Question 1

Infants born to African American mothers are more likely to have a low birthweight than infants born to Caucasian mothers.

Accepted Answer

This statement is true according to numerous studies and statistics. The reasons for this disparity can be multifactorial, including socio-economic factors, discrimination, access to healthcare, and genetic factors.

Question 2

​Approximately what proportion of infants who die within the first year of life die within the first month after birth?

Accepted Answer

According to global statistics, approximately 2/3 or 66% of infants who die within the first year of life die within the first month after birth.

Question 3

The rate of human growth and development is higher during gestation than at any time in life.

Accepted Answer

The rate of human growth and development is highest during gestation due to the rapid formation and differentiation of organs and tissues. After birth, growth still occurs but at a slower rate.

Question 4

​Infants weighing _____ are least likely to die within the first year of life.

Accepted Answer

Infants weighing between 7 lbs 12 oz to 10 lbs are considered to be within the normal birth weight range, which is associated with the lowest risk of infant mortality within the first year of life.

Question 5

Pregnancy weight-gain recommendations are the same for all women,regardless of their weight status before pregnancy.

Accepted Answer

Pregnancy weight-gain recommendations vary depending on a woman's pre-pregnancy weight status. Women who were underweight before pregnancy are recommended to gain more weight, while women who were overweight or obese before pregnancy are recommended to gain less weight.

Question 6

If not accompanied by hypertension,edema in pregnancy generally reflects a healthy expansion of plasma volume.

Accepted Answer

Edema in pregnancy is a common occurrence and is usually due to the increased plasma volume that occurs during pregnancy. This increased volume is necessary to support the growing fetus and prepare for delivery. If edema is not accompanied by hypertension, it is generally considered a normal and healthy part of pregnancy. However, if edema is severe or associated with other symptoms, such as high blood pressure, it may be a sign of a more serious medical condition and should be evaluated by a healthcare provider.

Question 7

Low levels of plasma volume expansion are associated with reduced fetal growth.

Accepted Answer

Plasma volume expansion is an important aspect of maternal adaptation during pregnancy. Low levels of plasma volume expansion can lead to reduced blood flow to the placenta, which can affect fetal growth and development. Studies have shown that inadequate plasma volume expansion is associated with an increased risk of intrauterine growth restriction (IUGR) and low birth weight babies.

Question 8

Maternal and fetal needs for protein are fulfilled by maternal protein and muscle stores entering pregnancy.

Accepted Answer

Maternal and fetal protein needs during pregnancy are primarily met through dietary intake, not solely from maternal protein and muscle stores.

Question 9

Insulin-like growth factor-1 is the primary growth stimulator of the fetus.

Accepted Answer

Insulin-like growth factor-1 (IGF-1) is a hormone that plays a crucial role in fetal growth and development. It stimulates the proliferation and differentiation of various types of cells, including muscle and bone cells, and is essential for the proper growth of the fetus.

Question 10

The fetus accounts for approximately 70% of the increased energy needs of pregnancy.

Accepted Answer

The fetus accounts for only a portion of the increased energy needs during pregnancy, with the rest attributed to factors like maternal tissue growth, increased metabolic rate, and energy storage.

Question 11

The highest rate of weight gain generally occurs during mid-pregnancy,prior to the time the fetus gains most of its weight.

Accepted Answer

This statement is true. The highest rate of weight gain for a pregnant person typically occurs during the second trimester, which is considered mid-pregnancy. During this period, the fetus is growing rapidly and the body is working hard to support its development. However, it's important to note that every pregnancy is different and weight gain patterns can vary based on the individual.

Question 12

​Even though the United States spends more money on health care than any other nation,the _____ rate ranks 56th among countries of the world.

Accepted Answer

The statement mentions the rank of the US among other countries in terms of a health indicator, and the only option provided which is a health indicator is infant mortality rate. Therefore, the correct choice is B.

Question 13

​Pre-term birth rate is defined as births less than _____ gestation per 100 live births.

Accepted Answer

The pre-term birth rate is defined as births less than 37 gestational weeks per 100 live births. Therefore, the correct choice is D.

Question 14

​Assessed from conception,pregnancy averages _____ weeks.

Accepted Answer

Pregnancy averages around 38 weeks, which is calculated from the first day of the woman's last menstrual period to the day of delivery.

Question 15

​The first half of pregnancy is considered the maternal _____ phase while the second half of pregnancy is considered the maternal _____ phase.

Accepted Answer

The first half of pregnancy is characterized by anabolic processes, such as tissue growth and an increase in blood volume. This is necessary for the development of the fetus. The second half of pregnancy involves catabolic processes, such as breaking down nutrients to supply energy for the fetus and preparing for labor and delivery. Therefore, choice D (anabolic;catabolic) is the best answer.

Question 16

Population-wide improvements in social circumstances,infectious disease control,and availability of _____ have corresponded to greater reductions in infant mortality than have technological advances in medical care.

Accepted Answer

The answer of Population-wide improvements in social circumstances,infectious disease control,and...

Question 17

Neural tube defects are among the most preventable types of congenital abnormalities that exist.

Accepted Answer

Neural tube defects can be prevented with proper maternal nutrition, particularly by ensuring adequate intake of folic acid before and during early pregnancy.

Question 18

Bioactive food components are constituents in foods or dietary supplements that are essential nutrients.

Accepted Answer

Bioactive food components are not necessarily essential nutrients, but they have the potential to promote health beyond their basic nutritional value. Examples include antioxidants, prebiotics, and phytochemicals.

Question 19

​The stages of development in chronological order are _____.

Accepted Answer

The stages of development in chronological order are embryo, fetus, and neonate.

Question 20

The maternal catabolic phase of pregnancy is marked by a decelerated fasting metabolism.

Accepted Answer

The maternal catabolic phase of pregnancy is actually marked by an accelerated fasting metabolism, as the mother's body breaks down stored fat to provide energy for the developing fetus.
