Already Graded.
Women with an inadequate weight gain during pregnancy are at higher
risk of giving birth to an infant with:
A. spina bifida.
B. intrauterine growth restriction
C. diabetes mellitus.
D. Down syndrome.
Correct Answer -B-
An adequate amount of folic acid has been shown to reduce the incidence
of this condition. Both normal-weight and underweight women with
inadequate weight gain have an increased risk of giving birth to an infant
with intrauterine growth restriction. Diabetes mellitus is not related to
inadequate weight gain. A gestational diabetic mother is more likely to give
birth to a large-for-gestational age infant. Down syndrome is the result of a
trisomy 21, not inadequate maternal weight gain.
Which minerals and vitamins usually are recommended to supplement a
pregnant woman's diet?
A. Fat-soluble vitamins A and D
B. Water-soluble vitamins C and B6
C. Iron and folate
D. Calcium and zinc
Correct Answer -c- Fat-soluble vitamins should be supplemented as a
,medical prescription, as vitamin D might be for lactose-intolerant women.
Water-soluble vitamin C sometimes is consumed in excess naturally;
vitamin B6 is prescribed only if the woman has a very poor diet. Iron
generally should be supplemented, and folic acid supplements often are
needed because folate is so important. Zinc sometimes is supplemented.
Most women get enough calcium.
With regard to nutritional needs during lactation, a maternity nurse should
be aware that:
A. the mother's intake of vitamin C, zinc, and protein now can be lower
than during pregnancy.
B. caffeine consumed by the mother accumulates in the infant, who
therefore may be unusually active and wakeful.
C. critical iron and folic acid levels must be maintained.
D. lactating women can go back to their prepregnant calorie intake.
Correct Answer -B- Vitamin C, zinc, and protein levels need to be
moderately higher during lactation than during pregnancy. A lactating
woman needs to avoid consuming too much caffeine. The
recommendations for iron and folic acid are somewhat lower during
lactation. Lactating women should consume about 500 kcal more than
their prepregnancy intake, at least 1800 kcal daily overall.
When counseling a client about getting enough iron in her diet, the
maternity nurse should tell her that:
A. milk, coffee, and tea aid iron absorption if consumed at the same time
as iron.
B. iron absorption is inhibited by a diet rich in vitamin C.
C. iron supplements are permissible for children in small doses.
,D. constipation is common with iron supplements.
Correct Answer -d- These beverages inhibit iron absorption when
consumed at the same time as iron. Vitamin C promotes iron absorption.
Children who ingest iron can get very sick and even die. Constipation can
be a problem.

to test for human chorionic gonadotropin (hCG)?
A. Radioimmunoassay
B. Radioreceptor assay
C. Latex agglutination test
D. Enzyme-linked immunosorbent assay (ELISA)
Correct Answer -d-

Cardiovascular system changes occur during pregnancy. Which finding
would be considered normal for a woman in her second trimester?
A. Less audible heart sounds (S1, S2)
B. Increased pulse rate
C. Increased blood pressure
D. Decreased red blood cell (RBC) production
Correct Answer -b-Splitting of S1 and S2 is more audible.
between 14-20 weeks of gestation.the pulse increases about 10 to 15
beats/min, which persists to term. In the first trimester blood pressure
usually remains the same as the prepregnancy level, but it gradually
decreases up to about 20 weeks of gestation. During the second trimester
both the systolic and diastolic pressures decrease by about 5 to 10 mm Hg.
Production of RBCs accelerates during pregnancy
A woman who has completed one pregnancy with a fetus (or fetuses)
reaching the stage of fetal viability is called a:
A. primipara
B. primigravida
C. multipara.
D. nulligravida.

pregnancy with a viable fetus. To remember terms, keep in mind that
gravida is a pregnant woman; para comes from parity, meaning a viable
fetus;primi means first; multi means many; and null means none. A
