Chapter 10: Nutrition during Pregnancy and Lactation

Question 1

Nutritional needs during pregnancy are affected by

a. the mother’s age.
b. the sex of the infant.
c. the mother’s food cravings.
d. whether the mother works

Answer 1

the mother’s age.

Question 2

A pregnant woman’s energy needs must be met in order to

a. spare vitamins.
b. spare adipose stores.
c. prevent fetal deformity.
d. spare protein.

Answer 2

spare protein.

Adequate energy is necessary to spare protein. If inadequate kilocalories from energy are provided, then protein will be used for energy. Protein increase is approximately 50% more than the average adult requirement.

Question 3

Daily kilocalorie needs during the second trimester exceed normal requirements by approximately _____ kcal.

a. 100
b. 200
c. 340
d. 500

Answer 3

340

The national standard recommends an increase of 340 kcal/day during the second trimester and approximately 450 kcal/day during the third trimester of pregnancy.

Question 4

The amount of extra protein required by pregnant versus nonpregnant women is approximately _____ g/day.

a. 10
b. 15
c. 25
d. 30

Answer 4

25

Protein intake should increase 25 g/day during pregnancy on top of nonpregnancy needs. This increase is approximately 50% more than the average adult requirements.

Question 5

Increased protein is necessary in pregnancy for

a. preventing gestational diabetes.
b. sparing carbohydrates for energy needs.
c. growing maternal tissues.
d. preventing pregnancy-induced hypertension.

Answer 5

growing maternal tissues.

Question 6

Three minerals that should be significantly increased during pregnancy are

a. calcium, iron, and iodine.
b. calcium, phosphorus, and zinc.
c. iron, zinc, and iodine.
d. calcium, sodium, and potassium.

Answer 6

calcium, iron, and iodine.

Calcium is essential for fetal development of bones and teeth as well as for the mother’s own body needs.
Iron is essential for the increased hemoglobin synthesis required for the greater maternal blood volume as well as for the baby’s necessary prenatal storage of iron.
Adequate iodine intake is essential for producing more thyroxine needed in greater amounts to control the increased basal metabolic rate during pregnancy.

Question 7

The recommended daily iron intake during pregnancy is _____ mg.

a. 12
b. 18
c. 27
d. 35

Answer 7

27

The recommended iron intake is 27 mg/day, which is significantly more than a woman’s normal need of 18 mg/day.

Question 8

Iron needs increase during pregnancy because of

a. maternal constipation.
b. increased maternal blood volume.
c. increased maternal metabolic rate.
d. poor iron absorption during pregnancy.

Answer 8

increased maternal blood volume.

Question 9

Adequate folate in the periconceptional period helps prevent

a. cretinism.
b. mental retardation.
c. neural tube defects.
d. gestational diabetes.

Answer 9

neural tube defects.

Folate builds mature red blood cells throughout pregnancy and is particularly needed during the early periconceptional period to ensure healthy embryonic tissue development and prevent malformation of the neural tube.

Question 10

The B-complex vitamins are required in greater amounts during pregnancy because

a. fetal demands for the vitamins are high.
b. more hemoglobin is synthesized.
c. the vitamins are excreted in greater quantities.
d. metabolic activities increase.

Answer 10

metabolic activities increase.

Question 11

Daily intake of vitamin C should be increased during pregnancy because it

a. is an important element in tissue growth.
b. plays an important role in protein synthesis.
c. is necessary for the energy-producing pathways.
d. is important in development of bones in the fetus.

Answer 11

is an important element in tissue growth.

Vitamins A and C are needed in higher amounts during pregnancy because they are both important elements of tissue growth.

Question 12

Drinking 3 to 4 cups of milk a day during pregnancy is recommended because it is a good source of

a. folate.
b. iron.
c. vitamin D.
d. vitamin C.

Answer 12

vitamin D.

Milk is a good source of vitamin D along with calcium, phosphorus, and magnesium for fetal development of bones and teeth as well as for the mother’s own body needs.

Question 13

c. a glass of hot decaffeinated tea with each meal.
d. whole-wheat toast with small amount of light butter and small piece of fruit.

Answer 13

whole-wheat toast with small amount of light butter and small piece of fruit.

Question 14

A condition of severe, prolonged, and persistent vomiting during pregnancy is called

a. hyperemesis gravidarum.
b. placenta previa.
c. hypergastritis.
d. hyperbulimia.

Answer 14

hyperemesis gravidarum.

is morning sickness in early pregnancy that progresses from a mild state to a severe and prolonged state requiring medical treatment.

Question 15

Constipation during pregnancy often is caused by

a. increased food intake.
b. increased milk intake.
c. intake of low-fiber foods.
d. placental hormones that cause intestinal muscles to relax.

Answer 15

placental hormones that cause intestinal muscles to relax.

Constipation during pregnancy often is caused by placental hormones that cause the intestinal muscles to relax. It usually is seen in the latter part of pregnancy when pressure on the enlarging uterus is increased.

Question 16

An acceptable ending pregnancy weight for a normal-weight woman whose prepregnancy weight is 125 lb is _____ lb.

a. 130 to 135
b. 135 to 145
c. 145 to 150
d. 150 to 160

Answer 16

150 to 160

Weight gain for a normal-weight woman with a body mass index of 19.8 to 26 is 25 to 35 lb. Thus 125 lb + 25 to 35 lb = 150 lb to 160 lb.

Question 17

Total weight gain during the first trimester should be approximately _____ lb.

a. 1 to 2
b. 2 to 4
c. 6 to 10
d. 10 to 15

a. less fluid retention.
b. rapid weight loss.
c. fewer maternal infections.
d. convenience and economy.

Answer 28

Question 29

During pregnancy, intake of caffeine for a 132-lb woman should be

a. avoided.
b. limited to 100 mg of coffee per day.
c. limited to 300 mg of coffee per day.
d. unlimited in quantity.

Answer 29

limited to 300 mg of coffee per day.\

The overall conclusion is that moderate amounts of caffeine (5 to 6 mg/kg/day) throughout the day do not have negative effects on reproduction or fetal health. Thus, 60-kg (132-lb)  5 = 300 mg of caffeine/day.

Question 30
