Question 1

One of the most important nutrients for infants in regions of high temperatures is supplemental water.

Accepted Answer

Supplemental water is essential for infants in regions of high temperatures to prevent dehydration and maintain proper hydration.

Question 2

Pregnant women require an additional 25 grams of protein per day compared with nonpregnant women.

Accepted Answer

During pregnancy, the body's need for protein increases to support fetal development, leading to a recommendation for pregnant women to consume an additional 25 grams of protein per day compared to their nonpregnant needs.

Question 3

Which characteristic is the single most potent indicator of an infant's future health status?

Accepted Answer

The infant's birthweight is the most potent indicator of an infant's future health status. Low birthweight can indicate potential health issues and developmental problems, while a healthy birthweight is generally a good sign of initial health and developmental prospects.

Question 4

Young children should be allowed to explore and enjoy food by eating with their fingers at first.

Accepted Answer

Eating with fingers allows young children to explore textures and tastes, helping to develop their sensory experiences and motor skills, which is important for their overall development.

Question 5

Which factor is critical in determining whether a mother can grow a healthy placenta during the first month of gestation?

Accepted Answer

The mother's nutrition before pregnancy is critical as it sets the foundation for a healthy pregnancy, including the development of the placenta. Proper nutrition ensures that the body has the necessary nutrients to support early fetal development.

Question 6

Breast milk contains less protein and more fat than milk recommended for adults.

Accepted Answer

Breast milk is specifically designed to meet the nutritional needs of infants, containing less protein and more fat compared to milk recommended for adults, which is crucial for the rapid brain development and growth occurring in the early stages of life.

Question 7

For a woman who begins her pregnancy at a healthy weight, the ideal weight-gain pattern during the first trimester is one pound per week.

Accepted Answer

During the first trimester, the recommended weight gain is typically 1 to 4 pounds in total, not per week.

Question 8

Which of the following health problems are low-birthweight babies likely to suffer from later in life?

Accepted Answer

The answer of Which of the following health problems are...

Question 9

Folate plays an important role in preventing neural tube defects.

Accepted Answer

Folate, a B-vitamin, is crucial for proper brain and spine development in embryos, and its adequate intake before and during early pregnancy helps prevent neural tube defects such as spina bifida and anencephaly.

Question 10

An embryo is the stage of human gestation from the third to the eighth week after conception.

Accepted Answer

The embryonic stage of human development occurs from the third to the eighth week after conception, following the zygote and blastocyst stages and preceding the fetal stage.

Question 11

The stage of human gestation from eight weeks after conception until the birth of an infant is called a(n):

Accepted Answer

The stage of human gestation from eight weeks after conception until the birth of the infant is referred to as the fetal stage, making "fetus" the correct term. Prior to this, the developing human is called an embryo.

Question 12

During pregnancy, consumption of certain types of fish is recommended as they are rich sources of:

Accepted Answer

Fish, especially fatty fish, are recommended during pregnancy because they are rich sources of omega-3 fatty acids, which are important for the development of the baby's brain and eyes.

Question 13

Which of the following statements is true regarding the nutrient intake of pregnant women?

Accepted Answer

During pregnancy, the demand for iron increases significantly to support the growing fetus and placenta, as well as to compensate for the blood loss during childbirth. This increased demand often cannot be met through diet alone, making iron supplements a common recommendation for pregnant women to prevent iron deficiency anemia.

Question 14

At eight weeks of development, the fetus has developed all of the following except :

Accepted Answer

At eight weeks of development, the fetus has begun to develop facial features, but they are not fully formed yet. The other options (a beating heart, a fully formed digestive system, well-defined fingers and toes, and a complete central nervous system) are all characteristics that are either fully developed or significantly underway by this stage.

Question 15

Physical activity during pregnancy can improve fitness, facilitate labor, and reduce psychological stress.

Accepted Answer

Moderate physical activity during pregnancy is beneficial for most women, as it can improve overall fitness, help with labor, and reduce psychological stress, according to guidelines from health organizations such as the American College of Obstetricians and Gynecologists.

Question 16

In gestational hypertension, blood pressure usually returns to normal during the first few weeks after childbirth.

Accepted Answer

Gestational hypertension typically resolves after the delivery of the baby, usually within the first few weeks postpartum as the body returns to its pre-pregnancy state.

Question 17

By adolescence, fatty streaks have formed in most children's coronary arteries.

Accepted Answer

Studies have shown that the process of atherosclerosis, or the buildup of fatty deposits in the arteries, begins early in life. Autopsy studies of young individuals, including children and adolescents who died of accidental causes, have revealed the presence of fatty streaks in the coronary arteries, indicating that the process of coronary artery disease begins in childhood.

Question 18

Consumption of fast-food meals on a daily basis does not increase the weight of obese children.

Accepted Answer

Regular consumption of fast-food meals is high in calories, fats, and sugars, which can contribute to weight gain and exacerbate obesity in children.

Question 19

Alcohol crosses the placenta and is directly toxic to the fetus.

Accepted Answer

Alcohol crosses the placenta and can directly harm the developing fetus by causing birth defects, developmental disorders, and other adverse outcomes.

Question 20

Spina bifida is characterized by incomplete closure of the spinal cord.

Accepted Answer

Spina bifida is a birth defect where there is incomplete closing of the backbone and membranes around the spinal cord.
