to expectant parents that the fetus is developing properly.

Question 5

Accepted Answer

The answer of The __________ form at the end of...

Question 6

Prenatal development is divided into three segments called __________.

Accepted Answer

Prenatal development is divided into three trimesters, each lasting approximately three months. These trimesters are used to track the development of the fetus and changes in the mother's body.

Question 7

Question 9

What period lasts from the ninth week after conception until birth?

Accepted Answer

The fetal period lasts from the ninth week after conception until birth. During this time, the fetus continues to grow and develop, with organs completing their development and becoming functional. This is the longest period of prenatal development.

Question 10

Accepted Answer

By the end of the third month of pregnancy, the baby's genitalia have fully formed, making it possible to learn the sex of the baby through ultrasound imaging.

Question 12

Newborns weighing less than __________ are at risk for a wide range of developmental difficulties.

Accepted Answer

Newborns weighing less than 5.5 pounds (2.5 kg) are considered to have low birth weight and are at risk for a wide range of developmental difficulties including respiratory distress, infections, feeding difficulties, and learning disabilities. It is important to identify these newborns early and provide appropriate care and support to help them meet their developmental milestones.

Question 13

Sylvia has had her first pregnancy check-up and is just starting her second month of pregnancy.She is very upset that she has not been given the chance to hear her fetus's heartbeat.Remembering what you learned in your human development class, what should you tell Sylvia?

Accepted Answer

Typically, the fetal heartbeat can be heard with a stethoscope around the third month of pregnancy. It is not necessarily a cause for concern that Sylvia was not able to hear the heartbeat during her first check-up in her second month of pregnancy.

Question 14

The __________ are the last major organ system to develop during fetal life.

Accepted Answer

The lungs are the last major organ system to develop during fetal life. They begin to form during the embryonic stage and continue to develop throughout pregnancy, with surfactant production and alveolarization occurring in the last trimester. The kidneys begin to develop around week 5 and are functioning by week 9, while the intestines and skeletal muscles begin to form during the fetal period but are well-developed by mid-pregnancy.

Question 15

The purpose of lanugo, the downy hair that covers the fetus, is to __________.

Accepted Answer

Lanugo helps the vernix caseosa, a waxy or cheese-like white substance, stick to the fetus's skin. This combination provides a protective layer that guards against chapping and abrasion, as well as provides some control over the fetus's body temperature.

Question 16

Anong is talking to her friend, who is at the end of her second trimester.Luciana wants to be reassured that she is not crazy, but she thinks her baby actually kicks, turns, and hiccups.Luciana even thinks that the baby becomes more active if she talks to it.If you were Anong, how would you respond to Luciana's observations?

Accepted Answer

The oily, cheesy substance on the baby's skin is called vernix and is a normal occurrence for many babies at birth. It is produced by the baby's skin to protect their skin from the amniotic fluid in utero. It is important to reassure the colleague that this is a normal and healthy part of the baby's development.

Question 18

A pregnant woman typically begins to feel the movements of her fetus by the end of the __________ month.

Accepted Answer

The movements of a fetus, often referred to as "quickening," are typically first felt by a pregnant woman around the end of the fourth month of pregnancy. This can vary from woman to woman but is a general timeframe.

Question 19

The term used to describe the fetus's likelihood of surviving outside of the uterus if born preterm or prematurely is called __________.

Accepted Answer

Viability refers to the ability of a fetus to survive outside of the uterus. Generally, this occurs around 24 weeks of gestation, although it can vary depending on various factors such as the health of the mother and fetus. The other options, survival index, gestation, and neurogenesis, are not terms used to describe the fetus's likelihood of surviving outside of the uterus if born preterm or prematurely.

Question 20

What do fetuses do when their mothers are highly stressed?

Accepted Answer

When mothers are highly stressed, fetuses tend to move more in the womb and may also show increased heart rates. This is because the fetus is responding to the stress hormones released by the mother, which can cross the placenta and affect the developing baby's physiological state.
